分享一个前端拿到数据后,自己生成分页的案例,案例如图显示,点击搜索后查询数据,显示数据列表,前端根据数据显示正确的分页
附上代码:代码附上,简单粗暴,自己用过的,兼容性好,没有封装,可以很好的分页原理,希望可以帮助到大家
html排版如下:
<!--搜索列表--><div class="search"> <div class="container"> <div class="searchList"> <table id="searchList"> <!--<tr> <td> <a href=""> <p class="title">正标题</p> <p class="className"><span>所属分类</span><em class="date">2019-01-01</em></p> <p class="detail">搜索详细信息展示,要考虑没有的情况下,不显示只显示标题</p> </a> </td> </tr>--> </table> <div class="pageRow"> <div id="pageination"></div> </div> </div> </div></div>
js代码如下:每一步操作都有注释
//鼠标点击的时候搜索 function searchAction() { var serchId=$(‘#serchId‘).val(); $.ajax({ type:"post", url:"Web/search", data:{"search":serchId}, success:function (data) { if(data.total!=0){ $(‘#searchList‘).empty(); $.each(data.list,function (i,obj) { var lielem=‘<tr>\n‘ + ‘ <td>\n‘ + ‘ <a href="‘+obj.url+‘">\n‘ + ‘ <p class="title">‘+obj.title+‘</p>\n‘ + ‘ <p class="className" id="className‘+i+‘"></p>\n‘ + ‘ <p class="detail" id="detail‘+i+‘"></p>\n‘ + ‘ </a>\n‘ + ‘ </td>\n‘ + ‘ </tr>‘; $(‘#searchList‘).append(lielem); if(obj.className!= null){ var spanElem=‘<span>‘+obj.className+‘</span>‘; $(‘#className‘+i).append(spanElem); } if(obj.creatTime!=null){ var emElem=‘<em>‘+obj.creatTime+‘</em>‘; $(‘#className‘+i).append(emElem); } if(obj.detail != undefined || obj.detail != null){ var detailElem=‘<p>‘+obj.detail+‘</p>‘; $(‘#detail‘+i).append(detailElem); } }) //位置1 对数据进行分页 $(‘#pageination‘).show(); pagination(3,1); }else{ $(‘#searchList‘).empty(); var strNull=‘<p style="text-align: center;line-height: 50px">暂无相关搜索结果</p>‘ + ‘<p style="text-align: center"><a href="index.html"><button id="btnback" type="button">返回首页</button></a></p>‘; $(‘#searchList‘).append(strNull); $(‘#pageination‘).hide(); } } }); } $(‘#serchId‘).on(‘keydown‘,function (event) { var e = event || window.event || arguments.callee.caller.arguments[0]; if (e && e.keyCode==13) { searchAction(); } }) //列表分页 //perPage 每一页显示条数 current:当前第几页 function pagination(perPage,current) { var tableData = document.getElementById("searchList"); var totalCount=tableData.rows.length; //总条数 //设置表格总页数 var totalPage=0;//列表的总页数 var pageSize = perPage; if (totalCount/pageSize > parseInt(totalCount/pageSize)){ totalPage = parseInt(totalCount/pageSize)+1; }else{ totalPage = parseInt(totalCount/pageSize); } //对数据进行分页 var currentPage=current; var startRow=(currentPage-1)*pageSize+1; var endRow=(currentPage*pageSize > totalCount ? totalCount : currentPage*pageSize); for(var i=1;i<(totalCount+1);i++){ var irow = tableData.rows[i-1]; if(i>=startRow && i<=endRow){ irow.style.display = "block"; }else{ irow.style.display = "none"; } } //位置2 生成当前的点击按钮 createBtns(totalPage , current); //位置3 绑定点击事件 bindClick(totalPage); } //生成点击按钮 //totalPages 分页的总页数 //current当前页 