html - 如何防止 <div> 在 Firefox 中 float 在其他 div 之上？

标签 html firefox css

在我正在做的元素中，我有多个分区，一个一个地放在另一个下面，我根据导航栏的选择一个接一个地加载它们。如果我在 <div> 中没有任何花哨的元素，现在就可以正常工作了.但是当我将一个表单添加到一个 div 时，它开始漂浮在它上面的 div 上。当我选择表单中的任何元素时会发生这种情况。此外，我似乎无法选择 dropDown 中的任何元素。 <form> 中的列表.

这是分区列表的示例代码

 <div class="container">
            <div class="st-container">

                    <input type="radio" name="radio-set" checked="checked" id="st-control-1"/>

                    <a href="#st-panel-2">Happiness</a>
                    <input type="radio" name="radio-set" id="st-control-3"/>

此问题仅发生在 Firefox 中(我使用的是 Firefox 16.0)。 这是一个JSFiddle的问题。单击导航栏中的“幸福”选项以转到有问题的部分。 有人可以帮我解决这个问题吗？

最佳答案

似乎 css 魔术在“制表符”方面混淆了 Firefox。这是一个非常有趣的问题，因为 Firefox 似乎试图定位标签并自动对齐视口(viewport)以使其位于顶部，尽管它已经是......CSS 明智的，我无能为力，即使 overflow:hidden，你仍然可以使用鼠标中键滚动正文，从而导致 Firefox 中存在的对齐问题。使用 google chrome，多次按“Serendipity”选项卡上的选项卡将导致视口(viewport)直接滚动到输入选项卡。参见 Avoid unwanted scrolling triggered by keyboard navigation in IE?

但是，使用 javascript，如果您愿意牺牲站点的“无 javascript”方面，这一切都可以轻松避免。

var tabs = document.getElementById("registration-form").elements;
for (var i = 0; i < tabs.length; i++) {
    tabs[i].setAttribute("tabindex", i + 1);
    tabs[i].addEventListener('keydown', function(e) {
        var e = window.event || e;
        var keyCode = e.keyCode || e.which;

        if (keyCode == 9) {
            e.preventDefault();

            var x = window.scrollX,
                y = window.scrollY;

            var elementToFocus = document.getElementById("registration-form").elements[this.getAttribute("tabindex")];
            if (typeof elementToFocus == "undefined") {
                elementToFocus = document.getElementById("registration-form").elements[0];
            }
            elementToFocus.focus();
            window.scrollTo(x, y);

        }
    });
}
window.addEventListener("scroll", function(e) {
    var e = window.event || e;
    e.preventDefault();
    window.scrollTo(0, 0);
});​
