localStorage的设置与获取：

/**
 * 设置 localStorage 存储信息
 * @param k
 * @param v
 * @returns
 */
function setlocalStorage(k,v){
//	localStorage.k = escape(JSON.stringify(v));	
    localStorage.setItem(k, escape(JSON.stringify(v)));
}

/**
 * 获取 localStorage 中存储的信息
 * @param k
 */
function getlocalStorage(k){
//	var myUser = localStorage.k;
//    if(myUser)myUser = unescape(myUser);
//    return JSON.parse(myUser || "{}");
    
    return JSON.parse(unescape(localStorage.getItem(k)));
}

cookie的设置、获取与删除：

/**
 * 设置 cookie 值
 * @param k
 * @param v
 * @returns
 */
function setCookie(k,v){
	
	/*var Days = 1; //此 cookie 将被保存 1 天
	var exp = new Date(); //new Date("December 31, 9998");
	exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);
	document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();*/
	
	if(k!=null&&k!=''){
		document.cookie=k+"="+escape(v);
	}
}

/**
 * 获取 cookie 值
 * @param cname
 * @returns
 */
function getCookie(cname){
	
	/*var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));
	if(arr != null){
		return unescape(arr[2]);
	}
	return null;*/
	
	var name = cname + "=";
	var ca = document.cookie.split(';');
	for(var i=0; i<ca.length; i++){
		var c = ca[i].trim();
		if (c.indexOf(name)==0){
	    	var val = c.substring(name.length,c.length);
	    	return unescape(val);
	    }
	}
	return "";
}

/**
 * 删除 cookie 值
 * @param cname
 */
function delCookie(cname){
	var exp = new Date();
	exp.setTime(exp.getTime() - 1);
	var cval=getCookie(cname);
	if(cval!=null){
		document.cookie = cname + "=" + cval + ";expires=" + exp.toGMTString();
	}
