使用此代码：
<!doctype html>
<html lang="en" ng-app="app">
<head>
<Meta charset="UTF-8">
<title>ngTest</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.js"></script>
<script>
angular
.module('app',[])
.controller('Main',['$scope',function($s) {
$s.data = {
level1: {
level2: {
elements: [{
name: 'item1'
},{
name: 'item2'
},{
name: 'item3'
},{
name: 'item4'
}]
}
}
};
}]);
</script>
</head>
<body ng-controller="Main">
<div ng-repeat="item in data.level1.level2.elements">
<input type="file" ng-model="item.name">
</div>
<pre>{{data}}</pre>
</body>
会引发这个错误：
Error: An attempt was made to use an object that is not,or is no longer,usable.
一旦将type =“file”更改为type =“text”,错误就会消失.知道怎么解决这个问题吗？我将编写一个指令,即使在输入上也会监听更改,上传给定文件并将其值分配给绑定模型.但我这个错误阻止了我这样做.最近几天花了我很多头发.对此事的任何意见都将不胜感激.
