{{}}插件表达式中是否支持过滤 about avalon HOT 2 CLOSED

    <p>avalon自带以下几个过滤器</p>
    <dl>
        <dt>html</dt>
        <dd>没有传参，用于将文本绑定转换为HTML绑定</dd>
        <dt>uppercase</dt>
        <dd>大写化</dd>
        <dt>lowercase</dt>
        <dd>小写化</dd>
        <dt>truncate</dt>
        <dd>对长字符串进行截短，truncate(number, truncation), number默认为30，truncation为“...” </dd>
        <dt>camelize</dt>
        <dd>驼峰化处理</dd>
        <dt>escape</dt>
        <dd>对类似于HTML格式的字符串进行转义，把尖括号转换为&amp;gt; &amp;lt;</dd>
        <dt>currency</dt>
        <dd>对数字添加货币符号，以及千位符， currency(symbol)</dd>
        <dt>number</dt>
        <dd>对数字进行各种格式化，这与与PHP的number_format完全兼容， number(decimals, dec_point, thousands_sep), 
            <pre>
         decimals   可选，规定多少个小数位。
         dec_point  可选，规定用作小数点的字符串（默认为 . ）。
        thousands_sep   可选，规定用作千位分隔符的字符串（默认为 , ），如果设置了该参数，那么所有其他参数都是必需的。
            </pre>
        </dd>
        <dt>date</dt>
        <dd>对日期进行格式化，date(formats)
            <pre>

            <p>例子：</p>
            <div ms-skip>
                <p>生成于{{ new Date | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "2011/07/08" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "2011-07-08" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "01-01-2000" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "03 04,2000" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "3 4,2000" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ 1373021259229 | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>生成于{{ "1373021259229" | date("yyyy MM dd:HH:mm:ss")}}</p>
                <p>值得注意的是，new Date可传的格式类型非常多，但不是所有浏览器都支持这么多，详看<a href="http://dygraphs.com/date-formats.html">这里</a></p>
            </div>
        </dd>
    </dl>
    <p>多个过滤器一起工作</p>
    <pre class="brush:html;gutter:false;toolbar:false;">

    &lt;div&gt;{{ prop | filter1 | filter2 | filter3(args, args2) | filter4(args)}}&lt;/div&gt;
    </pre>
    <p>如果想自定义过滤器，可以这样做</p>
    <pre class="brush:js;gutter:false;toolbar:false;">
          avalon.filters.myfilter = function(str, args, args2){//str为管道符之前计算得到的结果，默认框架会帮你传入，此方法必须返回一个值
             /* 具体逻辑 */
             return ret;
          }
    </pre>
