Do that with JavaScript.[html]<input type="text" name="phone" id="ph" onkeyup="docume nt.getElementBy Id('ac').disabl ed = !!this.value.le ngth;">
<input type="text" name="account" id="ac" onkeyup="docume nt.getElementBy Id('ph').disabl ed = !!this.value.le ngth;">[/html]

This is a JS question and belongs in the JavaScript forum, so I will move it to that.

You mean the double NOT?
It will work without the double NOT too. Its not mandatory.

Double NOT just makes sure the result is boolean.
!!0 returns false
!!n returns true (where n is any number)
Also works on strings.

Thanks for the response.
But its not working on single not.
if the purpose of its to set a boolean value then
why its not working in like below.

<input type="text" name="phone" id="ph" onkeyup="docume nt.getElementBy Id('ac').disabl ed = true;">
<input type="text" name="account" id="ac" onkeyup="docume nt.getElementBy Id('ph').disabl ed = true;">

What are you trying to do? What is the purpose?

If you got a similar problem, tell me that.

HI,
call the javascript function for both textboxes...lik e,

txtDayphone.Attributes.Add("Onkeypress", "return formatPhoneNumber(this)")

and check there if one of the textbox gets keypress at the same time remaining text box gets disable to data entry...... i think by implementing this your problem will be solved...

...

this is no javascript-code ... it seems to be some .NET stuff ... please don't mess different things here ... to set an attribute to a node the regular javascript-dom-method is:

node.setAttribute('attrib_name', 'attrib_value');

to attach event-handlers you have different possibilities ... write it to the node directly:

[HTML]<input type="button" onclick="alert( 'clicked me');" value="click me"/>[/HTML]
or use addEventListene r() and attachEvent() for this, or set the event-handler-properties like:

node.onclick = function() { alert('something') };

and: Use code tags when posting Source Code!!!!!

kind regards
