JavaScript如何创建和读取Cookie中的值?

如何在JavaScript中创建和读取Cookie中的值?

回答:

这是可用于创建和检索Cookie的功能。

function createCookie(name, value, days) {

var expires;

if (days) {

var date = new Date();

date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));

expires = "; expires=" + date.toGMTString();

}

else {

expires = "";

}

document.cookie = name + "=" + value + expires + "; path=/";

}

function getCookie(c_name) {

if (document.cookie.length > 0) {

c_start = document.cookie.indexOf(c_name + "=");

if (c_start != -1) {

c_start = c_start + c_name.length + 1;

c_end = document.cookie.indexOf(";", c_start);

if (c_end == -1) {

c_end = document.cookie.length;

}

return unescape(document.cookie.substring(c_start, c_end));

}

}

return "";

}
