Preserved Topic: Preloading images (Page 1 of 1)

yes... me again :S
im trying to preload some images so they dont flash when the onclick event is called
preloadint the pic:
var p1=new Image();
p1.src='1.jpg';

the function:
function cambia(what)
{
if (what==1)
{
document.getElementById('pic').src ="'+p1+'";
}
}

the tag:
<td class="h" id="17"><img src="5p.jpg" onClick="cambia(5)"></td>

This is mostly a string problem.

Remember that double quotes and single quotes don't match each other. When you set the source to "'+p1.src+'", you're setting it to

'+p1.src+'

since there are no double quotes inside your double-quoted string. And since there are no images called '+p1.src+' anywhere, it can't load the image.

Here's what you want to do. You want the source to be p1.src, so merely set it like this:

document.getElementById('pic').src = p1.src;

It seems that what you're trying to do right now is set it to "" + p1.src + "", but adding those extra empty strings on either side is unecessary. Because they're empty.

Now, you also have to set id="pic" inside your image tag for that to reference the correct element. And also, your function tests if(what == 1), and you're calling it as cambia(5). You'll either need to change the 1 to a 5, or the 5 to a 1. If they don't match, the function won't do anything.

Thanks again slime

actually i have several images 1,2,3 and so on but i pasted the wrong tag :S (thats why u saw a function with a wrong parameter #)

Thanks, merci, gracias .
