<script type="text/javascript"> | |
window.onerror = function(msg, url, line, col, error) { | |
// Note that col & error are new to the HTML 5 spec and may not be | |
// supported in every browser. It worked for me in Chrome. | |
var extra = !col ? '' : '\ncolumn: ' + col; | |
extra += !error ? '' : '\nerror: ' + error; | |
// You can view the information in an alert to see things working like this: | |
alert("Error: " + msg + "\nurl: " + url + "\nline: " + line + extra); | |
// TODO: Report this error via ajax so you can keep track | |
// of what pages have JS issues | |
var suppressErrorAlert = true; | |
// If you return true, then error alerts (like in older versions of | |
// Internet Explorer) will be suppressed. | |
return suppressErrorAlert; | |
