我试图让 JavaScript 在显示隐藏的 div 之前验证表单中的所有数据。我一生都无法弄清楚我哪里出错了，一​​旦完成，我的第一个函数调用我的第二个函数。

所有 HTML、CSS 和 JavaScript 如下：

        <!DOCTYPE html>
    <html>
    <head>
    <title>Sign Up</title>
    <style text/css>

        position: relative
    }

只需添加show();到第一个函数的末尾即可。

或者更好的是，将这一行从show移到末尾validateForm：

function validateForm() {
    var fname = document.getElementById("fname");
    if (fname.value.length < 2) {
        alert("Please enter your First name!");
        return false;

你试过这个 

function validateForm() {
        var fname = document.getElementById("fname");
         if (fname.value.length < 2) {
          alert ("Please enter your First name!");
          return false;
    }
        var lname = document.getElementById ("lname");
          if (lname.value.length < 3) {
           alert ("Please enter your Surname!");
           return false;
    }
    var address = document.getElementById ("address");
          if (address.value.length < 1) {
           alert ("Please enter your House Number or Name!");
           return false;
    }
    var postcode = document.getElementById ("postcode");
          if (postcode.value.length < 6) {
           alert ("Please enter your Post Code!");

    }
    var x=document.forms["firstform"]["email"].value;
    var atpos=x.indexOf("@");
    var dotpos=x.lastIndexOf(".");
    if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length)
      {
      alert("Please enter a valid e-mail address");
      return false;
      }

     show();

    }

你只需要在最后调用这样的节目
