Send message from web page to chrome extension's background script

chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
    alert("message received");
});
 
chrome.windows.create({
    type : 'popup',
    url : "http://yoursite.com/page.html",
    type: "popup"
}, function(newWindow) {
 
});
