Get Form Field Value
Returns a form field's value. The field is looked up in the active tab of the frontmost window of the selected browser.
For most form field types, the contents of the
value attribute will be returned.
For radio buttons, it'll be the value of the selected one of the radio set.
For checkboxes, either "checked" or "unchecked".
Field name selection strategy
Fields can be looked up by their
name attribute, their
id attribute, or by CSS Selector.
Depending on the selected Field name selection strategy, specify either the
name attribute, the
id attribute, or a CSS Selector.
All bets are off for form fields holding file references, I've yet to test them. 😉
