handlebars.js

问题 I'm working on a node / express / handlebars app and I just found out about custom helpers, but I have no idea where to define them. I tried adding some in the actual view template hbs file in a <script> tag like so: <script type="text/javascript"> Handlebars.registerHelper('if', function(conditional, options) { console.log("IN HANDLEBARS HELPER"); if (conditional) { return options.fn(this); } else { return options.inverse(this); } }); </script> But I get a Uncaught ReferenceError: Handlebars

问题 I'm working on a project with Meteor. I've tried loading javascript files using script tags but of course that won't work. These same files I've tried loading using script tags, I've also just saved as files and placed them in the lib folder so they could be loaded last. There is also an internal script that has issues loading. I even tried removing the (function(){ part and closing part of the function because I know it'll already be placed into a function with Meteor. How can I get the code

问题 So referring to the original problem I have here Google Maps Javascript V3 Uncaught TypeError: Cannot read property 'offsetWidth' of null and after doing a lot of googling, I have found a solution which I thought would be workable which is this How to append multiple Google Maps areas to divs using Handlebars. However, I have implemented mine in the following way var EmployeeView = function(employee){ this.render = function(){ $('body').append(this.el); // inside the new div, put the

问题 I know that http://builds.emberjs.com/ has Ember Latest Stable Ember Data Latest But where can I find the latest compatible handlebars source URL? http://emberjs.com.s3.amazonaws.com/getting-started/handlebars.js is version 2 but the latest Ember requires version 3. 回答1: You were almost there. You can find the latest compatible handlebars.js directly here: http://builds.emberjs.com/handlebars-1.0.0.js So this leaves you with: http://builds.emberjs.com/handlebars-1.0.0.js http://builds.emberjs

问题 Is there any way to pass a variable context to the {{render}} helper? For instance, I have a polymorphic relationship on my model, and I want to render the appropriate view for each different type (without have to write a whole string of if statements. my events template looks like this: <ul> {{#each event in model}} <li> {{event.time}} {{render event.type event.eventable}} </li> {{/each}} </ul> the event.type is a string and is set to song . If I use {{render 'song' event.eventable}}

问题 TL;DR In the following Handlebars template... <div class="field field-label"> <label>{{label}}</label><input type="text" value="{{{{attribute}}}}"> </div> I need {{attribute}} to be evaluated but value="{{ value of attribute }}" to be printed. Background I've got an interesting use for templating. My application has dozens of forms (and growing!), and several ways to display them. Obviously they can be displayed in the browser, or a mobile device, or a PDF, etc... So what I'd like to do is

问题 I have a modal that makes new tags with ajax. It does a POST method with the Tags parameters without recharging the view. So I want, depending on the "price_type" parameter chosen, to render one price div or another. Im using Handlebars so I suppose this is not ruby's conditional responsability (because of AJAX), but Handlebars conditionals responsability. The problem is I tried plenty of ways of making Handlebars conditionals with no success. I want to achieve the equivalent of this with

问题 I am fairly new to Ember (using version 0.2.3). I have a component with a few computed values. They gather these computed values from input fields: export default Component.extend({ loanAmount : 200000, deductible : 0, debtInt : 5, getLoanCosts: computed('loanAmount', 'debtInt', function(){ return (get(this, 'debtInt')/12) * get(this, 'loanAmount'); }) On my template.hbs, I have an input field {{ input value=loanAmount }} and I can call {{getLoanCosts}} in my template.hbs, to show the

问题 I know this is somewhat duplicated, but All my efforts to create a dynamic component renderer are failing possibly due to my lack of knowledge in ember concepts. My Scenario is a multi purpose search bar which will search for models in the cache. I would like each search result to be rendered below the search input according to the model's type key. the handlebars file will be named according to the model type with the syntax components/app-search-<model-type-key>.hbs e.g. the template name

问题 I'm building a simple webapp with just Handlebars.js and some jQuery. Now I have a list of data, and i present them through a Handlebars-template. Then I want some actions associated with these, e.g. update one element, or delete one. I have buttons that one associates with these actions, the problem is that I cannot manage to get onclick -methods associated with buttons in the template to work. I read this question and answer, which lead me to adding the extra bracket and helpermethod, but
