Hidden Values in Forms

How can I post a form that contains a hidden value in the JSON? Similar to passing

<input type='hidden' name='someName' value='someValue'/>

Sorry I put some HTML that didn’t come through. I was talking about passing the equivalent of < input type=hidden />

You can add any information to the hash of form values with the help of
setValues method.

//reset values
form.setValues({a:"b"});

//extend form values with new  "name:value" pair
form.setValues({a:"b"}, true)

These values will be returned by form.getValues() method.
