Angular js双向数据绑定问题,以管理"文本框"到"标签"的变化

Question

我正在使用具有"编辑"字段的数据模型.并基于"编辑"值我使用文本框或标签.我希望一旦用户在编辑后点击"确定"然后文本框应该更改为标签.但不知怎的,它不起作用.以下是jsfiddle示例.请帮忙.

我修改了你的小提琴,你必须把它改成这样的东西

<div ng-app="" ng-controller="controller" id="contentsDivID">
<div ng-repeat="chapter in chapters">
<ng:switch on="chapter.edit">
            <div ng:switch-when="true">
                <input type="text" ng-model="chapter.title" ng-model="chapter.title" />                
                <a ng-click="addChapter($index);"><i class="icon-ok"></i></a>
            </div>          
            <div ng:switch-when="undefined">
                    <label>{{chapter.title}}</label>
            </div>
            </ng:switch>        
    </div>       
</div>

然后你的JavaScript代码到此

function controller($scope)
{
    $scope.chapters=[
            {
                "_id": "567456746",
                "title": "Growth and Development",
                "type": "section",
                "edit":true
            },
            {
                "_id": "34563465345",
                "title": "Links between Areas of Development",
                "type": "section"
            },
            {
                "_id": "8776545645",
                "title": "Characteristics of Development",
                "thumbnail": "/xopus/images/templates/media-1-top-right.png",
                "type": "section"
            }
        ];

    $scope.addChapter = function(index) {
        $scope.chapters[index].edit = undefined;
    }
}
