I am looking for a way to use jQuery to allow a user to look at a modal window "preview" of a form before they submit the form to be saved.

I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window.

I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this?

This is what I am currently using:

<script language="JavaScript">
function preview(form) {
  form.target='_blank';
  form.action='http://example.com/preview.php';
  form.submit();
}
</script> 
<input type="button" value="preview" onclick='preview(this.form)'>
