r - 如何检查页面是否在 RSelenium 中完成加载

Question

想象一下，您使用 RSelenium 单击一个元素。在页面上，并希望从结果页面中检索结果。如何检查以确保结果页面已加载？我可以插入 Sys.sleep()在处理页面和单击元素之间，但这似乎是一种非常丑陋且缓慢的做事方式。

Answer 1

套装ImplicitWaitTimeout然后在页面上搜索一个元素。来自 ?remoteDriver

setImplicitWaitTimeout(milliseconds = 10000)

Set the amount of timethe driver should wait when searching for elements. When searching fora single element, the driver will poll the page until an element isfound or the timeout expires, whichever occurs first. When searchingfor multiple elements, the driver should poll the page until at leastone element is found or the timeout expires, at which point it willreturn an empty list. If this method is never called, the driver willdefault to an implicit wait of 0ms.
