[SOLVED] preloader function help

[jdubwelch]

i have 32 images in a folder.  they're named: 0.gif, 1.gif, 2.gif,..., 30.gif, 31.gif

 

I want to preload all those images.  Preloader is my function that doesn't work and makes my other function "setWinner" to not work.

 

   <script language="JavaScript" type="text/javascript">
<!--
function setWinner(clickedObjId,row)
{

	document.getElementById('row'+row).innerHTML = '<div align="center"><img src="team_logos/' + clickedObjId + '.gif" width="80" height="80" /></div>';
	document.getElementById('winner'+row).value = clickedObjId;

}

function preloader () {

	imageObj = new Image();

	for(var i=0, i<=31; i++) 
	{
		imageObj.src = 'team_logos/' + i + '.gif';
	}

}

// -->
</script>

row is outside the scope of document.getElementById; that's why you first function isn't working.

What does that mean? How do i fix it?

try this and see if it correct the issue:

 

   <script language="JavaScript" type="text/javascript">
<!--
function setWinner(clickedObjId,row)
{

	document.getElementById('row'+row+'').innerHTML = '<div align="center"><img src="team_logos/' + clickedObjId + '.gif" width="80" height="80" /></div>';
	document.getElementById('winner'+row+'').value = clickedObjId;

}

function preloader () {

	imageObj = new Image();

	for(var i=0, i<=31; i++) 
	{
		imageObj.src = 'team_logos/' + i + '.gif';
	}

}

// -->
</script>

It didn't work.

You're using a "," comma in your for statment where is suppose to be a ";" semicolen

 

this

for(var i=0, i<=31; i++)

 

should be

for(var i=0; i<=31; i++)

auh - I didn't catch that - good eye nogray

[jdubwelch]

thanks.  Is there anything for javascript that will point the errors out like php does?  Php tells you which line your error is on and makes it a little easier if you happen to have a ',' instead of a ';'

download FireBug for FireFox - it is a add-on and it will help you find your errors. if I had tested your code in FireBug; I would have caught your error - just a visual over look on my end.
