javascript js 操作cookie

function SetCookie(sName, sValue) {

	var date = new Date();
	date.setMonth(date.getMonth() + 1);

	var value = sName + "=" + sValue; //escape(sValue);
	document.cookie = value+ "; expires=" + date.toUTCString();
}
function GetCookie(name) {
	var cookies = document.cookie;
	var list = cookies.split("; ");     // 解析出名/值对列表

	for (var i = 0; i < list.length; i++) {
		var arr = list[i].split("=");   // 解析出名和值
		if (arr[0] == name)
			return decodeURIComponent(arr[1]);   // 对cookie值解码
	}
	return "";
}
