Looping in window.location

June 8, 2023

I am getting lat and lng from sessionStorage and I want to send it to browser with window.location but i get to a infinity loop.

    var lat = sessionStorage.getItem('lat');
    var lng = sessionStorage.getItem('lng');       
    window.location = '?lat='+lat+'&lng='+lng;

I saw other questions about this but they did not work.
I tryed to use window.location.hash / href etc… but the result is not what I expect

Does someone knows how to build that function to work properly?
Thank you very much

>Solution :

Here is a self invoked function to achieve what you want

const redirect = (() => {
  var lat = sessionStorage.getItem("lat");
  var lng = sessionStorage.getItem("lng");
  const params = new URLSearchParams(window.location.search);
  !params.get("lat") ? (window.location.href = `?lat=${lat}&lng=${lng}`) : null;
})();
