Here is an example : http://jsfiddle.net/xhhLja7m/ $(".choice-option").click(function() { $(this).find('input[type=radio]').prop("checked", "true"); }) ... First you need to get your timestamps in to Date() objects, which is simple using the constructor. If you want to update session when user does something on your page, you should create a ajax request to the server. 公式）This method is like _.find except that it iterates over elements of collection from right to left. Please can someone help me understand the exec method for regular expressions? _.flatMapDeepと使い方は似ているが、指定された回数だけ結果がフラットされる点が違う。depthのデフォルト値は1なので、何も指定しなければ_.flatMapと同じになる。. you need to refer to property "name" in the object obj.roles[0].name Another problem is that var finalXML get a new value every line. 公式）Iterates over elements of collection, returning an array of all elements predicate returns truthy for. It is not a beginners guide on lodash, or javaScript in general. Iteration is stopped once predicate returns falsey. There are many developers that consider lodash a dead utility library because a lot of functionality in lodash is now native in core javaScript itself. Gracias a @thefourtheye, tu código fue de gran ayuda.Creé una function genérica a partir de su solución utilizando la versión 4.5.0 de Lodash. The corresponding value of Using the same client, try this server code in your connection handler: socket.on('message', function(data) { // data === "pressed", since that's what the client sent console.log("Pressed! lodash 3系と4系は、主に contains => includes の breaking change で壊れがちなのですが、それさえ気をつければ3系への移行は簡単です。 不安な場合、 TypeScript と @types/lodash の導入で型チェックしながら置き換えるといいかもしれません。 So, your server.js would look like this // set up ====================================================================== var express = require('express'); var app = express(); // create our... javascript,knockout.js,requirejs,knockout-components. Lodash allows you to install its modules one-by-one (npm i lodash.groupby); I believe in this way you will get shorter, more maintainable code with clear functions. This is most likely the cause for some images to fail to receive a proper dataUrl. I assume that you have at least some background in javaScipt, and are researching lodash wondering if it is something that you should bother with or not. It's a matter of time. 公式）Creates a flattened array of values by running each element in collection thru iteratee and flattening the mapped results. The iteratee is invoked with three arguments: (value, index|key, collection). The predicate is invoked with three arguments: (value, index|key, collection). 配列またはオブジェクトの左から処理を実行していく。その時、累積した値と処理が実行されるため、単一の値に減らして返す。第三引数の[accumulator]の戻り値の形式を自由に選択できるので、[accumulator]には数値やboolean等も使える。 公式）Gets a random element from collection. The only purpose of this file would be to run the server. Instead of going for recursive, you can try this: classPromise = array.map(function(obj){ return obj.save();}); in es6, same thing can be: classPromise = array.map(obj => obj.save()); Edit You can reduce the whole function to: function myFunction(array, value) { if ( !array || !array.length) return; console.log("array: " + array.length); if (!value) value... Ok, so i tried to decypher what you meant with your Question. Iteration is stopped once predicate returns truthy. Why not register and get more from Qiita? Try wp_logout() function use the funtion . So you never get the value. I've just updated your jsfiddle: http://jsfiddle.net/0sq2rfcx/8/ This should work on all browsers included IE7 $('#b1').click(function () { $('#result').show(); $("#result").animate({ scrollTop:$('#a1').parent().scrollTop() + $('#a1').offset().top - $('#a1').parent().offset().top}, "slow"); }); $('#b2').click(function () { $('#result').show(); $("#result").animate({ scrollTop:$('#a2').parent().scrollTop() + $('#a2').offset().top - $('#a2').parent().offset().top}, "slow"); }); $('#b3').click(function () { $('#result').show();... the first "A" in AJAX stands for "Asynchronous" that means, it is not executed right after it has been called. I think you meant either one of those values, in that case var arr = ['bat', 'ball']; var selectors = arr.map(function(val) { return ':contains(' + val + ')' }); var $lis = $('ul li').filter(selectors.join()); $lis.css('color', 'red')

Help us understand the problem. setTimeout() is here a good choice, because of the single interval of waiting. 指定した[iteratee=.identity]（値または関数）を実行して、結果をkeyとしたオブジェクトを生成する。 The handler for each type of event is passed a certain set of arguments. 指定した値がコレクション内にあるかチェックし、あればtrue、なければfalseを返す。コレクションが文字列だった場合、引数で渡した文字列に１文字でも合致していればtrueを返す。. mit lodash.groupBy. By following users and tags, you can catch up information on technical fields that you are interested in as a whole, By "stocking" the articles you like, you can search right away. 公式）This method is like _.flatMap except that it recursively flattens the mapped results. Ie: Chart1.series.items[0].format.stroke.size=2; To modify the series color, change the series format.stroke.fill property. If collection is a string, it's checked for a substring of value, otherwise SameValueZero is used for equality comparisons. The corresponding value of each key 配列の要素に渡した関数を適用した後の結果を展開し、最終結果は連結してフラットになって返ってくる。. Save anonymous (public) fiddle? // latest 3.7.0 var _ = require (' lodash '); /** * lodash（Underscore.js） の便利な関数ライブラリたち * 「_」というオブジェクトを使用することにより利用可能 * 配列、オブジェクト操作を便利にするもの * * よく使うのは以下 * each * find * filter * where * findWhere * contains * pluck * … _.groupBy(collection, [iteratee=_.identity]) 配列から、繰り返し実行された処理の結果を、結果をkey、該当する値を配列にして返す。 公式）Creates an object composed of keys generated from the results of running each element of collection thru iteratee. Also methods like group by does bring som… You should change your row data.addColumn('String', 'sitecode'); to data.addColumn('string', 'sitecode'); (non capital "s" in "string"), of course this applies to all of your added columns. 配列またはオブジェクトから、指定した条件に合致する値以外を返す。_.filterと返ってくる値が逆。. Try like this angular.module('AngApp', ['angularGrid','restangular']); ... Use onbeforeunload function of javascript window.onbeforeunload = function() { //Declare cookie to close state } This function will be called every time page refreshes Update: To make loop through every value use this $.each this way: var new_value = ""; window.onbeforeunload = function() { $.each($('div.box_container div.box_handle'),function(index,value){ new_value = ($(value).next('.box').css('display') ==... EMI and CustomerName are elements under json so you can use .find() to find those elements and then text() to get its value. Javascript is case-sensitive.... Having a Line series: To modify the line thickness, change the series format.stroke.size property. Lodash helps in working with arrays, collection, strings, objects, numbers etc. The client doesn't get to cause arbitrary events to fire on the socket. Create a separate file called app.js. _.everyは使い方は_.someに近いが、全ての条件を満たさないとtrueを返さない。. Or maybe use some client side variables that, for some aspects, are similar to session (they will be forever... obj.roles[0] is a object {"name":"with whom"}. Without custom logic, it's not possible to achieve what you want. サンプル用のデータを適当に作る。 余談だが、本題に入る前に Pandas の二次元データ構造 DataFrame について軽く触れる。余談だが Pandas は列志向のデータ構造なので、データの作成は縦にカラムごとに行う。列ごとの処理は得意で速いが、行ごとの処理はイテレータ等を使って Python の世界で行うので遅くなる。 DataFrame には index と呼ばれる特殊なリストがある。上の例では、'city', 'food', 'price' のように各列を表す index と 0, 1, 2, 3, ...のように各行を表す index がある。また、各 index の要素を labe… To Clarify: He has this one page setup. 公式）Gets the size of collection by returning its length for array-like values or the number of own enumerable string keyed properties for objects. If the height or width of the canvas is 0, the string "data:," is returned. The iteratee is invoked with three arguments: Lodash’s modular methods are great for: Iterating arrays, objects, & strings Manipulating & testing values Lodash is The i++ is using post increment, so the value of the expression i++ is what the value was in the variable i before the increment. If you don't "override" the loadComponent method then the default component loader's loadComponent will be invoked which only calls the loadViewModel if you've provided a viewModel config option. Wie füge ich eigene Schlüssel für gruppierte Ausgaben hinzu? 公式）Creates an array of elements, sorted in ascending order by the results of running each element in a collection thru each iteratee. Your PHP is checking if $_POST['submit'] contains a value. Here is the incoming JSON layout. The iteratee is invoked with one argument: (value). if($_GET['logout'] == 1) { ob_start(); error_reporting(0); wp_logout(); $redirect = wp_logout_url(); wp_safe_redirect( $redirect ); } ... As PM 77-1 suggests, consider using the built–in Array.prototype.sort with Date objects. The order of grouped values is determined by the success(function(data) { $scope.news=data }). コレクションが渡した条件を一つでも満たしていればtrueを返す。 At the moment when you call var timer = setTimeout(slideshow, 8000); slideshow is undefined , and undefined is not a valid argument for setTimeout. Your form does not contain a form element with the attribute name="submit", so therefore it fails and moves straight to the else statement. The corresponding value of each key is an array of elements responsible for generating the key. The order of grouped values is determined by the order they occur in collection. Lodash is a JavaScript library that works on the top of underscore.js. Of course you can use this code multiple times. The corresponding value of each key is the number of times the key was returned by iteratee. (value, index|key, collection). Matches $99 $.99 $9.99 $9,999 $9,999.99 Explanation / # Start RegEx \$ # $ (dollar sign) ( # Capturing group (this is what you’re looking for) (? If null safety is critical for your application, we suggest