jQuery live()可与jQuery 1.8.3&以下，但不适用于1.9.1或2.0 [英] jQuery live() works with jQuery 1.8.3 & below but not with 1.9.1 or 2.0

问题描述

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?

推荐答案

.live()方法自jQuery 1.7起已被弃用，并已从1.9中删除.

The .live() method has been deprecated since jQuery 1.7 and has been removed in 1.9.
