  How can you do this in javascript:

  For i = 1 To Len(str)

              hex_str = hex_str + LCase(CStr(Hex(Asc(Mid(str, i, 1)))))

  Next

  I don't know javascript well enough to convert myself

  var result="";

   for(var i=0; i<str.Length i++)

  (

    var str = Asc(Mid(str,i,1));

    var hex =str.toString(16);

    result = result + hex.toLowerCase();

  )

  function Asc(String) { return String.charCodeAt(0); }

   function Mid(str, start, len)
          
          {
                  // Make sure start and len are within proper bounds
                  if (start < 0 || len < 0) return "";
  
                  var iEnd, iLen = String(str).length;
                  if (start + len > iLen)
                          iEnd = iLen;
                  else
                          iEnd = start + len;
  
                  return String(str).substring(start,iEnd);
          }

  I try this, but the for loop is not executing. The format date takes this format 112:07:13-14:35:30. Here is the script where the for loop is not placing value in hex_str variable.

  <script type="text/javascript">

   function SubmitBtn() {

   var formattedDate = getFormattedDate();

   var chargetotal = document.getElementById("total").value;

   var storename = getStoreName();

   var timezone = getTimeZone();

   var sharedsecret = getSharedSecret();

   var str = storename + formattedDate + chargetotal + sharedsecret;

   var hex_str = "";

   for (var i = 0; i < str.Length; i += 1 ) {

   var str = Asc(Mid(str, i, 1));

   var hex = str.toString(16);

              hex_str = hex_str + hex.toLowerCase();

           }

          alert(hex_str); //this displays nothing

       function Asc(String) { return String.charCodeAt(0); }

       function Mid(str, start, len) {

       // Make sure start and len are within proper bounds

       if (start < 0 || len < 0) return "";

       var iEnd, iLen = String(str).length;

       if (start + len > iLen)

                  iEnd = iLen;

       else

                  iEnd = start + len;

       return String(str).substring(start, iEnd);

          }

          document.getElementById("chargetotal").value = chargetotal;

          document.getElementById("subtotal").value = chargetotal;

          document.getElementById("storename").value = storename;

          document.getElementById("timezone").value = timezone;

          document.getElementById("txndatetime").value = formattedDate;

          document.getElementById("sharedsecret").value = sharedsecret;

          document.getElementById("hash").value = SHA256(hex_str);

       }   

  </script>
