Converting Html Table to JSON. Ask Question up vote 6 down vote favorite. I've created a sample application which converts html table into JSON. The problem is.
You cannot serialize a table - that method doesn't apply to that kind of DOM object, only forms and form fields can be serialized. If you really want to do what you're proposing, you need the proper selector to pick just the children of tbl2 that are also form elements, and then you'll have to serialize each one of those by hand. Someone did it in another question, here: a better way might be to disable all the form elements that are NOT in the table you're interested in - you'll need a selector to pick all form elements that are not child elements of tbl2 - and THEN serialize the form. The disabled elements will be omitted.
