代码如下<script>
window.onload =function(){
varoForm = document.getElementById('loginForm');
varoUser = document.getElementById('user');
varoPswd = document.getElementById('pswd');
varoRemember = document.getElementById('remember');
//页面初始化时，如果帐号密码cookie存在则填充
if(getCookie('user') && getCookie('pswd')){
oUser.value = getCookie('user');
oPswd.value = getCookie('pswd');
oRemember.checked =true;
}
//复选框勾选状态发生改变时，如果未勾选则清除cookie
oRemember.onchange =function(){
if(!this.checked){
delCookie('user');
delCookie('pswd');
}
};
//表单提交事件触发时，如果复选框是勾选状态则保存cookie
oForm.onsubmit =function(){
if(remember.checked){
setCookie('user',oUser.value,7);//保存帐号到cookie，有效期7天
setCookie('pswd',oPswd.value,7);//保存密码到cookie，有效期7天
}
};
};
//设置cookie
functionsetCookie(name,value,day){
vardate =newDate();
date.setDate(date.getDate() + day);
document.cookie = name +'='+ value +';expires='+ date;
};
//获取cookie
functiongetCookie(name){
varreg = RegExp(name+'=([^;]+)');
vararr = document.cookie.match(reg);
if(arr){
returnarr[1];
}else{
return'';
}
};
//删除cookie
functiondelCookie(name){
setCookie(name,null,-1);
};
</script>
