We may need to enable or disable a text box based on the input of the user by using disabled property of the element. For example we have some choices for the visitor and one of the options is Others. Once the visitor select the others options then ( only ) one text box will be enabled to allow the visitor to fill the details.
I found everywhere this one.finally i found this by in this site.very simple and useful.good job.thank you.good luck.

This works as described, but what if I want to have multiple disabled text fields linked to multiple checkboxes? The result for me is that checking ONE box enables ALL the text fields, but I would like it to only enable the one. Any ideas? Thanks!

You can read how to disable submit button till all the inputs are validated. You can add one more condition to it. But if you take JavaScript client date then that can be changed by user so you have to match with server side date.

You can choose 2 step
step 1 set onload=enable_text(false);
step 2 not set onload=enable_text(false);
and set textbox to diasable
Ex. <input type=text name=other_text diasabled>
