PHP session id to Javascript in Internet Explorer

[tmk4php]

Hi,

 

I'm trying to pass a PHP variable holding a session ID to Javascript.  I've gotten it to work successfully in every browser except Internet Explorer (I've only tested in IE7 and IE8beta, nothing earlier) by passing it through a hidden input field.  Here is the code:

 

  <input type="hidden" id="dataxml" value="<?php echo $xmlsheet; ?>">

</form>

  <script type="text/javascript"> 

    //other code

    myChart.setDataURL("temp/Data_" + dataxml.value);

  </script> 

 

$xmlsheet is holding the session ID.  IE gives me an error saying that my 'dataxml' is undefined.

 

Does anyone know why IE is throwing this error, or any way around it?  Right now I'm just telling users not to use IE...

what happens if you change

myChart.setDataURL("temp/Data_" + dataxml.value);

to

myChart.setDataURL("temp/Data_" + document.getElementById('dataxml').value);

 

or possibly

myChart.setDataURL("temp/Data_<?php echo $xmlsheet; ?>");

CroNiX probably nailed it!   (i woulda said the same thing but im cool because i use jQuery so it would be $('#dataxml').val(); ) 

 

Although i'm baffled as to how it works in all other browsers...????  ???

bleh...jquery...use mootools   A lot smaller, more functions, and better smoother animation.

CroNiX - you definitely nailed it!  getElementById was the answer, and it now works in all browsers.

 

Many thanks!!!

Sure, actually Im surprised it worked in the other browsers the way you had it.

ditto.  (i know i already said it). but still... wow!  (no offence to OP) but i just didn't realize this was even possible!!!  :o

My how browsers are making it easy to make mistakes by not being strict enough...I can't believe that IE of all things was the app that caught it.
