I'm trying to create a javascript function that calls a php page ajax style and unhides the table row that contains it. When the user hides the row again and then unhides it again after that, it would be awesome if the javascript already knew that it has been called and only shows the row instead of reloading it.

 

any ideas?

once you have retrieved a row, just store some info in an array that identifies that row as already loaded:

rowsloaded[] = 'id number or other identifier'; //adds new element at end of array

--before you ajax, search the rowsloaded[] array for the row
