javaScript正则之form验证

对form表单进行简单的验证，错误之处，原来者指正，谢谢！

function check(Form) { var nameExpression = /[^\u4E00-\u9FA5]/; var PnumExpression = /^\d{17}[\d|X]|^\d{15}$/; var EmailExpression = /\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w)*/; var TelephoneExpression = /^1[2-9]{1}\d{9}$/; var userNameExpression = /^(\w){3,10}$/;//3-10位的字母、数字、下划线组成的 var passwordExpression = /^[A-Za-z]{1}([A-Za-z0-9]|[._]){5,19}$/;//6-20位的字母、数字、下划线和点组成的 var NameEx = new RegExp(nameExpression); var PnumEx = new RegExp(PnumExpression); var EmailEx = new RegExp(EmailExpression); var TelephoneEx = new RegExp(TelephoneExpression); var userNameEx = new RegExp(userNameExpression); var passwordEx = new RegExp(passwordExpression); for(var i = 0; i < Form.length; i++){ if(Form.elements[i].value == ""){ alert(Form.elements[i].id + "不能为空"); Form.focus(); return false; } } var strName = Form.name.value; if(NameEx.test(strName)){ alert("输入的真是姓名不正确"); return false; }z var pNum = Form.Pnum.value; if(!PnumEx.test(pNum)){ alert("输入的身份证号码不正确"); return false; } var strEmail = Form.email.value; if(!EmailEx.test(strEmail)){ alert("Email格式不对"); return false; } var strTelephone = Form.telephone.value; if(!TelephoneEx.test(strTelephone)){ alert("请输入正确的手机号码"); return false; } var strUserName = Form.userName.value; if(!userNameEx.test(strUserName)){ alert("请输入3-10位的字母、数字、下划线组成的用户名"); return false; } var strpPassword = Form.password.value; if(!passwordEx.test(strpPassword)){ alert("请输入6-20位的字母、数字、下划线和点组成的密码"); return false; } return true; }
