handlebars.js

问题 I have a single Workouts collection, each object having a category and a name . At the HTML layer, I'm creating a category header, then displaying a list of workouts beneath. I have it working, but there's no way I'm doing it the meteor and/or handlebars way. Think I'm struggling with understanding the context of this , as well as how to pass data into a template. Here are my template functions: Template.categories.getCategories = -> workouts = Workouts.find().fetch() categories = _.map

问题 I am using ember to built a "wizard accordion" . Basically what I want is: an accordion which is always shown the accordion contains all the steps one step is active but it is also possibly to change the header of previous steps each step has its own model (e.g. Selecting from countries in first step, selecting from products in second) it should be possible to jump back and force between steps out of all the selections a central model is built which is sent to the server after the final step

问题 Is it possible to within a Handlebars.js helper to create elements using jQuery and attach event handler to them? I'd like to be able to create active elements using helpers. Example: Handlebars.registerHelper("button", function(title) { var button = $('<button>').text(title); button.click(function() { alert("Button " + title + " clicked."); }); return $('<div>').append(button).html(); }); In the handlebars template I instantiate the button like this: {{{button "Click Me!"}}} I understand

问题 In my Handlebars template I check for the existence of a variable, and render some text if it's there: {{#if foo}} some text {{/if}} This works fine if foo is text or if foo is numeric but not zero. But if var foo = 0; then {{#if foo}} returns false. This appears to be yet another Javascript oddity, because Javascript itself behaves the same way. In Javascript code, though, you could get around this by checking if the variable is 'undefined'. How can I do the same thing in Handlebars? I could

问题 I am developing a bigcommerce stencil theme. I want to use basic handlebars functionality like markup <div id="mobile"></div> <script id="mobile_category_template" type="text/x-handlebars-template"> <div class="entry"> <h1>{{var}}</h1> <div class="body"> <p>body</p> </div> </div> </script> <script src="{{cdn 'https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.10/handlebars.min.js'}}"></script> <script src="{{cdn '/assets/js/category.js'}}"></script> javascript var hitTemplate =

问题 First, I dumped the output that's going to the Handlebars template and ran it through JSONlint.com and it validates, so my inputs are valid. Second, this is the best example code I could cook up that's representative but doesn't include vital data: http://codepen.io/Muzical84/pen/BNBLom?editors=101 (note, if you have HTTPS-Everywhere on, turn it off on codepen.io since the support is listed as "partial," and Chrome might still bark about unsafe scripts; I included all of the libraries besides

问题 I want to use ember properties to toggle the visibility of a div by calling it's dynamic id, however even though I can do something similar by calling classes, I cannot do the same for id's. For example: {{bind-attr class=":class1 controller.controllerProperty:class2"}} works fine. I can toggle the controllerProperty from an action in my controller. You would think the same concept would apply to id's. However {{bind-attr id=":staticId controllerProperty:id{{dynamicIdNumber}}"}} makes the id

问题 I'm actually doing this in a JSON object but for this question, I will simplify. I can't seem to get my Handlebars template to build correctly. Here is a sample array of objects that I am passing: var data = { DocumentInfo: [ { Category: "General", DocumentList: [ { DocumentName: "Document Name 1 - General", DocumentLocation: "Document Location 1 - General" }, { DocumentName: "Document Name 2 - General", DocumentLocation: "Document Location 2 - General" } ] }, { Category: "Unit Documents",

问题 In a handlebars template, can I access a handlebar parameter inside a script tag like <script> var aList = {{list}} </script> The template is called from express with response.render('template', {list: [1, 2, 3]}) 回答1: You can use a hidden input in your html that contains the value you want and then get that using document.getElementById in the script tag. <input type = "hidden" id = "thingIWant" value = {{list}} /> <script> var aList = document.getElementById("thingIWant").value; </script>

问题 Right now I have this json structure "administration" : [ { "name" : "Sigfried Bermudez", "role" : "Associate Director" }, { "name" : "Karen Madrigal", "role" : "QA Manager" }, { "name" : "Jorge Lopez", "role" : "Project Manager" } ] as you see the last element in that array says "role" : "Project Manager" , and the way I am excluding this element from the view is this {{#each chart-container.[3].administration}} {{#unless @last}} <span>{{@key}} {{this.name}}</span> {{/unless}} {{/each}} but
