In a PHP, there's a form that sends a variable to the same page. 
I want to make a jQuery that shows/hides a specific div (using ID); if the value is sent (the form is sent to the same page), I want to show the div

in the PHP file, I have this form:

```
<form action="<?=$_SERVER['PHP_SELF'];?>" method="get">
<input type="hidden" name="status" value="12345">
<input type="submit">
</form>

```

in the linked js file, 
How can I detect the hidden value "status" is sent? and if the $\_GET["status"] is not NULL,
I want to show $('specificID').show();, which was originally:

```
$(document).ready(function (){
 $('#specificID').hide();
}

```

Thanks.
