实现的效果样式
一、bootstrap分页插件，bootstrap-paginator.js里面的内容是我自己修改之后的，可以再网上下载一个版本修改成自己的样式

二、前端代码
1、HTML代码
/* 高亮显示*/
#pageLimit .active a{
background-color: #42a5f5;
border-color: #42a5f5;
color:#fff;
}
<!--右侧是查询出来的文件列表 --> <div id="right-div"> <ul class="law-content-con" id="showList"> </ul> <!--分页组件 --> <div align="center"> <ul id="pageLimit" style="padding:30px 260px;"></ul> </div> </div>
2、js文件
init:function() {
// 总条数
var total;
// 每页显示数量
var pageSize=10;
// 总页数
var pages;
// 显示页数
var numberOfPages;
// 关键字
var keyName=window.localStorage.getItem("keyName");
$.ajax({
type: "post",
cache: false,
url: backbasePath+'/apia/v1/file/kNowledgeList',
dataType:"json",
data:{// 当前的页数
currentPageName:1,
// 每页显示的条数
pageSizeName:pageSize,
},
async: true,
success: function(data) {
if('000000'==data.code){
// 获取数据信息
var infoJson=data.data;
// 获取总共的条数
total=data.total;
pages=Math.ceil(total/pageSize);
if(total > 0 ){
if(pages < numberOfPages){
numberOfPages=pages;
}
// 插件的各项设置
var options = {
// 当前的请求页面
currentPage:1,
totalPages:pages,
bootstrapMajorVersion:3,
size:"normal",
alignment:"center",
itemTexts: function (type, page, current) {
switch (type) {
case "prev":
return "上页";
case "next":
return "下页";
case "page":
return page;
}
},
onPageClicked: function(event, originalEvent, type, page){
if(page=="up" || page=="down"){
return;
}else{
$.post(backbasePath+'/apia/v1/file/kNowledgeList',
{
currentPageName:page,
// 每页显示的条数
pageSizeName:pageSize,
},
function (map) {
var infoJson = map.data;
kNowledgeList.show(infoJson);
},
"json"
);
}
}
}
$('#pageLimit').bootstrapPaginator(options);
}
kNowledgeList.show(infoJson);
} else {
toastr.error(data.msg);
}
},
error: function () {
toastr.error('知识库检索失败！！');
}
});
},
三、后端代码
// 查询当前人所在部门上传的文件 public String kNowledgeList(HttpServletRequest req){ String result=""; try { // 封装前台参数为map Map<String, Object> m = getMaps(req); // 当前页 int currentPage =Integer.parseInt(req.getParameter("currentPageName")); // 每页显示数量 int pageSize =Integer.parseInt(req.getParameter("pageSizeName")); log.info("|" + m + "|");// 获取知识表中数据的个数 int total = kNowledgeDao.kNowledgeCount(m);
// 对应的分页方法，当前页数以及每页数量，limit pageHelper.startPage(currentPage, pageSize); List<Map<String, Object>> dataList = kNowledgeDao.kNowledgeList(m); // 获取的集合列表转换成json格式 String dataListStr = StringTool.listToJson(dataList); StringBuffer sb = new StringBuffer(); sb.append("{"); sb.append("" + getKey("code") + ":" + getKey(RespCode.commonSucc) + ","); sb.append("" + getKey("msg") + ":" + getKey(RespMsg.commonSucc) + ","); sb.append("" + getKey("total") + ":" + total + ","); // 将数据列表放在data参数里面 sb.append("" + getKey("data") + ":" + dataListStr); sb.append("}"); result = sb.toString(); } catch (Exception e) { rollBack(e, log); } log.info("|" + result + "|"); return result; }
