问题 I'm building an app (ES6) and I'm curious what is the 'correct' way to catch scroll up / down events? I tried (npm) installing react-scroll-listener but I couldn't get it to work with my ES6 class.

问题 I have a fixed image that overlays a page when the user is in the act of scrolling a touch screen (mobile). I want to make that image "unclickable" or "inactive" or whatever, so that if a user touches and drags from that image, the page behind it still scrolls as if the image weren't there "blocking" the interaction. Is this possible? If need be, I could try to provide screen shots exemplifying what I mean. Thanks! 回答1: Setting CSS - pointer-events: none should remove any mouse interaction

问题 I'm using the microsoft/BotFramework-WebChat, but I'm having problems getting it to scroll properly. Often when the bot responds the user is forced to manually scroll to the bottom of the chat log. I can't find any documentation about hooks that would let me call an API to scroll it.

Need any help?</p> <div id="bot-open"

问题 I'm trying to scrape all the links available in an infinite page, scrolling down and getting the new links available. However, time.sleep() does not allow to pause the driver for a reasonable time, before scrolling down again and again. Is there any way to adjust the code that you can find at the bottom to reduce the number of sleep during the first iterations (when the page still loads the new content fast) and wait for the necessary time for the next iterations (when the page will load the
