console.log

I have a string of maybe 20 or 30 lines i'd like to output to the console all in one console.log call. This works great in Chrome, but IE11 truncates about half of the string in the console. Any way to prevent this? The string is something like: ----------------------------------------- Wed Jan 7 20:41:16 GMT-0700 2015 530d8aa855df0c2d269a5a5853a47a049c52c9d83a2d71d9 ----------------------------------------- 41:17:181 - Initiating recording... 41:17:233 - Creating NetStream... 41:17:240 - NetStream created. 41:17:240 - Recording ready. ----------------------------------------- Wed Jan 7 20:41

Twitter’s website does something like console.log = function () {}; to turn the browsers’ built-in console.log method into a no-op. Is there I way to restore the original function? Unless they also removed it in the prototype, getting the log method using getPrototypeOf() should work: console.log = Object.getPrototypeOf(console).log; Since using console.log = function() {} overrides, but doesn't remove the one defined in the prototype, you can delete the overriding method: delete console.log 来源： https://stackoverflow.com/questions/32801652/how-to-restore-console-log-on-a-web-page-that

I need to capture the console logs (category: info) of a browser using Ruby & Capybara. Until now I have tried using driver.manage.logs.get(:browser) or ( :client) but, using this, the result is not what I want. It gives out the interaction results between selenium and browser where I can see my javascript statements sent for execution, but the resulting output fails to get captured. Whether or not logs are available when using selenium depends on what browser you are using with Selenium. If you were using Firefox you'd be out of luck since it doesn't support the log retrieval API, however

I remember that always when I wanted to pass console.log as a callback parameter to some function, it didn't work unless I used the bind() method to bind console to it. For example: const callWithTest = callback => callback('test'); callWithTest(console.log); // That didn't use to work. callWithTest(console.log.bind(console)); // That worked (and works) fine. See Uncaught TypeError: Illegal invocation in javascript . However, recently I noticed that console.log() works fine even when called on object other than console. For example: console.log.call(null, 'test'); logs 'test' . When and why