that you take extra Array I guess OP wants to link the button more with corresponding click span class $('.clickme').click(function(){ $(this).parent().prev().find(".click").toggle(); }); FIDDLE DEMO... Ok, you'll want to check out Structuring your application. The iteratee is invoked with one argument: (value). Introduction lodash-php is a PHP utility library, similar to Underscore/Lodash, that utilizes namespaces and dynamic auto loading to improve library performance. Many lodash methods are guarded to work as iteratees for methods like _.reduce, _.reduceRight, and _.transform. Underscore.js groupBy multiple values (6) A simple recursive implementation: _.mixin({ /* * @mixin * * Splits a collection into sets, grouped by the result of running each value * through iteratee. var obj = {}; // Initialize the object angular.forEach(data, function(value, key) { if (value.start_date > firstdayOfWeek && value.start_date < lastdayOfWeek) { if (obj[value.firstname]) { // If already exists obj[value.firstname] += value.distance;... ofcservices.getnews() is a promise You need manage with the function sucess and error ofcservices.getnews(). The documentation for the latter mentions these parameters: -n, --end-with-newline -p, --preserve-newlines If you can force Adobe Brackets to pass parameters to the js-beautify call, I guess one of these should do the trick. 配列はlength、Stringは文字数。. ES6のforEachと同じ。[iteratee=_.identity]で指定した関数をループして処理する。return false で break。. Assuming the interval is between 1 and 15 seconds and changed after each interval. Test your JavaScript, CSS, HTML or CoffeeScript online with JSFiddle code editor. This is a post on a single lodash collection method called _.groupBy in the javaScript utility library known as lodash. However I believe you could find a compromise by using ES6 modules instead of CommonJS modules. KnockoutJS custom component loader not executing `loadViewModel`, Error: [$injector:unpr] Unknown provider: RestangularProvider, slideToggle state not working with multiple boxes, Automatically calling server side class without, How to send current page number in Ajax request, Javascript function to validate contents of an array, Dynamically resize side-by-side images with different dimensions to the same height, Not able to access variables in required file, Can't call fetch directly in Backbone model listenTo, session value in javascript cannot be set, Replacing elements in an HTML file with JSON objects, want to show and hide text using “this” jquery, Insert data in collection at Meteor's startup, JSLint error: “Expected a newline at EOF”, conflict with Beautify plugin, Merge and sum values and put them in an array, How to use a service with Http request in Angular JS, Wordpress log out using URL and redirect to specify page, Javascript sort array of objects in reverse chronological order, Background-image style with JS not working in ie9, Click on link next link should be display on same page, Uncaught error: Invalid type for google table column, Javascript change the souce of all images present inside a string, submitting form then showing loading image by javascript, Onclick add html content and remove it by clicking “delete” link, Get all prices with $ from string into an array in Javascript, Create array from another with specific indices, Javscript Replace Text in tags without changing children element HTML and Content. "); socket.close(); }); ... You can use :contains selector. The iteratee is invoked with four arguments: （ES6のreduceと一緒だが、lodashの方が少し堅牢なのだそう。）, 公式）Reduces collection to a value which is the accumulated result of running each element in collection thru iteratee, where each successive invocation is supplied the return value of the previous. You would be able to write export var test = 'test'; which declares and exports a variable test. Lodash makes JavaScript easier by taking the hassle out of working with arrays, numbers, objects, strings, etc. If fromIndex is negative, it's used as the offset from the end of collection. This method performs a stable sort, that is, it preserves the original sort order of equal elements. Every next interval gets a new time to wait and has to be called again. Let's first define add a mean function to _: Let's define functions for selecting the rows and columns: aggr function takes a sub-list of our data and aggregates its values into one value (which here is a string representation of a rational number): You can control the order or filter the result by specific countryCode or brand by modifying the rows and columns arrays, similar to spreadsheets. ?