@H_502_3@
@H_502_3@
@H_502_3@@H_502_3@
@H_502_3@
<span style="font-size:18px;">{{ {'name': 'Ari','City': 'SanFrancisco'} | json }}

<span style="font-size:18px;">{{ 123456789 | number }}
<!-- 1,234,567,890 --></span>
我们将下面的对象数组用 name 字段进行排序：
@H_502_3@
@H_502_3@
@H_502_3@@H_502_3@
@H_502_3@
<span style="font-size:18px;">{{ [{

.filter('capitalize',function() {
return function(input) {
// input是我们传入的字符串
if (input) {
return input[0].toUpperCase() + input.slice(1);
