无法将数据从视图发布到Yii2中的控制器

标签: javascript jquery ajax gridview yii2

我正在研究Yii2。我有一个带有复选框的gridview,并在一个按钮上单击,使用Ajax将其重定向到动作控制器。

 <?= Html::a('Disconnect', ['dco'], ['class' => 'btn btn-success', 'id'=>'dco']) ?>

<?php Pjax::begin(); ?>    
        <?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [


        ['class' => 'yii\grid\CheckboxColumn', 'checkboxOptions' => function($d) {
            return ['value' => $d['msn']];
        }],


        'ref_no',
        'dept_code:ntext',
        'dept_name:ntext',

        'allowed_units',
        'msn',

        'units_consumed',
        [
            'label' => 'Disconnected',
            'attribute' => 'disconnected',
            'format'=>'raw',
            'contentOptions' => ['style'=>'text-align:center'],
            'value' => function($model){
                return $model->disconnected == 1 ? '<span class="glyphicon glyphicon-ok text-success"></span>' : '<span class="glyphicon glyphicon-remove text-danger"></span>';
            },
            'filter' => Html::activeDropDownList($searchModel, 'disconnected', [''=>'All','1'=>'Yes','0'=>'No'], ['class' => 'form-control']),
        ],

        'diconnected_at',
        'reconnected_at',
        'active_energy_total_m',


        ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>
<?php Pjax::end(); ?>

JS

<?php

$DCOurl = Url::toRoute(['/hecolog/dco']);

$script = <<< JS
$(document).ready(function () {  



 //DCO 
 $('#dco').on('click',function(e) {


       e.preventDefault();    
 var strValue = "";        
    $('input[name="selection[]"]:checked').each(function() {

    if(strValue!=="")
        {
        strValue = strValue + " , " + this.value;

        }
    else 
       strValue = this.value;     

});       

 $.ajax({
    url: '$DCOurl',
    type: 'POST',
    dataType: 'json',
    data: {data:strValue},         
    success: function(data) {
       alert(data);
    }
 });


 });
});
JS;
$this->registerJs($script, static::POS_END);
?>

但是当我单击断开连接按钮时,它不会重定向到我的控制器。在控制台中,它给了我Not Found (#404): Page not found.

更新1

我已经更新了ajax调用,如下所示

$.ajax({
    url: $DCOurl, // removed the inverted commas ''
    type: 'POST',
    dataType: 'json',
    data: {data:strValue},         
    success: function(data) {
       alert(data);
    }
 });

控制器

 public function actionDco()
{
    if(Yii::$app->request->isAjax && Yii::$app->request->post())
    {
        $data = explode(',',$_POST['data']);

        var_dump($data);
        die();
    }
    else{
        $this->redirect('index');
    }




}

按照建议更新代码后,我可以进入控制器,但仍然无法获取数据

在控制台中,我收到错误Uncaught SyntaxError: Invalid regular expression flags

下面是我的视图的代码

我一定在做我不了解的错误

任何帮助将不胜感激。

2 个答案:

答案 0 :(得分:0)

首先url:'$DCOurl'是正确的,URL必须为单个或    双引号。因此您遇到未找到问题:

  • 您的项目是htdocs还是www,后面是/inventory-web/backend/,还是目录?您使用相对网址,因此该网址适用于例如:localhost/inventory-web/backend/web/ ...
  • ajax类型“ POST”应与behaviors ['verbs'] ['actions'](如果已设置)匹配
  • 检查控制器文件名,类名和名称空间

答案 1 :(得分:-1)

首先,如果您正在处理Ajax请求,则无法进行重定向:

  <section class="chip-area">
        <div class="container">
            <section class="chip-select-area">
                <div class="s-container">
    	            <img class="img-chip-area" src="img.png">
    	            <select class="chip-area-s"></select>
                </div>
                <div class="s-container">
	                <img class="img-chip-area" src="img.png">
	                <select class="chip-area-s"></select>
                </div>
	            <div class="s-container">
	                <img class="img-chip-area" src="img.png">
	                <select class="chip-area-s"></select>
	             </div>
	             <div class="s-container">
	                 <img class="img-chip-area" src="img.png">
	                 <select class="chip-area-s"></select>
	             </div>
            </section>
            <section class="stage-select-area">				
            </section>
        </div>
    </section>

关于JS错误,而不是:

public function actionDco()
{
    Yii::$app->response->format = Response::FORMAT_JSON;
    $rv=[];
    if(Yii::$app->request->isAjax && Yii::$app->request->post())
    {
        $data = explode(',',$_POST['data']);

        $rv["infos"]=$data;
        $rv["status"]='gotData';
    }
    else{
        $rv["url"]=Url::to('index');
        $rv["status"]='redirect';

    }
    return $rv;
}

$.ajax({ url: $DCOurl, type: 'POST', dataType: 'json', data: {data:strValue}, success: function(data) { alert(data); } }); 周围添加引号,并管理ajax调用的返回值

$DCOurl
