Unable to import poly2tri.js script in web worker script. #35

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create Web worker script.
2. Use importScripts() to import poly2tri.js in onmessage() of worker.
3. In chrome (on F12), you can see the error as "Uncaught ReferenceError: 
window is not defined"

What is the expected output? What do you see instead?
Script should get loaded. But failing to load script.

What version of the product are you using? On what operating system?
Windows 7, Google chrome 16.0.912.63 m

Please provide any additional information below.
Please see the below code for main script and worker script.

//main script file.

//callback function for web worker.
function callback(event) {
    console.log(event.data);
}
var w = new Worker('task.js');
w.onmessage = callback;
w.postMessage("Hi"); // call worker.

//task.js file
self.onmessage = function(event) {
    importScripts('poly2tri.js'); // load the poly2tri utility.
    this.postMessage("Hello");
};

I am unable to find use of "window" object in poly2tri.js file :( 
Is there use of "window" object for this utility ?

Sorry the actual error is "Uncaught ReferenceError: Namespace is not defined"

I'm sorry the javascript port was not written by any of the authors of this lib 
but simply ported by a user. So can't really help you since I've never worked 
with javascript myself.

You might try to ask the original javascript porter if he have any insights.

got workaround for this:
remove the use of "Namespace"; instead use like MyNameSpace = MyNameSpace || {};
this solves the issue.
