handlerbar

1.first_try

初次学习，重点了解模版，可编辑context，以及最后模板注入

2.handler_register

we would create a helper named list to generate our HTML list. The helper receives the people as its first parameter, and an options hash as its second parameter. The options hash contains a property named fn, which you can invoke with a context just as you would invoke a normal Handlebars template.

Handlebars的 {{expression}} 表达式会返回一个 HTML编码 HTML-escape 过的值。如果不希望Handlebars来编码这些值，使用三个大括号即可：{{{。

Block expressions allow you to define helpers

that will invoke a section of your template with a different context than the current. These block helpers are identified by a # preceeding the helper name and require a matching closing mustache, /, of the same name.

3.paths

嵌套路径 *../*路径链接到父级模板作用域 具体怎么用？context可以有多个？？

4.Handlebars.registerHelper

想起了angular注册指令 循环

{{#each items}}
{{/each}}

注意起始和结束标记

5.this Handlebars.SafeString

Handlebars.registerHelper('agree_button',function(){
        var emotion = Handlebars.escapeExpression(this.emotion);
            name = Handlebars.escapeExpression(this.name);
        return new Handlebars.SafeString(
             "<button>I agree. I " + emotion + " " + name + "</button>"
        );
    });

6.partials

Handlebars partials allow for code reuse by creating shared templates. 模板复用 registerPartial里面写好模版

7.dynamic partials
