本文实例讲述了jquery实现用户信息修改验证输入方法。分享给大家供大家参考。具体如下：

var realnameFlag = 0; var addressFlag = 0; var zipFlag=0; var cellphoneFlag=0; var homephoneFlag=0; var oldpasswordFlag=1; var newpasswordFlag=1; //判断email function check_email() { $("#showSpan").hide(); var email = $.trim($("#email").val()); if (email == null || email == "") { emailFlag = 1; $("#emailMsg").html("<span>请输入邮箱信息</span>"); return; } // 判断输入框内是否为邮箱格式 if (email.replace(/[^x00-xff]/g, "**").length <= 4 || email.replace(/[^x00-xff]/g, "**").length >= 50) { $("#emailMsg").html("<span>邮箱长度不正确</span>"); emailFlag = 1; return ; } var reg = /^[w-]+(.[w-]+)*@[w-]+(.[w-]+)+$/; if (reg.test(email)) { $("#emailMsg").html(""); emailFlag = 0; return ; } else { $("#emailMsg").html("<span>邮箱格式不正确</span>"); emailFlag = 1; return ; } } function check_realname() { $("#showSpan").hide(); var realname = $.trim($("#realname").val()); // 判断是否为空 if (realname == null || realname == "") { $("#realnameMsg").html("<span>请输入真实姓名，20个英文或10个汉字</span>");
