  validation of code factor

  Jan 27, 2017 11:27 AM|scala_1988|LINK

  I've to develop a javascript code for validation of code factor format. The input lenght should not be greater than 3 characters long. The last character must be either 'M' or any digit between 0-9. eg. 4M or 110 or 45
  The format of code factor is like this::
  1. only 3 characters long
        I've done this by adding maxlength
  2. if all three characters are digits than number must not be greater than 150
  3. if the last digit is M the number must be less than 12 i.e 11M or 4M but not 12M or 13M

  <asp:TextBox ID="txtcode" runat="server" AutoCompleteType="Disabled"  MaxLength="3" />

  Please help!!!

  Hi scala_1988,

  From your description and based on your needs, I  write some code for your reference.

    
      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
      <script>
          $(function () {
              $("#txtcode").change(function () {
                  var codevalue = $(this).val();
                  alert(codevalue);
                  var lastnumber = codevalue.substring(2);
                  var pretwonumber = codevalue.substring(0, 2);
                  alert(pretwonumber);
                  alert(lastnumber);
                  var reg = new RegExp('\\D')
                  if (lastnumber != "M" && reg.test(lastnumber)) {
                      alert(" The last character must be either 'M' or any digit between 0-9");
                  }
                  if (lastnumber == "M") {
                      var inttypevalue = parseInt(pretwonumber);
                      if (inttypevalue >= 12) {
                          alert("if the last digit is M the number must be less than 12 i.e 11M or 4M but not 12M or 13M");
                      }
                  }
              });
          })
      </script>
  
    <asp:TextBox ID="txtcode" runat="server"  AutoCompleteType="Disabled" MaxLength="3"></asp:TextBox>

  2. if all three characters are digits than number must not be greater than 150

  I am not clear about you need above. you could add code to above code based on you second requirement or provide more description about this.

  Best Regards
