I want to do the loading work in background page, but I don’t how to program.

Answer 1

You can do you loading in background page.

function load_data() { 
    // do something 
}

and then call it in your option page.

var app = chrome.extension.getBackgroundPage();
app.load_data();

then your loading process will keep running in the background.
