[SOLVED] trying to unhide div with xml file variable

[c_shelswell]

Hi

 

I've got a little bit of ajax happening that gets a mails "read" status from a mysql database. I'm then exporting an xml file of the data to read back in with javascript.

 

This bit all seems to be fine. The problem i'm having is with the imported xml data i need to hide or unhide a div

 

i've got divs on the page that look like

<div id='readMail39' style='display:none'>

 

the javascript code i've got is

var mId = xmlDoc.getElementsByTagName("email") //<< MAIL ID AND STATUS	
var numMails = xmlDoc.getElementsByTagName('email').length //NUMBER OF EMAILS
var mNum;

for (i=0;i<numMails;i++)
{
	mNum = mId[1].childNodes[0].nodeValue;

	if (mId[i].childNodes[1].lastChild.nodeValue == 0)
	{
		document.getElementById('readMail'+mNum).style.display = 'none';
		document.getElementById('unreadMail'+mNum).style.display = 'block';
	}
	else
	{
		document.getElementById('readMail'+mNum).style.display = 'block';
		document.getElementById('unreadMail'+mNum).style.display = 'none';
	}
}

 

i think it's the "mNum" variable that keeps messing things up as i keep getting the error:

 

Error: document.getElementById("readMail" + mNum) has no properties

 

if i try and cheat it however by just changing to display ='block' line to

 

document.getElementById('readMail39').style.display = 'block';

 

it works fine. what am i getting so wrong????

my xml is

<mail>
<email>
40
<status>1</status>
</email>
<email>
38
<status>0</status>
</email>
<email>
39
<status>0</status>
</email>
<email>
41
<status>1</status>
</email>
</mail>

 

any ideas on this would be amazing

Thank you

SOLVED!!

 

This took a while - i just needed to parse it as an integer

 

mNum = mId.childNodes[0].nodeValue;

pointValue_n = parseInt(mNum,10);
