varcheckAgree=document.getElementById('checkAgree');
varform=document.getElementById('form');
varemailReg=/^w+((-w+)|(.w+))*@[A-Za-z0-9]+((.|-)[A-Za-z0-9]+)*.[A-Za-z0-9]+$/;
if(username==''){
alert('用户名不能为空');
document.getElementById('username').focus();
returnfalse;
}
if(pwd==\"\"){
//不能为空
}
if(pwd.lentht
//长度不能小于6位
}
if(pwd!=rePwd){
//密码确认密码不一致
}
//日期的话建议用日历控件可以参考网上自己弄一弄
if(!emailReg.test(email)){
//邮箱格式不对
}
if(!checkAgree.checked){
//尚未统一协议
}
//所有验证通过之后提交表单
//form.submit();
}
写了基本的东西出来还是希望你能自己研究研究自己动手搞定
