Webworkers importScripts function

[rfairweather]

Hello everyone,

I am attempting to create a page that has a webworker constantly finding gps locations.

I initiated the worker using this code:

Code: Select all

var worker1 = new Worker('Scripts/worker1.js');
         worker1.onmessage = function (event) {
               alert(event.data);
         };

and then in the Scripts folder, I created a js file called worker1.js which has the following code:

Code: Select all

importScripts('http://maps.google.com/maps/api/js?sensor=true' type='text/javascript');

function sendBack(message) {
   this.postMessage(message);
}

sendBack("sup");


The code without the importScripts line functions as expected, but with the line included it does not run. If I were to use the <script> tag in the index.html file, using the same url, it works fine as well. Am I not using the importScripts function properly?

its worth noting that it also does not work without the type= part removed either.

Thanks in advance!

type= should not be there.

The script you're trying to include uses 'window' and 'document' which are not available to workers.

Thanks for your reply.

I got the type= from http://code.google.com/p/pmrpc/wiki/PmrpcApiDocs

is there a known work around for having a script like that then? I can't exactly change anything in the google side script

I added a comment on that page.

Well you can't pull it in from a worker, you have to reference it from a normal <script> in the document. You can then post messages to your worker and let it do something and post the result back to the document.
