sizcache和sizset用jQuery服务的目的是什么

I am using jQuery, and in inspecting the DOM of my page in IE with the Dev Toolbar I see that many elements have sizset and sizcache attributes added to the element. I don't see these in Chrome or Firefox? Also, I see that many elements on the page share the same value for these fields leading me to believe it was a global value, but a few do have different values?

我正在使用jQuery，在IE中使用Dev工具栏检查页面的DOM时，我发现很多元素都添加了sizset和sizcache属性。我在Chrome和火狐都没见过?而且，我发现页面上的许多元素对于这些字段具有相同的值，这使我相信它是一个全局值，但是有一些元素具有不同的值?

<html xmlns="http://www.w3.org/1999/xhtml" sizcache="66" sizset="0">
    <head>...</head>
    <body sizcache="66" sizset="0">
         <div class="ui-datepicker-group ui-datepicker-group-first" sizcache="18" sizset="0">
    </body>
</html>

Does anyone know why IE only shows these, and what purpose they serve?

有谁知道我为什么只展示这些，以及它们的目的是什么?

it's meant for internal use only. The jQuery core file uses it to
calculate nth-child. Here is the source (with my emphasis):

它只供内部使用。jQuery核心文件使用它来计算nth-child。以下是来源(我的重点):

It looks like nodeIndex and sizcache and sizset are all used internally to calculate the nth-child.

看起来nodeIndex、sizcache和sizset都在内部用于计算第n个子元素。
