如何使用angularjs将选定的复选框数据推送到数组中？

Question

我有一个由两个对象组成的表数组。每个对象都有表名。  我使用ng-repeat作为复选框。当我选中复选框时，所选对象将推入数组[tablelist]，数组将用于drodownlist。

$scope.tables=[{"tabelname":"t1},{{tabelname:t2}}]
$scope.tablelist=[]

这是我的HTML代码

<div ng-repeat="table in tables">
    <span class="col-sm-1">
    <input type="checkbox" ng-model="table.tablename" class="form-group">{{table.tablename}}</span>
</div>

<select ng-options="table.tablename as table.tablename for table in  tablelist></select>

Answer 1

<div ng-repeat="table in tables">
    <span class="col-sm-1">
    <input type="checkbox" ng-click="saveData($index)" ng-model="table.tablename" class="form-group">{{table.tablename}}</span>
</div>

<select ng-options="table.tablename as table.tablename for table in  tablelist></select>

在您的控制器中：

$scope.saveData = function(index) {
if(table.tablename)
    $scope.tablelist[index] = $scope.tables[index];
};

将表名简单传递给saveData func。然后将此名称推送到数组

<div ng-repeat="table in tables">
<span class="col-sm-1">
<input type="checkbox" ng-click="saveData(table.tablename)" ng-model="table.tablename" class="form-group">{{table.tablename}}</span></div><select ng-options="table.tablename as table.tablename for table in  tablelist></select>

确保没有现有值
