这里给大家分享一则input指令的使用示例

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
</head>
<script src="http://localhost:81/js/jquery.js">
</script>
<script src="http://localhost:81/js/angular.min.js">
</script>
<body ng-app="Demo">
<div ng-controller="TestCtrl">
    <input type="text" ng-model="a" test />
    <button ng-click="show(a)">查看</button>
</div>
</body>
<script>
   var app = angular.module('Demo', [], angular.noop);
   app.directive('test', function(){<br>　　　//input 指令的 link有第四个参数，$ctrl有些方法，你可以自己拿来用
     var link = function($scope, $element, $attrs, $ctrl){
    console.log( $ctrl )
       $ctrl.$formatters.push(function(value){
         return value.join(',');
       });
       $ctrl.$parsers.push(function(value){
         return value.split(',');
       });
     }
     return {compile: function(){return link},
             require: 'ngModel',
             restrict: 'A'}
   });
   app.controller('TestCtrl', function($scope){
     $scope.a = [];
     //$scope.a = [1,2,3];
     $scope.show = function(v){
       console.log(v);
     }
   });
</script>
</html>
