关于cookies的设置与获取

在项目中遇上需要把查询的时间实现到每一个页面中，自然就想到了cookies，

 

//获取cookie a为设置cookie的名字

function getcookie(a) {

var cookie = document.cookie;

var ydx = "";

var start1 = cookie.indexOf(a + "=");

if (start1 == -1) {

ydx = "";

} else {

start = cookie.indexOf("=", start1) + 1;

var end = cookie.indexOf(";", start);

if (end == -1) {

end = cookie.length;

}

var value = unescape(cookie.substring(start, end));

if (value == null) {

ydx = "";

} else {

ydx = value;

}

}

return ydx;

}

// 保存cookie b后面加;path/是让cookie在根目录下保存

function SetCookie(a, b, c) {

if (c == 1) {

document.cookie =

a +

"=" +

b +

";expires=" +

new Date(new Date().getTime() + 365 * 24 * 60 * 60 * 1000).toGMTString() +

";path=/";

} else {

document.cookie = a + "=" + b + ";path=/";

}

}
