问题
I'm trying to get productname,productiondate and prodqty from production model in gridview and also the sum(prodqty) in a textbox when a particular product is selected. The gridview is populating fine. I can see the sum(prodqty) javascript alert in a flash. But it's not passing to the textbox. The error message is - uncaught exception: unknown (can't convert to string) Again if I comment out the code for the gridview, the sum(prodqty) is shown in the textbox but I don't get the gridview.
My Controller Actions -
public function actionIndex()
{
$catId = yii::$app->request->get('catId');
$searchModel = new ProductionSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams, $catId);
$searchModel2 = new ProductsalesSearch();
$dataProvider2 = $searchModel2->search(Yii::$app->request->queryParams, $catId);
$model = new Productnames();
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
'searchModel2' => $searchModel2,
'dataProvider2' => $dataProvider2,
'model' => $model,
]);
}
public function actionGetForProduction($catid)
{
$production = Production::find()->select('sum(prodqty) as totalproduction')->where(['productname'=>$catid])->asArray()->one();
echo Json::encode($production);
}
Javascript code in index.php -
<?php
/* start getting the textboxes */
$script = <<< JS
$(function(){
$('#catid').change(function(){
getIndexpage();
getTotalproduction();
});
var catid = $(this).val();
var getIndexpage = function(){
var catid = String($('#catid').val());
window.location = 'index.php?r=productstockbook/production/index&catId='+catid;
} ;
var getTotalproduction = function(){
var catid = String($('#catid').val());
$.get('index.php?r=productstockbook/production/get-for-production',{ catid : catid }, function(data){
alert(data);
var data = $.parseJSON(data);
$('#production').attr('value',data.totalproduction);
});
} ;
});
JS;
$this->registerJs($script);
/* end getting the textboxes */
?>
The error screenshot -
What happens if I comment out the window.location code - Code -
<?php
/* start getting the textboxes */
$script = <<< JS
$(function(){
$('#catid').change(function(){
getIndexpage();
getTotalproduction();
});
var catid = $(this).val();
var getIndexpage = function(){
var catid = String($('#catid').val());
//window.location = 'index.php?r=productstockbook/production/index&catId='+catid;
} ;
var getTotalproduction = function(){
var catid = String($('#catid').val());
$.get('index.php?r=productstockbook/production/get-for-production',{ catid : catid }, function(data){
alert(data);
var data = $.parseJSON(data);
$('#production').attr('value',data.totalproduction);
});
} ;
});
JS;
$this->registerJs($script);
/* end getting the textboxes */
?>
Screenshot if I comment out window.location code -
We can see that the alert is staying but the gridview is obviously not populating.

Update -
I got that after window.location the page is redirected to a new page and all the javascript code after new page load should be written in the new page. Please let me know how to write codes in the new file. As this page is loaded dynamically I'm not so sure where to call the javascript functions.
