如何在同一页面上创建这个jquery插件的多个实例？
问题描述：
请问我在同一页面上制作这个jQuery插件的多个实例。问题是第一位的工作正常，但别人不一样，这里是我的代码：如何在同一页面上创建这个jquery插件的多个实例？

请，如果任何人能帮助我
谢谢！
答
不要选择元素
$('.easyPaginateNav a.next')
但使用所述插件元件（S）：
plugin.el.find('easyPaginateNav a.next'`)
你做到了很好的在这个例子行：
plugin.nav.find('.current').removeClass('current');
这样您将始终选择当前插件实例中的元素。
编辑：
改变了很多东西，甚至不知道是什么原因导致的主要问题（这是plugin.settings.objElements是不正确的）。请检查下面的代码：
$.fn.easyPaginate = function(options) {
var defaults = {
paginateElement: 'li',
hashPage: 'page',
elementsPerPage: 10,
effect: 'default',

firstButtonText: '<<',
lastButton: true,
lastButtonText: '>>',
prevButton: true,
prevButtonText: '<',
nextButton: true,
nextButtonText: '>'
