Ajax jQuery同步回调成功

Ajax jQuery同步回调成功

您需要为以下同步请求设置async：false：

function doop(){        var that = this;        var theold = $(this).siblings('.theold').html();        var thenew = $(this).siblings('.thenew').val();        $.ajax({     async: false,     url: 'doop.php',     type: 'POST',     data: 'before=' + theold + '&after=' + thenew,     success: function(resp) {  if(resp == 1) {          $(that).siblings('.theold').html(thenew);  }     }        });        // some other pre        return false;}
