control & submits the page it alerts the message of javascript but

postback .

Yes. It sounds like you are doing a form validation, however on
invalid entry, you are failing to stop the form submission. In that
case, you can do something like the following:

html:

<form onsubmit = "return validateForm(this)">
....your form elements...
<input type = "text" name = "userdate">
</form>

javascript:

function validateForm(myForm)
{
/*your validation routine
.
.
.
*/
if(myForm.elements["userdate"] == "some_value")
{
return true;
}

return false; //for invalid entry return false, for valid entry
return true
}

.
