js implementation to obtain website search source code

This article mainly shares with you the js implementation of obtaining website search source code. Introducing the following code into all pages can realize the function of collecting system sources. Global unified source information can be used in any page. I hope it can help. Everyone.

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
        }
    };
})(jQuery);