function createBtns(totalPages , current) { var tempStr = ""; /*上一页按钮*/ if (current > 1) { /* tempStr += "<span class=‘btn first‘ href=\"#\" data-page = ‘1‘>首页</span>";*/ tempStr += "<span class=‘btn prev‘ href=\"#\" data-page = "+(current-1)+">上一页</span>" } /*中间页码的显示*/ /*如果总页数超出5个处理办法*/ if(totalPages<=5){ for(var pageIndex= 1 ; pageIndex < totalPages+1; pageIndex++){ tempStr += "<a class=‘btn page"+pageIndex+"‘ data-page = "+( pageIndex )+"><span>"+ pageIndex +"</span></a>"; } }else{ if(current<5){ for(var pageIndex= 1 ; pageIndex < 5; pageIndex++){ tempStr += "<a class=‘btn page"+pageIndex+"‘ data-page = "+( pageIndex )+"><span>"+ pageIndex +"</span></a>"; } tempStr+=‘<span>......</span>‘; tempStr += "<a class=‘btn page"+totalPages+"‘ data-page = "+( totalPages )+"><span>"+ totalPages +"</span></a>"; }else if(current>= totalPages-4){ tempStr += "<a class=‘btn page"+1+"‘ data-page = "+( 1 )+"><span>"+ 1 +"</span></a>"; tempStr+=‘<span>......</span>‘; for(var pageIndex= totalPages-4 ; pageIndex <= totalPages; pageIndex++){ tempStr += "<a class=‘btn page"+pageIndex+"‘ data-page = "+( pageIndex )+"><span>"+ pageIndex +"</span></a>"; } }else if(current>=5 && current <totalPages-4){ tempStr += "<a class=‘btn page"+1+"‘ data-page = "+( 1 )+"><span>"+ 1 +"</span></a>"; tempStr+=‘<span>......</span>‘; for(var pageIndex= current ; pageIndex <= current+4; pageIndex++){ tempStr += "<a class=‘btn page"+pageIndex+"‘ data-page = "+( pageIndex )+"><span>"+ pageIndex +"</span></a>"; } tempStr+=‘<span>......</span>‘; tempStr += "<a class=‘btn page"+totalPages+"‘ data-page = "+( totalPages )+"><span>"+ totalPages +"</span></a>"; } } /*下一页按钮*/ if (current < totalPages) { tempStr += "<span class=‘btn next‘ href=\"#\" data-page = "+(current+1)+">下一页</span>";/* tempStr += "<span class=‘btn last‘ href=\"#\" data-page = "+ (totalPages) +">尾页</span>";*/ } document.getElementById("pageination").innerHTML = tempStr; } function bindClick(totalPage) { // 设置首页、末页、上一页、下一页的点击事件 var buttonArr = [‘first‘,‘last‘,‘prev‘,‘next‘]; for(var k in buttonArr){ var $dom = ‘.‘+buttonArr[k]; $(‘body‘).delegate( $dom , ‘click‘ , function () { var data = $(this).data(‘page‘);//获取当前按钮跳转的页数 pagination(‘3‘ , data);//对页面进行分页 //对当前页码的样式做处理 $(‘.page‘+data).css({background:‘#0449d4‘,color:‘#fff‘}).siblings().css({background:‘#fff‘,color:‘#999‘}); }) } // 设置数码的点击事件 totalImgPage是总页数,为全局变量,在分页时被赋值 for (var k = 1 ;k <= totalPage ; k++){ var $singleDom = ‘.page‘+k; $(‘body‘).delegate( $singleDom , ‘click‘ , function () { var data = $(this).data(‘page‘); pagination(‘3‘ , data);//对页面进行分页 //对当前页码的样式做处理 $(‘.page‘+data).css({background:‘#0449d4‘,color:‘#fff‘}).siblings().css({background:‘#fff‘,color:‘#999‘}); }) } }
基于jq复制完整代码此分页功还是能实现的,也展示的分页的原理,若有大神改进,望瞻仰!
