Question

I have input box txtRefreshInterval which allow only integer.

<td><span class="sfFormlabel">Refresh Interval</span></td>
<td><input type="text"  id="txtRefreshInterval"/> </td>

I validate it like this.

 $('#txtRefreshInterval').keydown(function() {
                    if (isNaN($('#txtRefreshInterval').val())) {
                        //$("#lblError").html("<br/>Please Enter Integer Value.");
                        return false;

                    }
                });

It works fine.In html there is not any lblEroor.I want to append lblError if and only if input box have not integer through code.
append:

<label id='lblError'>

and display message.But I am not find correct way to append

<label>

after

txtRefreshInterval.

Thanks.

$('#txtRefreshInterval').keydown(function() {
                    if (isNaN($('#txtRefreshInterval').val())) {
                         $(this).after('<label id='lblError'>Error</label>');
                        return false;

                    }
                });
