实现一个简单的input清空内容，且清空对应ngModel
前台部分
<html ng-app="hpapp">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="css/test.css">
<script type="text/javascript" src="js/angular.js"></script>
<script type="text/javascript" src="js/inputempty.js"></script>
<script type="text/javascript" src="js/info.js"></script>
</head>
<body>
<div ng-controller="InfoCtrl">
<input type="text" name="email" ng-model="model.email" inputempty maxvalue="10">
<br>
<br>
<br>
<input type="text" name="text" ng-model="model.text" inputempty>
<br>
<br>
<br> {{model.email +"*"+ model.text}}
</div>
</body>
</html>
控制器部分 info.js
1 var app = angular.module(‘hpapp‘);
2 app.controller(‘InfoCtrl‘, function($scope) {
3 $scope.model = {
4 email: ‘1073520680‘,
5 text: ‘‘
6 };
7 });
指令部分
var app = angular.module(‘hpapp‘, []);
app.directive(‘inputempty‘, function() {
return {
restrict: ‘A‘,
require: ‘ngModel‘,
link: function(scope, elem, attrs, ctrl) {
var close = ‘<span class="clear"></span>‘;
elem.next().bind(‘click‘, function() {
ctrl.$setViewValue(‘‘);
elem.val(‘‘);
});
}
};
});
ctrl.$setViewValue(‘‘);//清空ngModel elem.val(‘‘);//清空表单
