Flagging the changed input field

[ids]

Is there a way to flag which input field was changed? I am guessing it would have to be some JS?

System_content, displaying table data, so rows and columns. Rows are grouped together, so when I need to change a value, all the rows in a group are enabled with an INPUT field. The problem is when I am looping through the array structure when passed to _Validate or _Update, I need to know which field had been changed.

Just to create a picture, if needed, imagine 3 rows of 3 columns of values, a button is clicked and the table turns into 9 text input fields. If I change the value in row 2 col 3, I need that field flagged so I can do something when I reach that position in the loop.

Thanks,

Scott

In cases like that, I generally create a hidden field for each input, to save the previous value. Then in my Module_XXX_Update function, I compare the old values to the new ones. Kind of a brute-force solution, but it works, and it doesn't require any Javascript.

I'll give that a whirl, Thanks Kent.
