这是checkboxOptions前选框的用法

use yii\grid\GridView;

$this->registerJs("

$('#selection_all').click(function(){

$('input[name=selection_all]').click();

});

$('#delete_select').click(function(){

var selection = $('#w0').yiiGridView('getSelectedRows');

if(selection.length==0){

alert('未选中');

return false;

}else{

if(confirm('您确定要删除吗?')==true){

$.post('".Url::to(['product-base/delete-select'])."', {selection:selection});

location=location;

}else{

location=location;

}

}

});

$('#up_select').click(function(){

var selection = $('#w0').yiiGridView('getSelectedRows');

if(selection.length==0){

alert('未选中');

return false;

}else{

$.post('".Url::to(['product-base/status-select'])."', {selection:selection,status:1});

location=location;

}

});

$('#down_select').click(function(){

var selection = $('#w0').yiiGridView('getSelectedRows');

if(selection.length==0){

alert('未选中');

return false;

}else{

$.post('".Url::to(['product-base/status-select'])."', {selection:selection,status:0});

location=location;

}

});

", \yii\web\View::POS_END);

<?= GridView::widget([

'layout' => "{items}<div class='row'>

<div class='btn-group col-md-3'>

<button class='btn btn-warning' id='selection_all'>全选</button>

<button class='btn btn-default' id='up_select'>上架</button>

Controller中的写法：

public function actionDeleteSelect(){

//删除selection

$selection = Yii::$app->request->post('selection');

ProductBase::deleteAll(['id'=>$selection]);

}

//改变状态

public function actionStatusSelect(){

//找到选中的

$selection = Yii::$app->request->post('selection');

//找到post过来的

$status = Yii::$app->request->post('status');

ProductBase::updateAll(['status'=>$status],['id'=>$selection]);

}
