Javascript：使用jQuery提交Form表单

DEMO说明一切：

 // this is the id of the form
 $("#idForm").submit(function() {

    var url = "path/to/your/script.php"; // the script where you handle the form input.

     $.ajax({
            type: "POST",
            url: url,
            data: $("#idForm").serialize(), // serializes the form's elements.
            success: function(data)
            {
                alert(data); // show response from the php script.
            }
          });

     return false; // avoid to execute the actual submit of the form.
 });
