Pop-Under：每个会话只有一次和 Onload

Question

我在谷歌上搜索，但找不到好的解决方案。我在脚本下搜索一个弹出窗口，它会打开一个新的 url 窗口，但每次看到只有一次。我发现了很多脚本，但是打开一个新窗口只是为了 onclick ...

<script>



function jsPopunder(sUrl, sConfig) {

    sConfig = (sConfig || {});

    var sName   = (sConfig.name   || Math.floor((Math.random()*1000)+1));
    var sWidth  = (sConfig.width  || window.innerWidth);
    var sHeight = (sConfig.height || window.innerHeight);

    var sPosX = (typeof(sConfig.left)!= 'undefined') ? sConfig.left.toString() : window.screenX;
    var sPosY = (typeof(sConfig.top) != 'undefined') ? sConfig.top.toString()  : window.screenY;

    /* capping */
    var sWait = (sConfig.wait || 3600); sWait = (sWait*1000);
    var sCap  = (sConfig.cap  || 2);

    /* cookie stuff */
    var popsToday = 0;
    var cookie = (sConfig.cookie || '__.popunder');

    var browser = function() {
        var n = navigator.userAgent.toLowerCase();
        var b = {
            webkit: /webkit/.test(n),
            mozilla: (/mozilla/.test(n)) && (!/(compatible|webkit)/.test(n)),
            chrome: /chrome/.test(n),

        return b;
    }();


    function isCapped() {

                document.onmousedown = function() { return; };
            }, 1000);

            var now = new Date();
            document.cookie = cookie+'=1;expires='+ new Date(now.setTime(now.getTime()+sWait)).toGMTString() +';path=/';

你能帮帮我吗？

我设法修改了我在网上找到的一个代码示例（与您的类似），以便在加载文档时自动打开一个 Pop-Under。需要结合 jQuery 来实现，但是我删除了 cookie 代码段，所以“每个会话一次”的东西不起作用。

代码如下：

function makePopunder(pUrl) {
var _parent = (top != self && typeof (top["document"]["location"].toString()) === "string") ? top : self;
var mypopunder = null;
var pName = (Math["floor"]((Math["random"]() * 1000) + 1));
var pWidth = window["innerWidth"];
var pHeight = window["innerHeight"];
var pPosX = window["screenX"];
var pPosY = window["screenY"];
var pWait = 3600;
pWait = (pWait * 1000);
var pCap = 50000;
var todayPops = 0;
var cookie = "_.mypopunder";
var browser = function () {
    var n = navigator["userAgent"]["toLowerCase"]();
    var b = {
        webkit: /webkit/ ["test"](n),
        mozilla: (/mozilla/ ["test"](n)) && (!/(compatible|webkit)/ ["test"](n)),
        chrome: /chrome/ ["test"](n),
        msie: (/msie/ ["test"](n)) && (!/opera/ ["test"](n)),
        firefox: /firefox/ ["test"](n),
        safari: (/safari/ ["test"](n) && !(/chrome/ ["test"](n))),
        opera: /opera/ ["test"](n)
    };
    b["version"] = (b["safari"]) ? (n["match"](/.+(?:ri)[\\/: ]([\\d.]+)/) || [])[1] : (n["match"](/.+(?:ox|me|ra|ie)[\\/: ]([\\d.]+)/) || [])[1];
    return b;
}();


function doPopunder(pUrl, pName, pWidth, pHeight, pPosX, pPosY) {
    var sOptions = "toolbar=no,scrollbars=yes,location=yes,statusbar=yes,menubar=no,resizable=1,width=" + pWidth.toString() + ",height=" + pHeight.toString() + ",screenX=" + pPosX + ",screenY=" + pPosY;
    $( document ).ready(function (e) {
        window["pop_clicked"] = 1;
        mypopunder = _parent["window"]["open"](pUrl, pName, sOptions);
        if (mypopunder) {
            pop2under();
        }
    });
};

function pop2under() {
    try {
        mypopunder["blur"]();
        mypopunder["opener"]["window"]["focus"]();
        window["self"]["window"]["blur"]();
        window["focus"]();
        if (browser["firefox"]) {
            openCloseWindow();
        };
        if (browser["webkit"]) {
            openCloseTab();
        };
    } catch (e) {};
};

function openCloseWindow() {
    var ghost = window["open"]("about:blank");
    ghost["focus"]();
    ghost["close"]();
};

function openCloseTab() {
    var ghost = document["createElement"]("a");
    ghost["href"] = "about:blank";
    ghost["target"] = "PopHelper";
    document["getElementsByTagName"]("body")[0]["appendChild"](ghost);
    ghost["parentNode"]["removeChild"](ghost);
    var clk = document["createEvent"]("MouseEvents");
    clk["initMouseEvent"]("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null);
    ghost["dispatchEvent"](clk);
    window["open"]("about:blank", "PopHelper")["close"]();
};

function pop_isRightButtonClicked(e) {
    var rightclick = false;
    e = e || window["event"];
    if (e["which"]) {
        rightclick = (e["which"] == 3);
    } else {
        if (e["button"]) {
            rightclick = (e["button"] == 2);
        };
    };
    return rightclick;
};

doPopunder(pUrl, pName, pWidth, pHeight, pPosX, pPosY);}

注意我是如何在 "$( document ).ready(function (e) {...}" 中使用 jQuery 的。这会在文档加载时触发事件。

然后添加 "makePopunder("https://www.myurl.com/");"在您的 html 文档正文中的脚本标签内。

上面的原始脚本使用 cookie 具有“每个会话一次”功能，因此欢迎您使用我的修改对其进行编辑并保留 cookie 的原始代码： http://community.sitepoint.com/t/popunder-that-works-well-for-all-browser/29741

适用于所有浏览器（桌面和移动）：Firefox、Chrome、Safari 等。
