问题 Is there a way to find out which JS script created a dynamic element in Chrome's Developer Tools? If I do 'view page source' on the page, the element isn't there. I can see the element though in Chrome's Developer Tools. Is there a way to find out specifically which JavaScript file and what line in my JavaScript file created the element?

问题 I am using the remote debugger inspector by visiting for example: http://localhost:9222/devtools/inspector.html?ws=localhost:9222/devtools/page/33767d5c-6abf-4c79-b8e7-d3b0c251fcaa The inspector works other than not being able to copy within the element, for copying xpath/sizzle selectors for instance which is really important . But on copy I am getting: Clipboard is not enabled in hosted mode. Please inspect using chrome://inspect I am remote debugging using an "external" inspector in google

问题 I have this situation and I am interested to know what can I do, in order to have a smooth menu sliding movement, all the way to the right (at menu-open) and to the left (at menu-close) without that jiggling interrupted-sticky effect at the beginning and the end of the movement that sometimes is covering the body site wrapper; I've tried to apply a smooth transition but the issue is still there: #responsive-menu-pro-button, #responsive-menu-pro-container, .edge-wrapper { -ms-transition-timing

问题 I'm debugging a GWT app using SuperDevMode in Chrome. What it gives me is the access to Java source maps in devtools. My problem is that when I'm debugging the code I would like to evaluate some of the variables. My question is - is it possible to evaluate a variable from the source map? If not - is it possible to navigate from the source map to the compiled javascript code? 回答1: Closest I can get to this is "Store as global variable" (Chrome 75): It will get named something like temp1 in the
