Enable checkboxlist not working in IE, asp.net, jquery -

<asp:checkboxlist id="chklist" runat="server" enabled="false" >     <asp:listitem text="1" value="1"></asp:listitem>     <asp:listitem text="2" value="2"></asp:listitem> </asp:checkboxlist>  <asp:button id="btnfoo" runat="server" text="test" />  <script type="text/javascript" language="javascript">     $(document).ready(function () {         $('#<% = btnfoo.clientid %>').click(function () {             //var targetvalue = 2;             var items = $('#<% = chklist.clientid %> input:checkbox');             (var = 0; < items.length; i++) {                 //alert(i);                 //if (items[i].value == targetvalue) {                     items[i].checked = true;                     // break;                 //}             }              $('#<%= chklist.clientid%>input:checkbox').removeattr('disabled');                                                    return false;         })     }); </script> 

note: works in chrome, ff not in ie

its not wroking in ie8, here below code. checking checkboxes, keeps them disabled, solution please?

try using prop property instead of .checked:

$("#btn").on("click",function(){     $('input:checkbox').each(function(){      $(this).prop("checked", "true");     }); });

$("#btn").on("click",function(){     $('input:checkbox').each(function(){      $(this).prop("checked", "true").prop("disabled",false);     }); });
