Question

我希望每隔30分钟搜索一次随机谷歌查询（例如https://www.google.com/?q=OjRfujaM）。我需要在不打开新选项卡的情况下搜索它。

请解释我如何做到这一点。

感谢。

这里是一段代码，它将从一组搜索短语中随机选择，打开一个新窗口，然后在该窗口中对该短语进行谷歌搜索，然后按一定时间间隔将该窗口更改为一个新的谷歌搜索。您没有说出如何选择随机搜索短语，所以我想办法做到这一点，但您显然可以插入自己的方法。这是代码working demo：

var searchWindow, interval;
var searchPhrases = [
    "california earthquake", "desean jackson", "noah", 
    "louisville basketball", "ultra music festival", "january jones",
    "stephen colbert", "taco bell breakfast", "college board",
    "zac efron", "johnny manziel", "miguel cabrera", "psych"
];
function getRandomSearchPhrase() {
    var rand = Math.floor(Math.random() * searchPhrases.length);
    return searchPhrases[rand];
}

function makeRandomGoogleSearchURL() {
    var search = encodeURI(getRandomSearchPhrase().replace(/\s/g, "+"));
    var url = "https://www.google.com?q=" + search + "#q=" + search;
    return url;
}

// create the interval portion to refresh the Google search
// use short time here for purposes of the demo
function startInterval() {
    if (interval) {
        window.clearInterval(interval);
    }
    interval = window.setInterval(function() {
        if (searchWindow && searchWindow.location) {
            // stop the interval if the window has been closed
            searchWindow.location = makeRandomGoogleSearchURL();
        } else {
            window.clearInterval(interval);
            searchWindow = null;
        }
    }, 5000);
}

// hook up the button to start it all
document.getElementById("start").addEventListener("click", function() {
    if (!searchWindow || !searchWindow.location) {
        searchWindow = window.open(makeRandomGoogleSearchURL(), "myGoogleSearch");
        startInterval();
    }
})
