问题描述
我有一些麻烦结合在控制器中定义在一个指令一个回调函数的函数。我的code如下所示：
I'm having some trouble binding a function defined in a controller with a callback function in a directive. My code looks like the following:
在我的控制器：
$scope.handleDrop = function ( elementId, file ) {
console.log( 'handleDrop called' );
}
然后我的指令：
.directive( 'myDirective', function () {
return {
scope: {
onDrop: '&'
},
link: function(scope, elem, attrs) {
var myFile, elemId = [...]
scope.onDrop(elemId, myFile);
}
} );
在我的html页面：
And in my html page:
<my-directive on-drop="handleDrop"></my-directive>
有与code以上没有运气。从我在各种教程我明白读过我应该指定在HTML页面的参数呢？
Having no luck with the code above. From what I've read in various tutorials I understand I'm supposed to specify the arguments in the html page?
在您的帮助非常感谢！
