我正在使用下面的脚本来验证我的联系人表单。

//submission scripts
  $('.contactForm').submit( function(){
        //statements to validate the form   
        var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
        var email = document.getElementById('e-mail');
        if (!filter.test(email.value)) {
            $('.email-missing').show();
        } else {$('.email-missing').hide();}
        if (document.cform.name.value == "") {
            $('.name-missing').show();
        } else {$('.name-missing').hide();} 

        if (document.cform.phone.value == "") {
            $('.phone-missing').show();
        } 
        else if(isNaN(document.cform.phone.value)){
        $('.phone-missing').show();
        }
        else {$('.phone-missing').hide();}  

        if (document.cform.message.value == "") {
            $('.message-missing').show();
        } else {$('.message-missing').hide();}  

        if ((document.cform.name.value == "") || (!filter.test(email.value)) || (document.cform.message.value == "") || isNaN(document.cform.phone.value)){
            return false;
        } 

        if ((document.cform.name.value != "") && (filter.test(email.value)) && (document.cform.message.value != "")) {
            //hide the form
            //$('.contactForm').hide();

            //show the loading bar
            $('.loader').append($('.bar'));
            $('.bar').css({display:'block'});

        /*document.cform.name.value = '';
        document.cform.e-mail.value = '';
        document.cform.phone.value = '';
        document.cform.message.value = '';*/

            //send the ajax request
            $.post('mail.php',{name:$('#name').val(),
                              email:$('#e-mail').val(),
                              phone:$('#phone').val(),
                              message:$('#message').val()},

            //return the data
            function(data){

              //hide the graphic
              $('.bar').css({display:'none'});
              $('.loader').append(data);

            });

            //waits 2000, then closes the form and fades out
            //setTimeout('$("#backgroundPopup").fadeOut("slow"); $("#contactForm").slideUp("slow")', 2000);

            //stay on the page
            return false;


        } 
  });

这是我的表格

<form action="mail.php" class="contactForm" id="cform" name="cform" method="post">
  <input id="name" type="text" value="" name="name" />
  <br />
  <span class="name-missing">Please enter your name</span>
  <input id="e-mail" type="text" value="" name="email" />
  <br />
  <span class="email-missing">Please enter a valid e-mail</span>
  <input id="phone" type="text" value="" name="phone" />
  <br />
  <span class="phone-missing">Please enter a valid phone number</span>
  <textarea id="message" rows="" cols="" name="message"></textarea>
  <br />
  <span class="message-missing">Please enter message</span>
  <input class="submit" type="submit" name="submit" value="Submit Form" />
</form>

提交成功后,我需要清除表单字段值。我该怎么做?

用户回答回答于
$("#cform")[0].reset();

或者用普通的javascript:

document.getElementById("cform").reset();

可以在$.post调用成功回调中这样做

$.post('mail.php',{name:$('#name').val(),
                              email:$('#e-mail').val(),
                              phone:$('#phone').val(),
                              message:$('#message').val()},

            //return the data
            function(data){

              //hide the graphic
              $('.bar').css({display:'none'});
              $('.loader').append(data);

              //clear fields
              $('input[type="text"],textarea').val('');

            });
