handlebars.js

问题 I have the following handlebars template (fragment): {{#each cbe in abs.XyzBookingEntries}} <tr> {{#if cbe.isLoaded}} <td>{{cbe.XYZdata.ApptDuration}} min:</td> <td> {{cbe.XYZdata.ApptType}} {{#if cbe.XYZdata.ApptTypeDetailCode}} ({{cbe.XYZdata.ApptTypeDetailCode}}) {{/if}} </td> <td {{bindAttr class="cbe.XYZdata.statusClass"}}><strong>{{cbe.XYZdata.ApptStatus}}</strong></td> {{else}} <td> Loading... </td> {{/if}} </tr> {{/each}} From which you can observe two things: I have capitalized

问题 Is it possible to create a Handlebars Helper Function that returns async result? Maybe Handlebars supports some kind of two way binding? I want to use JSON data from JSONP request so jQuery.ajax also does not support async: false, but however this would not be exactly the same that I am looking for. 回答1: You can call whatever functions you want in a helper but that won't do you any good. The problem is that Handlebars helpers work with strings and someone else will convert those strings to

问题 I'm trying to make a reactive menu using meteor session (to persist the view the user was).. but it is not working, the Session.get('currentView') get changed (teste in chrome console), but the page don't render again. .html <div class="col-1-1 menu" style="height: 42px;"> <ul> <li><a class="dashButton" href="#"># Dashboard</a></li> <li><a class="myJobsButton"href="#">Jobs</a></li> <li><a class="helpPageButton"href="#">Help</a></li> </ul> <br style="clear:left"/> </div> {{#if currentViewIs

问题 I know that Javascript object keys are not 'ordered' so by definition cannot be sorted – however I would like to output them in alphabetical order using Handlebars for display purposes. The part of the object I'm interested in looks like this: { "A publisher" : { journals : { "A journal" : {}, "B journal" : {}, "C journal" : {} } } "B publisher" : { journals : { "D journal" : {}, "E journal" : {}, "F journal" : {} } } } I'd like to be able to template the object using Handlebars ordered

问题 I'm developing a web application and I'd need some advice on how to solve the following 'problem' of internationalization. I use Grails 2.2.0 along with Ember.js and Handlebars.js whereas the frontend (which is realised through JavaScript with the before mentioned frameworks) is residing in it's on project with the Sass files for styling Grunt.js for compiling the whole thing. Within this 'frontend project' I create the handlebars templates which I want to deliver via Grails on demand, with

问题 I'm upgrading to Ember rc5 from rc3, but I'm getting the following error: Uncaught Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 1.0.0-rc.4) or downgrade your runtime to an older version (== 1.0.0-rc.3) Here are the relevant lines in my gemfile, taken straight from the ember-rails README (except pulling the gem from git... it gives the same error whether I include that or not) gem 'ember-rails', git

问题 EDIT: This is no longer relevant in Meteor 1.0. The first syntax has been deprecated, and only the second is supported. It seems that there are two ways to define what are apparently called helpers in Meteor: Template.foo.helper1 = function() { ... } Other way: Template.foo.helpers({ helper2: function() { ... } }); Is there any semantic or usage difference between the two? The only restriction I can see is that the first usage can't use reserved keywords. I'm wondering if the distinction

问题 I have the following simplified document: { channel:'Channelname', users: [ {userId:1}, {userId:2}, {userId:3} ] } How can i access the userId's in a {{#each}} loop like so: {{#each channels}} {{channel}} {{#each channels.users}} {{userId}} //or {{channels.users.userId}} ? {{/each}} {{/each}} The first {{#each}} loop prints my channelname as expected, but the second {{#each}} loop doesn't print anything. Regards, Cid 回答1: Use {{#each channels}} {{channel}} {{#each users}} {{userId}} {{/each}}

问题 Using: ember: v1.0.0-pre.4 ember-data: revision 11 handlebars: 1.0.rc2 So I have a template that I've hooked up to a controller that's receiving info from an REST API. In just print out text, this is fine but these handlebar expression... <img src="{{ imageUrl }}"/> ...when inserted into the dom look like: <img src="<script id='metamorph-28-start' type='text/x-placeholder'></script>http://asdf.com/image.jpg<script id='metamorph-28-end' type='text/x-placeholder'></script>"> I'm obviously very

问题 I would like to set a randomly generated background image. I am using Meteor and am calling Flickr API to provide a random image URL which I would like to set as my background image. From what I've read, it seems that CSS is now the recommended way to set a background image. Is there a way to inject the dynamically generated url into the CSS? I can't seem to find examples showing mixing of Handlebars.js and CSS - is this possible? Or should I be avoiding CSS and setting the background image
