handlebars - is it possible to access parent context in a partial?

阅读更多关于 handlebars - is it possible to access parent context in a partial?

问题 I've got a handlebar template that loads a partial for a sub-element. I would need to access a variable from the parent context in the calling template, from within the partial. .. doesn't seem to resolve to anything inside the partial. Simplified code goes like this: the template {{#each items}} {{> item-template}} {{/each}} the partial value is {{value}} (obviously the real code is more complicated but it's the same principle, within the partial .. appears to be undefined.) To show it's

What's the use of Jade or Handlebars when writing AngularJs apps

阅读更多关于 What's the use of Jade or Handlebars when writing AngularJs apps

问题 I am new(ish) to the whole javascript full stack applications, and completely new to Angular, so I was hoping somebody can put the record straight for me here. Why would I need to use a templating framework like Jade or Handlebars when writing client side apps using AngularJS. I should say that I have never used any of these templating frameworks either. So I am not familiar with the advantages completely. But when I look at Handlebars for example, it does many of the same things as I would

Retrieving HTML from MongoDB for use in Template

阅读更多关于 Retrieving HTML from MongoDB for use in Template

问题 I'm new to Meteor.js and MongoDB so this question might have an obvious solution that I am missing but so far my searches have turned up nothing. My first Meteor project is a very bare-bones blog. In the MongoDB I have the following: Blog.insert({ author: "Name Here", title: "Title Here", headerHTML: "This is my <b>very</b> first blog post.", bodyHTML: "What drives us to <em>solve</em> these types of problems?", date: new Date() }); Then in blog.js I have: if (Meteor.isClient) { Meteor

Iterating over a model's attributes in EmberJS handlebars template

阅读更多关于 Iterating over a model's attributes in EmberJS handlebars template

问题 Is there a way to iterate over a view's context's attributes in EmberJS? I am using Ember-Data (https://github.com/emberjs/data) for ORM. Lets say I use connectOutlets to register a UserView with a user that has attributes such as email, name, etc. In the connected Handlebars template, is there anyway that I can iterate over those attributes? I basically need to build a generic view that can be reused with different models... 回答1: Ryan is right about the attributes, but it takes some doing to

How to get index in Handlebars each helper?

阅读更多关于 How to get index in Handlebars each helper?

I'm using Handlebars for templating in my project.

Express.js hbs module - register partials from .hbs file

阅读更多关于 Express.js hbs module - register partials from .hbs file

问题 I'm using the handlebars.js hbs wrapper in express.js. I have templates working fine, but I'm needing to add in partials to be rendered with my views. I'd like to do something like this: hbs.registerPartial('headPartial', 'header'); // where "header" is an .hbs file in my views folder However, it's throwing a "header partial can not be found". I can make the registerPartial work if I pass a string of html to the second param, but I'd like to use separate view files for my partials. I haven't

Handlebars.js parse object instead of [Object object]

阅读更多关于 Handlebars.js parse object instead of [Object object]

I'm using Handlebars templates and JSON data is already represented in [Object object], how do I parse this data outside of the Handlebars? For example, I'm trying to populate a JavaScript variable on the page through a handlebars tag, but this doesn't work. Any suggestions? Thank you! EDIT: To clarify, I'm using ExpressJS w/ Handlebars for templating. In my route, I have this: var user = {} user = {'id' : 123, 'name' : 'First Name'} res.render('index', {user : user}); Then in my index.hbs template, I now have a {{user}} object. I can use {{#each}} to iterate through the object just fine.

问题 I'm using Handlebars.js for client side view rendering. If Else works great but I've encountered a 3 way conditional that requires ELSE IF: This doesn't work: {{#if FriendStatus.IsFriend }} <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div> {{else if FriendStatus.FriendRequested}} <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div> {{else}} <div class=

Handlebars Template rendering template as text

阅读更多关于 Handlebars Template rendering template as text

问题 I created a helper in Handlebars to help with logic, but my template parses the returned html as text rather than html. I have a quiz results page that is rendered after the quiz is completed: <script id="quiz-result" type="text/x-handlebars-template"> {{#each rounds}} {{round_end_result}} {{/each}} <div class="clear"></div> </script> For each of the rounds, I use a helper to determine which template to render a round's result: Handlebars.registerHelper("round_end_result", function() { if
