Question

I’ve got a form with several search (text) fields. When text is entered into one of the fields, I’d like to disable the others. Conversely, if all text is removed from the active text field, the other fields should be re-enabled.

The basic idea would be something like this (I think):

$(document).ready(function() {     $('input[@type=text]').keypress(function(e) {         if(current textbox has text in it)         {             //disable all textboxes that aren't this one         }         else         {             //enable all textboxes         }     }); }); 

I’m not clear on what the easiest way to find/work with ‘all text boxes that aren’t this one’ is.

Answer 1

I think the best way to do ‘all textboxes that aren’t this one’ is using the not filter like:

$(document).ready(function() {     $(':text').keyup(function(e) {         if($(this).val() != '') {             $(':text').not(this).attr('disabled','disabled');         } else {             $(':text').removeAttr('disabled');         }     }); }); 

Couple notes:

• I recommend giving a class to all the input elements you want to include with this behavior and doing a selector of input.myfields as it is faster/cleaner.
• Also, as of jQuery 1.3, the @ in the selector is not supported. :text is shorthand for what you want, if are you sticking to selecting them that way.
• I also think you want the keyup event instead of keypress.
