I would like to interact with the page I am building with the console open. Unfortunately, if I trigger an event on my page the Dev Tools switches from "Console" to "Sources" and says "paused in debugger." It's driving me bananas. Is there a way to deactivate it?
How to deactivate breakpoints
Just press Ctrl + F8. Alternatively you can click the related button next to the buttons controlling the debugger.
This way the execution won't stop. It is especially useful when you try to inspect websites not under your control that left breakpoints (debugger command) in the source code, that might have been done intentionally to prevent you from doing said inspection.
You likely have a Breakpoint set on an Event. To remove it:
Open Debugger (F12)
Click on the Sources Tab
Click on the Event Listeners Breakpoints accordion dropdown (on the right)
Unselect (untick) each event that you do NOT want to break on.
Check your DOM, XHR and Event Listener breakpoints, and ensure they're unchecked/inactive.
To stop the debugger in Chrome, the circled icon should be deactivated (which will turn it grey colored):

I am switching from debugging JS in Firefox to Chrome.
One thing that I am missing is this:
In Firefox I can see in the HTML see "[event]" that there is a custom event handler attached.
I think this preview is very handy.
In chrome I need to explicitly search for the event handler.
Is there a way to enable this feature (see event-handler in the tree) in chrome, too?
The feature you are looking for is available in google chrome dev tools
I have taken, the jobs links in stack overflow page itself, it has a click event handler, to see the event handler, select the Event Listeners tab in the right part(hilighted in Red) there is a possibility that it might be hiddent by >> , click to expand,
If the ancestor checkbox is checked please uncheck this, then you will get the clear view of for which event (e.g click) , on what element (e.g anchor tag), and on right side on which file with line number, click it to navigate there.
Hope this is what you are looking for.
it's available in chrome you can find it in developers option press
(CTRL+SHIFT+I) or F12
and then you will find tab named "Event Listener" in right hand upper corner if developer options is in full screen mode or else you'll find it it lower right corner.
And if you are unable to find that just simply find the >> symbol and click on it and select Event Listeners.
Here is the image for event listeners tab.
I think you can use getEventListners($0) api of chrome which gives the event listners of the particular selected element.
getEventListners($0) where $0 - The selected element in the DOM.
The console drawer can be added to the Elements tab by clicking on Esc key it will toggle the console drawer.Then in the console you can write getEventListners($0) as shown in the image.
As this is my first answer and don't have that much reputation as of now,it is not allowing me to directly add the image to the answer so I am really sorry for that. Please have a look at the image:

Is there a way to debug a specific function without knowing where it is?
For example you have a project that has 100 000 lines of code on a lot of files. To find some function that's triggered by some button you need to search a long time and then you put the break point. Is there some tools to do that when I click the button automatic to stop the debugger of Google Chrome?
On the right side of the Sources Tab look for Event Listener Breakpoints, expand the Mouse events, and select the click event, chrome will go into debugger mode every time there's a click event
You can check on the console tab what triggers your error, and what will be the files involved.
Here's an example on Chrome :
Chrome console example
On the left, you got the file involved (VM998 for example) and the corresponding line (3, for example).
Hope it helps.
Say i have an icon in a webpage and i would like to figure out what happens when i click that, how do i debug that with chrome debugger? Assuming that i have the non-minified code for the webpage.
i tried to do inspect element and attaching to event handlers which doesn help much.
<span id="__icon84" data-ui="__icon84" data-ui-icon-content="" class="UiIcon UiIconMirrorInRTL" style="font-family:'icons'"></span>
all i get is that the icon used is __icon84.
PS: i am new to JS.
Use the Event Listener Breakpoints sidebar pane in the Sources panel. Expand "Mouse" and check the "click" box. Then the debugger should break whenever you enter a "click" event handler.
I'm trying to stop a div animation on a site that i don't have control to. The main idea is to use kimono lab, to capture certain texts on the wevsite, But i can't move my mouse fast enough.
the site is : http://www.healthtap.com
i know i can write python code to just scrape the site. But i'm just curious on how to accomplish this using kimono and chrome's developer tools. I can disable javascript on the dev tools, but it will also disable the JS from kimono.
I think I understand the question, but I am not sure, so bear with me.
I believe you want to stop the slides so that you can use kimono:
Try using this in the console:
jQuery('.blue_buttons a:eq(0)').click();
That will simulate the click on the first slide button. Change 0 to 1, 2, 3, 4. and so on to get the next slides. I don't see any timeouts that would start the rotation again.
Open up the Developer Tools (F12 or right click somewhere blank and click “inspect”)
Click the three little dots in the top right corner, and then click settings (or just press F1 with the Developer Tools window selected)
Check “Disable JavaScript”
You can try to add Load breakpoint in Event Listener Breakpoints.
Go to Sources -> Event Listener Breakpoints -> Load -> load and tick this option.
I have various JS files included in an HTML page and am trying to debug when an event is being triggered. There is an issue in this app I'm helping out on where when the user presses the left or right arrows then the mousemove event is being triggered. In Chrome, I'm using the Developer Tools and am trying to find where this mousemove event is being triggered. In the Scripts tab of the Developer Tools, I have Event Listener breakpoints set for keyup and mousemove. When the page hits the breakpoints, both call stacks show jquery.js. How do I pinpoint and debug which element is triggering these events? I'd like to find a way to have the Developer Tools give me a line number of a file other than jquery.js.
Also, this issue only appears in Chrome for some reason.
