问题描述
我正在研究Yii2.我有一个带有复选框的gridview，并单击一个按钮，我正在使用ajax将其重定向到动作控制器.
I am working on Yii2. I have a gridview with checkbox and on a button click I am redirecting it to an action controller using ajax.
<?= 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.
But when I click on the disconnect button it doesn't redirect to my controller. In console it gives me Not Found (#404): Page not found.
更新1
我已经更新了ajax调用，如下所示
I have updated the ajax call like below
$.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
After updating the code as suggested I am able to go into my controller but still not able to get the data
在控制台中出现错误Uncaught SyntaxError: Invalid regular expression flags
更新2
下面是我的视图的代码
<?php
use yii\helpers\Html;
use yii\grid\GridView;
use yii\widgets\Pjax;
use yii\helpers\Url;
use yii\web\JqueryAsset;
/* @var $this yii\web\View */
/* @var $searchModel common\models\HescologSearch */
/* @var $dataProvider yii\data\ActiveDataProvider */
$this->title = 'DCO / RCO';
$this->params['breadcrumbs'][] = $this->title;
?>
<section class="content-header">
<h1>DCO / RCO List</h1>
</section>
<section class="content">
<div class="box">
<div class="box-body">
<p>
<?= Html::a('Disconnect', ['dco'], ['class' => 'btn btn-success', 'id'=>'dco']) ?>
<?= Html::a('Re-Disconnect', ['rco'], ['class' => 'btn btn-info','id'=>'rco']) ?>
</p>
<?php Pjax::begin(); ?>
<div class="pre-scrollable">
<?= 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'],
],
]); ?>
</div>
<?php Pjax::end(); ?>
</div>
</div>
</section>
<?php
$DCOurl = Url::toRoute(['/hescolog/dco']);
$RCOurl = Url::toRoute(['/hescolog/rco']);
$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);
}
});
});
$('#rco').on('click',function(e) {
e.preventDefault();
var strValue = "";
$('input[name="selection[]"]:checked').each(function() {
if(strValue!=="")
{
strValue = strValue + " , " + this.value;
}
else
strValue = this.value;
});
$.ajax({
url: '$RCOurl',
type: 'POST',
dataType: 'json',
data: {data:strValue},
success: function(data) {
alert(data);
}
});
});
});
JS;
$this->registerJs($script, static::POS_END);
?>
我一定在做我不理解的错误
I must be doing something wrong which I am not understanding
任何帮助将不胜感激.
Any help would be highly appreciated.
推荐答案
首先url:'$DCOurl'是正确的，并且url必须为单个或
双引号.因此您遇到一个未找到问题:
first of all url:'$DCOurl' is correct and url must be in single or
double quotation. so you have a not found problem:
- 您的项目是htdocs还是www，然后是
/inventory-web/backend/?还是还有其他目录?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"(如果已设置)应与behaviors ['verbs'] ['actions']相匹配
- 检查控制器文件名，类名和名称空间
- is your project in htdocs or www followed by
/inventory-web/backend/or there are some more directories? you use relative url so the url would be for ex:localhost/inventory-web/backend/web/ ... - ajax type 'POST' should match with behaviors['verbs']['actions'] if you have set it
- check controller file name, class name and namespace
