ng-click 指令
点击加减运算
<div ng-app="myApp" ng-controller="myCtrl">
<button ng-click="count = count + 1">加！</button>
<button ng-click="count = count - 1">减！</button>
<p>{{ count }}</p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.count = 0;
});
</script>
点击进行隐藏显示切换
<div ng-app="myApp" ng-controller="personCtrl">
<button ng-click="toggle()">隐藏/显示</button>
<p ng-hide="myVar">
名: <input type=text ng-model="firstName"><br>
姓: <input type=text ng-model="lastName"><br><br>
姓名: {{firstName + " " + lastName}}
</p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('personCtrl', function($scope) {
$scope.firstName = "John",
$scope.lastName = "Doe"
$scope.myVar = false;
$scope.toggle = function() {
$scope.myVar = !$scope.myVar;
}
});
</script>
应用解析:
第一部分 personController与控制器章节类似。
应用有一个默认属性: $scope.myVar = false;
ng-hide 指令设置 <p>元素及两个输入域是否可见， 根据 myVar 的值 (true 或 false) 来设置是否可见。
toggle() 函数用于切换 myVar 变量的值（true 和 false）。
ng-hide="true" 让元素 不可见。
ng-show
<div ng-app="myApp" ng-controller="personCtrl">
<button ng-click="toggle()">隐藏/显示</button>
<p ng-show="myVar">
名: <input type=text ng-model="person.firstName"><br>
姓: <input type=text ng-model="person.lastName"><br><br>
姓名: {{person.firstName + " " + person.lastName}}
</p>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('personCtrl', function($scope) {
$scope.person = {
firstName: "John",
lastName: "Doe"
};
$scope.myVar = true;
$scope.toggle = function() {
$scope.myVar = !$scope.myVar;
};
});
</script>
