Ajax call not displaying message properly using Yii framework - php

Question

So here's the problem:
Trying to make an ajax call using .ajax. However, there's something going wrong somewhere because my controller isn't redirecting to the good view file and nothing is displaying on my page.
Here is where the ajax call happens
$('#validate').on('click',function(){
var data = []; // data container
// collect all the checked checkboxes and their associated attributes
$("table#subsection_table input[type='checkbox']:checked").each(function(){
data.push({
subsectionid : $(this).val(),
sectionid : $(this).data('sectionid'),
year : $(this).data('year')
})
});
// JSON it so that it can be passed via Ajax call to a php page
var data = JSON.stringify(data);
$.ajax({
url : "<?php echo Yii::app()->createAbsoluteUrl("scheduler/AjaxExample"); ?>",
type: "POST",
data : "myData=" + data,
success : function()
{
alert("in success");
$("#ajax-results").html(data);
$("#ajax-results").dialog({ width: 500, height: 500})
},
error: function()
{
alert("there was an error")
}
})
console.log(JSON.stringify(data));
$('#dialog').html(data).dialog({ width: 500, heigh: 500});
});
Now here's my controller code:
public function actionAjaxExample()
{
$post_data = $_POST['myData'];
$this->renderPartial('_ajax', array(
'data'=> $post_data,
)
);
}
trying to redirect to _ajax view file:
<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
echo "HI FROM BACKEND! here's what you gave to PHP: <br>";
print_r($data);
?>
So I'm obviously doing something wrong but... I can't seem to find where because the ajax call DOES happen ( at least in my #validate on click event). However, the last view file isn't displaying it's alert box OR the "hello from back end".

Answer 1

Try :
remove var data = JSON.stringify(data);
change
data:{myData:data},

Answer 2

I think the issue is with the quotes of the url.
Please check if you are getting some JavaScript error in console.
If you are getting some error, Please change this
$.ajax({
url : "<?php echo Yii::app()->createAbsoluteUrl("scheduler/AjaxExample"); ?>",
type: "POST",
to
$.ajax({
url : '<?php echo Yii::app()->createAbsoluteUrl("scheduler/AjaxExample"); ?>',
type: "POST",
If not getting any error, Please check the xHr tab in console, whats the url, your ajax is hitting. Please let me know in case of any issue
