$(#txt).focus() function() {
// this is when the user tabs to the control or clicks on it
});
$(#txt).blur() function() {
// when the user tabs out or clicks on something else
});
if you check the JQuery events page you will other helpful event
like :
keyup
keydown
mouseup
mousedown
you can usually detect input change on key up event
var txt = $(#myid).text();
$(#myid).keyup(function() {
if(txt != $(this),val() {
txt = $(this).val();
alert(input changed)l
}
}
});
so a script for your solution would be
$(#source).keyup(function() {
$(#target).attr{(
value: $(#source).attr(value)
});
});

Assuming the second input field is triggered by a user instigated event,
then you could just trigger that event.
$('input#change').click(function() {
$('input#source').attr('value', 'This is the value changed by a
button');
$('something').trigger('blur',fn);
});

Subject: [jQuery] How to simulate a human-triggered event?
Hi, I'm trying to change the value of an input field (target) which depends
on another input (source). It works well when I manually change the source
value. But if I changed the source value with another button, the target
value remains the same. Here's the code...
$(document).ready(function() {
$('input#change').click(function() {
$('input#source').attr('value', 'This is the value changed
by a button');
});
$('input#source').change(function() {
$('input#target').attr('value',
$('input#source').attr('value'));
});
});
pSource: input type=text name=target id=source size=60
value= / input type=button id=change value=change source value
//p
pTarget: input type=text name=target id=target size=60
value=This is the original value, type something in source to change
//p
So how could the target input detect if there's a change within the source
input without manually changing it's value? Thanks
