I am creating a address validator web application using google maps.my UI:

]

Now which I want is after pressing ok button address should be shown into your address look like field like this 701 1st, Sunnywale, CA 94089 now my ok button click event is

FullAddress.Text = AddressLine1.Text + ',' + ' ' + City.Text + ',' + ' ' + State.Text+ ' ' +Zip.Text;

but when i add javascript to call google maps with my program its not working its throgh a error like as sample pic. Please help me guys. ok button :

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="OK" 
            Width="62px" style="margin-left: 0px" />

Validate & Locate Me Button code:

<asp:Button ID="Submit" runat="server" style="margin-left: 97px" Text="Validate &amp; Locate Me" Width="137px" />

Now jQuery and geocode part:

<script type="text/javascript">
    // The following code show execute only after the page is fully loaded
    $(document).ready(function () {
        if ($('#MyForm').exists()) {

            // Enable jQuery Validation for the form
            $("#MyForm").validate({ onkeyup: false });

            // Add validation rules to the FullAddress field
            $("#FullAddress").rules("add", {
                fulladdress: true,
                required: true,
                messages: {
                    fulladdress: "Google cannot locate this address."
                }
            });

            // This function will be executed when the form is submitted
            function FormSubmit() {
                $.submitForm = true;
                if (!$('#MyForm').valid()) {
                    return false;
                } else {
                    if ($("#FullAddress").data("IsChecking") == true) {
                        $("#FullAddress").data("SubmitForm", true);
                        return false;
                    }

                    alert('Form Valid!  Submit!');
                    // return true;   // Uncomment to submit the form.
                    return false;     // Supress the form submission for test purpose.

                }
            }

            // Attach the FormSubmit function to the Submit button
            if ($('#Submit').exists()) {
                $("#Submit").click(FormSubmit);
            }

            // Execute the ForumSubmit function when the form is submitted
            $('#MyForm').submit(FormSubmit);
        }
    });

    // Create a jQuery exists method
    jQuery.fn.exists = function () { return jQuery(this).length > 0; }

    // Position the Google Map
    function Map(elementId, geolocation) {
        var myOptions = {
            zoom: 13,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var map = new google.maps.Map(document.getElementById(elementId), myOptions);
        map.setCenter(geolocation);
    }

    // FullAddress jQuery Validator
    function FullAddressValidator(value, element, paras) {

        // Convert the value variable into something a bit more descriptive
        var CurrentAddress = value;

        // If the address is blank, then this is for the required validator to deal with.
        if (value.length == 0) {
            return true;
        }

        // If we've already validated this address, then just return the previous result
        if ($(element).data("LastAddressValidated") == CurrentAddress) {
            return $(element).data("IsValid");
        }

        // We have a new address to validate, set the IsChecking flag to true and set the LastAddressValidated to the CurrentAddress
        $(element).data("IsChecking", true);
        $(element).data("LastAddressValidated", CurrentAddress);

        // Google Maps doesn't like line-breaks, remove them
        CurrentAddress = CurrentAddress.replace(/\n/g, "");

        // Create a new Google geocoder
        var geocoder = new google.maps.Geocoder();
        geocoder.geocode({ 'address': CurrentAddress }, function (results, status) {

            // The code below only gets run after a successful Google service call has completed.
            // Because this is an asynchronous call, the validator has already returned a 'true' result
            // to supress an error message and then cancelled the form submission.  The code below
            // needs to fetch the true validation from the Google service and then re-execute the
            // jQuery form validator to display the error message.  Futhermore, if the form was
            // being submitted, the code below needs to resume that submit.

            // Google reported a valid geocoded address
            if (status == google.maps.GeocoderStatus.OK) {

                // Get the formatted Google result
                var address = results[0].formatted_address;

                // Count the commas in the fomatted address.
                // This doesn't look great, but it helps us understand how specific the geocoded address
                // is.  For example, "CA" will geocde to "California, USA".
                numCommas = address.match(/,/g).length;

                // A full street address will have at least 3 commas.  Alternate techniques involve
                // fetching the address_components returned by Google Maps.  That code looks even more ugly.
                if (numCommas >= 3) {

                    // Replace the first comma found with a line-break
                    address = address.replace(/, /, "\n");

                    // Remove USA from the address (remove this, if this is important to you)
                    address = address.replace(/, USA$/, "");

                    // Check for the map_canvas, if it exists then position the Google Map
                    if ($("#map_canvas").exists()) {
                        $("#map_canvas").show();

                    }

                    // Set the textarea value to the geocoded address
                    $(element).val(address);

                    // Google Maps was able to geocode the address, but it wasn't specific
                    // enough (not enough commas) to be a valid street address.
                    $(element).data("IsValid", false);
                }

                // Otherwise the address is invalid
            } else {

            // Get the parent form element for this address field
            var form = $(element).parents('form:first');

            // This code is being run after the validation for this field,
            // if the form was being submitted before this validtor was
            // called then we need to re-submit the form.
            if ($(element).data("SubmitForm") == true) {
                form.submit();
            } else {

        });

        // The FullAddress validator always returns 'true' when initially called.
        // The true result will be return later by the geocode function (above)

Please help after pressing ok button full address isnt shown into Your address look like field.Instead of that its through a message: This Field is required. If further more details needed please mention it

Answer 1

Simply use 2 FORMS to keep your controls. First one will have the address fields and the OK button.
Second will have the rest. Change your code accordingly. It should work. Otherwise you need to assign classes and group the controls into 2 sets.
What I mean by 2 sets is that "OK" button should validate the fields above it. And "Validate and Locate Me" button should validate only "Your address look like" text box. With jquery you can think of many ways how to group controls and validate them.

If this is not solving please provide the HTML as well or use http://jsfiddle.net/

-- edit --
The problem you have is when you press OK, it validates a field beneath it. Now what I feel is you have used a Required Field Validator without any grouping. Please specify a ValidationGroup property to separate the validation criteria of "OK" button and "Validate and Locate Me" button. If you don't know how to use ValidationGroup let me know.
