[jQuery] Re: How to simulate a human-triggered event?

[Andy Matthews]

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'));
        });
});

<p>Source: <input type="text" name="target" id="source" size="60"
value="" /> <input type="button" id="change" value="change source value"
/></p>
<p>Target: <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
