Found the answer some some of my problems, html5 web workers!!!
How do I pass an argument to a web worker though using this basic example?
contents of worker.js:
function doSomething() {
postMessage(开发者_Python百科 ' done');
}
setTimeout ( "doSomething()", 3000 );
js code:
var worker = new Worker('worker.js');
worker.onmessage = function (event) {
alert(event.data);
};
As you can see you have the same mechanism for both worker-to-main and main-to-worker messages.
- the
postMessage
method for sending messages - the
onmessage
member for defining the handler that receives the messages
In the main script:
worker.postMessage(data);
In the worker script:
self.addEventListener("message", function(e) {
// the passed-in data is available via e.data
}, false);
... or just...
onmessage = function(e) {
// the passed-in data is available via e.data
};
It may be that data has to be a string... (Firefox 3.5+ supports passing in JSON-compatible objects)
var worker = new Worker(window.App.baseUrl + '/Scripts/signature/GetCurrenProductWorker.js');
worker.postMessage(window.App.baseUrl)
var _base_url = ''
var xhr = new XMLHttpRequest();
onmessage = function (e) {
_base_url = e.data
xhr.open("GET", _base_url + "/api/product/Get");
xhr.onload = function () {
postMessage(xhr.responseText);
};
xhr.send();
};
this work for me
