问题 From Visual Studio, I'm accustomed to a call stack showing up at any breakpoint. Does Chrome have a call stack feature where I can see what functions preceded my breakpoint? If not, is there a substitute (3rd party solution that works with Chrome?) that developers use to see what functions led to a breakpoint? Edit: to be clear, I was expecting the call stack to appear within the javascript console in Chrome. 回答1: I don't know what version of Chrome you're using. I'm using Chromium 17 and the

问题 I've got a bug that looks like it's caused by an Event handler being attached a click event: mxpnl.track_links("#pagebody a", "Click.body"); I'd like to watch to see how that Element's event handler is added (and when) I found it in the Chrome Debugger (Dev Tools) > Elements and choose Break on Attribute modifications.

问题 I know this is a broad question, but I think I'm missing something here. Is it possible for an attacker to cause damage to a site by simple using inspect element and editing the javascript and html? For example, it seems too easy for someone to change the maxlength of an input, and upload so much data that it could crash the server, I know that it is always good practice to check data at the server but it still seems too easy. Or another more potentially dangerous example is if the attacker

问题 I am trying to make my webpage mobile friendly. So, I am using Chrome DevTools to design a mobile version of my webpage. I have it the way I want it to look in DevTools. I uploaded it to my website & viewed it on a actual mobile phone & objects are not in the same places as they are in DevTools.

问题 With google chrome chrome dev, I am running a lighthouse Analysis for mobile. Lighthouse shows a 7.0 seconds delay for Largest Contentful Paint (LCP): I decide to dive into this and click on: "View original trace".

问题 I'm trying to check if the user's from Google Chrome has activate the flag #enable-javascript-harmony. I have no idea how to do it.
