how to refresh particular element in php with jquery? - php

Question

I have one select box.on change event of it, I call confirm box. When I clicked on cancel button then remains changed value.
So I want to refresh only select box not whole page.
function statusChanged(obj,id){
$(obj).change(function() {
var answer = confirm ("Are you sure update Status?");
var status;
if(answer){
status=$(this).val();
//alert(status);
ajaxUpdate("service-providers.php", {action:"updatestatus",'status': status,'id':id}, function(data) {
if(data.type=="success") {
$("#notify").notification({caption:"Status Updated Successfully.", type:"information", sticky:false ,onhide:function(){
window.location="service-providers.php";
}
});
}
});
}
else{
// here i want to refresh select box
}
});
}
html code:
<select id="status1" name="status1" style="width:140px;" onChange="statusChanged(this,<?php echo $applicationid; ?>);">
<?php
if($status==3 || $status==4)
echo "<option value='4'>Submitted</option>";
else
echo "<option value='0'>Select</option>";
?>
<option value="2" <?php if($status==2) echo "selected='selected'"; ?> >Approved</option>
<option value="3" <?php if($status==3) echo "selected='selected'"; ?> >Rejected</option>
</select>

Answer 1

after page loads do:
$('select').each(function() {
$(this).attr('original_data', $(this).val());
});
and in your function do
$(this).val(this.attr('original_data'));
Checked. Works perfectly.

Answer 2

use this code under else it will just reset select box.
This will work
$('#SELECTBOX_ID').prop('selectedIndex',0);
see the for http://jsfiddle.net/TmJCE/10/ working demo.
also I implemented this code in my local I mainly made two changes I removed onchange from select and second is I did not use ajax coz you only want to work on click of cancel on confirm box.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
jQuery(document).ready(function () {
jQuery("#status1").change(function() {
var answer = confirm ("Are you sure update Status?");
var status;
if(answer){
status=$(this).val();
//I have did not call ajax
}
else{
jQuery('#status1').prop('selectedIndex',0);
}
});
});
</script>
<?php
$status = 0; // I temporary added t
?>
<select id="status1" name="status1" style="width:140px;" >
<?php
if($status==3 || $status==4)
echo "<option value='4'>Submitted</option>";
else
echo "<option value='0'>Select</option>";
?>
<option value="2" <?php if($status==2) echo "selected='selected'"; ?> >Approved</option>
<option value="3" <?php if($status==3) echo "selected='selected'"; ?> >Rejected</option>
</select>
