如何选择区间之间的元素
我有 html，想从第 10 个位置选择间隔 5 个元素。如何做到这一点？
我的 html：
<div class="chaire">
<img alt="" src="2.gif">
</div>
<div class="chaire">
<img alt="" src="2.gif">
</div>
<div class="chaire">
<img alt="" src="2.gif">
</div>
<div class="chaire">
<img alt="" src="2.gif">
</div>
...
<div class="chaire">
<img alt="" src="2.gif">
</div>
我尝试使用 jquery：
$(".chaire:gt(10):lt(15)");
但它选择了我的 div 和 img 标签。但我需要 div 标签。

您的代码可以很好地完成工作，并且仅选择元素。看一下这个小提琴示例，它找到了 5 个元素第 10 个之后 (:gt(9):lt(15))。The selector you have will only select elements with that class name, in the case of your example HTML, it's just the
<div>elements. No<img>elements will be selected. As rcravens had already pointed out, the two selectors modify the result separately, so you need to use:lt()first -:lt(15):gt(9).更新示例位于：http://jsfiddle.net/teQkf/3/。示例代码的下一部分在结果中查找
![]()
您最好使用
slice，这只是对结果因此不那么混乱，更不用说更快了：（示例）
Your code does the job just fine, and selects only<div>elements. Take a look at this example fiddle, which finds 5<div>elements after the 10th (:gt(9):lt(15)).The selector you have will only select elements with that class name, in the case of your example HTML, it's just the
<div>elements. No<img>elements will be selected. As rcravens had already pointed out, the two selectors modify the result separately, so you need to use:lt()first -:lt(15):gt(9).Updated example at: http://jsfiddle.net/teQkf/3/. The next part of the example code finds the
<img>elements within the result and changes their src to something else.You're better off using
slice, which is only a single operation on the result and therefore less confusing, not to mention faster:(example)
试试这个：
这是一个可以玩的jFiddle。

它看起来像是链接“gt”和“ lt' 选择器意味着 'lt' 应用于 'gt' 之后剩余的内容。

try this:
Here is a jFiddle to play around with.

It looks like chaining the 'gt' and 'lt' selectors means 'lt' is applied to what remains after the 'gt'.
