javascript - ng-model 不更新对象

Question

我有一个表单，旨在让用户编辑一些信息

我的问题是 <input class="form-control" type="text" ng-repeat="info in item.Question" ng-model="info"/> 。当我单击“保存”按钮时，日志(下面复制的示例)告诉我它没有更新模型。谁能明白为什么吗？

我读到了其他一些问题，说 ng-model 需要一个 object.property 值，但我不知道如何在这里应用它

<div class="panel panel-primary" ng-show="item.edit">

<div class="panel-heading">
    <h3 class="panel-title">
        <form class="form-group form-inline">
            <input class="form-control" type="text" ng-model="item.Name" />
            <span class="badge pull-right">&#8356;<input class="form-control" type="number" step="any" ng-model="item.Price" /></span>
        </form>
    </h3>
</div>
<div class="panel-body">
    <input class="form-control" type="text" ng-model="item.Desc" />
    <hr>
    <div class="col-md-11">
        <input class="form-control" type="text" ng-repeat="info in item.Question" ng-model="info"/>
    </div>
    <div class="col-md-1">
        <a href="" ng-click="cat.newQuestion(item)" class="btn btn-success"><span class="glyphicon glyphicon-plus"></span></a>
    </div>
</div>
<div class="panel-footer">
    <div class="btn-group">
        <a href="" ng-click="cat.change(item)" class="btn btn-success">Save</a>
        <a href="" ng-click="item.edit = false" class="btn btn-primary">Cancel</a>
        <a href="" ng-click="cat.deleteItem(item)" class="btn btn-danger">Delete</a>
        </div>
    </div>
</div>

来自 change() 的日志示例功能:

app.js:39 Object {ID: "10", Name: "New User", Price: 0, Desc: "Create a new user for the Quarriers network", CatID: "3"…}$$hashKey: "object:50"CatID: "3"Desc: "Create a new user for the Quarriers network"ID: "10"Name: "New User"Price: 0Question: "username,"edit: true
app.js:40 stringing
app.js:46 Object {ID: "10", Name: "New User", Price: 0, Desc: "Create a new user for the Quarriers network", CatID: "3"…}$$hashKey: "object:50"CatID: "3"Desc: "Create a new user for the Quarriers network"ID: "10"Name: "New User"Price: 0Question: "username,"edit: true__proto__: Object

如果您不想将 Question 更改为具有属性的对象，您可以使用以下内容:

<input ng-repeat="info in item.Question track by $index" ng-model="item.Question[$index]"/>
