Below is what I have build with several different languages. It works great but I need help, I am stuck.
When you click on an item in the dropdown autocomplete div it does a mousedown function and send the item number to the xmlHttp and works awesome. Now I need to add an apply button next to it. so they can type in the complete number then hit apply and it does the same function. I cant get it to work with the script I have. The image is apply where I am trying to get this to work.
you can see an example of this at http://www.wrighter.com/music/autocomplete.cfm
AutoComplete.prototype.onDivMouseDown = function() does the action to xmlHttp call and sending the div info.
I cant get it to take the info from the field and do the same thing. help!
