如何使用jQuery缩短表格分页

我已经按照您的要求显示了省略号。但是，目前它只在您单击任何一个分页链接时起作用。一旦你知道了这个想法，你就很容易在点击之前让省略号出现。我把这一步留给你，直接向你介绍我所做的一切。

1. 在以下代码中搜索注释// Added class and id in li start以查看第一个更改。评论中清楚地提到了它的作用。它添加了id和类以供将来参考。
2. 在以下代码中搜索注释// Added few lines from here start以查看一些其他代码。首先，我们隐藏除前一个和下一个链接之外的所有链接，如果存在，也删除省略号，其次，我们显示三个分页链接，第三，我们检查是否只显示两个链接而不是三个链接，并确保其中三个被显示，最后，如果页面超过三个，我们显示省略号。

更新:

我已经更新了代码与bootstrap css工作，并使它开始与省略号为您。希望您满意。

$.fn.pageMe = function(opts) {
  var $this = this,
    defaults = {
      perPage: 7,
      showPrevNext: false,
      hidePageNumbers: false
    },
    settings = $.extend(defaults, opts);
  var listElement = $this;
  var perPage = settings.perPage;
  var children = listElement.children();

  if (typeof settings.childSelector != "undefined") {
    children = listElement.find(settings.childSelector);
  }
  if (typeof settings.pagerSelector != "undefined") {
    pager = $(settings.pagerSelector);
  }
  var numItems = children.size();
  var numPages = Math.ceil(numItems / perPage);
  pager.data("curr", 0);

    $('<li><a href="#" class="prev_link">«</a></li>').appendTo(pager);
  }

    }
    currpg.addClass("active").siblings().removeClass("active");
    // Added few lines till here end
    children.css('display', 'none').slice(startAt, endOn).show();
    if (page >= 1) {
      pager.find('.prev_link').show();

我认为你的来源是工作!但是也许，你忘记设置插件了:
