实现一个js的分页并在弹出框中显示
1.分页插件使用：bootstarp-paginator.js,需要先引入bootstarp.js和jquery.js等；
!function($){"use strict";var BootstrapPaginator=function(element,options){this.init(element,options)},old=null;BootstrapPaginator.prototype={init:function(element,options){this.$element=$(element);var version=options&&options.bootstrapMajorVersion?options.bootstrapMajorVersion:$.fn.bootstrapPaginator.defaults.bootstrapMajorVersion,id=this.$element.attr("id");if(2===version&&!this.$element.is("div"))throw"in Bootstrap version 2 the pagination must be a div element. Or if you are using Bootstrap pagination 3. Please specify it in bootstrapMajorVersion in the option";if(version>2&&!this.$element.is("ul"))throw"in Bootstrap version 3 the pagination root item must be an ul element.";this.currentPage=1,this.lastPage=1,this.setOptions(options),this.initialized=!0},setOptions:function(options){this.options=$.extend({},this.options||$.fn.bootstrapPaginator.defaults,options),this.totalPages=parseInt(this.options.totalPages,10),this.numberOfPages=parseInt(this.options.numberOfPages,10),options&&"undefined"!=typeof

2、初始化配置：
pagination : { currentPage : 1, start : 0, number : 20, totalCount : 0, totalPages : 0, numberOfPages : 0, bootstrapMajorVersion:3 }
其中 bootstrapMajorVersion的值需要根据实际情况配置；
3、列表展示实现：
var clips = mobject.list; var assets = ''; for(var i=0;i<clips.length;i++){ var clip = clips[i]; var icon = ''; var duration = ''; assets+='<li"><div class="row"> <input type="checkbox" style="float:left"> <span class="col-md-11 name">'+icon+'</span> <span class="col-md-3 caption">大小：'+clip.size.toStorageString()+'</span> <span class="col-md-2 caption">时长：'+duration+' </span> <span class="col-md-5 caption">创建日期：'+clip.createdTime.formatDate("yyyy-MM-dd hh:mm:ss")+'</span> </div></li>'; } $('.clip-items>ul').html(assets); var page = '<ul class="pagination"></ul> <div class="footer-center">共<span>'+pagination.numberOfPages+'</span> 页/共 <span>'+pagination.totalCount+'</span> 条</div> <div class="footer-right">每页显示 <select id="pageSize" onchange="sizeChange()"> <option value="10">10</option> <option value="20">20</option> <option value="30">30</option> <option value="40">40</option> <option value="50">50</option> </select> </div>'; $('.page-footer').html(page); $('#pageSize').val(pagination.number); //分页需要totalPages属性 pagination.totalPages =pagination.numberOfPages; pagination.numberOfPages = 5; pagination.onPageClicked = function(event, originalEvent, type, page){ pagination.currentPage = page; refresh(); } $('.pagination').bootstrapPaginator(pagination); }
sizeChange:function(){ pagination.number = $('#pageSize').val(); refresh(); }
