breakpoints

I would really love to be able to see the code that is affecting a specific DOM element. But I also would really love not to have to look through all my javascript searching for references/selectors that might be causing the issue. Does anyone have a technique for causing a browser debugger to break on any changes to a specific DOM element? I don't mind it requiring a specific browser or extension to work. This is also doable without writing any script in Firebug as well as in Chrome's developer tools (maybe others, did not inspect further). In Firebug: Go to HTML tab Right-click an element

Is it possible, in any browser, using any plugin, to enable or disable breakpoints in your code programmatically? I already know about setting conditional breakpoints, but I'm really interested in setting them via code. First you could add a call to a function like __checkDebug(); which will check for a global (or semi-global) variable and when said variable is true, call debugger. function __checkDebug() { if (debugme) debugger; } all of your functions you're concerned about debugging would be like so: function foo() { __checkDebug(); //.... whatever foo was gonna do. } You can then take it a

When a breakpoint is hit in Visual Studio, it steals the focus from whatever other application the programmer is viewing/typing into at that moment. This can be very irritating since VS grabs any keyboard input the programmer was typing into the other application at that moment and takes that input as its own. What are the tricks you folks use to prevent this focus steal? (I face this on Visual C++ 2008 and 2010. I am guessing it is a problem for Visual Studio in general and for all recent versions.) This is a registry setting. See ForegroundLockTimeout at http://technet.microsoft.com/en-us

I'm looking for a way in .NET (2.0, C# in particular) for source code to trigger a debugging break as if a breakpoint was set at that point, without having to remember to set a specific breakpoint there in the debugger, and without interfering with production runtime. Our code needs to swallow exceptions in production so we don't disrupt a client application that links to us, but I'm trying to set it up so that such errors will pop up to be analyzed if it happens to be running in a debugger, and otherwise will be safely ignored. My attempt to use Debug.Assert(false) has been less than ideal,

I got a bogus value of finalScore , what happened? I want to know why finalScore is 4339953456 rather than a correct number 520 . Your breakpoint is on the finalScore = line, it means that the program is stopped before this value has been computed. It should show no value instead of a bogus value, probably, but this is not something that you have to worry about: set your breakpoint one line later and your finalScore will have a proper value. 来源： https://stackoverflow.com/questions/37816724/get-bogus-value-when-execute-break-point-in-a-variable

How can I find out which line will be executed after performing any action? If I know what will be executed I can put break point there. But what if I am not sure where to set breakpoint or just I need to go to the executing line faster (without setting breakpoints). "Break All" is not what I look for. It is pausing debugging, so I cannot perform any action (just after which I want Visual Studio sets breakpoint automatically) In other words, for example I want to start debugging each line after clicking a button, without putting breakpoints. Is it possibile? For a .NET application you can use
