how to run javascript function after location.reload() in same browser window

I have simple function;

    setTimeout(function(){ alert('hello');  
         //Business stuffs..
         location.reload();
         eval(localStorage.getItem('mysc'))},5000)

after open in a browser(chrome or firefox) I type this;

localStorage.setItem("mysc","setTimeout(function(){ 
    //Business stuffs...
    location.reload();
    eval(localStorage.getItem('mysc'))
    },5000)");

After that once I type; 

eval(localStorage.getItem('mysc'))

I want this function executes in same browser window forever.. or till close the browser.. but as you guess, it only works once. How can I achieve this ?

You should create the timer on page load, and reload the page in the callback. When the page reloads, the timer will be re-created. This will "recursively" reload the page every 5 seconds.

<html>
  <head>
    <script type="text/javascript">
      console.log('page loaded, waiting...');
      setTimeout(function () {
        console.log('reloading');
        location.reload();
      }, 5000);
    </script>
  </head>
</html>

As far as I know, there is no way to achieve this if you don't control the page you want to reload (i.e., using Dev Tools or console APIs). It's impossible to attach a script to execute on the next page load, and any active timers are cleared when the current page unloads. A browser extension is probably the way to go; for example, Content Scripts can be used to achieve this in Chrome.
