javascript and struts

[Will Spies/Towers Perrin]

I have some HTML tags that have struts form data associated with them of
the form <input name="data.value">. For example: <input name
="data.employeeName"></input>. I seem to be having difficult referencing
these in Javascript due to the ".'. Javascript thinks employeeName is a
property of data rather than both being one single variable name. Anyone
else run into this or am I barking up the wrong tree?
