我刚刚开始学习 Angular,我尝试制作 concat var name,以便我可以动态控制它。

这是我尝试过的 -

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

<button ng-click="myFunc(1)">Click Me!</button>

<div ng-show="showMe1">
<h1>Menu:</h1>
<div>Pizza</div>
<div>Pasta</div>
<div>Pesce</div>
</div>

</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.showMe1 = false;
$scope.myFunc = function(x) {
var nametocng = 'showMe'+x;
//var nametocng = $parse("showMe"+x); // - I tried this also
$scope.nametocng = !$scope.nametocng;
}
});
</script>

最佳答案

使用$scope[variable]进行动态。

来自您的评论: 最后,我想制作多个切换,但我想要一个功能用于所有这些切换。然后,每个按钮都会处理一个切换

您可以使用ng-repeat作为按钮来处理不同的菜单

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

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

<button ng-repeat="button in array" ng-click="myFunc(button)">Click Me!</button>

<div ng-show="showMe1">
<h1>Menu:</h1>
<div>Pizza1</div>
<div>Pasta1</div>
<div>Pesce1</div>
</div>

<div ng-show="showMe2">
<h1>Menu:</h1>
<div>Pizza2</div>
<div>Pasta2</div>
<div>Pesce2</div>
</div>
{{nametocng}}

</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.array = [1,2];
$scope.firstName = "John";
$scope.lastName = "Doe";

$scope.myFunc = function(x) {
angular.forEach($scope.array, function(value, key){
$scope['showMe'+value] = false
});
var nametocng = 'showMe'+x;
//var nametocng = $parse("showMe"+x); // - I tried this also
$scope[nametocng] = !$scope[nametocng];
}
});
</script>

</body>
</html>

请运行上面的代码片段
