Hi,
I wrote a project to test the worker by running a loop to post a message, it works. However, the memory is keeping increasing.
Here is my code:
default.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>worker</title>
<!-- WinJS references -->
<link href="//Microsoft.WinJS.0.6/css/ui-dark.css" rel="stylesheet">
<script src="//Microsoft.WinJS.0.6/js/base.js"></script>
<script src="//Microsoft.WinJS.0.6/js/ui.js"></script>
<!-- worker references -->
<link href="/css/default.css" rel="stylesheet">
<script src="/js/default.js"></script>
</head>
<body style="overflow: scroll;">
<button id="post">post</button>
<button id="cancelpost">cancel post</button>
<p id="output"></p>
</body>
</html>
default.js
// For an introduction to the Blank template, see the following documentation:
// http://go.microsoft.com/fwlink/?LinkId=232509
(function () {
"use strict";
var app = WinJS.Application;
var id = function (ele) {
return document.getElementById(ele);
};
app.postMessageToWorker = function (eventInfo) {
worker.addEventListener('message', app.processMessageFromWorker, false);
worker.postMessage(eventInfo);
};
app.processMessageFromWorker = function (event) {
var data = event.data;
switch (data.type) {
case 'optimizeAdjust':
break;
case 'applyEffect':
var p = document.createElement('p');
p.innerHTML = data.d;
id('output').appendChild(p);
break;
default:
break;
}
}
var worker = new Worker("/js/worker.js");
app.onactivated = function (eventObject) {
if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {
if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) {
// TODO: This application has been newly launched. Initialize
var interval = null;
id('post').onclick = function () {
var eventData = {
type: "applyEffect",
d: 'This allows for long-running scripts that are not interrupted by scripts that respond to clicks or other user interactions, and allows long tasks to be executed without yielding to keep the page responsive.'
};
interval = setInterval(function () {
app.postMessageToWorker(eventData);
window.CollectGarbage();
}, 500);
};
id('cancelpost').onclick = function () {
clearInterval(interval);
};
} else {
// TODO: This application has been reactivated from suspension.
// Restore application state here.
}
WinJS.UI.processAll();
}
};
app.oncheckpoint = function (eventObject) {
// TODO: This application is about to be suspended. Save any state
// that needs to persist across suspensions here. You might use the
// WinJS.Application.sessionState object, which is automatically
// saved and restored across suspension. If you need to complete an
// asynchronous operation before your application is suspended, call
// eventObject.setPromise().
};
app.start();
})();
worker.js
self.addEventListener('message', function (event) {
var data = event.data;
switch (data.type) {
case 'optimizeAdjust':
self.postMessage(data);
break;
case 'applyEffect':
self.postMessage(data);
break;
default:
break;
}
}, false);
