问题 I have the following issue: When rendering a view in a layout with handlebars, the engine adds an extra text node before the rendered view body <nav></nav> {{{body}}} <footer></footer> results in <nav></nav> " [empty text node here] " <rendered view> <footer></footer> That empty text node has its own height and breaks my CSS margins and paddings. Note that if I put the view HTML directly in the layout without using handlebars templating, there is no text node and everything is fine. Any ideas

问题 When it comes to rendering a large list of items on the client-side, what are my options with Ember.js?

问题 I am trying to register helpers with Handlebars to allow iterating over JSON objects. This gist looked like an appropriate solution. I converted that into the following CoffeeScript. Nothing seems to happen when I use either of the helpers (that holds true for both vanilla JavaScript and the CoffeeScript version). Any ideas? $ -> Handlebars.registerHelper "key_value", (obj, fn)-> buffer = "" key for key in obj if obj.hasOwnProperty(key) buffer += fn({key: key, value: obj[key]}) buffer

问题 I'm having trouble getting handlebars-layouts to render in a hapi.js app. The layout renders fine but the partial doesn't render at all and just has a blank. I'm declaring it like this: var handlebars = require('handlebars'), layouts = require('handlebars-layouts'); layouts(handlebars); server.views({ engines: { html: handlebars }, basePath: __dirname, path: './views', layoutPath: './views/layout', partialsPath: './views/partials', layout: true, helpersPath: './views/helpers' }); and the

问题 I have an extensive news source (JSON), but I need to show only first three news to the user at home page. Is there a way to discard from the fourth onwards?
