javascript - Injected script execute twice in Chrome Extension -


this popup.js it's included in popup.html, trigger when click on browser action's icon.

chrome.tabs.query({     active: true,     currentwindow: true }, function (tabs) {     var tabid = tabs[0];      chrome.tabs.update(null, {         url: 'https://example.com/login.php'     }, function () {          chrome.tabs.onupdated.addlistener(function (tabid, changeinfo, tab) {             if (changeinfo.status == 'complete') {                 chrome.tabs.executescript(null, {                     file: "jquery.js"                 }, function () {                     chrome.tabs.executescript(null, {                         file: "setlogin.js"                     });                 });              }         });     });

i have alert() within setlogin.js, have no idea why execute twice. expect trigger once have set execute script within changeinfo.status == 'complete' block.
