问题 I have been trying to scrape all the reviews available at a single url by repeatedly clicking on the button 'Show 6 more reviews' . I believe this problem would apply to anyone scrapping many dynamic elements at a single url with Selenium. Problem: when the number of reviews is more than a few hundreds, the loop becomes very slow. I am using Selenium since the website involves Javascript. HTML of button I am clicking (towards bottom of page) <button type="button" class="css-1e0935c" data-comp

问题 I used the JQuery function scrollTop on a list of contact numbers in a click function for each letter. It scrolls to where it is supposed to but then scrolls back to the top immediately. Here is a sample of the function in the code: $('.a').click(function(){ $('html, body').animate({scrollTop:$('#A').position().top}, 'slow'); }); Here is the JSFiddle I made for it: http://jsfiddle.net/CR47/MdtSE/ 回答1: If you're adding this to an anchor tag, you normally need to add a preventDefault() or

问题 I'm writing some HTML so that I can draw a Bezier curve using the HTML SVG and PATH tags. My curve comes out really nice and now I want to add a capability where if a user hovers his/her mouse over the curve I change the color. What's happening though is that the SVG creates a large box that contains the path and it catches all clicks. It's essentially blocking everything underneath it, even in areas where the path is not present. Imagine that the path goes from the bottom left corner to the
