Log error to console with Web Workers in HTML5
Here is an example of an error handling function in a Web Worker JavaScript file that logs errors to the console.
Example
With error handling code, above example would become like the following:
<!DOCTYPE HTML>
<html>
<head>
<title>Big for loop</title>
<script>
var worker = new Worker('bigLoop.js');
worker.onmessage = function (event) {
alert("Completed " + event.data + "iterations" );
};
worker.onerror = function (event) {
console.log(event.message, event);
};
function sayHello(){
alert("Hello sir...." );
}
</script>
</head>
<body>
<input type = "button" onclick = "sayHello();" value = "Say Hello"/>
</body>
</html>
