问题 I would like to change the tooltip text of of Chrome's Element Inspector. (The one you see within the page when hovering a node in the tree view). I want to add additional information there. Is this somehow possible? I could not find any information in the docs. Alternatively creating a new little tooltip at another corner of the highlight rectangle (which will not interfere with the existing one) would be fine too. Thanks for any hints & tips. 回答1: So the answer is basically "you can't do

问题 I have the following code: var constructors=[]; var counter = 0; function start() { for (var i=100; i> 0; i--) { constructors.push(new arrayValues()); } if (counter < 10) { setTimeout(function() { start(); }, 1000); } counter++; } function arrayValues() { this.values = new Array(10000000).join("x"); } Which creates dummy array and creates memory leaks.

DevTools lists Data URIs as originating from memory cache, even on a brand new Chrome profile. So it's a bug. Try these: Clear Storage pane Empty

问题 I don't want to just filter the console outputs, but search for string in it (showing or collapsed) as well. Is it possible? CTRL+F cannot search inside collapsed outputs. For example, if the output is an Array[3] , it's shown as a collapsed tree. Even if you click to expand to show details about the array, you can't search in there. 回答1: The Filter text box now searches inside of collapsed output. For example, in the screenshot below you can see that the POST error with the expanded output

问题 I would like to find a way to explore Array objects in the chrome console (and even other console like firebug ), as we can easily do for other objects. Below is the snippet I entered in the chrome console : var str = new String("foo"); str; var bool = new Boolean(true); bool; ["foo", "bar", str, bool, {}]; And the results in the chrome console : The only way I could find at the moment is kind of a hack : [["foo", "bar", str, bool, {}]]; Is there any option, command or method to just show the

问题 My Chrome developer tools are great and I love them. I'm experiencing a woe lately though. Somehow I turned on some sort of break-on-error and I don't know how to turn it off. I've looked on google but it's tough because I don't know the correct term for what's happening so I thought I'd give SOF a try. Thanks all. 回答1: Go to the Sources tab, and locate the button at the bottom with two stripes on it. Click on this button to switch between the following states: "Don't pause on exceptions"

问题 Is there a way to get document and window properties in the chrome developer toolbox? I don't see it in the element tab of the developer toolbox.

问题 I'm building a developer-themed browser in a C# .NET Windows Form Application and want to allow users to use Chrome or Firefox DevTools to edit/debug the current page they are viewing .
