访问a BBC episodes page时，我希望从Greasemonkey脚本中调用“ SHOW MORE”。
我尝试了六种方法，但均无效果。我想我缺少一些基本知识。

谢谢

最佳答案

这是一个非常普遍的问题。有关如何解决此类问题的更多详细信息，请参见"Choosing and activating the right controls on an AJAX-driven site"。

给定该配方，唯一的技巧/技能/难点在于选择正确的jQuery选择器。在这种情况下，可以通过以下方式可靠地使用“显示更多”链接：

#synopsis div.copy a.show-more-truncate

因此，完整的工作脚本将是：

// ==UserScript==
// @name     _BBC episode, click "Show More" link
// @include  http://www.bbc.co.uk/programmes/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/

waitForKeyElements (
    "#synopsis div.copy a.show-more-truncate", clickShowMoreLink, true
);

function clickShowMoreLink (jNode) {
    var clickEvent = document.createEvent('MouseEvents');
    clickEvent.initEvent ("click", true, true);
    jNode[0].dispatchEvent (clickEvent);
}
