尝试使用来自指令的自定义代码使用双向数据绑定更改材料 md 选择的选项卡 [英] Trying to change the material md-selected tab using custom code from directive using two way data binding
问题描述
我正在尝试使用代码更改选项卡,但似乎无法找出错误.如果我们使用控制器来更改变量,那么基本的事情是可行的,但是当我尝试通过指令绑定它时,它就坏了.
var app = angular.module('MyApp', ['ngMaterial']);app.controller('HelloCtrl', function($scope) {$scope.selectedTab = 0;});app.directive('东西', function() {返回 {限制:'E',模板:'<div ng-click="changeNavigation()">更改导航</div>',范围: {选择标签:'='},控制器:功能($范围){$scope.changeNavigation = function() {console.log('Hello World');$scope.selectedTab = 2;};}};});
您可以在 codepen 上查看有错误的工作代码:
将 selectedTab="selectedTab"
更改为 selected-tab="selectedTab"
同时将参数传递给您的指令.

I'm trying to change the tab using code and can't seem to figure out the error. The basic thing works if we use the controller to change the variable but when I try to bind it through directive, it brokes.
var app = angular.module('MyApp', ['ngMaterial']);
app.controller('HelloCtrl', function($scope) {
$scope.selectedTab = 0;
});
app.directive('something', function() {
return {
restrict: 'E',
template: '<div ng-click="changeNavigation()">Change Navigation</div>',
scope: {
selectedTab: '='
},
controller: function($scope) {
$scope.changeNavigation = function() {
console.log('Hello World');
$scope.selectedTab = 2;
};
}
};
});
You can view the working code with error on codepen: http://codepen.io/piyushchauhan2011/pen/rVRqeV?editors=101
The error is:
Change selectedTab="selectedTab"
to selected-tab="selectedTab"
while passing parameter to your directive.
