Question

Script:

$(document).ready(function() {
    //Change these values to style your modal popup
    var align = 'center';                               //Valid values; left, right, center
    var top = 100;                                          //Use an integer (in pixels)
    var width = 500;                                        //Use an integer (in pixels)
    var padding = 10;                                   //Use an integer (in pixels)
    var backgroundColor = '#FFFFFF';                        //Use any hex code
    var source = 'AttractionDetails.aspx?AttractionID=  **HOW_DO_I_GET_THE_VALUE_FROM_HIDDEN_FIELD** ';                                 //Refer to any page on your server, external pages are not valid e.g. http://www.google.co.uk
    var borderColor = '#333333';                            //Use any hex code
    var borderWeight = 4;                                   //Use an integer (in pixels)
    var borderRadius = 5;                                   //Use an integer (in pixels)
    var fadeOutTime = 300;                                  //Use any integer, 0 = no fade
    var disableColor = '#666666';                           //Use any hex code
    var disableOpacity = 40;                                //Valid range 0-100
    var loadingImage = 'lib/release-0.0.1/loading.gif';     //Use relative path from this page

    //This method initialises the modal popup
    $(".modal").click(function() {
        modalPopup(align, top, width, padding, disableColor, disableOpacity, backgroundColor, borderColor, borderWeight, borderRadius, fadeOutTime, source, loadingImage);
    });

    //This method hides the popup when the escape key is pressed
    $(document).keyup(function(e) {
        if (e.keyCode == 27) {
            closePopup(fadeOutTime);
        }
    });

});

LISTVIEW:

<ItemTemplate>
                        <td id="Td6" runat="server" style="background-color: #FFFFFF; color: #000000; width: 120px;">
                            <asp:Label ID="AttractionNameLabel" runat="server" Text='<%# Eval("AttractionName") %>' />
                            <br />
                            <a class="modal" href="javascript:void(0);"> Modal Pop Up </a>
                            <asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("AttractionID") %>' />

                        </td>
                    </ItemTemplate>

All i want is to get the HiddenField value of the item being clicked [on clicking on the hyperlink “Modal Pop Up” ] using javascript.

Thanks in advance.

You can do it without using hidden field. Add data attribute and set it with AttractionID. Using hidden field for holding and passing value is not required by this method.

<a class="modal" href="javascript:void(0);" data-AttractionID='<%# Eval("AttractionID") %>'> Modal Pop Up </a> 

Get the attractionID assigned to anchor tag

 $(".modal").click(function() {
        valueofAttractionID = $(this).data('AttractionID');
        modalPopup(align, top, width, padding, disableColor, disableOpacity, backgroundColor, borderColor, borderWeight, borderRadius, fadeOutTime, source, loadingImage);
    });
