Jquery .load（）包含来自表单的数据

I am trying to load a page into a modal window "checkout.php" after submitting a form, but I need it to load with the results of the form. Normally, one would just set the action of the form to the url and the data gets passed, but in this case, the page needs to be loaded into a modal with that data which requires the use of more jQuery than I know.I am trying to load a page into a modal window
