changing image source

[david.sargent]

ok, I am just learning this stuff, small stupid question here...I am
trying to swap images in a little ajax application, and the code
handling that looks like...


document.placeholder.src =xmlHttp.responseText


/
no big deal i know, if i print xmlHttp.responseText to the screen the
link is correct, but anytime I assign it as a src, i get the link+(all
the page html attached on the end) and i dont know why?

this is driving me crazy

I hope placeholder is an image tag....

document.images['placeholder'].src is less ambiguous.

What "link" is correct? Are you trying to create a link or change an image?

but anytime I assign it as a src, i get the link+(all
the page html attached on the end) and i dont know why?

Problably something in the responseText doesn't close a tag. Or,
something else is screwing it up.

Post a sample page URL that has your code in it.

ok, since this is a little ajax thing, i have it handling the response
like this

function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.images['placeholder'].src =xmlHttp.responseText
}
}

now, if i change it to write a message based on the xml response, it
displays like it should, only with the image it screws up...

if i just do document.write(xmlHttp.responseText) it prints out:

http://static.flickr.com/48/131196335_d17ea359ff_s.jpg ----> THIS IS
CORRECT


http://static.flickr.com/48/1311963... <div> </div> </form></body></html>

---->this is not...


what is happening?

Off the top of my head, try:
document.images['placeholder'].src=xmlHttp.responseText.toString();

that didnt seem to do it...i am really confused by this, it will print
out the string fine, but as soon as I try to assing the URL to a photo
as its source, it gets jumbled...

I will refrain from repeating what Evertjan said about quoting, but
please don't top post either.

Try setting a variable to the responseText, alert that responseText, and
then set the src to the variable:

myVar = xmlHttp.responseText;
alert(myVar);
alert('typeof myVar is ' + typeof(myVar));
alert('typeof xmlHttp.responseText is ' + typeof(xmlHttp.responseText));

What do the two typeof's give you?

Both say typeof string, but when the alert(myVar) pops up, it shows the
additional text on the end...when I just do a
document.write(xmlHttp.responseText) it gives me just the url...

That be as it is,
but comp.lang.javascript is NOT a Google group,
it is a Usenet goup.

Google is only the portal you use.

Better use a dedicated news-reader.
