How to Create Free Webpage Hit Counter using Javascript?

In this post I am gonna show you how to create your own free Webpage hit counter for your website. Many of newbies or website developer use hit counter available on internet provided by some website,But It slows down your page loading. Hit counter created using "localStorage" in javascript is far better than cookies or any ready made counter. Count will increase even if you close browser window and next time you refresh page

Copy the code given below into script tag and refresh the page to count:



if (localStorage.pagecount)
 {
 localStorage.pagecount=Number(localStorage.pagecount) +1;
 }
else
 {
 localStorage.pagecount=1;
 }
document.write("Visits: " + localStorage.pagecount + " time(s).");

If you want to count page view for session of your browsing you can use "sessionStorage". It will increase count until you close your browser.


Copy the code given below into script tag and refresh the page to count:


if (sessionStorage.clickcount)
  {
  sessionStorage.clickcount=Number(sessionStorage.clickcount)+1;
  }
else
  {
  sessionStorage.clickcount=1;
  }
document.write("You have clicked the button " + 
        sessionStorage.clickcount + " time(s) in this session.");
