本文主要和大家分享js实现获取网站搜索来源代码，把以下代码引入所有页面，即可实现收集系统来源的功能，在任意页面中都可以使用全局的统一的来源信息，希望能帮助到大家。var args = {

mySite:"localhost",

subSite:"子网站，比如移动端: m.xxx.com"

}

var index = (function(a) {

var c = "";

var d = args.mySite;

a(function() {

var g = function() {

return function(k, l, j) {

var h = j * 24 * 60 * 60 * 1000;

var i = new Date();

i.setTime(i.getTime() + h);

var e = "; expires=" + i.toGMTString();

document.cookie = k + "=" + escape(l) + e + "; path=/"

}

};

try {

if (document.referrer.indexOf(d) <= 0 || document.referrer.indexOf(d) > 10) {

g().call(window, "regCompanyName", document.referrer.substring(0, 40) + "||" + window.location.href, 30)

}

} catch (f) {

}

});

var b = function() {

try {

if (getCookie) {

return getCookie

}

} catch (f) {}

return function(e) {

if (document.cookie.length > 0) {

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

if (c_start != -1) {

c_start = c_start + e.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 null

}

};
