Detailed introduction to Angular js filters

1、uppercase，lowercase 大小写转换

{{ "lower cap string" | uppercase }}   // 结果：LOWER CAP STRING{{ "TANK is GOOD" | lowercase }}      // 结果：tank is good

3、number 格式化（保留小数）

{{149016.1945000 | number:2}}

4、currency货币格式化

{{ 250 | currency }}            // 结果：$250.00{{ 250 | currency:"RMB ￥ " }}  // 结果：RMB ￥ 250.00

5、filter查找

输入过滤器可以通过一个管道字符（|）和一个过滤器添加到指令中，该过滤器后跟一个冒号和一个模型名称。

filter 过滤器从数组中选择一个子集

 // 查找name为iphone的行{{ [{"age": 20,"id": 10,"name": "iphone"},{"age": 12,"id": 11,"name": "sunm xing"},{"age": 44,"id": 12,"name": "test abc"}] | filter:{'name':'iphone'} }}

6、limitTo 截取

{{"1234567890" | limitTo :6}} // 从前面开始截取6位{{"1234567890" | limitTo:-4}} // 从后面开始截取4位

7、orderBy 排序

 // 根id降序排{{ [{"age": 20,"id": 10,"name": "iphone"},{"age": 12,"id": 11,"name": "sunm xing"},{"age": 44,"id": 12,"name": "test abc"}] | orderBy:'id':true }}// 根据id升序排{{ [{"age": 20,"id": 10,"name": "iphone"},{"age": 12,"id": 11,"name": "sunm xing"},{"age": 44,"id": 12,"name": "test abc"}] | orderBy:'id' }}
