Question

I have been reading up on HTML 5 worker threads but all the samples i have seen seem to require the javascript be in its own file.

so im basicly wondering if its posible to start a worker work directly towards a function.

The end goal here being something along the lines of:

function AllJavascriptIsLoaded()
{

if(gWorkersSupported)
{

        var Worker = new Worker(MyFunc)

        Worker.Start();
    }
    else 
    {
        // Horrible user experience incomming.
        MyFunc();
    }
}

function MyFunc()
{
    // Complex and time consuming tasks
}

Answer 1

To my knowledge, this is not allowed for security reasons. I’d assume that a child object, or any JS script in the same file, would potentially have access to the parent DOM window, which Web Workers are not allowed to access.

So, we’re stuck with posting messages to other files unless someone finds a nicer way to do it 😉
