handlebars.js

问题 I am trying to incorporate this working example http://jsbin.com/AViZATE/37/edit of a filtering search bar with my own project. The search bar does not seem to be connected to my list of objects. :( Let me show you what I've done. App.RecordCategoriesController = Ember.ArrayController.extend({ searchResult: function(){ var searchTerm = this.get('searchTerm'); var regExp = new RegExp(searchTerm,'i'); this.get('model').set('content',this.store.filter('recordCategory',function(item){ return

问题 I am using PHP-backend, Backbone.js and Handlebars.js. My javascript requests for data, and JSON data is returned successfully (json_encode). When I give this JSON data to the handlebars template, it is not displaying. I realised the square brackets in front and at the back of my JSON object are 'disliked' by Handlebars.js and not being displayed. Take a look at the code below. var ArticleListView = Backbone.View.extend( { el: $('#main'), render: function() { var template = Handlebars.compile

问题 I've an ember property which includes html tags ( <br /> , <strong> , <p> , <span> , and similar stuff). How can i tell ember not to escape this text? Is there any default Handlebars helper from ember, or need I to write my own? 回答1: From http://handlebarsjs.com/ Handlebars HTML-escapes values returned by a {{expression}} . If you don't want Handlebars to escape a value, use the "triple-stash". {{{expression}}} 回答2: Within Ember.js you can do this via the htmlSafe method, which is added to

问题 I use handlebars, and if an escaped character such as ' is processed it is rendered on screen as ' . I know wrapping the variable in a triple-stash will prevent this. I processed the following string within a triple-stash as a quick test and it seemed fine " <p>hello<p> wouldn't wouldn ' t" This rendered to screen exactly how I wanted it to. My question is, is it safe to simply wrap all variables in triple-stash? or will this have some unforeseen consequences I haven't considered? Thanks 回答1:

问题 According to my testing, Facebook's crawlers do not render client-side templates like a browser. I want to avoid a webserver and building HTML files for Open Graph objects at all costs. I want to generate the meta tags on the fly via the URL, but it seems Facebook cannot do this. Can someone from Facebook please confirm? I asked the head of Open Graph at #mobiledevcon and she said that Facebook can render stuff like {{value}} My meta tags are as follows, and they render fine in every browser.

问题 In my Meteor app I find myself writing a lot of things like: Templates.myTemplate1.isCurrentUser = function() { return Session.get("isCurrentUser"); }; Templates.myTemplate2.isCurrentUser = function() { return Session.get("isCurrentUser"); }; I need many different templates (I'm using handlebars) to access the same simple value stored inside Session. Is there a way to avoid writing the same function over and over again? Thanks 回答1: As meteor is currently using handlebars as default templating

问题 I am new in pretty ember js development . I have done view below code {{view "select" content=model prompt="Please select a name" selectionBinding="" optionValuePath="content.body" optionLabelPath="content.title"}} using following Json posts = [{ title: "Raja", body: "There are lots of à la carte software environments in this world." }, { title: "Broken Promises", body: "James Coglan wrote a lengthy article about Promises in node.js." }]; and Router App.InRoute = Ember.Route.extend({ model:

问题 I have an issue with Ember.Select views taking really long to render. Ember Inspector gives me rendering times of around 20-30ms for vanilla built in Ember.Select views (http://emberjs.com/guides/views/built-in-views/). That's fine with one or two Select fields but really adds up when you go beyond a few of them... Here is an example of a basic Select JS Bin: http://jsbin.com/xawak/10/. Are there any best practises to get around this? 回答1: Its an issue of the ember JS select component which

问题 I'm using Handlebars in my NodeJS application as my templating engine. I've put all my templates in a views folder like so : - - /controllers - /views - index.html - server.js Here's my code to render the template when the user access a given URL (using express for routing) : app.get("/", function(req, res){ var template = handlebars.compile("views/index.html"); var data = {"name": "Charles"}; var result = template(data); res.send(result); }); I'm trying to render a template from a file, but

问题 Trying to print out all combinations of 2 items from an array. var source = document.getElementById("entry-template").innerHTML; var template = Handlebars.compile(source); var context = { colors: ['red', 'blue', 'green'] }; var html = template(context); document.getElementById("output").innerHTML = html; <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.11/handlebars.js"></script> <script id="entry-template" type="text/x-handlebars-template"> output: {{#colors}} {{#..
