Hi, Base on my previous test, I add one simple ajax function. Now, the submit function does not work correctly under Safari and Opera, but still works fine under IE/FF. I will try write AJAX call in javascript(without jquery), because I am not sure it's compatibility problem of Jquery or javascript. Thanks.
