handlebars.js

问题 I have my data in the collection and I need to render them into the template. How can I achieve the result when the data is grouped by two? I need to sort them like this: ._______________________ | 1 | 3 | 5 |___|___|_______________ | 2 | 4 | and so on... |___|___|_______________ I have created vertical div element for each 1+2, 3+4, ... pair to style the items like this. How can I render the data in to such grid with handlebars? All I can do is this: {{#each App.myController}} ... render

问题 I have a handlebars/mustache layout file in my node.js application that looks like this: {{> header}} {{> navbar}} {{{body}}} {{> footer-user}} {{> footer}} Since all five lines are includes, is there any difference between the two types of includes? Could I replace {{{body}}} with {{>body}} or {{> header}} with {{{header}}}? They both appear not to escape the html that gets included. What's the best practice? 回答1: The syntax {{> name}} is for partials, i.e. to include another template:

问题 I just started playing with express.js using handlebars.js as my template I wanted to create a delete link, which should be restful and use http verb DELETE instead of GET. I finally figured out a way to achieve it by creating a link like so below, adding data-method of delete, and then using jquery on client side to intercept my link to use DELETE verb. My link was: <a href="/destroy/{{_id}}" data-method="delete">delete</a> <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1

I just need to put one variable in label's "for": <label for='{{queue.id}}'> Instead <label for="6"> i get <label for="<script id=" metamorph-51-start'="" type="text/x-placeholder">6<script id="metamorph-51-end" type="text/x-placeholder"></script>'><script id="metamorph-52-start" type="text/x-placeholder"></script>Очередь через личный кабинет<script id="metamorph-52-end" type="text/x-placeholder"></script></label> If i simply use {{queue.id}}

问题 I'm loading this Handlebars.js template: <ul></ul> with AJAX using the following code $.ajax({ url : 'collection.handlebars', success : function (data) { Handlebars.templates["collection"] = Handlebars.compile(data); }, async : false }); The template compilation fails with the following message in the browser console: Uncaught Error: You must pass a string to Handlebars.compile. You passed [object Document] After debugging I noticed that the data returned in the success callback is an HTML

问题 I'm using Mandrill's send-template API method to send an email. It shouldn't matter, but just in case, I'm using PHP. The email is delivered using the correct template, but none of the Handlebars variables are replaced with their values. Instead, they're merely removed. Here's a full request as seen in the API Logs after reducing my code: { "template_name": "my-template-slug", "template_content": [ { "name": "price", "content": "$25" } ], "message": { "subject": "My Subject", "from_email":

问题 I just stumbled over emberJS and thought it would be worth trying it out for my next web application. What I actually plan to do is showing a list of objects in a 2-dimensional way (atm this can be a table). What I have so far: <script type="text/x-handlebars"> <table width="100%" style="text-align:left"> <tr> <th> </th> {{#each App.MyController.getColumnValues}} <th>{{this}}</th> {{/each}} </tr> {{#each App.MyController.getRowValues}} <tr> <th>{{this}}</th> {{#each App.MyController

问题 i have an ember view with a bunch of jquery code to manipulate the dom, the thing is when i use: this.transitionTo("forecast.workpage", id); it only loads the view once but when i try click it again the view doesn't execute again, i try several ways for instance adding this.rerender() in the end of my didInsertElement like that: didInsertElement : function(){ //all my js code this.rerender() } but it trows an error Uncaught TypeError: Cannot read property '0' of undefined , try adding this.

问题 I was wondering if there is a way to simplify this handlebars template to not use a helper. Data: { games:[game: {teamID:1}] teams:{1:{name:'Team Name'}} } Template (note that is is within a {{#each games}} : {{#teamFetch ../this teamID 'name'}}{{/teamFetch}} Helper: Handlebars.registerHelper('teamFetch', function(season, teamid, property){ return season.teams[teamid][property]; }); I'm new to handlebars but this was the only way I could figure out how to access a specific team in the season

问题 I'm trying to create a Handlebars.registerHelper() that would wrap my {{>template}} in an {{each items}} for every number I enter. So something like this; {{forevery items 4}} {{> item_row_template}} {{/forevery}} The desired result would be for every 4 items wrap it around a div. <div class="row"> <div class="item_1">item</div> <div class="item_2">item</div> <div class="item_3">item</div> <div class="item_4">item</div> </div> <div class="row"> <div class="item_1">item</div> <div class="item
