Javascript：获取<img> src 并设置为返回“”地址？

Question

function getFavicon(){
     return "http://example.png"
}

This code is the only one that works for me. When I try to change the url within that to a code like " return "chrome.extension.getBackgroundPage().imageSrc[0]"" it shows nothing... can someone please help me?

Answer 1

try this.

function backgroundFunction () {
    return "http://example.png" 
}

(function () {
    var otherWindows = chrome.extension.getBackgroundPage();
    console.log(otherWindows.backgroundFunction()); 
})();
