使用jQuery来选择具有样式“可见性：可见”的项目。或“可见性：隐藏” NOT“display：none” [英] Using jQuery to select items that have style "visibility:visible" or "visibility:hidden" NOT "display: none"
问题描述
如何使用jQuery仅选择可见元素？
How do you select only visible elements using jQuery?
jQuery选择器：visible和：hidden仅尊重display：none as really hidden ？不可见性：隐藏或可见性：可见。
jQuery selectors :visible and :hidden only respects display:none as really hidden? NOT visibility:hidden or visibility:visible.
我理解他们不是技术上隐藏的，因为他们仍然占用他们的空间。我只想知道他们的状态，所以我可以选中可见的复选框。
I understand they are not technically hidden because they still take their space. I just want to know their state so I can check checkboxes that are visible.

推荐答案
您可以使用 css 函数来获取元素的样式，过滤器函数从一组元素中选择它们：
You can use the css function to get the style of the element, and the filter function to select them from a collection of elements:
var visible = $('input[type=checkbox]').filter(function() {
return !($(this).css('visibility') == 'hidden' || $(this).css('display') == 'none');
});
