Changing a textbox to "non-required"

[crocboy25]

Group,

I have a textbox set to required in model I am using as shown below:

<DisplayName("Last Name"), Required()> _
Public Property LastName() As String
Get
Return _LastName
End Get
Set(ByVal value As String)
_LastName = value
End Set
End Property


When a user checks a checkbox on the page, I want to make this
LastName textbox option(nonrequired) using JQuery. Is there a way
anyone knows how to do this? Here is some sample JQuery I am doing
during an event when the box is checked....

$('input[name="People_1__LastName"],
label[for="People[1]_LastName"]').hide();
$("#People_1__LastName").hide();
$("#People_1__LastName").val("hello");
$("#People_1__LastName :input").attr('disabled',
true);

Any help with this would be appreciated.

 <p id="phide">
                                                    <label for="Textbox_Lastname">
                                                        GuardianAddress:</label>
                                                    <%= Html.TextBox("Textbox_Lastname") %>
                                                    <%= Html.ValidationMessage("Textbox_Lastname", "*") %>
                                                </p>
                                                <p>
                                                    <label for="status">
                                                        Status:</label>
                                                    <%= Html.CheckBox("status") %>
                                                    <%= Html.ValidationMessage("status", "*") %>
                                                </p>



<script language="javascript" type="text/javascript">

 $('#status').click(function() {
            var thisCheck = $(this).val();
            alert(thisCheck);
            if (thisCheck) {
                alert("checked");
                 $('#phide').hide();
            }
        });
</script>

A few things...

To get the jquery call to happen on page load, you need to wrap with the document ready call:

$(document).ready(function() {

 $('#status').click(function() {
            var thisCheck = $(this).val();
            alert(thisCheck);
            if (thisCheck) {
                alert("checked");
                 $('#phide').hide();
            }
        });

});

Now, the function is bound to the click event..

Another thing...how about re-displaying the textbox (and simplyfying the code a bit too!!). I think this will work:

$(document).ready(function() {
   $('#phide').hide();
   $('#status').click(function() {
      if !($(this).val());
         $('#phide').show();
    }
});

Another way to handle these sort of requirements is through css styling. Instead of explicitly invoking show and hide (which behind the scenes is just doing the same thing with styles) - create your own styles and use jQuery to apply the styles accordingly.

No.

The answers you are getting are simple making the textbox appear and
disappear in the browser. This has no impact on the data validation that
will occur when the data are submitted back to the model.

Try again.
