问题 Quoting Handlebars FAQ: How can I include script tags in my template? If loading the template via an inlined tag then you may need to break up the script tag with an empty comment to avoid browser parser errors: <script type="text/x-handlebars"> foo <scr{{!}}ipt src="bar"></scr{{!}}ipt> </script> Nevertheless, I can't seem to be able to implement this: document.getElementById('output').innerHTML = Handlebars.compile( document.getElementById("template").innerHTML )({}); <script src="https:/

问题 I'm in the process of rewriting some older code, and using Vue as the replacement. It's all going great apart from changing one table that is templated using handlebars. Using handlebars nested {{each}} I can work down through the nested data structure while displaying the relevant data in table rows: e.g. using handlebars: https://jsfiddle.net/6dsruo40/1/ I cant figure out how to do the same using Vue with v-for etc. Fiddle with as mush as I have: https://jsfiddle.net/cj7go6bv/ I don't know

问题 I have a handlebars template that works great. I'd like to be able to put the following in it: <script id="someTemplate" type="text/x-handlebars-template"> <div class="editStuff"> <span {{#if aThing}} data-someKey="{{anotherThing}}" {{/if}}> {{aThirdThing}} </span> </div> </script> This obviously would render when the handlebars file is processed. all of the {{}}'s end up being blank, no good. I found the {{{{raw-helper}}}} block helper, and tried it out like so: {{{{raw-helper}}}} <script id

问题 I'm attempting to write my own handlebars helpers and am getting no where. I'm using the npm hbs package (Handlebars.registerHelper didn't work) and registering it in app.js like so: app.set('view engine', 'hbs'); var hbs = require('hbs'); hbs.registerHelper("log", function(something) { return console.log(something); }); hbs.registerHelper('test', function() { return console.log('test') }); Yet {{log 'test'}} or {{test}} any where inside my template does absolutely nothing. There's no js

问题 I am trying to assign values within a template, the idea is to do something like this: {{#if author}} {{className = 'classA'}} <- trying to implement this line. {{else}} {{className = 'classB'}} {{/if}} <div class={{className}}></div> Is it possible to do so without registerHelper? 回答1: You can do this with a partial. partial: <div class="{{classname}}">{{var1.author}}</div> template: {{#if author}} {{> mypartial var1=. classname="classA"}} {{else}} {{> mypartial var1=. classname="classB"}} {

问题 This question already has an answer here : Bootstrap navbar: nothing is displayed on smaller devices (1 answer) Closed 19 days ago . I am trying to get my bootstrap navbar implemented into my handlebars layout file. I've noticed some weird things happening with bootstrap and this is no exception. Once I shrink my window to a size where the navbar-toggler-icon should show, it is not visible, but it is still functioning there like it should, I just can't see it. Here is my entire layout.hbs

问题 Is it possible in Handlebars to check if a string is equal to another value without registering a helper? I can't seem to find anything relevant to this in the Handlebars reference. For example: {{#if sampleString == "This is a string"}} ...do something {{/if}} 回答1: It seems you can't do it "directly" Try use helper, why not? Register helper in your javascript code: Handlebars.registerHelper('ifEquals', function(arg1, arg2, options) { return (arg1 == arg2) ? options.fn(this) : options.inverse

问题 I want display different HTML depending on a condition. It doesn't seem to compare those two values and it always shows the first variant. How can I compare the predefined values to the original value from JSON so that it can execute properly? {{#each this}} {{#each visits}} <div class="row"> {{#if variable_from_json }} <div class="col-lg-2 col-md-2 col-sm-2"> <i class="fa fa-home"></i> </div> {{else}} <div class="col-lg-2 col-md-2 col-sm-2"> <i class="fa fa-plus symbol-hospital"></i> </div>

问题 I have an array of json objects which I output using a Handlebars template; I am currently doing using {{#each object}}...{{/each}}. I now need to sort the objects by one of the object's properties, which again is no problem using a handlebars helper & coffeescript, however, I have a problem in my template in that I cannot work out how to iterate over the sorted array using each. My research so far indicates that I probably need to write a custom Handlebars helper which will, in effect, be: {

问题 I and the team got a task to implement multiple themes for our project (keeping in mind that we have a single-theme project right now). By theme I don't mean just CSS , I mean different markup files, certain features for certain things, etc. (If you don't like the word 'theme' in this context don't use it, I hope you get the idea: some things need to be reused across the codebase, some things need to be specific to a theme ). Overall, we have no problem of structuring it in a maintainable way
