我在搜索完成后试图抓取google play商店页面,即这一个: https://play.google.com/store/search?q=stackoverflow&c=apps
正如您所看到的,当您滚动到页面末尾时会加载新的应用,有时会出现“显示更多”的内容。按钮也。我正在制作一个需要完成所有这些滚动的书签,但我无法使其正常工作。这是我目前的代码:
var appContainerDiv = document.getElementsByClassName("card-list two-cards")[0];
var numberOfApps = appContainerDiv.childNodes.length;
var numberOfApps2 = numberOfApps;
do {
numberOfApps = numberOfApps2;
window.scrollTo(0, document.body.scrollHeight);
if (document.getElementById('show-more-button') !== null) {
document.getElementById('show-more-button').click();
}
numberOfApps2 = document.getElementsByClassName("card-list two-cards")[0].childNodes.length;
}
while (numberOfApps2 > numberOfApps);
appContainerDiv是div,其中所有应用都是嵌套的。

var delay = 2000;
var height = document.body.scrollHeight;
window.scrollTo(0, document.body.scrollHeight);
var interval = setInterval(function() {
window.scrollTo(0, document.body.scrollHeight);
if (document.getElementById('show-more-button') !== null) {
document.getElementById('show-more-button').click();
}
if (height == document.body.scrollHeight) {
clearInterval(interval);
}
} else {
height = document.body.scrollHeight;
}
}, delay);
