Question

我有链接和一个div。我想在用户点击链接时在链接下显示div。我希望通过代码将div放在链接下方，这意味着div的顶部＆amp; left将根据top＆amp; amp;左侧链接位置。需要帮助。

<a id="link">About</a>

<div id="submenu">
     <a href="#">About the company</a><br />
     <a href="#">Careers</a>
</div>

Answer 1

要在您的链接下显示<div>，您可以执行以下操作：

$('#link').click(function() {
    $('#submenu').css({
        left: $(this).offset().left + 'px',
        top: ($(this).offset().top + $(this).height()) + 'px'
    }).show();
});

在你的CSS中：

#submenu {
    position: absolute;
}

此代码可以帮助您

$("#link").click(function () {
       $('#submenu').insertAfter($('#link'));
        $('#submenu').css({left: $(this).offset().left + 'px',
                           top: ($(this).offset().top + $(this).height()) + 'px',
                           position: "absolute"
        }).show();
    });
