First, my handlebar runtime is handlebars v4.0.5 (js file). The output of handlebar -v is 4.0.5 This is my gulpfile.js : var gulp = require('gulp'); var uglify = require('gulp-uglify'); var handlebars = require('gulp-handlebars'); var wrap = require('gulp-wrap'); var declare = require('gulp-declare'); var concat = require('gulp-concat'); gulp.task('default', ['templates','scripts'], function () { }); gulp.task('templates',

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: In my Handlebars template I check for the existence of a variable, and render some text if it's there: {{#if foo}} some text {{/if}} This works fine if foo is text or if foo is numeric but not zero. But if var foo = 0; then {{#if foo}} returns false. This appears to be yet another Javascript oddity, because Javascript itself behaves the same way. In Javascript code, though, you could get around this by checking if the variable is 'undefined'. How can I do the same thing in Handlebars? I could write an {{#exists}} helper, but I was hoping

Since we are using yeoman/grunt, I have come across this handlebars plugin . I have configured it as follows: handlebars: { compile: { options: { namespace: 'JST' }, files: { '<%= yeoman.dist %>/scripts/templates.js': [ '<%= yeoman.app %>/templates/*.hbs' ], } } } As suggested in the "Usage examples" section of the plugin. This is working as expected, generating a dist/scripts/templates.js file. But putting the templates in

Here's what I've got: $.ajax({ url : 'http://twitter.com/statuses/user_timeline/alexlande.json', dataType : 'jsonp', success : function( tweets ) { var source = $('#tweet-template').html(); var template = Handlebars.compile(source); var context = tweets; $('#container').html(template(context)); } }); That doesn't display anything in my template, but the following code works as expected: var source = $('

The layout (layout.hbs) looks like this: {{{body}}} The {{{body}}} is replaced server-side, within node.js when you access a route. For example: app.get('/', function(req, res){ res.render('index'}) }) Will replace the {{{body}}} tag with the contents of index.hbs. Now, on the client side I'm using Backbone.js and want to use Handlebars for the views controlled via Backbone. The problem is that because these pages

H5中都是Html，在这里我们没有el标签。所以我们只能借助模板。好处上面已经介绍了 扫码关注公众号，不定期更新干活 web 开发中，js 解析JSON 是经常的事情。非常繁琐。handlebars 使用了模版，只要你定义一个模版，提供一个json对象，handlebars 就能吧json对象放到你定的模版中，非常方便好用！ H5中都是Html，在这里我们没有el标签。所以我们只能借助模板。好处上面已经介绍了。 第一步：在html中定义模板，将后台的json放在模板里。 <script id="task-table-template" type="text/x-handlebars-template"> {{#each this}}//遍历循环的格式，相当于foreach <a href="{{link}}">//json中的link必须是{{}}格式 <strong> {{Obj_title}}//同上 </strong> </a> {{/each}} </script> 第二步：在js中实例化这个模板 var myTemplate = Handlebars.compile($("#task-table-template").html()); 第三步：将后台json传进来显示，并确定模板显示位置，下面的列子 将模板显示在class=notice_srcoll的div上 $('
