javascript - 提交时显示成功消息的 Jquery 表单

Question

我有一个使用 Jquery 显示消息的表单

*字段必填错误消息

如果表单已提交，我试图让它显示成功消息。

只要填写了 req 字段，表单就会提交。

如果填写了所有“req”字段，有谁知道我如何修改此代码以显示“成功”div？

谢谢

    $(function() {
       function validateform() {
          var valid = true;
          $(".req").css("border","1px solid #ccc");
          $(".req").each(function() {
             if ( $(this).val() == "" || $(this).val().replace(/\s/g, '').length == 0 ) {
                $(this).css("border","1px solided");$(".required").css("display","block");
                valid = false;
             }
          });
          return valid;
       }    
       $("#submit").click( function() {
          $('#myform').submit( validateform );
          $('$name').submit();
       });  
   });

           submitHandler: function(form){
                  $(form).ajaxSubmit({
    target: '#preview', 
    success: function() {  
    $('#form id').slideDown('slow'),
<!-- RESET THE FORM FIELDS AFTER SUBMIT STARTS HERE-->
    $("#form")[0].reset();
<!--RESET THE FORM FIELDS AFTER SUBMIT  ENDS HERE--->
    } 

}); 

                }

There are two simple ways that will allow you to render a success message. You can either use ajax with the callback success function, or if you want a full post, you you can check at the top of your file if a certain POST was set, and if so, render a success message.

Here is an example of checking POST:

if(isset($_POST['name attribute posting'])) {
    $util->showSuccessMessage();
    //OR echo "<div class='popup'></div>"
}

And here is an example of using Ajax's success callback function:

function submitForm() {
    $.ajax({
        url : 'this_file.php',
        type: 'POST',
        success : showSuccessMessage   //function call
    })
}
