IE7：李的行为很糟糕

IE7给了我和我的网站一点悲伤。尽管我想在一条黑暗的小巷里与微软见面，并且一劳永逸地对它进行排序，但我希望你们中的一个可以提供帮助。

IE7以两种方式损害了我的li代码，第一种是不尊重width:auto;属性，而不是扩展到最宽li的宽度，每个li缩小到自己的副本和填充的大小。

从这里可以看出：

curse you IE7

接下来，IE7不尊重我的jQuery。我有一个函数，当您将鼠标悬停在每个父ul上时，它会向下滑动li。但IE7出于某种原因（我认为它与display: none有关）在动画期间低估了ul的宽度，并在完成后弹出正确的宽度。

从这里可以看出：

Shuttupa your face, you gotsa no respect

所以这是我的下拉列表的标记：

<div class="container_16">
    <div class="grid_16">
        <div id="breadcrumbs">
            <a href="http://rcnhca.org.uk/sites/first_steps" id="home"></a>
            <ul id="parent" class="grid_15 omega">

和要开机的CSS：

#breadcrumbs {
    position: relative;
    z-index: 4;
    height: 39px;
    padding-bottom: 3px;
    background: #ffffff;

    -moz-border-radius-bottomright: 5px;
    border-bottom-left-radius: 5px;
    border-bottom-right-radius: 5px;
}

}

.js #breadcrumbs ul#parent li ul {
    display:none;
}

.no-js #breadcrumbs ul#parent li ul {
    left: -999em;
}

#breadcrumbs ul#parent li ul li {
    float: none;
    display: block;
    position: relative;

    background-color: #738793;
    border-radius: 5px; 
    -moz-border-radius: 5px; 
    -webkit-border-radius: 5px;
    line-height: 26px;
    white-space: nowrap;
    zoom: 1;
    width: auto;
}

#breadcrumbs ul#parent li ul li a{
    display: block;
    color: #ffffff;
    text-decoration: none;
    text-shadow: none;
    font-weight: 100;
}

#breadcrumbs ul#parent li ul li.active, #breadcrumbs ul#parent li ul li:hover{
    background-color: #3393b5;
}

#breadcrumbs ul#parent li ul li.active, .no-js #breadcrumbs ul#parent li ul li:hover{
    background-position: 0px 50%;
    text-indent: 10px;
}

.no-js #breadcrumbs ul#parent li:hover ul, .no-js #breadcrumbs ul#parent li:focus ul {
    left: -5px;
}

和动画它的jQuery：

$(document).ready(function(){

    // Fix background-position < IE8
    if ($('html').hasClass('oldie')) {
        $("ul.child li:not(.active)").each(function() {
            $(this).css('backgroundPosition', '-25px 50%');
        });
        $("#breadcrumbs ul")
    }

    //Animate dropdown menu
    $("#breadcrumbs>ul:not(.child)>li").each(function() {
        crumbWidth = $(this).width();
        if($(this).width() > $(this).children('ul.child').width()) {
            $(this).children('ul.child').width(crumbWidth + 43);
        }
    });
    $("#breadcrumbs>ul:not(.child)>li").hover(
      function () {
        var raquo = "&raquo;";
        $(this).children('ul.child').hoverFlow('mouseenter', {'height': 'show'},250).children('li:not(.active)').hover(
            function() {
                $(this).hoverFlow('mouseenter', {textIndent: 10, backgroundPosition: '-0px 50%'}, 250);
            },
            function () {
                $(this).hoverFlow('mouseleave', {textIndent: 0, backgroundPosition: '-25px 50%'}, 250);
            }
        );
      }, 
      function () {
        $(this).children('ul.child').hoverFlow('mouseleave', {'height': 'hide'}, 250).children('li').unbind();
      }
    );
});

width:100%上的

#breadcrumbs ul#parent li ul似乎解决了这两个问题。 http://jsfiddle.net/F6LBV/4

到目前为止，已在IE7和Chrome中测试过。
