Question

我是新来的，任何人都可以告诉我如何从索引中获取已检查记录ID以使用 Ajax 和 Jquery 删除所选记录这是我的表单和ajax脚本用于选择此代码不执行任何操作，请告诉我

<div class="usermaster-model-index">
    <input type="button" class="btn btn-info pull-right" value="Delete Multiple" id="MyButton" >
    <h1><?= Html::encode($this->title) ?></h1>
    <?php
    ?>
    <p>
        <?= Html::a('Create Usermaster Model', ['create'], ['class' => 'btn btn-success']) ?>
    </p>
    <?=
    GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        //'class' => ActionColumn::className(),
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            'user_fname',
            'user_id',
            'user_lname',
            'user_mobile',
            ['class' => 'yii\grid\ActionColumn'],
            [ 'class' => 'yii\grid\CheckboxColumn',
                'checkboxOptions' => ["attribute" => 'user_id'],
            ],
        ],
    ]);
    ?>
</div>

<script>
    $(document).ready(function () {
        $('#MyButton').click(function () {
             alert('hello'); 
            var HotId = $('#user_id').yiiGridView('getSelectedRows');
            $.ajax({
                type: 'POST',
                cache: false,
                url: Url::toRoute('usermaster/MultipleDelete'),
                data: {user_id: HotId},
                success: function () {
                 $(this).closest('tr').remove(); 
               }
            });

        });
    });
</script>

这里我的控制器动作删除多个数据函数以获取所选的id并删除

public function actionMultipleDelete()
{
    $data = Yii::$app->request->post('user_id');
    foreach ($data as $key => $value) 
    {
        $sql = "DELETE FROM usermaster WHERE user_id = $value";
        $query = Yii::$app->db->createCommand($sql)->execute();
    }
    return $this->redirect(['index']);
}

在您的gridview中添加id选项

GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'id'=> your-id //set your id here and use this is in jquery
        //'class' => ActionColumn::className(),
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            'user_fname',
            'user_id',
            'user_lname',
            'user_mobile',
            ['class' => 'yii\grid\ActionColumn'],
            [ 'class' => 'yii\grid\CheckboxColumn',
                'checkboxOptions' => ["attribute" => 'user_id'],
            ],
        ],
    ]);

并在Jquery中用您的新ID替换user_id，如下所示。

<script>
    $(document).ready(function () {
        $('#MyButton').click(function () {
             alert('hello'); 
            var HotId = $('#your-id').yiiGridView('getSelectedRows'); // modify this line
            $.ajax({
                type: 'POST',
                cache: false,
                url: Url::toRoute('usermaster/MultipleDelete'),
                data: {user_id: HotId},
                success: function () {
                 $(this).closest('tr').remove(); 
               }
            });

        });
    });
</script>

我希望在yii2中检查多个记录ID
