document.write problems

[Russell Quinn]

hi there,

I am trying to use document.write to write an event handler, but all
I get is syntax errors..(this is all on one line)

document.write( '<a href="#" onClick="jkpopi mage("'+imageFi leName+'",
"'+imageText+'" ); return false"><img src="'+thumbFil eName+'" width="50"
height="50" border="1"></a>');

The actual error is the first occurance of >... anyone shed any light on
this?

Thanks,

Russell

The more likely error is that you didn't escape the forward slash:

'...</a>'); should be '...<\/a>');

Other than that, the statement is fine. The only other possible
problem would be that the jkpopimage() function isn't defined, but
you'll have to check that.

When do you get syntax errors? When calling document.write, or when
calling the event handler?

What, *exactly*, are the contents of imageFileName and imageText?

What is the error message?
Which browser do you use?
(And can we see the rest of the page?)

Did not use this trick for a while, but I remember some security
limitations on JavaScript via write() method. In 4th versions it did no
work (was not forwarded to the script interpreter), that was the time I
dropped it, I'm wondering about now.

I had a play and found that IE6 reported a syntax error on running the
script but Mozilla and Opera were happy. The location of the error wasn't
usefully reported. However what IE really seemed to be unhappy about that
the code actually wrote (with invented contents of the variables)...

<a href="#" onClick="jkpopi mage("filename. jpg","some text"); return false">

....and you can see that the onClick code is delimited by double quotes but
also has them in the contents. Changing the delimiting quotes to \' made IE
happy.

thanks for all the comments, i eventually worked it out later... it was the above
suggestion that I had the function parameters delimited by the same method
as the onClick handler :o(
