问题 I'm loading a template with the following data: "slides": [ { "template": "video", "data": { "video": "" } }, { "template": "image", "data": { "image": "" } } ] in my template I want to loop over these slides and based on the configured template I want to load a partial {{#each slides}} {{> resources_templates_overlay_video }} {{/each}} How can I make this partial load dynamically (based on the configured template)? I'm using the require-handlebars-plugin 回答1: As far as I can tell, hbs

问题 I am using Handlebar.js as my templating engine. Now I want to comment out some of the blocks in my handlebar templates. But then I realized that Handlebar doesn't ignore the expressions inside the Handlebar comment block. Any workaround for this? 回答1: The newest version of Handlebars has block comments support : {{!-- {{commented expressions}} --}} https://github.com/wycats/handlebars.js/commit/a927a9b0adc39660f0794b9b210c9db2f7ddecd9 回答2: Just add an exclamation mark after the opening

问题 I'm currently using Handlebars.js (associated with Backbone and jQuery) to make a web app almost totally client side rendered, and I'm having issues with the internationalisation of this app. How can I make this work? Are there any plugins? 回答1: I know this has been answered, but I'd like to share my simple solution. To build on Gazler's solution using I18n.js (which we use with our project at work), I just used a very simple Handlebars helper to facilitate the process to do the localization

问题 I have an array of Ember.Object s which is displayed by Handlebars {{#each}} helper which I want to be sorted by an property of those objects everytime the array changes. So something like this: var arr = [ Ember.Objects.create({ position:0, label:"foo" }), Ember.Objects.create({ position:1, label:"bar" }), ]; And the handlebar {{#each arr}} <div class="label">{{label}}</div> {{/each}} So if I update the positions and the bar object becomes first, I want the view to be updated. Can I depend

问题 I need in Emblem.js to transmit to i18n helper concatenated string constant with variable value, How can i do it? each item in model.items div t "dict.{{item}}" returns error Missing translation for key "dict.{{item}}" 回答1: If you're using Handlebars 1.3+, you can use a subexpression. First, write a string concatenation helper: Ember.Handlebars.helper('concat', function (a, b) { return a + b; }); Then use it like this (sorry, I don't know Emblem so I'm going to use the normal stache syntax):

问题 So I have taken the 'is' helper block from here and modified it so that it register's it's helper through Ember using registerBoundHelper The reason I did that is because I basically need a handlebars based 'switch' statement. The end result in my handlebars is as follows: {{#is MyProperty 1}} ...Do something here... {{/is}} {{#is MyProperty 2}} ...Do something here... {{/is}} {{#is MyProperty 3}} ...Do something here... {{/is}} {{#is MyProperty 4}} ...Do something here... {{/is}} The is

问题 I'm having a similar problem to this one: Setting tagName on application template in ember js While I agree that falling back to a legacy view addon can't be the way to go, here too my bootstrap-based CSS is broken by the enclosing div (the height being not set, to be precise). Now a different way to achieve what I need is to set the enclosing div's classNames property (if it exists), like it can be done with a component: export default Ember.Component.extend({ classNames: ['container'] });

问题 I'm linking a css file to my express-handlebars file but I am getting this error: Refused to apply style from 'http://localhost:4000/cs366/style/draft.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. I have the static directory set, and my css is being applied to home.handlebars, but not fantasyDraft.handlebars My file directory project |-- public | `-- style | |-- home.css | `-- draft.css |-- Fantasy | `-- fantasyRouting

问题 I'm struggling a bit with coming up with a clean, solid way to organize my Backbone application. I'm using Requirejs, Handlebars, and the Requirejs Text plugin to dynamically load HTML views. To simplify things, let's just say the site has the following pages: Home: displays a collection of products About: static page Account: contains account information. products purchased, allows for various updates. Lots of functionality. Has tabs to navigate to different sections. So I'm going for an SPA

问题 I have this template: <template name="sample"> <h1>Sample</h1> </template> Inside a Meteor app I can add this to body this way (as a partial): {{> sample}} It works. I've even tested to call Template.sample(); inside browser console and it works. When I move this inside my package (i.e. a sample.html file inside my package folder) the template seems to disappear: I get Template.sample() is not a function whenever I call the function and I am not even able to render it as a partial. I have a
