HTMLHelp Forums _ Client-side Scripting _ variable in < OBJECT

Posted by: crlx2 Feb 4 2020, 06:34 PM

i need to show the text contained in a text file, so i used this html line:

<object id="file1" data="file1.txt"></object>

what i am not able to do is: how to use a variable instead of the string "file1.txt" ?

thanks

I think you could change the value of the DATA attribute with e.g.:

CODE

<button onclick="document.getElementById('file1').setAttribute('data','file2.txt');">...

but Firefox appears to be buggy.

Dear Chistian J
i was not able to let it work (in chrome)
on setattribute i get an error: TypeError: Cannot read property 'setAttribute' of null

Could you post a sample of it?

Another solution might be to use server-side scripting (e.g. PHP) to read the text file, then browser support isn't an issue.
