  1. 控制器使用 filter

$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
