javascript - URL Redirect for Auth

Question

My login page goes to mywebsite.com/dashboard.html?fromauth but if it does it without the ?fromauth I want to redirect them to the login page. The challenge is I cannot have a .htaccess due to provider restrictions

Answer 1

Change the URL to ?fromauth=1, and then you can use JavaScript to read the page URL:

var URLString = window.location.href;
var URL = new URL(URLString);
var fromauth = URL.searchParams.get("fromauth");
if (fromauth != 1){
    window.location.replace("http://www.mywebsite.com/login");
}
