Jquery a类：悬停用于文本装饰，但不用于颜色

我有以下HTML代码：

    <h1>No Real Purpose</h1>

    <!--Navigation menu-->
    <div id = "navBar">
        <ul>
            <li class = "navLink">
                <a href = "page 1.html">Page 1</a>
            </li>
            <li class = "navLink">
                <a href = "page 2.html">Page 2</a>
            </li>
            <li class = "navLink">
                <a href = "page 3.html">Page 3</a>
            </li>
            <li class = "navLink">
                <a href = "page 4.html">Page 4</a>
            </li>
            <li class = "navLink">
                <a href = "page 5.html">Page 5</a>
            </li>
            <li class = "navLink">
                <a href = "page 6.html">Page 6</a>
            </li>
            <li class = "navLink">
                <a href = "page 7.html">Page 7</a>
            </li>
            <li class = "navLink">
                <a href = "page 8.html">Page 8</a>
            </li>
            <li class = "navLink">
                <a href = "page 9.html">Page 9</a>
            </li>
            <li class = "navLink">
                <a href = "page 10.html">Page 10</a>
            </li>
        </ul>
    </div>
    <br />
    <br />
    <!--Main content area-->
    <div id = "main">

            <!--collapsible <div>'s-->
        <div class = "collapse">

            </p>
        </div>
    </div>

    <!--The colorPicker I'm working on-->
    <table id = "colorPicker">
        <tr>
            <th colspan = "6">Color Picker</th>
        </tr>
        <tr>
            <td id = "blackOpt"></td> <td id = "redOpt"></td> <td id = "orangeOpt"></td> <td id = "greenOpt"></td> <td id = "indigoOpt"></td> <td id = "lightGrayOpt"></td>
        </tr>
        <tr>
            <td id = "whiteOpt"></td> <td id = "brownOpt"></td> <td id="yellowOpt"></td> <td id = "blueOpt"></td> <td id = "violetOpt"
></td> <td id = "darkGrayOpt"></td>
        </tr>
    </table>
</body>
</html>

以及以下jQuery代码：

$(document).ready(function()
{
    //Changes the #navBar colors on mouseenter
    $('.navLink').mouseenter(function()
    {
        $(this).css('background-color', '#004400');
        $(this).closest('a:link').css('color', '#F8F8F8');
    });

    //Reverts the #navBar colors on mouseleave
    $('.navLink').mouseleave(function()
    {
        $(this).css("background-color","rgba(240,240,240,0.5)");
    });

    //Toggles the <p> closest to a +/- <span>
    $('.cause').click(function()
    {
        $(this).closest('.collapse').find('.effect').slideToggle('slow');
    });

    //Runs the colorPicker (work in progress)
    $('td').parent('#colorPicker').click(function()
    {
        var priColor = $(this).css('backgroundColor');
        $('body').css(priColor);
    });
});

$（文档）.ready（函数（）
{
//更改鼠标指针上的#导航栏颜色
$（'.navLink'）.mouseenter（函数（）
{
$（this.css（'background-color'，'#004400'）；
$（this）.closest（'a:link'）.css（'color'，'#f8'）；
});
//还原mouseleave上的#导航栏颜色
$（'.navLink'）.mouseleave（函数（）
{
css（“背景色”、“rgba（2400,0.5）”）；
});
//切换距离a+/-最近的
$（'.cause'）。单击（函数（）
{
$（this）.最近（'.collapse'）。查找（'.effect'）。滑动切换（'slow'）；
});
//运行颜色选择器（正在工作）
$（'td'）。父项（'colorPicker'）。单击（函数（）
{
var priColor=$（this.css（'backgroundColor'）；
$（'body'）.css（priColor）；
});
});

我正在尝试建立一个带有颜色选择器的实践站点，但这不是我目前的主要关注点。尽管我为

.navLink a:link

和

设置了值，但谷歌浏览器忽略了这些代码。我知道这很好，因为链接是黑色的（不是蓝色的），下划线消失了（多亏了
文本装饰）
，而且它在Firefox和IE9中工作得很好。问题是铬

：hover必须位于CSS定义中的：link和：visted（如果存在）之后，才能生效

尝试将
：hover
规则放在
#navBar a:visted
规则之后
