[英]How to change the innerHTML content onmouseout in angular
我必須使用Angular在mouseenter上將按鈕的內容更改為ON，在mouseleave上將按鈕的內容更改為OFF。
<html ng-app="myApp" ng-controller="homeCtrl">
<head>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('homeCtrl', function ($scope) {
$scope.alert = function () {
this.myHTML = OFF;
};
$scope.text = function () {
this.myHTML = ON;
};
})
</script>
</head>
<body>
<button ng-mouseenter="alert();" ng-mouseleave="text();"> OFF </button>
</body>
</html>
$scope.alert = function () {
$scope.text = 'OFF';
};
$scope.text = function () {
$scope.text = 'ON';
};
和
<button ng-mouseenter="alert();" ng-mouseleave="text();">{{text}}</button>
為什么不使用綁定呢？
<html ng-app="myApp" ng-controller="homeCtrl">
<head>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('homeCtrl', function ($scope) {
$scope.alert = function () {
$scope.value = "OFF";
};
$scope.text = function () {
$scope.value = "ON";
};
$scope.value="OFF"
})
</script>
</head>
<body>
<button ng-mouseenter="alert();" ng-mouseleave="text();"> {{value}} </button>
</body>
</html>
