Attribute of textbox - read only?

Is is possible to create a text attribute and then set the text box become "read-only"?

I have a JavaScript that auto populates the text area of a current attribute... works like a champ! Problem is that I created the JavaScript due to the customer occasionally puts in the wrong info even after my fancy code inputs the correct info. They manually overwrite what was put into the text box by the code then type in something new. *example: another child's name (*one not on the list)

I was hopping that I could make the textbox readonly.

I didn't see that option in the attributes controller in the CP.

Example: http://www.justmymusic.com/store/index.php?main_page=product_music_info&cPath=1&products_id=1
(*I am only testing this on my weakest selling product) I know... testing on a live site... naughty naughty! :blush:

Found the answer... well via JavaScript:

Just in case somebody stumbles upon this thread:

document.getElementById("attrib-1-0").readOnly=true

Where exactly do you place this command?

CREEPUR:

Where exactly do you place this command?

*I sell music related products so I put it into tpl_product_music_info_display.php

Where as most would probably put it into: tpl_product_info_display.php

Path: /store/includes/templates/YOURTEMPLATE/template/tpl_product_info_display.php

Hope that helps!
