问题 The Ember guide on binding data attributes says that "If you use data binding with a Boolean value, it will add or remove the specified attribute." I'm trying to use this feature to dynamically set the selected attributes on <option> s. I'm finding that I can dynamically set the disabled attribute, but the selected attribute is always omitted, no whether the boolean is true or false. Given this handlebars template: <option disabled={{false}} selected={{false}}>One</option> <option disabled={

问题 Is there an easy way to load a partial, with multiple templates in it, using handlebars.js, just like you can do it using mustache.js and the jQuery plugin from "jonnyreeves" e.g: $.Mustache.load('./templates/greetings.htm').done(function () { $('body').mustache('simple-hello', viewData); }); 回答1: In Handlebars.js you need to register each partial, using Handlebars.registerPartial You can do it like this: Javascript $(document).ready(function() { //Get template from server $.get("http:/

问题 I'm trying to bind my data model to the text field in Ember.js. The model has a field that represents a currency value (e.g., $1,000.50). The user can then change this value. Ember receives the data as a Number (1000.50) -not currency formatted. I bind the view to a computed property that has the nice format. Here is my Handlebars template. {{input classNames="amount" valueBinding="p.amountFmt"}}</td> My model looks like: App.Product = Ember.Object.extend({ amount : 0.00, amountFmt: function

问题 I am using Handlebars (v 1.0.0) to fill a table in HTML. However somehow it does not fill the table like I am used to. Here is my template: {{#if users}} <table> {{#each users}} <tr> <td>{{username}}</td> <td>{{email}}</td> </tr> {{/each}} </table> {{else}} <h3>No users found!</h3> {{/if}} So I does find users because I do not see the "No users found!" and when I call an empty object it does show the "No users found!". When I do not use the table and print out these users like the next

问题 Using Backbone.js, Handlebars and Require.js with i18n. I have my en_us.js file with all the string translations, but how do I deal with the case of dynamic values being sent to the template? I know all these strings ahead of time, but hard coding them into the template seems messy, can I pass in a pre-translated string some how? I am using the hbs module for the i18n and templates with require.js. 回答1: I see this problem not related to i18n but to any case where you need render data that

问题 Using the already-overused to-do app example, let's say I want an element with a "todo" class (static) and an "is-done" class (dynamic): <div {{bindAttr class="todo isDone"}}> Other stuff in here </div> In this case, "isDone" and "todo" are both expected to be properties on my view object, which is what I want for "isDone", but not for "todo". I'm currently working around this by adding a "todo" property on my view that is equal to a static "todo" string. Is there any way to have a static

问题 I know its been asked many times, I have looked at the answers and not sure where I am going wrong.

问题 How do I pass data between two different routes and templates? I have a javascript file on the front end (client folder) that simply calls Router.go() passing in the post ID as one of my parameters. Below are the three main culprits (I believe). I've removed most of the code to make it easier to read. I can change to the PostDetail page with no problems. I can also retrieve the PostId on the PostDetail page from the Router. My problem is, the database entry ( POLL ) that is retrieved does not
