  setting the readOnly Attribute is not working in JS

  Jan 21, 2013 10:45 PM|LINK

  Hi all

  I'm having a problem trying to set the readOnly property of a TextBox from Javascript. My HTML code is:

  <asp:TextBox ID="txtNoControl" runat="server" Width="40" CssClass="small" ReadOnly="true"></asp:TextBox>

  And my JS code:

  document.form1.txtNoControl.setAttribute("readOnly", false);
  document.form1.txtNoControl.removeAttribute("readOnly");
  document.form1.txtNoControl.readOnly = false;

  None of the JS codes seem to work for me :-( I've google it and in most of the pages those lines of codes are mentioned. However, for me is not working. I'm using IE 7

  Is there any wrong in the code? what would be a solution for this?

  I appreciate your help

  Regards!

  you are on the right track. Here you go using jQuery

  and then with JS Method added

  document.getElementById('txtTest').setAttribute('readonly', true);
