php+js+mysql设计的仿webQQ-其他验证

来看看其他验证是不是很简单啦!

<2>昵称验证

Js代码

function checkNickname(Nickname)
{       
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    { 
document.getElementById("error2").innerHTML="<font color=red size=2px>*</font>";   //复位
           if(Nickname.length==0)
              {
                        document.getElementById("error2").innerHTML="<font color=red size=2px>*昵称不能为空！</font>";
                  }
           else
              {
                        if(Nickname.length>16)
                           {
                                  document.getElementById("error2").innerHTML="<font color=red size=2px>*昵称不要超过16个字符！</font>";
                           }
                         else
                           {
                              document.getElementById("error2").innerHTML="<font color=green size=2px>*昵称可用！</font>";
                           }
                  }
    }
  } 
xmlhttp.open("GET","index.php",true);
xmlhttp.send();         //注意这里与邮箱验证的不同
}

<3>密码验证

Js代码

function checkPwd1(password1)
{       
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {  document.getElementById("error3").innerHTML="<font color=red size=2px>*</font>";
       document.getElementById("password2").value="";
       document.getElementById("error4").innerHTML="<font color=red size=2px>*</font>";
           if(password1.length==0)
              {
                        document.getElementById("error3").innerHTML="<font color=red size=2px>*密码不能为空！</font>";
                        
                  }
           else
              {
                        if(password1.length<6||password1.length>16)
                           {
                                  document.getElementById("error3").innerHTML="<font color=red size=2px>*密码为6-16个字符！</font>";
                                  
                           }
                         else
                           {  
                               var reg=/[a-zA-Z0-9]/;     //在js中使用正则表达式
                                   if(reg.test(password1))
                                  {
                                             document.getElementById("error3").innerHTML="<font color=green size=2px>*密码可用！</font>";
                                           }
                                   else
                                      {
                                                 document.getElementById("error3").innerHTML="<font color=red size=2px>*密码不可用！</font>";
                                                 
                                          }        
                           }
                  }
    }
  } 
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}

<4>重复密码验证

Js代码

function checkPwd2(password2)
{       
var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {  document.getElementById("error4").innerHTML="<font color=red size=2px>*</font>";
           if(password2.length==0)
              {
                        document.getElementById("error4").innerHTML="<font color=red size=2px>*请确认密码！</font>";
                        
                  }
           else
              {
                        if(password2!=document.getElementById("password1").value)
                           {
                                  document.getElementById("error4").innerHTML="<font color=red size=2px>*两次密码输入不一致！</font>";
                                  
                           }
                        else 
                           {
                                  document.getElementById("error4").innerHTML="<font color=green size=2px>*密码输入一致！</font>";
                           }
                        
                  }
    }
  } 
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}

怎么样，挺简单的吧！（未完待续）
