使用$.ajax()方法处理json数据格式，后台传过来的json格式，通过jquery中的$.ajax()之后没有结果。传过来的json格式是这样的{"infos":[{"id":402881e9564b22f701564b251aef0001,"title":"火影","publishingTime":"2016-08-02 20:05:38.0","isEditable":"true"},{"id":402881e9565a7f3601565a86f0c30001,"title":"龙珠","publishingTime":"2016-08-05 19:46:48.0","isEditable":"true"},{"id":402881e9565a7f3601565a8720ac0002,"title":"哈哈","publishingTime":"2016-08-05 19:47:00.0","isEditable":"true"},{"id":402881e9565a7f3601565a87464b0003,"title":"海贼","publishingTime":"2016-08-05 19:47:10.0","isEditable":"true"},{"id":402881e9565a7f3601565a87b47c0004,"title":"海贼王","publishingTime":"2016-08-05 19:47:38.0","isEditable":"true"}],"pageBean":{"pageSize":5,"currentPage":1,"totalPage":1,"hasPrevious":false,"HasNext":false}}那个jquery的$.ajax()是这样写的$(function () { $.post("getFirstInfoList.action", null, function (data) { var totalPage = data.totalPage; PageClick(1, totalPage, 3); }); PageClick = function (page, totalPage, spanInterval) { $.ajax({ url: "getFirstInfoList.action", data: { "page": page }, type: "post", dataType: "json", success: function (data) { //索引从1开始 //将当前页索引转为int类型 var intPageIndex = parseInt(page); //获取显示数据的表格 var table = $("#content"); //清楚表格中内容 $("#content tr").remove(); var infos=data.infos; //向表格中添加内容 for (var i = 0; i < infos.length; i++) { table.append( $("<tr><td>" + infos[i].id + "</td><td>" + infos[i].title + "</td><td>" + infos[i].publishingTime + "</td><td>" + infos[i].isEditable + "</td></tr>") ); } //for //创建分页 //将总记录数结果 得到 总页码数 var pageS = data.totalPage; var $pager = $("#pager"); //清楚分页div中的内容 $("#pager span").remove(); $("#pager a").remove(); //添加第一页 if (intPageIndex == 1) $pager.append("<span class='disabled'>第一页</span>"); else { var first = $("<a href='javascript:void(0)' first='" + 1 + "'>第一页</a>").click(function () { PageClick($(this).attr('first'), totalPage, spanInterval); return false; }); $pager.append(first); } //添加上一页 if (intPageIndex == 1) $pager.append("<span class='disabled'>上一页</span>"); else { var pre = $("<a href='javascript:void(0)' pre='" + (intPageIndex - 1) + "'>上一页</a>").click(function () { PageClick($(this).attr('pre'), totalPage, spanInterval); return false; }); $pager.append(pre); } //设置分页的格式 这里可以根据需求完成自己想要的结果 var interval = parseInt(spanInterval); //设置间隔 var start = Math.max(1, intPageIndex - interval); //设置起始页 var end = Math.min(intPageIndex + interval, pageS)//设置末页 if (intPageIndex < interval + 1) { end = (2 * interval + 1) > pageS ? pageS : (2 * interval + 1); } if ((intPageIndex + interval) > pageS) { start = (pageS - 2 * interval) < 1 ? 1 : (pageS - 2 * interval); } //生成页码 for (var j = start; j < end + 1; j++) { if (j == intPageIndex) { var spanSelectd = $("<span class='current'>" + j + "</span>"); $pager.append(spanSelectd); } //if else { var a = $("<a href='javascript:void(0)'>" + j + "</a>").click(function () { PageClick($(this).text(), totalPage, spanInterval); return false; }); $pager.append(a); } //else } //for //上一页 if (intPageIndex == totalPage) { $pager.append("<span class='disabled'>下一页</span>"); } else { var next = $("<a href='javascript:void(0)' next='" + (intPageIndex + 1) + "'>下一页</a>").click(function () { PageClick($(this).attr("next"), totalPage, spanInterval); return false; }); $pager.append(next); } //最后一页 if (intPageIndex == pageS) { $pager.append("<span class='disabled'>最后一页</span>"); } else { var last = $("<a href='javascript:void(0)' last='" + pageS + "'>最后一页</a>").click(function () { PageClick($(this).attr("last"), totalPage, spanInterval); return false; }); $pager.append(last); } } //sucess }); //ajax }; //function }); //ready 为啥经过这个jquery之后就没数据了
