这篇文章主要介绍了实现类似facebook无刷新ajax更新,需要的朋友可以参考下
代码如下:<script type="text/javascript">$(document).ready(function(){$('.edit_link').click(function(){$('.text_wrapper').hide();var data=$('.text_wrapper').html();$('.edit').show();$('.editbox').html(data);$('.editbox').focus();});$(".editbox").mouseup(function(){return false});$(".editbox").change(function(){$('.edit').hide();var boxval = $(".editbox").val();var dataString = 'data='+ boxval;$.ajax({type: "POST",url: "update_profile_ajax.php",data: dataString,cache: false,success: function(html){$('.text_wrapper').html(boxval);$('.text_wrapper').show();}});});$(document).mouseup(function(){$('.edit').hide();$('.text_wrapper').show();});});</script><style type="text/css">body{font-family:Arial, Helvetica, sans-serif;font-size:12px;}.mainbox{width:250px;margin:50px;}.text_wrapper{border:solid 1px #0099CC;padding:5px;width:187px;}.edit_link{float:right}.editbox{overflow: hidden; height: 61px;border:solid 1px #0099CC; width:190px; font-size:12px;font-family:Arial, Helvetica, sans-serif; padding:5px}</style><div class="mainbox"><a href="#" class="edit_link" title="Edit">Edit</a><?phpinclude("db.php");$sql=mysql_query("select email from users where user_id='1'");$row=mysql_fetch_array($sql);$profile=$row['email'];?><div class="text_wrapper" style=""><?php echo $profile; ?></div><div class="edit" style="display:none"><textarea class="editbox" cols="23" rows="3" name="profile_box"></textarea></div></div>update_profile_ajax.php代码如下:<?phpif($_POST['data']){$data=$_POST['data'];$data = mysql_escape_String($data);$sql = "update users set email='$data' where user_id='1'";mysql_query( $sql);}?>
