Hi,

How to restrict validation for mandatory fields in javascript when they are hidden on a condition?

first name &last name fields visible in user profile page on one condition, and not visible on another condition. when they are not visible, then also java script validating these fields. How to restrict validation when they are not visible?

thanks in advance.

What I have tried:

Here is my code:

function validateEditPage() {

var fname = '<%=txtFName.ClientID %>';
var lname = '<%=txtLName.ClientID %>';

if (document.getElementById(fname) != null) {
var varFirstName = document.getElementById(fname).value;
if (varFirstName == "") {
ShowErrorMessage('Please Enter First Name');
document.getElementById(fname).value = "";
return false;
}
}
if (document.getElementById(lname) != null) {
var varLName = document.getElementById(lname).value;
if (varLName == "") {

ShowErrorMessage('Please Enter Last Name');
document.getElementById(lname).focus();
return false;
}
}

return true;
}

There is no such thing as "java script". Yes, I understand what you mean, but do you?

using visibility[^] and display[^] css properties you can check it is hidden or not.

try this

function validateEditPage() {
          debugger;

          var fname = document.getElementById(  '<%=txtFName.ClientID %>');
          var lname = document.getElementById( '<%=txtLName.ClientID %>');


          if (fname != null) {
              if (fname.style.visibility != 'hidden' && fname.style.display != 'none')
              if (fname.value == "") {
                  alert('Please Enter First Name');
                  fname.focus();
                  return false;
              }
          }
          if (lname != null) {
              if (lname.style.visibility != 'hidden' && lname.style.display != 'none')
              if (lname.value == "") {
                  alert('Please Enter Last Name');
                  lname.focus();
                  return false;
              }
          }

          return true;
      }
