javascript - 如何在模态对话框中获取选中的复选框行数据？

Question

我在选择任何复选框时遇到问题，只有选定的行数据应该在模型对话框中可见。

1. 但我的情况是，当我点击进程(它调用模型对话框)时，我会选择或不选择所有数据。
2. 但在点击保存数据按钮(位于模型内部)后，数据会按照我的选择正确显示。
3. 但我必须在点击保存数据按钮之前显示数据。

html code

<div class="row">
            <div class="col-md-12">

Answer 1

将模态 html 更改为

   <tr ng-repeat="x in vm.data" ng-if="x.selected">
                        <td>{{x.name}}</td>
                        <td>{{x.mobileNumber}}</td>
                    </tr>

禁用进程按钮

创建一个类似的函数

vm.isContainsSelected = function(){
return vm.data.some(function(d){return d.selected})
}

然后在处理按钮上

 <button ng-disabled="!vm.isContainsSelected()" >proceess</button>
