Hello-

I’d like to throw a little AJAX into a table to allow the user to edit a  
single row of data inline rather than moving to another page.

The row (which has N columns) would be swapped out for a row which has a  
single column (colspan=“N”) and the form inputs would be in that row.

My question is, is this legal HTML? I can’t find anything that says  
either way. Basically, I’m thinking the HTML would look like:

…

 blah blah

 blah blah
...

During the AJAX call, “item\_44” would get replaced with something like:

...Edit Blah...

Is this ok?

Jake

Hi Jake,

Just add the id to the … so

 Whatever Whatever

You should not use

's when you don’t need to. Always try to use a  
already existing tag before resorting to a div.

Thanks. This is what I was after. Though, for this particular case,  
the ID’ed will work just fine.

Thanks!

Also, for the record, adding a div inside a tr directly is against XHTML  
standard  
([http://learningforlife.fsu.edu/webmaster/references/xhtml/tags/table/tr.cfm](http://learningforlife.fsu.edu/webmaster/references/xhtml/tags/table/tr.cfm)).
