Read cookie using JavaScript Code

Read cookie using JavaScript Code

Today, we'll look at how to use JavaScript code to read cookies. The function readCookie, which is located below, accepts a cookie's name and returns its value.

function readCookie(name) {
  var nameEQ = name + "=";
  var ca = document.cookie.split(';');
  for(var i=0;i < ca.length;i++)
    {
     var c = ca[i];
     while (c.charAt(0)==' ')
     {
      c = c.substring(1,c.length);
     }
    if (c.indexOf(nameEQ) == 0)
     return c.substring(nameEQ.length,c.length);
    }
  return null;
}

I will demonstrate how to generate cookies using JavaScript in the code below.

function cookieCheck(){
  var interval;
  if(readCookie("userlogTime") == null)
  {
   var cDateTime = new Date();
   var timeSet = cDateTime.getHours();
   document.cookie ="userlogTime="+timeSet;
   }
  }
The above code show how we can create cookie using javascript
