Question

我的代码可以在这里找到：http://macrorevolution.com/calculators/tdee/

当我将鼠标放在最后<option></option>上时，它不会突出显示而不是其他选项。我尝试添加更多选项，每次都是最后一个不突出显示的选项。我该如何解决这个问题？

<?php
$answer = "";
$agev = "";
$feetv = "";
$inchesv = "";
$weightv = "";
$sex = "";
$activelevel = "";
if(isset($_POST['agev']) && isset($_POST['feetv']) && isset($_POST['inchesv']) && isset($_POST['weightv']) && isset($_POST['sex'])) {
    //&& isset($_POST['activelevel'])
    $agev = $_POST['agev'];
    $feetv = $_POST['feetv'];
    $inchesv = $_POST['inchesv'];
    $weightv = $_POST['weightv'];
    $sex = $_POST['sex'];
    $activelevel = $_POST['activelevel'];
    $totalheightv = $inchesv + ($feetv*12);
    $heightcm = $totalheightv*2.54;
    $weightkg = $weightv/2.2;

    if($activelevel=='1v') $activelevel=1.2;
    else if($activelevel=='2v') $activelevel=1.375;
    else if($activelevel=='3v') $activelevel=1.55;
    else if($activelevel=='4v') $activelevel=1.725;
    else if($activelevel=='5v') $activelevel=1.9;
    else echo "error";
    //echo $activelevel;

    if($sex=='male') $answer = $activelevel * (66.47 + (13.75*$weightkg) + (5*$heightcm) - (6.75*$agev));
    if($sex=='female') $answer = $activelevel * (665.09 + (9.56*$weightkg) + (1.84*$heightcm) - (4.67*$agev));


}
?>

更新 This Chrome bug ticket，类似于下面列出的错误提示，但此故障单特定于Chrome 32.0.1700.76

<小时/> 我假设您使用的是Chrome？

我和我的同事昨天在我们下载的每一页都遇到了这个问题。

恰好有chrome bug描述完全相同的问题。此bug ticket在故障单的标题中指明了不同版本的chrome，但如果您阅读了他们注意到的评论，则它也会影响其他版本的Chrome。我读过的论坛帖子碰巧与我的浏览器/操作系统（我的64位）相同

Chrome版本：32.0.1700.76 m 操作系统：Windows 7

要验证您在Chrome浏览器中尝试以下步骤（bug ticket中的步骤）

哪些步骤会重现这个问题？


启动Chrome并打开“chrome：// settings”

点击任何下拉箭头以打开下拉列表

鼠标悬停在所有下拉项目上并观察

我认为问题不在于您的代码，而在于Chrome。所以目前你无能为力。

所有的一切都说，即使它没有突出显示，它仍然应该是可点击的。

HTML选择框不会突出显示最后一个选项
