格式化input输入内容（金额）

项目中要用到格式化金额输入框，要求每三个数字用逗号分割开。

添加一个directive

 1 angular.module('myApp.directives', [])
 2 .directive('filterInput',['$filter', function ($filter){
 3             return {
 4                 restrict: 'A',
 5                 require: 'ngModel',
 6                 link: function(scope, element, attr, ngModel) {
 7 
 8                     ngModel.$parsers.push(function fromUser(text) {
 9                         return parseInt(text.replace(",",""));
10                     });
11 
12                     ngModel.$formatters.push(function toUser(text) {
13                         console.log($filter('number')(text));
14                         return ($filter('number')(text || ''));
15                     });
16 
17                 }
18             };
19         }]);
