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.


With error handling code, above example would become like the following:

      <title>Big for loop</title>
         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...." );
      <input type = "button" onclick = "sayHello();" value = "Say Hello"/>
