angularjs filter 过滤器例子

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
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

{{ 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
第一个参数可以是：字符串，对象，函数

{{ [{“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”}]

{{ [‘Ari’,’likes’,’to’] | filter:run }}

//上例结果: [“Ari”]

$scope.run=function(str){
return str[0]==str[0].toUpperCase();
}
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
9,自定义过滤器filter
将字符串的首字母换成大写
angular.module(‘myapp’,[]).filter(‘myfilter’,function(){
return function(str){
if(str){
return input[0].toUpperCase()+str.slice(1);
}
}
})
{{‘my name is chenge’ | lowercase | myfilter}}

//结果：My name is chenge
