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
}
};
