Some nice tips in here. I had no idea multiple cursors were supported. I now live in the future!

Would be good to know the cross-platform support for these features without testing them though. No "cmd" key in Linux :( (though, the ctrl key works as expected)

jefkoslowski7• 12 years ago

Thanks for your feedback, I will do that.

The second item, Command + Click on CSS, isn't showing your example image: http://devtoolstips.com/image/99439992616

This is on both Safari and Chrome on OS X.

Thats odd. Removed for now, I will create a smaller gif or video. Thanks.

jefkoslowski7• 12 years ago

Just uploaded a new smaller gif, it's working now.

monitorEvents is really awesome.

Would really like a little writeup on each of these to accompany the gif, couldn't quite figure out the "copy an object to the clipboard" one.

jefkoslowski7• 12 years ago

Thanks, I will work on it.

In general, some very brief text describing things beyond just an animated GIF would be really helpful. I spent a long time watching the eyedropper one over and over, trying to figure out what exactly you did to get the eyedropper to show up. It doesn't help that this is apparently a feature that's only in canary for now (I'd avoid that, or at least call it out explicitly), but even ignoring that, trying to get instruction by watching a dot flick around unpredictably in a screenshot is difficult/inefficient.

edit: great idea for a site, though. I've subscribed to your RSS.

Yeah, me too. Ever since I learned to read I've found myself relying less and less on video tutorials ;-)

The copy to a clipboard has a few elements to it.

1. If you right click on an object in the console, you can store it as a global variable. This makes an exact copy of the object that is in the global scope.

2. They used $_ which is a shortcut to get the result of the last command. So in the example, temp9 was the last command, so $_ is a copy of temp9

3. The important bit is the copy(var) call. This will copy any var into your clipboard!

Hopefully this was helpful!

Why does this page use .gifs instead of HTML video? :'(

jefkoslowski7• 12 years ago

Sorry about that. I will try to convert everything to video on the next week.

You can also try using gfycat.com to do this automatically.

Chrome Devtools has basically become my main tool when I do web development. I honestly can't imagine what I did before Chrome was around.

billyhoffman• 12 years ago

You probably used Firefox + Firebug and couldn't believe you used to do development without them.

Before Firefox + Firebug though? Well, you probably have suppressed the memories about using alert() calls for debugging through your tears. :-)

JeremyMorgan• 12 years ago

You nailed it.

alert("1"); alert("2"); alert("we got here");

Ah, I don't have fond memories of those days.

I didn't know about monitorEvents, it's really nice! This link has more details about what events you can monitor.

Nice.

FYI: I infrequently post some of these tips to Google+: https://plus.google.com/+UmarHansa with detailed descriptions. Also on Twitter: https://twitter.com/umaar with less description.

My personal favorite is debug(function_name). Creates a breakpoint at the beginning of the function. I use it almost daily.

tobeportable• 12 years ago

I don't see a way to suggest a tip or trick.

My ah ha moment was when i discovered the usage of :' debugger; ' in a.js with inspector open

jefkoslowski7• 12 years ago

Added to my todo list, thanks.

ufmace• 12 years ago

That one where you click on the curly braces to auto-de-minify is awesome!

lobster_johnson• 12 years ago

Anyone know of a better way to get proper JSON out of something emitted to the console? The "store as global variable" + copy($_) is ridiculous.
