<form name="reg" method="post" onSubmit="return checkForm1();" action="yp.asp?action=add">  

为什么表单提交的时候不检查文本框的内容呢。只能检测到名字是否为空其他的都检查不出来就成功提交到数据库了。

<SCRIPT language=JavaScript>

function checkForm()


{
  
  if (document.reg.name.value.length ==""){
        alert ("提示：\n\n请输入您的真实姓名！");
        document.reg.name.focus();
        return false;
    }
 if (document.reg.name.value.length < 2 || document.reg.name.value.length > 8){
        alert ("提示：\n\n姓名必须在2-8字之间！");
        document.reg.name.focus();
        return false;
    }
  

 if (document.reg.h_province.value=='请选择')
  {
                alert ("提示：\n\n请选择您目前所在地！")
                document.reg.x_city.focus();
        return false;
  }

      
      
   if (document.reg.Mobile.value=='')
   {
    alert ("提示：\n\n请输入您的手机号码!")
     document.reg.Mobile.focus();
          return false;
   }

   
  return true;
}

</SCRIPT>

onSubmit="return checkForm1();" 这里是checkForm1 而函数是checkForm()

return checkForm()是刚发表的时候写错了。这个一般是哪里出问题不能检查呢。名字文本框的值可以检查，后面的都不行，只要姓名文本框值满足就提交了

if (document.reg.name.value.length ==""){
        alert ("提示：\n\n请输入您的真实姓名！");
        document.reg.name.focus();
        return false;
    }
if (document.reg.name.value.length < 2 || document.reg.name.value.length > 8){
        alert ("提示：\n\n姓名必须在2-8字之间！");
        document.reg.name.focus();
        return false;
    }

把表单的HTML代码一起发上来，我来试试

function checkForm()


{
  
  if (document.reg0.name.value ==""){
        alert ("提示：\n\n请输入您的真实姓名！");
        document.reg0.name.focus();
        return false;
    }
 if (document.reg0.name.value.length < 2 || document.reg0.name.value.length > 8){
        alert ("提示：\n\n姓名必须在2-8字之间！");
        document.reg0.name.focus();
        return false;
    }
  


 if (document.reg0.h_province.value=="请选择")
  {
                alert ("提示：\n\n请选择您目前所在地！")
                document.reg0.h_province.focus();
        return false;
  }

  if (document.reg0.h_city.value0=="城市")
  {
                alert ("提示：\n\n请选择您的户口所在地！")
                document.reg0.h_city.focus();
        return false;
  }

 if (document.reg0.x_province.value=="请选择")
  {
                alert ("提示：\n\n请选择您目前所在地！")
                document.reg0.x_city.focus();
        return false;
  }

  if (document.reg0.x_city.value=="城市")

你给的代码也太多了。


下拉列表框的“请选择”项目的对应Value是""
<option value="">请选择</option>
所以js代码中if (document.reg0.h_province.value=="请选择") 就不对了，应该是if (document.reg0.h_province.value=="")   
所有下拉列表框都油这个问题

代码太多了，不知道还有没有其他问题

js代码是严格限制大小写的，你要确认你的表单名称和JS代码大小写一致
