The system asks the user to identify the number of records they would like to enter, based on their selection (say 3), the system displays three text boxes.
<?php for($i=1; $i<=$rows; $i++) { ?> // $i is 3 here
<input type="text" name="company_name[]" id="cn[]">
<input type="text" size="3"name="entertainment[]" id="en[]">
<?php } ?>
So this will generate 3 rows, with the same text boxes. If the user enters a value in the 1st row for entertainment, the company name should get grayed out or vice versa. Similarly it should do the same for the 2nd and 3rd line as well - based on which text box they fill.
How do I do that via js/jquery?
P.S: I am not a good front-end developer, so I could use all the help I can get.
Thanks.
