Modalpreview 介绍
Modalpreview is a lightweight jQuery script that makes it possible to preview
the textarea content in a modal window before submitting the form.
Modalpreview automatically adds a preview button next to the submit button
that brings up a modal window containing the textarea content, without
reloading the entire page. It converts line breaks to
and removes the tag to prevent hacking. Modalpreview can also strip HTML
before rendering the preview.
Tested in Safari 3, Firefox 2, MSIE 6, MSIE 7, Opera 9
