我正在处理 IE 11 在 Windows 8 和 Windows 8.1 上的奇怪行为。我正在固定定位元素内的元素位置。而且它变得很奇怪。当我用开发工具检查它时它在正确的位置,但在视觉上它完全在不同的地方。我发现如果我暂时禁用父元素的位置规则然后再次启用它,子元素之后会正确呈现。 Win 7 上的 IE 11 没有这个问题。

}

JS:

$.fn.ready(function () {
OnShown();
$('#photo-modal').scroll(OnScroll);
$(window).resize(OnScroll);
});

function OnShown() {
var $modal = $('#photo-modal');
$modal.find('.modal-footer').css('padding-bottom', $modal.find('form').height() + 20);
OnScroll();
}

function OnScroll() {
var $modal = $('#photo-modal');
var $dialog = $modal.find('.modal-dialog');
var $footer = $modal.find('.modal-footer');
var $form = $modal.find('form');
$form.width($dialog.width() - 42)
.css({
'left': $dialog.offset().left
});

var wHeight = $(window).height();
var elTop = $modal.offset().top;
var footerTop = $footer.offset().top;

var dialogMB = parseInt($dialog.css('margin-bottom'));
if ($modal.scrollTop() + wHeight >= $dialog.outerHeight(true) - dialogMB) {
$form.css('margin-bottom', dialogMB);
} else {
$form.css('margin-bottom', 0);
}

if (footerTop - elTop + $form.outerHeight(true) < wHeight) {
$form.css('visibility', 'visible');
} else {
$form.css('visibility', 'hidden');
}
}

如果您很幸运没有看到问题,请尝试调整结果 Pane 的大小(在某些维度上有时它会正确呈现)。

最佳答案

如果您有背景颜色/图像,并且某个元素固定在其上,则必须移除该元素背面 以避免重绘问题。添加这些属性并删除可见性。

CSS:

#photo-modal form {
...
display: none;
backface-visibility: hidden;
}

JS:

if (footerTop - elTop + $form.outerHeight(true) < wHeight)
$form.css('display', 'block');
else
$form.css('display', 'none');

为什么显示而不是可见性,因为可见性只是隐藏上下文,这不会改变它与其他元素的交互。
