Therefore, a
Console.log Ie10
call to console.log may result in an error, for example if it occurs on page load before you have a chance to open the dev tools. The winning answer here explains it in more detail. –SDC Jan 28 '13 at 15:31 add a comment| 17 Answers 17 active oldest votes up vote 221 down vote accepted Even better for fallback is this: var alertFallback = true; if (typeof console === "undefined" || typeof console.log === "undefined") { console = {}; if (alertFallback) { console.log = function(msg) { alert(msg); }; } else { console.log = function() {}; } } share|improve this answer answered May 11 '11 at 16:33 orange80 8,21884458 Thanks, this helped me a lot, nicely done –martinjbates Oct 2 '12 at 8:45 66 This is so impractical - how could you possibly debug a website with something that throws an alert for every call to console.log(). What if you have 10+ calls to log() in your code. What if msg is an object? Walter's answer makes much more sense, as a starting point. –Precastic Jun 22 '13 at 10:47 6 @Precastic: People will just stop using the browser :P –Amogh Talpalli

13, 200831 Share 0 0 As Shreesh mentioned in his blog, Internet Explorer 8 has a built-in JScript debugger. With Internet Explorer Developer Tools you get a light weight JScript debugger that is well integrated in the browser and available out of the box. This is an in-proc debugger making sure that you don’t have to launch a separate app. It has familiar Visual Studio feel and features like call stacks, watches, locals and immediate window. To get to the debugger just press SHIFT+F12, or click the developer tools icon in the command bar. After launching the Developer Tools, switch to the script tab. Before starting debugging you can browse the source code of the websites’ main page and also use immediate window to try out JScript code. You can start the debugger session by clicking on the ‘Start Debugging’ button. The debugger lets you debug even when debugging is disabled in Internet Options Control Panel. This will allow you to enable debugging only for the IE instance you are debugging. All other IE instances will still be in non-debug mode making sure that you don’t get script error dialogs. This will also make sure that debugging won’t have any performance hit on IE instances other than the one being debugged. Debugger will refresh the web page with your consent, in case debugging was previously disabled. If you want to avoid page refresh, you can enable debugging from Internet Options. After starting debugging, the script debugger provides you execution control. Similar to Visual Studio you can set breakpoints by clicking in the source viewer next to the line number. You can also use context menu or keyboard shortcut (F9) to set breakpoints on the script statement at the cursor location in source viewer. If you have multiple script statements in a line of code, you can set multiple breakpoints on that line and they
