One time page refresh after first page load

<script>

function reloadIt() {
    if (window.location.href.substr(-2) !== "?r") {
        window.location = window.location.href + "?r";
    }
}

setTimeout('reloadIt()', 1000)();

</script>

this works perfectly

Finally, I got a solution for reloading page once after two months research.

It works fine on my clientside JS project.

I wrote a function that below reloading page only once.

1) First getting browser domloading time

2) Get current timestamp

3) Browser domloading time + 10 seconds

4) If Browser domloading time + 10 seconds bigger than current now timestamp then page is able to be refreshed via "reloadPage();"

But if it's not bigger than 10 seconds that means page is just reloaded thus It will not be reloaded repeatedly.

5) Therefore if you call "reloadPage();" function in somewhere in your js file page will only be reloaded once.

Hope that helps somebody

// Reload Page Function //
                function reloadPage() {
                    var currentDocumentTimestamp = new Date(performance.timing.domLoading).getTime();
                    // Current Time //
                    var now = Date.now();
                    // Total Process Lenght as Minutes //
                    var tenSec = 10 * 1000;
                    // End Time of Process //
                    var plusTenSec = currentDocumentTimestamp + tenSec;
                    if (now > plusTenSec) {
                        location.reload();
                    }
                }


                // You can call it in somewhere //
                reloadPage();

You can make one verable once = false then reload your page with if else like if once == false reload page an make once true.

Here is another solution with setTimeout, not perfect, but it works:

It requires a parameter in the current url, so just image the current url looks like this:

www.google.com?time=1

The following code make the page reload just once:

 // Reload Page Function //
    // get the time parameter //
        let parameter = new URLSearchParams(window.location.search);
          let time = parameter.get("time");
          console.log(time)//1
          let timeId;
          if (time == 1) {
    // reload the page after 0 ms //
           timeId = setTimeout(() => {
            window.location.reload();//
           }, 0);
   // change the time parameter to 0 //
           let currentUrl = new URL(window.location.href);
           let param = new URLSearchParams(currentUrl.search);
           param.set("time", 0);
   // replace the time parameter in url to 0; now it is 0 not 1 //
           window.history.replaceState({}, "", `${currentUrl.pathname}?${param}`);
        // cancel the setTimeout function after 0 ms //
           let currentTime = Date.now();
           if (Date.now() - currentTime > 0) {
            clearTimeout(timeId);
           }
          }

The accepted answer uses the least amount of code and is easy to understand. I just provided another solution to this.

Hope this helps others.

React Hook worked for me.

import { useEffect, useState } from 'react';

  const [load, setLoad] = useState(false);

  window.onload = function pageLoad() {
      if (load) {
        window.location.reload(true);
        setLoad(false);
      }
    };

nothing work for me perfectly except this, -added to my JavaScript file-:

function LoadOnce() {
if (localStorage.getItem('executed') == 'false') {
window.location.reload()
localStorage.setItem('executed', true)
}
}

setTimeout(function () {
LoadOnce()
}, 100)

and in the previous page I wrote:

localStorage.setItem('executed', false)
