核能气质少年 提交于 2019-12-04 00:14:30
I am using Jekyll for our blog and rendering Handlebars templates is a pain. We have to escape like so: {% highlight html %} <div>{{"{{code"}}}}</div> {% endhighlight %} It's fugly. Is there an easier way to do this? I found the answer: {% highlight html %} {% raw %} <div>{{code}}</div> {% endraw %} {% endhighlight %} 来源: https://stackoverflow.com/questions/14209942/how-to-render-handlebars-markup-from-a-liquid-template-jekyll

Handlebars does not fill table

痞子三分冷 提交于 2019-12-03 23:18:19
I am using Handlebars (v 1.0.0) to fill a table in HTML. However somehow it does not fill the table like I am used to. Here is my template: {{#if users}} <table> {{#each users}} <tr> <td>{{username}}</td> <td>{{email}}</td> </tr> {{/each}} </table> {{else}} <h3>No users found!</h3> {{/if}} So I does find users because I do not see the "No users found!" and when I call an empty object it does show the "No users found!". When I do not use the table and print out these users like the next example. The usersnames and mail address' will show up in my HTML. {{#if users}} {{#each users}} {{username}}

Handlebars.js - Access object value with a variable key

巧了我就是萌 提交于 2019-12-03 22:31:25
Looking for a way to access to achieve this: {{#each someArray}} {{../otherObject.[this]}} {{/each}} How do I evaluate the value of this and then reference it as a key to my object otherObject ? With lookup: http://handlebarsjs.com/builtin_helpers.html#lookup {{#each someArray}} {{lookup ../otherObject this}} {{/each}} One possible solution with a helper: /* {{#each someArrayOfKeys}} {{#withItem ../otherObject key=this}} {{this}} {{/withItem}} {{/each}} */ Handlebars.registerHelper('withItem', function(object, options) { return options.fn(object[options.hash.key]); }); 来源: https:/

how to have grunt task render mustache partials to static HTML

那年仲夏 提交于 2019-12-03 20:35:17
Background I've been using grunt.js with a hogan.js task to build the static HTML for our internal docs. I'm learning JavaScript as I go, but I've gotten the task to work well enough for layouts and pages, but it would really help our workflow to have the hogan task render mustache partials to HTML, as in the example in this gist: https://gist.github.com/4132781 Current Setup and what I want to accomplish All of our mustache partials are in a folder called "partials". Ideally when the grunt build is run, the hogan task will grab any partials from the partials folder and insert them into the

What's the difference between Handlebars helpers and Ember Handlebars helpers?

丶灬走出姿态 提交于 2019-12-03 19:56:25
问题 I can't catch up with all those changes done to plain Handlebars and modified Ember Handlebars helpers. If I remember correctly you can register a helper with the following methods Ember.Handlebars.helper Ember.Handlebars.registerHelper Ember.Handlebars.registerBoundHelper Handlebars.registerHelper That's too much for me. Could you explain it down to earth what's the difference? 回答1: Ember.Handlebars.registerHelper is a basic helper that does not bind the argument string to a property. For

问题 I am learning Backbone/Handlebars/Require. I have looked all over online and on SO - are there any tutorials or websites that you can direct me to that would provide helpful information for using using handlebars instead of underscore? 回答1: Using handlebars.js instead of underscore templating is pretty straightforward. Check out this example: https://cdnjs.com/libraries/backbone.js/tutorials/what-is-a-view (scroll to the "Loading a Template" section) SearchView = Backbone.View.extend({

Format a date from inside a Handlebars Template in Meteor

眉间皱痕 提交于 2019-12-03 17:54:00
问题 I got a ISO formatted Date from my Data and what I actually want to do, is to modify my date format directly from my Templates. like this: {{format my.context.date "myFormat"}} I'm using the moment library, so I could write something like this: {{formatDate my.context.date "DD.MM.YYYY HH:mm"}} // 03.09.2013 18:12 It would be nice, because I think it's the place where I should be able to do this. In my template. 回答1: The solution is quite simple, and maybe someone will find it useful. In most

Handlebars.js: Use a partial like it was a normal, full template

一曲冷凌霜 提交于 2019-12-03 16:29:00
问题 I have a template that I want to use both as a partial, and by itself from javascript. 回答1: If your templates are precompiled, you can access your partials via Handlebars.partials['partial-name']() as well as call them from a template via the {{> partial}} helper. This is nice because you can then write a utility function for rendering a template whether it be a full blown template or partial. ex: function elementFromTemplate(template, context) { context = context || {}; var temp = document

Handlebars doesn't render boolean variables when false

这一生的挚爱 提交于 2019-12-03 16:03:08
问题 Handlebars.js has some weird behavior. It renders a boolean with a value of true as the string "true", but a value of false as "". var booleanTestTrue = true; var booleanTestFalse = false; Template: True: {{booleanTestTrue}} False: {{booleanTestFalse}} Renders to: True: true False: (empty string) Is there any way to fix this problem? Or do I have to write a helper? 回答1: You can use a simple block helper and implement #if like the following: {{#if isTrue}} true {{else}} false {{/if}} 回答2: If
