问题描述
我想利用设置NG-init中的$ scope属性的值，我无法访问控制器的JavaScript该值。我究竟做错了什么？这里是一个小提琴： http://jsfiddle.net/uce3H/
I am trying to set the value of a $scope property using ng-init, and I am unable to access that value in the controller's javascript. What am I doing wrong? Here is a fiddle: http://jsfiddle.net/uce3H/
标记：
<body ng-app>
<div ng-controller="testController" >
<input type="hidden" id="testInput" ng-model="testInput" ng-init="testInput='value'" />
</div>
{{ testInput }}
</body>
JavaScript的：
javascript:
var testController = function ($scope) {
console.log($scope.testInput);
}
在javascrippt，$ scope.testInput是不确定的。不应该是价值？
In the javascrippt, $scope.testInput is undefined. Shouldn't be 'value'?
推荐答案
您正在尝试角完成分配之前阅读设定值。
You are trying to read the set value before Angular is done assigning.
演示：
var testController = function ($scope, $timeout) {
console.log('test');
$timeout(function(){
console.log($scope.testInput);
},1000);
}
在理想情况下，你应该使用 $观看由@Beterraba建议摆脱定时器：
Ideally you should use $watch as suggested by @Beterraba to get rid of the timer:
var testController = function ($scope) {
console.log('test');
$scope.$watch("testInput", function(){
console.log($scope.testInput);
});
}
