当我单击提交按钮时，它会显示正确的验证，但是在该警报消息之后页面正在刷新并且我丢失了字段中的所有其他数据：S，我怎样才能使它仍然保持其他字段的填充状态。

我尝试在调用提交事件后删除 window.location.reload() 但仍然无法正常工作：S。任何人有什么建议吗？

这是代码：

function formValidation() {
  var uid = document.registration.userid;
  var passid = document.registration.passid;
  var uname = document.registration.username;
  var uadd = document.registration.address;
  var ucountry = document.registration.country;
  var uzip = document.registration.zip;
  var uemail = document.registration.email;
  var umsex = document.registration.msex;
  var ufsex = document.registration.fsex;
  if (userid_validation(uid, 5, 12)) {
    if (passid_validation(passid, 7, 12)) {
      if (allLetter(uname)) {
        if (alphanumeric(uadd)) {
          if (countryselect(ucountry)) {
            if (allnumeric(uzip)) {
              if (ValidateEmail(uemail)) {
                if (validsex(umsex, ufsex)) {}
              }
            }
          }
        }
      }
    }
  }
  return false;

}
function userid_validation(uid, mx, my) {
  var uid_len = uid.value.length;
  if (uid_len == 0 || uid_len >= my || uid_len < mx) {
    alert("User Id should not be empty / length be between " + mx + " to " + my);
    uid.focus();
    return false;
  }
  return true;
}

function passid_validation(passid, mx, my) {
  var passid_len = passid.value.length;
  if (passid_len == 0 || passid_len >= my || passid_len < mx) {
    alert("Password should not be empty / length be between " + mx + " to " + my);
    passid.focus();
    return false;
  }
  return true;
}

function allLetter(uname) {
  var letters = /^[A-Za-z]+$/;
  if (uname.value.match(letters)) {
    return true;
  } else {
    alert('Username must have alphabet characters only');
    uname.focus();
    return false;
  }
}

function alphanumeric(uadd) {
  var letters = /^[0-9a-zA-Z]+$/;
  if (uadd.value.match(letters)) {
    return true;
  } else {
    alert('User address must have alphanumeric characters only');
    uadd.focus();
    return false;
  }
}

function countryselect(ucountry) {
  if (ucountry.value == "Default") {
    alert('Select your country from the list');
    ucountry.focus();
    return false;
  } else {
    return true;
  }
}

function allnumeric(uzip) {
  var numbers = /^[0-9]+$/;
  if (uzip.value.match(numbers)) {
    return true;
  } else {
    alert('ZIP code must have numeric characters only');
    uzip.focus();
    return false;
  }
}

function ValidateEmail(uemail) {
  var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
  if (uemail.value.match(mailformat)) {
    return true;
  } else {
    alert("You have entered an invalid email address!");
    uemail.focus();
    return false;
  }
}
function validsex(umsex, ufsex) {
  x = 0;

  if (umsex.checked) {
    x++;
  }
  if (ufsex.checked) {
    x++;
  }
  if (x == 0) {
    alert('Select Male/Female');
    umsex.focus();
    return false;
  } else {
    alert('Form Succesfully Submitted');
    window.location.reload()
    return true;
  }
}

两个问题...

  1. 缺少退货

    onSubmit="return formValidation();"

  2. 缺少返回真；

    if (validsex(umsex, ufsex)) { 返回真；}
