insert text into textarea when option selected

Question

I need your help. I'm trying to insert some text into a textarea-element when the url contains 'number' and an option with value='option2' of a selectbox is selected.

 var contentToInsert = 'Text'; if (location.href.indexOf("/number")) { if (value of selectbox == 'option2') { $("textarea").append(contentToInsert); } }

How do I check when the option is selected? The text to insert shouldn't be shown when another option is selected. So this would mean that I need on event-handler like onchange.

Have you got an idea?

jQuery .change() event exists :

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

Thy with something like that :

Are you sure this line of your code is right?

$("textarea").append(contentToInsert);

If you are referring to a tag with the id "textarea" then maybe it should be:

$("#textarea").append(contentToInsert);

Not to mention this will append to that id tag a child node.

Hope it helps :) Cheers!

Hi, well. I can use both. The id and the element. Thank you for the note.

Ah ... I see you're using the tag itself. Hm ... does it work already?

It works but all the textarea will be filled with the value of contentToInsert.
