.val() doesn't fire change Event

[toxcct]

Hello,

I just noticed that using .val() on a form field (text field) doesn't execute the "OnChange" event handler binded on that Field...

Also, the .val() documantation page ( http://api.jquery.com/val/ ) doesn't mention anything about this, so I suspect this to be a bug.

Can you tell if this is a desired behavior or not ?
Must I say that I'm using jQuery 1.8.2.

Thanks.

This is not a bug, this is just how the event model works. If you edit .value on an input, it doesn't fire change. It might be useful to mention this in the documentation page, but this is definitely the "expected behavior"

Draft Wording:

When setting values using .val( newValue ) it is important to note that it will not fire any bound change events. If you want to fire these events, you should .trigger( "change" ) after setting the new value.

Assigning to the DOM .value property doesn't fire a change event either, so this isn't specific to jQuery and doesn't need jQuery documentation.

Taking into account amount of similar StackOverflow questions, it still may have sense to clarify this subtle point in jQuery documentation.
