问题 I was wondering if its possible to do something like this: {{#if ClientController.Client.number && PhoneController.hasLinesToInstall}} ... {{/if}}} Thanks, Juanitos 回答1: I don't think it's possible to chain conditions like that in handlebars like that - I can't find anything about it in the documentation. You could nest them though, like this: {{#if ClientController.Client.number}} {{#if PhoneController.hasLinesToInstall}} ... {{/if}} {{/if}} That would achieve the same outcome. 回答2: It's not

Using HTML anchors in Ember.js

由 ￡可爱￡侵袭症＋ 提交于 2019-12-07 03:27:01
问题 In my Ember application, how can I jump to an HTML anchor inside one of my Handlebars templates? I created a jsFiddle that shows what I want to accomplish. Background Ember's model of navigation through an application uses HTML anchors. I have the following requirement: when a user clicks on a Handlebar linkTo helper to navigate to a new route destination , the browser should automatically scroll to an anchor inside the Handlebars template associated to that new route destination . 回答1: Use

问题 I am trying to use query-params in my route / controller but the handlebars helper is causing this error: Uncaught Error: <(subclass of Ember._MetamorphView):ember689> Handlebars error: Could not find property 'query-params' on object . This error is caused by this link to helper: {{#link-to 'betround.stats' (query-params game=id) }} <li {{bind-attr class="isPast:small"}}> {{team1}} {{scoreT1}} : {{scoreT2}} {{team2}} (gameid: {{id}})</li> {{/link-to }} I have already upgraded Ember and

How can I specify an alternative directory for my HandlebarsJS templates with the ember-rails gem?

问题 I have a Rails application, and I'm using Ember on the front-end. I'd like to move the ember-related files down one level in the directory structure, but when I do, the templates no longer render. In the plain, vanilla, working version of the application, my directory structure is: ./app/ assets/ javascripts application.js ember-app.js routes.js store.js models/ controllers/ routes/ templates/ views/ with: application.js //= require jquery //= require jquery_ujs //= require handlebars //=

Why should we wrap our templates inside script blocks?

由 痞子三分冷 提交于 2019-12-07 01:26:16
问题 Background All the JS template engines recommend putting your template text inside script blocks like so: <script id="peopleTemplate" type="text/template"> {#people} <div class="person">Name: {firstName} {lastName}</div> {/people} </script> but many developers (understandably) dislike this because they lose HTML syntax highlighting in their code editor inside the script block. I've seen the workarounds like this: Keep correct HTML syntax highlighting in <script> "text/html" templates . This

Handlebars templates using ampersand and caret

由 主宰稳场 提交于 2019-12-07 00:55:34
问题 We found some old Handlebars templates which are working fine, but include some odd usage of Handlebars. The two strange ones are {{^is_question}}{{/is_question}} and {{& answer}} Neither of those are listed in the Handlerbars docs and there are no helpers defined. Anyone know what they do? The ^is_question appears to be used interchangeably with {{#if is_question}}. Maybe it is some deprecated shorthand notation? The template is compiled the same way we compile other templates: template =

问题 I'm trying to create a table that populates each table cell with an object from a JSON file. My handlebars template just adds a with the data for each object. What I'm trying accomplish is for every 5th item a new row is created and then it continues populating out the table cells until the 10th item then it creates a new row etc. I've been reading up on @index. Is there some function that does something like {{#if @index / 5 == 0}} ? Otherwise is there something handlebars offers that could

Accessing handlebars variable inside client js file

由 点点圈 提交于 2019-12-06 20:50:30
I'm generating a handlebars view with hbs for express js framework, and I need to access the variables I pass to the view from inside a separate JavaScript file. For example: var foo = {{user.name}} Obviously this code throws an error, but what is the preferred way of getting hbs variables inside JavaScript? Currently I'm running another ajax request to get the same data. but I think it is not wise to make another request for the same data... Found the solution, seems like i just had to put the handlebars variable inside a string for it to work. In order to pass and Object to a variable I

问题 How can I access to an array element inside handlebars template using a variable instead of an hardcoded value? I need to do something like: {{#each condition in conditions}} {{App.ops.[condition.op].name}} {{/each}} at the moment doesn't give me a parse error but on runtime doesn't return me nothing.
