Human readable javascripts in chrome developer tools

狂风中的少年 提交于 2019-11-27 06:14:55
does anybody know whether Chrome Developer Tools can format javascripts into human readable form ? Some kind of beautifier would be handy. Let say that I'm using some JS library and I need to instantiate its object, so that I should know what to put into constructor. But searching through this huge library that has 4 lines in the Chrome Developer Tools user interface is quite annoying... Otherwise the server side needs to take care of implementing "dev mode" that supplies javascript files that are not minified ... fgm2r Some browsers have a Pretty print button that looks like this {} and it

Chrome Dev Tools: <page context> and <top frame>?

问题 What do these drop downs do? I assume they execute console commands in different contexts but I see weird, nonsensical choices when I click them. 回答1: Lets take Gmail as an example and start by looking at the first drop down: List of frames What you can see here are all frames that are embedded into the current page. Each of these frames is sandboxed. Being sandboxed means that there is no access from one sandbox to the other sandboxes. Scripts executed inside one frame can't access DOM or JS

What do the crossed style properties in Google Chrome devtools mean?

孤者浪人 提交于 2019-11-27 05:58:25
While inspecting an element using Chrome's devtools, in the elements tab, the right-hand side 'Styles' bar shows the corresponding CSS properties. At times, some of these properties are struck-through. What do these properties mean? When a CSS property shows as struck-through, it means that the crossed-out style was applied, but then overridden by a more specific selector, a more local rule, or by a later property within the same rule. (Special cases: a style will also be shown as struck-through if a style exists in an matching rule but is commented out, or if you've manually disabled it by

How to use Chrome's network debugger with redirects

北城余情 提交于 2019-11-27 05:53:57
The Chrome network debugger gives me a great view of all the HTTP resources loaded for a page. But it clears the list whenever a new top-level HTML page is loaded. This makes it very difficult to debug pages that automatically reload for one reason or another (running script or 300 responses). Can I tell Chrome not to clear the network debugger when a new top-level page is loaded? Or can I go back and look at the previous page's network resources? Or can I somehow force Chrome to pause before loading a new page when I don't control the page I'm trying to debug that's doing the redirecting? It

View list of all JavaScript variables in Google Chrome Console

In Firebug, the DOM tab shows a list of all your public variables and objects. In Chrome's console you have to type the name of the public variable or object you want to explore. Is there a way - or at least a command - for Chrome's console to display a list all the public variables and objects? It will save a lot of typing. Nick Craver Is this the kind of output you're looking for? for(var b in window) { if(window.hasOwnProperty(b)) console.log(b); } This will list everything available on the window object (all the functions and variables, e.g., $ and jQuery on this page, etc.). Though, this

How to search all loaded scripts in Chrome Developer Tools?

白昼怎懂夜的黑 提交于 2019-11-27 05:45:25
In Firebug, you can search some text and it will look for it in all scripts loaded on a page. Can the same be done in Chrome Developer tools while debugging client script? I tried it, but it seems to search only in the script I have open, and not the rest that are on the page. I hope the next screenshots give a better idea about what I'm trying to accomplish: The following screenshots are from a single search in Firebug: vsevik Open a new Search pane in Developer Tools by: pressing Ctrl + Shift + F ( Cmd + Option + I on mac) clicking the overflow menu ( ⋮ ) in DevTools, clicking the overflow

How to block a URL in Chrome's developer tools network monitor

一世执手 提交于 2019-11-27 05:31:29
问题 I am currently analysing my page connections and I want to block some tracking scripts and other external URL calls in my network monitor inside Chrome's developer tools. I quickly want to check how the page behaves without some libraries. Chrome itself does not provide any functions like this and the famous blocking extensions only block URLs which the user enters manually into the navigation bar. 回答1: As pointed out by @calavera.info, @iman.Bahrampour, and @Asim K T this feature is now

Why is my json file not found?

给你一囗甜甜゛ 提交于 2019-11-27 05:20:42
问题 I have a json file in a Content folder within my asp.net project: <projectName> \Content NBCCJr.json ...and the code to access it: $.getJSON('~/Content/NBCCJr.json', function (data) { $.each(data, function(i, dataPoint) { // Bla }); }); ) ...but nothing happens when the code is called; the browser console says, "Failed to load resource: the server responded with a status of 404 (Not Found)" Why is it not found? Isn't "tilde whack filename" the correct route to the file? UPDATE I also tried it

What is “(program)” in Chrome debugger’s profiler?

馋奶兔 提交于 2019-11-27 05:20:28
问题 What is “(program)” in the function column of the Chrome debugger? 回答1: (program) is Chrome itself, the root of the tree calling all other code...it's there because the jump from native code to JavaScript, resource loading, etc. has to start somewhere :) You can see examples of the treeview in the Chrome developer tool docs. 回答2: I believe (program) is native code, not the root of the tree. See this thread: https://bugs.webkit.org/show_bug.cgi?id=88446 So, more like system calls than like

Load chrome extension using selenium

你离开我真会死。 提交于 2019-11-27 05:17:57
All I want is to load a chrome extension from web store. I do a lot of search to figure it out, but only got to know we can load extension from local machine. I really wonder if selenium does not have the functionality to load extension from web store or from a URL. Please let me know what I am trying is possible using selenium ? I am not sure why you are particular about downloading from Webstore and then install into Chrome. I found some steps to download chrome extensions: -With a computer connected to the internet, install the extension from the extension page: https://chrome.google.com
