Using jquery to prevent resubmitting form

Question

I use jquery's .submit() to intercept user's submit event, however I found a problem.

When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database.

What's the solution for this kind of problem ?

Update: Well, I see some of the advice said disabling the submit button. This should prevent the form being submitted multiple times, but the problem is the form element in my page isn't refreshed, if I disable it the user won't be able to submit it anymore, disabling it for 15s may work, but is this the right way to solve this problem ?
