underscore.js

问题 Is it possible to somehow take a DOM element from a underscore template and use it as another template? The idea is that my app needs to render a document that contains a loop with items and a summary. I need to occasionaly re-render only the summary or a few items, so I cannot just re-render the whole document. However, I would like to keep it simple for the app users to create their own templates for the document and I think that keeping everything in one file for a document would make it

I have a web page that is part of a ASP.NET web site running on Azure. It's run fine for quite a while now. Out of the blue, I am suddenly having a problem with the browser trying to download a ".map" for Underscore.js. I did some reading and apparently JQuery creates ".map" files as debugging aids for Javascript source files (".js"). However, if I look at

I am trying to accomplish this using lodash/underscore. 回答1: Map every item in the original array to a new array, with a number of items

问题 I'm basically trying to do what is done with this question, but with an array and return all objects using the values of the corresponding array, not just the value: Filter backbone collection by attribute value My natural instinct is to use _.filter or _.partition on the persons collection, but am confused on how these are being compared & returned and am not getting the desired outcome.

问题 I am trying to render an underscore template which is the one below div.col-md-12#english select(value="", class="form-control") option | Select Your Language Preference script(type="text/template" id="english-pref") <% if (selected === "US") { %> option(value="US", selected) | United States <% } else %> <% if(selected === "US"){ %> option(value="UK", selected) | United Kingdom <% } %> Here is my Backbone View code app.NotesView = Backbone.View.extend({ el: '#notes', events: { 'click #save':

问题 I'm using underscore to count object length. _.size(object) . Because this object is being handled by angularjs there's a $$hashKey property in the object that's making the length 1 larger than it should be. What's the correct way to count object lengths in angularjs? 回答1: Will this do? _.size(_.omit(object, '$$hashKey')); Updated angular.copy() strips $$hashKey out for you. So it seems a more Angular way would be _.size(angular.copy(object)); . 回答2: What about _.size(angularObject) - 1; ? If

问题 I've a backbone view that renders a search result in a underscore template. As I want to highlight the search term in the result I have the following print method in the template: print(someKey.replace(searchTerm, '<b>' + searchTerm + '</b>') It works as aspected, but I have to set the searchTerm variable in the global namespace to get this work. I wonder if there is a way to access my views model in the print method, so I could write it like this: print(someKey.replace(searchTerm, '<b>' +

问题 I have HTML template files (underscore template syntax) These files are saved in HTML format so they would be easy to edit (IDE syntax highlight) I don't want to fetch them with ajax, but rather combine them all and include them as a js file. Using GULP as my task-runner, I would like it to somehow combine all the HTML to something like this, as a javascript file that I could include in my BUILD process: template_file_name is the HTML file name. var templates = { template_file_name : '..

问题 I'm using Underscore's template() method in BackboneJS views. I'd like to show a list of alphabet letters in my view in order to sort a collection by letter. As a result, I have a list of 26 links (one link = one letter) in my view. Instead of copy-pasting each link (which is very bad for code maintainability), I was wondering if it was possible to loop through the alphabet via underscoreJS. Result to display : <li ><a href="#">a</a></li> <li ><a href="#">b</a></li> <li ><a href="#">c</a></li

问题 is there a way to pass in an array to grunt.js from the package.json file? I've tried a few different ways and none of them seem to work. I currently have: /*global module:false*/ module.exports = function(grunt) { // Project configuration. grunt.initConfig({ pkg: '<json:package.json>', lint: { files: '<%= pkg.lint.join(", ") %>' } // Default task 'lint qunit concat min' grunt.registerTask('default', 'lint'); }; package.json { "lint": [ "grunt.js", "test.js" ] } The only solution that I have
