一，内置的过滤器
1，uppercase，lowercase大小转换
- {{ "lower cap string" | uppercase }} //结果：LOWER CAP STRING
- {{ "TANK is GOOD" | lowercase }} //结果：tank is good
｜这里的竖线是一种管道功能，如果对linux比较熟悉的话，这块的｜根linux的管道功能，基本是一样的
2，json格式化
- {{ {foo: "bar", baz: 23} | json }} //结果：{ "foo": "bar", "baz": 23 }
注意：bza没格式前是没有双引号的，格式化后就转换成了json数据了。
3，date格式化
- {{ 1304375948024 | date }} //结果：May 3, 2011
- {{ 1304375948024 | date:"MM/dd/yyyy @ h:mma" }} //结果：05/03/2011 @ 6:39AM
- {{ 1304375948024 | date:"yyyy-MM-dd hh:mm:ss" }} //结果：2011-05-03 06:39:08
4，number格式化
- {{ 1.234567 | number:1 }} //结果：1.2
- {{ 1234567 | number }} //结果：1,234,567
5，currency货币格式化
- {{ 250 | currency }} //结果：$250.00
- {{ 250 | currency:"RMB ￥ " }} //结果：RMB ￥ 250.00
6，filter查找
- {{ [{"age": 20,"id": 10,"name": "iphone"},
- {"age": 12,"id": 11,"name": "sunm xing"},
- {"age": 44,"id": 12,"name": "test abc"}
- ] | filter:'s'}} //查找含有有s的行
- //上例结果：[{"age":12,"id":11,"name":"sunm xing"},{"age":44,"id":12,"name":"test abc"}]
- {{ [{"age": 20,"id": 10,"name": "iphone"},
- {"age": 12,"id": 11,"name": "sunm xing"},
- {"age": 44,"id": 12,"name": "test abc"}
- ] | filter:{'name':'iphone'} }} //查找name为iphone的行
- //上例结果:[{"age":20,"id":10,"name":"iphone"}]
7，limitTo字符串，对像的截取
- {{ "i love tank" | limitTo:6 }} //结果：i love
- {{ "i love tank" | limitTo:-4 }} //结果：tank
- {{ [{"age": 20,"id": 10,"name": "iphone"},
- {"age": 12,"id": 11,"name": "sunm xing"},
- {"age": 44,"id": 12,"name": "test abc"}
- ] | limitTo:1 }} //结果：[{"age":20,"id":10,"name":"iphone"}]
8，orderBy对像排序
- {{ [{"age": 20,"id": 10,"name": "iphone"},
- {"age": 12,"id": 11,"name": "sunm xing"},
- {"age": 44,"id": 12,"name": "test abc"}
- ] | orderBy:'id':true }} //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' }} //根据id升序排
二，自定filter功能
我找了一个基本angularjs的mvc框架，phonecat，自定义filter也是在这基础写的，这个框架挺好用的。
1，filters.js添加一个module
- angular.module('tanktest', []).filter('tankreplace', function() {
- return function(input) {
- return input.replace(/tank/, "=====")
- };
- });
2，app.js中加载这个module
- var phonecatApp = angular.module('phonecatApp', [
- 'ngRoute',
- 'phonecatControllers',
- 'facebookControllers',
- 'tanktest'
- ]);
3，html中调用
- {{ "TANK is GOOD" | lowercase |tankreplace}} //结果：===== is good
