javascript - ng-change 不适用于 ng-select

Question

我正在使用由 ng-options 填充的选择框。不幸的是，我无法调用我的 ng-change 函数。

Here is my Fiddle

这是我的js:

var myApp = angular.module('myApp',[]);


function MyCtrl($scope) {

    $scope.typeOptions = [
    { name: 'Feature', value: 'feature' }, 
    { name: 'Bug', value: 'bug' }, 
    { name: 'Enhancement', value: 'enhancement' }
    ];

    $scope.scopeMessage = "default text";
    var changeCount = 0;

    $scope.onSelectChange = function()
    {
       changeCount++;
        this.message = "Change detected: " + changeCount;
    }.bind($scope);

    //$scope.form = {type : $scope.typeOptions[0].value};
    $scope.form = $scope.typeOptions[0].value;
}

这是我的 HTML:

<div ng-controller="MyCtrl" class="row">
    <select ng-model='form' required ng-options='option.value as option.name for option in typeOptions' ng-change="onSelectChange"></select>

    <div style="border:1px solid black; width: 100px; height:20px;">{{scopeMessage}}<div>
</div>

这目前阻碍了我的工作项目，因此我们将不胜感激任何帮助。谢谢!

两件事...都很简单:)

1. ng-change=onSelectChange 应该是 onSelectChange()
2. this.message 应该是 this.scopeMessage
