显示登录屏幕如果用户未登录| jQuery的

Question

I try to display Login Screen in the spesific URL ('ads/audience-insights') If the user is not logged in. but no luck.

Can you correct my code? what's wrong?

if (window.location.href.indexOf('ads/audience-insights') != -1) {
    chrome.storage.local.get("cnt9", function(result) {
        if (result.cnt9 == null || result.cnt9 == -1 || result.cnt9 >= 40) {
            // show login screen
            showLoginScreen();
        }
    });
}

This code == user Not logged in yet..

result.cnt9 == null || result.cnt9 == -1 || result.cnt9 >= 40

You don't have to use chrome.storage or the callback function.

if (typeof(Storage) !== "undefined") {
  var a = localStorage.cnt9;
  if (a == null || a == -1 || a >= 40)
    alert("Not Logged In!");
}

You also do not have to check if the user is on a specific page as the code will not execute if they are not on said page in the first place.
