Calling a function on popup from background. (Google Chrome Extension)
Question
I'm working in a google chrome extension. I have a function in my popup.js that populates a table update_table . I want to call that function from my background.js that sends the important data. The problem is the the update_table on background.js is not define and if i copy the code into that file dont update the table on popup.html.
popup.js
function update_table(content, morecontent){
if (!document.getElementsByTagName) return;
tabBody=document.getElementsByTagName("tbody").item(0);
row=document.createElement("tr");
cell1 = document.createElement("td");
cell2 = document.createElement("td");
textnode1=document.createTextNode(content);
textnode2=document.createTextNode(morecontent);
<!-- ... -->
}
popup.html
<!doctype html>
<html>
<head>
<title>Popup Page</title>
<script src="./popup.js" type="text/javascript"></script>
</head>
<body>
<table border='1' id='mytable'>
<tbody>
<tr><td>22</td><td>333</td></tr>
<tr><td>22</td><td>333</td></tr>
</tbody>
</table>
</body>
</html>
background.js
chrome.webRequest.onCompleted.addListener(
function(request) {
update_table(request.type, request.url);
},
{urls: ["*://*/*"]},
["responseHeaders"]
);
background.html
<!doctype html>
<html>
<head>
<title>Background Page</title>
<script src="./background.js" type="text/javascript"></script>
</head>
<body>
</body>
</html>

Read this post , I just answer this for another person.
Your best bet it to look the chrome.extension.* API . I will be posting an example on GitHub some time tomorrow that I can show you.
Hope this helps.
UPDATE
Here you go. This is a socket script I created that allows continuous communication between a background page and a popup. There is an example provided in the README. I currently use this for an extension that passes up to 100 items per instance and it works perfect. :P
