AngularJS 事件

AngularJS 有自己的 HTML 事件指令。

ng-click指令:

ng-click 指令定义了 AngularJS 点击事件。

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>

<div ng-app="myApp" ng-controller="myCtrl">

<button ng-click="count = count + 1">点我!</button>

<p>{{ count }}</p>

</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.count = 0;
});
</script>

</body>
</html>

隐藏HTML元素:

ng-hide 指令用于设置应用部分是否可见。

ng-hide="true" 设置 HTML 元素不可见。

ng-hide="false" 设置 HTML 元素可见。

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>

<div ng-app="myApp" ng-controller="personCtrl">

<button ng-click="toggle()">隐藏/显示</button>

<p ng-hide="myVar">
名: <input type=text ng-model="firstName"><br>
姓: <input type=text ng-model="lastName"><br><br>
姓名: {{firstName + " " + lastName}}
</p>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('personCtrl', function($scope) {
    $scope.firstName = "John";
    $scope.lastName = "Doe";
    $scope.myVar = false;
    $scope.toggle = function() {
        $scope.myVar = !$scope.myVar;
    }
});
</script>

</body>
</html>

显示HTML元素:

ng-show 指令可用于设置应用中的一部分是否可见 。

ng-show="false" 可以设置 HTML 元素 不可见。

ng-show="true" 可以以设置 HTML 元素可见。

以下实例使用了 ng-show 指令:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="http://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>

<div ng-app="myApp" ng-controller="personCtrl">

<button ng-click="toggle()">隐藏/显示</button>

<p ng-show="myVar">
名: <input type=text ng-model="person.firstName"><br>
姓: <input type=text ng-model="person.lastName"><br><br>
姓名: {{person.firstName + " " + person.lastName}}
</p>

</div>

<script>
var app = angular.module('myApp', []);
app.controller('personCtrl', function($scope) {
    $scope.person = {
        firstName: "John",
        lastName: "Doe"
    };
    $scope.myVar = true;
    $scope.toggle = function() {
        $scope.myVar = !$scope.myVar;
    };
});
</script>

</body>
</html>