\d+)/g) || [] That || [] is for no matches: it gives an empty array rather than null. So if you say this: this.listenTo(members, 'change', this.fetch) then fetch will be called like... Javascript is a client-side language. Here, we take “excercise.csv” file of a dataset from seaborn library then formed different groupby data and visualize the result. What is going on with this article? _.keys, _.entries), this is not necessarily the case for their Native equivalent. Any additional arguments are provided to each invoked method. This is document.getElementById("tombolco").style.display = 'block'; Also note that it is getElementById, not with a capital G. Same with 'none',Rest of your code is fine. 値の長さやプロパティの数など、lengthを返してくれる。 You are registering the handler to col-md-1 which is the parent of the delete button, but that element also is created dynamically so when... It’s quite trivial: RegEx string.match(/\$((?:\d|\,)*\. The iteratees are invoked with one argument: (value). 公式）Creates an array of elements split into two groups, the first of which contains elements predicate returns truthy for, the second of which contains elements predicate returns falsey for. setIntervsal() does not fit. * * @param collection * @param retrieveFunctions * @param compareFunctions やっとlodashのCollectionが終わった…！ 公式）Checks if predicate returns truthy for all elements of collection. 公式）This method is like _.flatMap except that it recursively flattens the mapped results up to depth times. Note: Unlike _ _.groupBy(collection, [iteratee=_.identity]) The opposite of _.before ; this method creates a function that invokes func once it's called n or more times. Lodash helps in working with arrays, strings, objects, numbers, etc. Important: Note that, while many Lodash methods are null safe (e.g. 公式）This method is like _.forEach except that it iterates over elements of collection from right to left. １つ目の配列にはtrueの値、２つ目はfalseの値を返す。条件に一致するものとしないものに分別された結果が配列に返ってくる。. 渡した条件によって配列を２つのグループに分ける関数。 GitHub Gist: instantly share code, notes, and snippets. 公式）The opposite of _.filter; this method returns the elements of collection that predicate does not return truthy for. you need to add a new value to the variable, not replcae it. (accumulator, value, index|key, collection). I don't understand why it would give me two hellos back? Since the expression defines one capture group, you get back... A jQuery only way would be to iterate over the nth-child(4n) $('.thumbnail:nth-child(4n)').each(function(){ $(this) .prevAll('.thumbnail').andSelf() .wrapAll($('',{class:"new"})) }); Demo Considering the complexity, not sure whether the prevAll() performs better than the plain for loop. Check your img elements and/or scripts to obtain and set the width and height of the canvas. The order of the grouped values is determined by the order they occur in the collection. 公式）Iterates over elements of collection and invokes iteratee for each element. assign, defaults, defaultsDeep, includes, merge, orderBy, and sortBy. 配列から、[iteratee=_.identity]で渡した条件の結果をkey、条件に当てはまる値の数をvalueに返す。. Iteratee functions may exit iteration early by explicitly returning false. Otherwise, specify an order of "desc" for descending or "asc" for ascending sort order of corresponding values. Many lodash methods are guarded to work as iteratees for methods like _.every, _.filter, _.map, _.mapValues, _.reject, and _.some. multi level group by, lodash, collections. _.groupBy(collection, [iteratee=_.identity], [thisArg]) source npm package Creates an object composed of keys generated from the results of running each element of collection through iteratee. 公式）Creates an object composed of keys generated from the results of running each element of collection thru iteratee. 公式）Checks if predicate returns truthy for any element of collection. _.sortByと使い方は一緒だが、ソート順を昇順・降順決められるところが違う。引数でasc、descを指定してあげる。. Ie: Chart1.series.items[0].format.stroke.fill="red"; ... You can wrap your string into a jQuery-object and use the .find()-method to select the images inside the message-string: var msg = 'hiiiiiii
'; var $msg = $(msg); $msg.find('img').attr('src', 'path_to_img'); $("#chat_content").append($msg); Demo... To get your desired output, this will do the trick: var file = "a|b|c|d, a|b|c|d, a|b|c|d, a|b|c|d, a|b|c|d"; var array = file.split(", ") // Break up the original string on `", "` .map(function(element, index){ var temp = element.split('|'); return [temp[0], temp[1], index + 1]; }); console.log(array); alert(JSON.stringify(array)); The split converts... Let suppose on button click you are calling ajax method before ajax call show image and onComplete ajax method hide this image function LoadData(){ $("#loading-image").show(); $.ajax({ url: yourURL, cache: false, success: function(html){ $("Your div id").append(html); }, complete: function(){ $("#loading-image").hide(); } }); } ... Two issues: There is a typo in your click listener code, javascript is case sensitive, infowindow and infoWindow are different objects, so you are not setting the position of the infowindow correctly. 公式）Checks if predicate returns truthy for inside lib/ and your fixtures inside server/fixtures.js a new value the..., value, index|key, collection ) helps in working with arrays, collection ) the `` ''...
