如何在CasperJS中自动滚动到任何站点的底部？

如何解决如何在CasperJS中自动滚动到任何站点的底部？

我的代码是 this script 的变体。我基本上是尝试在页面底部滚动并获取所有 HTML 代码。我在 2 个网站上对此进行了测试，它在 http://quotes.toscrape.com/scroll 上运行良好，但在另一个网站 (https://scrapingclub.com/exercise/list_infinite_scroll/) 上它滚动到一个点然后停止。

phantom.casperPath = "../../casperjs/";

phantom.injectJs(phantom.casperPath + "/bin/bootstrap.js");

var casper = require('casper').create({
    viewportSize: { width: 1680,height: 1050 }
});

casper.userAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML,like Gecko) Version/14.0 Safari/605.1.15");

casper.start('https://scrapingclub.com/exercise/list_infinite_scroll/'); // not working
//casper.start('http://quotes.toscrape.com/scroll'); // works

var scrolled = 0; // keep track of how much we have scrolled
var scrollDelta = 0; // Keep track of how much our new scroll position differs from our last

var getContent = function() {
    casper.wait(10000,function(){
        casper.scrollToBottom();
        var newScrolled = casper.evaluate(function() {
            //return __utils__.getDocumentHeight(); 
            return window.scrollY; // grab how far the window is scrolled
        });
        scrollDelta = newScrolled - scrolled;
        scrolled = newScrolled;
        // console.log("Now scrolled",scrolled);
        // console.log("Scroll Delta",scrollDelta);
    });
    casper.then(function() { // After we scroll to the bottom
        if (scrollDelta != 0) {
            getContent(); // If scrollDelta _has_ changed,recursively call getContent
        } else {
            casper.then(function() {
                var html = String(casper.getHTML());
                this.echo(html);
            });
        }
    });
};

getContent();

casper.run();

我尝试将 casper.scrollToBottom() 函数更改为此

this.page.scrollPosition = { 
            top: this.page.scrollPosition["top"] + document.body.scrollHeight,left: 0 
        };

但我得到了相同的结果。
