javascript - 当前行的 ng-hide 和 ng-show

Question

我有一张表。我正在使用 Angular 进行行隐藏和显示以进行编辑和保存目的。 运行良好。

$scope.init=function(){
    $scope.editable=true;
}

现在，当我单击表格行中的编辑按钮时，编辑按钮将被隐藏并显示保存按钮。

$scope.editRow = function(id){
    console.log(id);\\row id will be displayed here
    $scope.editable=false;
}

这里面临一个问题，如果我单击第二行上的编辑，则只有第二行应该是可编辑的。
我知道我们可以使用jquery中的行id轻松地做到这一点。但在这里我不知道如何以 Angular 方式为 ng-hide 和 ng-show 执行此操作。

有任何帮助吗？谢谢!!

代码:

<table>
<thead>
<tr>                                
    <th>Qualification</th>
    <th>Course</th>
    <th>Grade Attained</th>                                
    <th>Action</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="detail in educationDetails">
    <td>
        <span ng-show="editable">{{detail.qualification}}</span>  
        <input type="text" ng-model="detail.qualification" ng-hide="editable"/>
    </td>
    <td>
        <span ng-show="editable">{{detail.education_type}}</span>   
        <input type="text" ng-model="detail.education_type" ng-hide="editable"/>
    </td>
    <td>
        <span ng-show="editable">{{detail.grade}}</span>          
        <input type="text" ng-model="detail.grade" ng-hide="editable"/>
    </td>
    <td>      
        <div ng-show="editable">
            <span><i class='fa fa-trash-o' ng-click="deleteEducationDetail(detail)"></i></span>
            <span><i class='fa fa-pencil' ng-click="editEducationDetail(detail)"></i></span>
        </div>
        <div ng-hide="editable">
            <span><i class='fa fa-floppy-o' ng-click="updateEducationDetail(detail)"></i></span>
            <span><i class='fa fa-times' ng-click="cancelEducationDetail(detail)"></i></span>
        </div>
    </td>
</tr>

</table>





$scope.init = function () {
$scope.editable = true;
}
$scope.editEducationDetail = function (detail) {
detail.editable = false;
}

为了实现这一点，您需要显示/隐藏每行的属性。您可以在 ng-init 中初始化一个属性并使用它来显示/隐藏行。您还可以使用以下代码在 html 中执行所有显示/隐藏逻辑。

<tr ng-repeat="detail in educationDetails" ng-init="detail.editable = false">
    <td>
        <span ng-show="!detail.editable">{{detail.qualification}}</span>
        <input type="text" ng-model="detail.qualification" ng-show="detail.editable" />
    </td>
    <td>
        <span ng-show="!detail.editable">{{detail.education_type}}</span>
        <input type="text" ng-model="detail.education_type" ng-show="detail.editable" />
    </td>
    <td>
        <span ng-show="!detail.editable">{{detail.grade}}</span>
        <input type="text" ng-model="detail.grade" ng-show="detail.editable" />
    </td>
    <td>
        <div ng-show="editable">
            <span><i class='fa fa-trash-o' ng-click="deleteEducationDetail(detail)"></i></span>
            <span><i class='fa fa-pencil' ng-click="detail.editable = true"></i></span>
        </div>
        <div ng-hide="editable">
            <span><i class='fa fa-floppy-o' ng-click="updateEducationDetail(detail)"></i></span>
            <span><i class='fa fa-times' ng-click="detail.editable = false"></i></span>
        </div>
    </td>
</tr>
