dwr.util.getValue(id) is the read version of setValue(). This gets the values out of the HTML elements without you needing to worry about how a selection list differs from a div.
This method works for most HTML elements including selects (where the option with a matching value and not text is selected), input elements (including textareas) divs and spans.
For example:
dwr.util.getValue(
)
Returns " " (Press 'getValue').
