Javascript defaultValue

For some reason I have never needed to use the defautlValue property up until today.  I was pleased to find javascript can access the original input value so tracking changes in a form is a bit easier.  However, the defaultValue only works as expected for “text”, “file”, and “password” fields.

A workaround is to use type=”text” and just have a style=”display:none;” to act like a hidden field.
