问题 Is there a clean, recomended way to access the mountpath from inside a template, so an express app can be run both standalone and as a part of another app (by means of app.use), with the paths pointing to the correct destination either way? Something like: {{mountpath}}route/to/file So in the case that the app is running standalone, mountpath will be / , and in case is running as a submodule, mountpath could be /foo/ Note: I'm using handlebars. 回答1: express.static middleware is responsible

问题 Haven't been able to find out any answers to this so far but I'm trying to use handlebars within tumblr's theme system and it looks like my {{variables}} are getting overwritten from tumblr and then my content is never displayed. For example my handlebars template has <img src="{{bgimage}}" class="img-responsive"> But it will output as <img src="{}" class="img-responsive"> So it looks like tumblr is just removing it. I have seen others use handlebars within a theme however I just can't figure

Example: // Template.html <p>{{myHelper 'This is an awsome {name}'}}</p> Helper.js Handlebars.registerHelper('myHelper', function(string){ // string is 'This is an awsome {name}' AND it is important that {name} is a string and at this point not the real value var myNewString = string.replace(\{name}\,

问题 Can't understand how to escape { or } symbols standing next to expression at handlebars java templating engine. I'm using handlebars templates to generate plain text so I can't use HTML ASCII codes of braces as advised there. I need expression like \{{{variable.name}}\} to be resolved to {variable.value} . Should I create helpers for that or there is a cleaner way? 回答1: Here are some examples of escaping. The last method escape with a helper (when the other methods are not possible). $

问题 I have a menu bar whose status/color etc changes when clicked. These belong to different JSP/HTML pages. When I click on the page, there is a handlebar #bindAttr which decides the class of the each tabbed menuitem. For e.g. <li id="index" {{#bindAttr class="active"}}> <a href="./index.jsp"> <i class="icon-dashboard"></i> <span>Dashboard</span> </a> </li> What I need here is also to pass something else so that the computed property can find out based on the location.href whether this class

问题 I am writing a front-end code for a website using jQuery and AJAX and Handlebars.js. I have HTML,CSS and script.js files. I am pretty new to Javascript and techniques. This is the first time i'm using Handlebars in my code. I used JSON parsing to parse through the entire data provided in a URL.

问题 I been trying to compare some values in handlebars if statement {{#if value == 'otherValue'}} , obviously unsuccessfully because handlebars do not like this and expecting a string, boolean, or function name.
