一、内置过滤器
1、大小写转换:
uppercase、lowercase
{{"lower cap string"| uppercase }}
{{"Tank Is GOOD"| lowercase}}
2、json格式化(将对象转换成json字符串),默认输出就是json字符串:
{{ {name:'zhangsan',age:15} }}
{{ {name:'zhangsan',age:15}|json }}
3、number格式化:
{{1.2345|number:1}} // 1.2
{{1.2345|number:3}} // 1.235
{{1234567|number}} // 1,234,567
4、currecy货币格式化:
{{500|currency}} // $500.00
{{250|currency:'RMB ¥ '}} // RMB ¥ 250.00
5、date格式化:
var app = angular.module('myApp', []);
app.controller('myCtrl', function ($scope) {
$scope.dateOne = new Date();
console.info(new Date().toJSON());
$scope.dateTwo = new Date().toJSON();
// /Date(1464941268937)/
$scope.dateThree = '1464941268937';
});
{{ 1304375948024 |date}} // May 3, 2011
{{ dateOne |date:'hh:mm:ss'}} // 09:19:20
{{ dateTwo |date:'yyyy-MM-dd hh:mm:ss'}} // 2017-09-19 09:19:20
{{ dateThree |date:'yyyy年MM月dd日'}} // 2016年06月03日
6、filter查找:
//查找含有有4的行
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}]
| filter:'4' }}
//查找name含有iphone的行
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}]
| filter:{'name':'iphone'} }}
//查找含有有4的行
[{"age":44,"id":12,"name":"test abc"}]
//查找name含有iphone的行
[{"age":20,"id":10,"name":"iphone"}]
7、limitTo 字符串或对象的截取:
{{'i want you'| limitTo:3}} // i w
{{'i want you'| limitTo:-3}} // you
{{[1,3,5]|limitTo:1}} // [1]
{{[1,3,5]|limitTo:-1}} // [5]
8、orderBy 对象排序:
//根据id降序排
{{ [{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}]
| orderBy:'id':true }}
//根据id升序排
{{[{"age": 20,"id": 10,"name": "iphone"},
{"age": 12,"id": 11,"name": "sunm xing"},
{"age": 44,"id": 12,"name": "test abc"}]
| orderBy:'id'}}
//根据id降序排
[{"age":44,"id":12,"name":"test abc"},{"age":12,"id":11,"name":"sunm xing"},{"age":20,"id":10,"name":"iphone"}]
//根据id升序排
[{"age":20,"id":10,"name":"iphone"},{"age":12,"id":11,"name":"sunm xing"},{"age":44,"id":12,"name":"test abc"}]
二、自定义过滤器
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.msg = "Runoob";
});
app.filter('reverse', function() { //可以注入依赖
return function(text) {
return text.split("").reverse().join("");
}
});
