在FF模式下工作而不是在IE 7模式下工作

我有一个列表可以切换,在FF中没有问题。我需要这个工作(准备生产)。

似乎(即)仅将JS应用于第一个订单项和第一个家庭。列表中的其余项将被忽略。

任何帮助都会很好。

一段HTML(大列表):

<div class="classificationContainer">

        <ul class="classification" id="orderUL">

        <li id="orderItem" class="ordrheading">
            <div class="order">

                <a href="?nav=search_recherche&amp;lang=en">

  <img src="http://dev.ncr.ec.gc.ca/publications/bba-aob/images/node_closedc.gif" alt="By Classification" id="OrdListImage" />

                    Apodiformes (Swifts and Hummingbirds)
                </a>
            </div>

                    <ul class="classification" id="FamilyList">

                    <li id="familiy">
                        <div class="family">
                            <a href="?nav=search_recherche&amp;lang=en">


  <img src="http://dev.ncr.ec.gc.ca/publications/bba-aob/images/node_closedc.gif" alt="Family" id="FamListImage" />

                                Apodidae (Swifts)
                            </a>
                        </div>

                                <ul class="classification" id="SpiecesList">

                                <li>
                                    <img src="http://dev.ncr.ec.gc.ca/publications/bba-aob/images/node_leafc.gif" alt="Species" />
                                    <a href="?lang=en&amp;nav=bird_oiseaux&amp;aou=423"> Chimney Swift (Chaetura pelagica) </a>

                                </li>

                                </ul>

                    </li>

                    <li id="familiy">
                        <div class="family">
                            <a href="?nav=search_recherche&amp;lang=en">

  <img src="http://dev.ncr.ec.gc.ca/publications/bba-aob/images/node_closedc.gif" alt="Family" id="FamListImage" />

                                Trochilidae (Hummingbirds)
                            </a>

                        </div>

                                <ul class="classification" id="SpiecesList">

                                    <a href="?lang=en&amp;nav=bird_oiseaux&amp;aou=428"> Ruby throated Hummingbird (Archilochus colubris) </a>

                                <li>
                                    <img src="http://dev.ncr.ec.gc.ca/publications/bba-aob/images/node_leafc.gif" alt="Species" />

                    </li>

                    </ul>

        </li></ul></div>

我有以下jquery函数:

<script type="text/javascript">
    $(document).ready(function () {
    // toggle action for the order to familiy
    $("li#orderItem").click(function (event) {
        // toggle the image
        var src = ($("#OrdListImage", this).attr("src") == "/images/node_closedc.gif")
                ? "/images/node_openc.gif"
                : "/images/node_closedc.gif";
        $("img#OrdListImage", this).attr("src", src);

        //toggle the ul
        $('ul#FamilyList', this).toggle($('ul#FamilyList', this).css('display') == 'none');

        // stop all link actions
        return false;
    });

    //toggle action from familiy to speices
    $("li#familiy").click(function () {
        // toggle the image
        var src = ($("#FamListImage", this).attr("src") == "/images/node_closedc.gif")
                ? "/images/node_openc.gif"
                : "/images/node_closedc.gif";
        $("img#FamListImage", this).attr("src", src);            
        //toggle the ul
        $('ul#SpiecesList', this).toggle($('ul#SpiecesList', this).css('display') == 'none');

        // stop all link actions
        return false;
    });


});
