the throw to also send or mail the exceptions, but I didn't find this to be possible. 1:main solution to this, a window.onerror handler: window.onerror = function(e, url, line){ mailError('onerror: ' + e + ' URL:' + url + ' Line:' + line); console.error('\nLine ' + line + ':'); setTimeout(function(){retry();}, 100); //mainly useful in content scripts for extensions, return true; } May also need to do same thing via jQuery: $(window).error( function(e, url, line){ //handle error } ); The downfall of this is that your code has stopped executing. To avoid errors stopping execution, it's best to use callbacks to make sure code executes in a certain sequence, and to utilize events wherever possible. You can also protect dom calls with a few techniques $(document).ready({ //you usually won't get bad dom calls wrapping your code in this }); You can also consider running code on window.onload window.onload = function(){ //you page will probably twitch upon executing code at this time //but you will almost never have a bad dom call }; Another technique if (document.getElementById('iNeedThisElement')) { //doin work! document.getElementById('iNeedThisElement').style.display = 'block'; } e

It uses some jquery in the user side (themes) as a jquery plugin. The problem is, when there is an javascript error with other plugins made by other autors, my plugin's javascript fails http://stackoverflow.com/questions/12219154/ignore-javascript-syntax-errors-in-a-page-and-continue-executing-the-script to execute. And the worst thing is people consider that there is a serious fault with my plugin even though it works 100% fine with error handling conditional statements. But it is actually due to some other javascript syntax errors of some other WP plugin/theme authors. Is there a way to continue execute my plugin JS ignoring other JS errors. Or can i have suggestions to handle this problem ?? javascript jquery html wordpress plugins share|improve this question edited Sep 18 at 23:16 Ciro Santilli 烏坎事件2016六四事件 法轮功 52.2k10222166 asked Aug 31 '12 at 16:20 Aakash Chakravarthy 3,145114463 3 You wish, but there's always try/catch ?? –adeneo Aug 31 '12 at 16:21 16 You cannot catch what's not yours. –raina77ow Aug 31 '12 at 16:26 9 @raina77ow - You should make dev-themed fortune cookies. –Richard JP Le Guen Aug 31 '12 at 16:27 @raina77ow - you got that right, LOL!

Source Firebug Lite Extensions Firebug and Errors When things go wrong, Firebug lets you know immediately and gives you detailed and useful information about the errors in JavaScript, CSS, and XML. Firebug Start Button On the right side of the Firefox browser's tool bar you will see a little Firebug icon. This is Firebug's entry point (aka Start button). It can be used to open the Firebug UI, access basic commands or see whether there are any JavaScript errors on the page. No error soup Most browsers report errors by dumping them all into one big window that includes the problems with every web page you've ever visited. Firebug is kinder than that; it shows you only the errors for the page that you're looking at. Informative JavaScript errors JavaScript errors include a wealth of information about what went wrong, including a description, the file and line number, and the line of source code that caused the error. Even more importantly, if you click the arrow to expand the description you will see a complete stack trace including the values of all function arguments. Jump to the debugger Every error report has a link on its right side that points to the file and line number where the error occurred. Clicking this link will take you right to the Firebug JavaScript debugger or CSS inspector so that you can get started on solving the problem right away. Some errors also include the actual snippet of source that contains the error, which is also a link to the original file. Quick search Using the quick search box, you can filter the Firebug Console to show only the errors and messages that match the text that you searched for. As new rows are added to the console, they will only appear if they match the text in the quick search box. Filtering errors Firebug is capable of reporting errors in JavaScript, CSS, or XML files.
