Hi all,

Im hoping im missing something really simple here :).

I have the following code which is testing validation on textboxes; (please forgive the alerts)

<asp:TextBox ID="FirstNameTextbox" CssClass="half" runat="server" MaxLength="30"></asp:TextBox>

    <script type="text/javascript">
        $('#<%=FirstNameTextbox.ClientID%>').watermark('First name');

        $(document).ready(function () {
            $('#<%=FirstNameTextbox.ClientID%>').focusout(function () {

                if ($('#<%=FirstNameTextbox.ClientID%>').val() == "") {
                    alert('about to focus out');
                    highlightField($('#<%=FirstNameTextbox.ClientID%>'), false);
                    alert('finished!!!!');
                }
                else {
                    highlightField($('#<%=FirstNameTextbox.ClientID%>'), true);
                }

                alert('got here no issues');
            })

            $('#<%=FirstNameTextbox.ClientID%>').focusin(function () {
                if ($("#<%=FirstNameTextbox.ClientID%>").hasClass("error")) {
                    highlightFieldMessage($('#<%=FirstNameTextbox.ClientID%>'), false, "Please enter your first name in full.");
                    alert('here okkkk');
                }
             })
        });

        function highlightField(textfield, valid) {
            //alert('now here');

            if (textfield.parent().is(".textbox-wrapper")) {
               // alert( textfield.parent().html());
                textfield.parent().find(".input-status").remove();
                //alert('removed the status icon');
                //alert(textfield.parent.html());

                textfield.parent().find(".error-popup").remove();
                textfield.parent().find(".valid-popup").remove();
                //alert('removed any popups');
                textfield.unwrap();
                //alert('unwrapped');
            }

            //alert('adding the wrapper');
            textfield.wrap("<div class='textbox-wrapper'></div>");

            if (!valid) {
                textfield.removeClass("valid"); //just in case
                textfield.addClass("error");
                textfield.parent().append("<div class='input-status input-cross'></div>");
            }
            else {
               // alert('setting textbox invalid');
                textfield.removeClass("error"); //just in case
                textfield.addClass("valid");
                textfield.parent().append("<div class='input-status input-tick'></div>");
            }
        }

        function highlightFieldMessage(textfield, valid, message) {
           // alert('highlightField :' + textfield.attr('id') + ":valid:" + valid + ":MESSAGE:" + message );
            highlightField(textfield, valid);
            alert('here we are afgter sub call');

            if (!valid) {
                textfield.parent().append("<div class='error-popup'>" + message + "<div class='error-popup-arrow'></div></div>");
                textfield.parent().find('.error-popup').css('left', textfield.width() + 58);   
            }
            else {
                textfield.parent().append("<div class='valid-popup'>" + message + "<div class='error-popup-arrow'></div></div>");
                textfield.parent().find('.valid-popup').css('left', textfield.width() + 58);
            }
            alert('ok after adding message etc')
            
        }

Open in new window


Now when I first load and enter the field (i can enter text at this point into the field) and move out of focus from it it works correctly and highlights it as an error field.

When I move it back into focus it remains highlighted as error and displays the message. However at this point the field is not in focus?? i.e. i cannot type into it.

Am i knocking it out of focus in the code or doing something wrong here?

hi,

just to add it seems to be the sub call which unwraps and the rewraps the textbox

http://stackoverflow.com/questions/4350566/jquery-textfield-loses-focus-on-unwrap

unwrap seems to lose the focus of the textbox. Is there anyway I can stop this?

What about :
var f = textfield.is(":focus");
textfield.unwrap();
if(f) textfield.focus();

ok I've tried this but still the same result and it loses focus;

heres my updated code

function highlightField(textfield, valid) {

            var f = textfield.is(":focus");
            unwrap(textfield);

            textfield.wrap("<div class='textbox-wrapper'></div>");
            if (f) textfield.focus();

            if (!valid) {
                textfield.removeClass("valid"); //just in case
                textfield.addClass("error");
                textfield.parent().append("<div class='input-status input-cross'></div>");
            }
            else {
                textfield.removeClass("error"); //just in case
                textfield.addClass("valid");
                textfield.parent().append("<div class='input-status input-tick'></div>");
            }
        }

function unwrap(textfield) {
            if (textfield.parent().is(".textbox-wrapper")) {
                textfield.parent().find(".input-status").remove();

                textfield.parent().find(".error-popup").remove();
                textfield.parent().find(".valid-popup").remove();
                textfield.unwrap();

            }
        }

Try this :
function highlightField(textfield, valid) {

            var f = textfield.is(":focus");
            unwrap(textfield);
            var myfield = textfield;
            textfield.wrap("<div class='textbox-wrapper'></div>");
            if (f)  setTimeout(function() { myfield.focus(); }, 1000); // reduce if it work

            if (!valid) {
                textfield.removeClass("valid"); //just in case
                textfield.addClass("error");
                textfield.parent().append("<div class='input-status input-cross'></div>");
            }
            else {
                textfield.removeClass("error"); //just in case
                textfield.addClass("valid");
                textfield.parent().append("<div class='input-status input-tick'></div>");
            }
        }

function unwrap(textfield) {
            if (textfield.parent().is(".textbox-wrapper")) {
                textfield.parent().find(".input-status").remove();

                textfield.parent().find(".error-popup").remove();
                textfield.parent().find(".valid-popup").remove();
                textfield.unwrap();

            }
        }

perfect thank you.

any ideas why .focus() was not working out of interest? i assume maybe wrap was still doing something?

there's no wizard in the room, to wrap, the element to wrap is removed from the DOM (so loose focus) the wrap element is added to the DOM, the element is added back to the DOM with all its saved attributes (alas not the focus which is not an attribute...)
