Angularjs filter过滤器以及自定义filter过滤器

1. Angularjs  filter过滤器

 

1. uppercase，lowercase大小转换

 

{{ "lower cap string" | uppercase }}     //结果：LOWER CAP STRING

1. 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

 

1. number格式化

 

{{ 1.234567 | number:1 }}    //结果：1.2

{{ 1234567 | number }}       //结果：1,234,567

 

1. currency货币格式化

{{ 250 | currency }}                 //结果：$250.00

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

 

1. 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"}]

 

 

1. 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"}]

 

1. 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

 

 

1. 控制器使用 filter

 

$scope.name = $filter('date')('236478234','hh');

$scope.name = $filter('uppercase')('hello');

 

 

1. Angularjs自定义filter过滤器

 

 

1. filters.js添加一个module

查看复制打印?

angular.module('tanktest', []).filter('tankreplace', function() { 

    return function(input) { 

        return input.replace(/tank/, "=====") 

    }; 

}); 

2.app.js中加载这个module

查看复制打印?

var phonecatApp = angular.module('phonecatApp', [ 

  'ngRoute', 

  'phonecatControllers', 

  'facebookControllers', 

  'tanktest' 

]); 

3.html中调用

查看复制打印?

{{ "TANK is GOOD" | lowercase |tankreplace}}   //结果：===== is good 

注意：| lowercase |tankreplace管道命令可以有多个
