Handlebars也挺有意思的

Handlebars是一个模板

    var tpl2='\
    <ul class="list_top layoutfix">\
    <li class="w_01">名称</li>\
    <li class="w_02">原价</li>\
    <li class="w_03">111</li>\
    <li class="w_04">优惠</li>\
    <li class="w_05">{{age}}</li>\
    </ul>\
    ';
    var html = Handlebars.compile(tpl2)({'age': 12});
    document.body.innerHTML = html;

你可以自定义方法，让它变成和angular一样灵活

//相等
Handlebars.registerHelper('equal', function (a, b, v1, v2) {
                return a == b ? v1 : v2;
            });

//或者这样，它就像一个过滤器
Handlebars.registerHelper('regcheck', function (a) {
                var reg = {
                    "1": "checkIdCard",
                    "2": "checkPassport",//护照
                    "10": "checkHKCard",//港澳通行证
                    "22": "checkTAIWAN",//台湾通行证
                    "6": "checkDriver"//驾驶证
                };
                return !!reg[a] ? reg[a] : "checkCard";

            });

 //还可以这样
// if增强 {{#ifPlus var1 '==' var2}}
Handlebars.registerHelper('ifPlus', function(v1, operator, v2, options) {

        switch (operator) {
            case '==':
                return (v1 == v2) ? options.fn(this) : options.inverse(this);
            case '===':
                return (v1 === v2) ? options.fn(this) : options.inverse(this);
            case '<':
                return (v1 < v2) ? options.fn(this) : options.inverse(this);
            case '<=':
                return (v1 <= v2) ? options.fn(this) : options.inverse(this);
            case '>':
                return (v1 > v2) ? options.fn(this) : options.inverse(this);
            case '>=':
                return (v1 >= v2) ? options.fn(this) : options.inverse(this);
            case '&&':
                return (v1 && v2) ? options.fn(this) : options.inverse(this);
            case '||':
                return (v1 || v2) ? options.fn(this) : options.inverse(this);
            default:
                return options.inverse(this);
        }
    });  
Handlebars.registerHelper('list', function(items, options) {
      var out = "<ul>";
      for(var i=0, l=items.length; i<l; i++) {
        out = out + "<li>" + options.fn(items[i]) + "</li>";
      }
      return out + "</ul>";
});
//还能这样玩，仿佛是组件的雏形
var tpl3 = "{{#list people}}{{firstName}} {{lastName}}{{/list}}";
var data3 ={
  people: [
    {firstName: "Yehuda", lastName: "Katz"},
    {firstName: "Carl", lastName: "Lerche"},
    {firstName: "Alan", lastName: "Johnson"}
  ]
}
var html = Handlebars.compile(tpl3)(data3);
document.body.innerHTML= html;             

有时候 需要传入一段html 我们可以使用{{{三个括号 更多可能等你探索 handlebarapi handlebar官网
