现在我们把check.js文件代码来看看吧.

function c(){
  var uid =document.getElementById('uid').value;
  var pwd =document.getElementById('password').value;
  var pwd2=document.getElementById('password2').value;
  var mo =document.getElementById('mo').value;
  var name=document.getElementById('name').value;  
  
  if( uid=='' || uid.length>12 || uid.length<3 ){
    document.getElementById('u_info').innerHTML='<div id=error>昵称长度为3-12字符!</div>'; 
    return false;
  }else{
    document.getElementById('u_info').innerHTML='<div class="defult">用户名长度3-12位</div>';
  }
  
  
  if(pwd =='' || pwd!=pwd2 || pwd.length<6 || pwd.length>12){
    document.getElementById('p_info').innerHTML='<div id=error>密码不能为空或二次输入的密码不一致!</span>';
    return false;
  }else{
    document.getElementById('p_info').innerHTML='<div id=success></div>';
    document.getElementById('p_info1').innerHTML='<div id=success></div>';
  }
  
  if( mo.match(/^[0-9]{3,4}-[0-9]{7,8}$/) || mo.match(/^(((d{3}))|(d{3}-))?13d{9}$/) ){
    document.getElementById('m_info').innerHTML='<div id=success></div>';
  }else{

    return false;

  if( name=='' || name.length>12 || name.length<2 ){

ajax验证文章我以前写过很多哦,下面我再来写一个ajax检查用户名的教程吧,全部贴上来.

这里是界面效果图片,我们主要有三个文章一个reg.php里面几乎是html 代码,一个是register.php注册文件,一个是否chech.js文件,还有最后一个ajax_check.php文件,要完成这次ajax 用户检测就要用到上面四个文章下面我们就先来看看界面代码吧.

css 与js代码.导入
