收集未提交的表单值

Is it possible to capture data from an abandoned form?

ex:

Name: Jim Hancock Address: 1223 Fruitville Dr. Phone: 845-525-1156 Email: Jim.c

(Submit Button)

In the above example: Without having the submit button clicked the user would either navigate to another page or close the browser altogether and now I have no data, when in fact the person was 75% through completing the form...

Any ideas or is this type of thing not allowed?

This type of thing can be done with ajax. Every so often, just submit what form data they have through an ajax request. How to store that and how to implement such a system are outside the bounds of a simple question such as this. But it can be done.

you don't want to keep all your unsubmitted forms in your database. instead use javascript and cookies. Take a look at the javascript library: Garlic.js
