jQuery live()可与jQuery 1.8.3&以下，但不适用于1.9.1或2.0

我一直在使用 http://ajax .googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js 已有一段时间了，一切都很好，但是1.8.3已经很老了，所以我决定移至最新的jQuery.突然有些事情停止了工作: Quicksand插件和我自己的jQuery代码的一部分(在每个滑块).

I've been using http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js for a while now and everything has been fine, but 1.8.3 got quite old so I've decided to move to the latest jQuery. And suddenly a few things stopped working: Quicksand plugin and part of my own jQuery code (that shows additional data under every slide of a slider).

您能帮我弄清楚出什么问题吗?还是不值得转移到1.8.3以上的jQuery版本?检查Jsfiddle.

Can you help me figuring out what's wrong? Or maybe it's not worth moving to jQuery versions above 1.8.3? Check the Jsfiddle.

HTML:

<a href="#" class="show" data-show="first">SHOW</a>
<a href="#" class="show" data-show="second">SHOW</a>

<div id="first">First paragraph.</div>
<div id="second">Second paragraph</div>

JS:

jQuery(".show").live("click", function (e) {
    var slide = '#' + jQuery(this).data('show');
    jQuery(slide).slideToggle();
    e.preventDefault();
});

CSS:

div { display: none; }

尝试将jQuery更改为1.9.1或2.0，然后单击运行".脚本停止工作.为什么?

Try changing jQuery to 1.9.1 or 2.0 and hit Run. Script stops working. Why?
