一开始写项目的时候,没用ajax,导致做搜索分页功能的时候废了好大的劲,在这里分享一下处理这个问题的思路。
框架用的springboot,通过thymeleaf模板和前端交互,没有使用ajax,所以数据都是在域对象放的。分页用的springdatajpa的分页,他个其他的分页工具大同小异,优点在于不用在引入新的依赖,直接通过查询得到的就是Page对象,缺点就是springdatajpa自带的分页工具其起始页是从0开始的,这一点比较恶心,哈哈。
主要思路就是把搜索条件和分页的请求地址都在域中定义,然后再js方法中得到这些信息,发送请求的时候调用js方法,拼接带搜索条件的参数。
--page分页-- 代码写的啰嗦,抽时间优化一下
<div class="box-footer" th:fragment="page" xmlns:th="http://www.thymeleaf.org"> <div class="modal-footer no-margin-top"> <div class="pull-left"> <div class="form-group form-inline"> 总共<span th:text="${page.totalPages}"></span> 页,共<span th:text="${page.totalElements}"></span> 条数据。 </div> </div> <div class="page"> <ul class="pagination" th:if="${page.totalPages le 8 && page.totalPages gt 1}"> <!-- 上一页 --> <li class="page-item" th:if="${page.pageable.getPageNumber() != 0}"> <a th:onclick="pageRequest([[${page.pageable.getPageNumber()-1}]])" class="page-link" data-th-attr="pageIndex=${page.number} - 1" aria-label="Previous"> <span aria-hidden="true">«</span> </a> </li> <!-- 迭代生成页码 --> <li th:if="${page.totalPages gt 1}" class="page-item" data-th-each="i : ${#numbers.sequence(1, page.totalPages)}" data-th-classappend="${(page.number + 1) eq i} ? ‘active‘ : ‘‘" > <a class="page-link" th:onclick="pageRequest([[${i}-1]])"> <span data-th-text="${i}"></span> </a> </li> <!-- 下一页 --> <li class="page-item" th:if="${page.pageable.pageNumber} != ${page.totalPages}-1"> <a class="page-link" th:onclick="pageRequest([[${page.pageable.pageNumber}+1]])"> » </a> </li> </ul> <!-- 处理页数大于7 的情况 --> <ul class="pagination" data-th-if="${page.totalPages gt 7}" > <!-- 上一页 --> <li class="page-item" data-th-if="${page.pageable.getPageNumber() != 0}"> <a th:onclick="pageRequest([[${page.pageable.getPageNumber()-1}]])" class="page-link" data-th-attr="pageIndex=${page.number} - 1" aria-label="Previous"> <span aria-hidden="true">«</span> </a> </li> <!-- 首页 --> <li class="page-item" data-th-classappend="${(page.number + 1) eq 1} ? ‘active‘ : ‘‘" > <a th:onclick="pageRequest(0)" class="page-link" data-th-attr="pageIndex=0">1</a> </li> <!-- 当前页面小于等于4 --> <li class="page-item" data-th-if="${(page.number + 1) le 4}" data-th-each="i : ${#numbers.sequence(2,5)}" data-th-classappend="${(page.number + 1) eq i} ? ‘active‘ : ‘‘" > <a class="page-link" th:onclick="pageRequest([[${i-1}]]) " data-th-attr="pageIndex=${i} - 1"> <span data-th-text="${i}"></span> </a> </li> <li class="page-item disabled" data-th-if="${(page.number + 1) le 4}"> <a class="page-link"> <span aria-hidden="true">...</span> </a> </li> <!-- 最后一页与当前页面之差,小于等于3 --> <li class="page-item disabled" data-th-if="${(page.totalPages-(page.number + 1)) le 3}"> <a class="page-link"> <span aria-hidden="true">...</span> </a> </li> <li class="page-item" data-th-if="${(page.totalPages-(page.number + 1)) le 3}" data-th-each="i : ${#numbers.sequence(page.totalPages-4, page.totalPages-1)}" data-th-classappend="${(page.number + 1) eq i} ? ‘active‘ : ‘‘" > <a class="page-link" th:onclick="pageRequest([[${i-1}]])" data-th-attr="pageIndex=${i} - 1"> <span data-th-text="${i}"></span> </a> </li> <!-- 最后一页与当前页面之差大于3,且 当前页面大于4--> <li class="page-item disabled" data-th-if="${((page.number + 1) gt 4) && ((page.totalPages-(page.number + 1)) gt 3 )}"> <a class="page-link"> <span aria-hidden="true">...</span> </a> </li> <li class="page-item" data-th-if="${((page.number + 1) gt 4) && ((page.totalPages-(page.number + 1)) gt 3 )}" data-th-each="i : ${#numbers.sequence(page.number, page.number+3)}" data-th-classappend="${(page.number + 1) eq i} ? ‘active‘ : ‘‘"> <a th:onclick="pageRequest([[${i-1}]])" class="page-link" data-th-attr="pageIndex=${i} - 1"><span data-th-text="${i}"></span></a> </li> <li class="page-item disabled" data-th-if="${((page.number + 1) gt 4) && ((page.totalPages-(page.number + 1)) gt 3 )}"> <a class="page-link"> <span aria-hidden="true">...</span> </a> </li> <!-- 最后一页 --> <!-- <li class="page-item" data-th-classappend="${(page.number + 1) eq page.totalPages} ? ‘active‘ : ‘‘" >--> <!-- <a th:onclick="pageRequest([[${page.getTotalPages() - 1}]])" class="page-link" data-th-attr="pageIndex=${page.totalPages} - 1">[[${page.totalPages}]]</a>--> <!-- </li>--> <li class="page-item" data-th-classappend="${(page.number + 1) eq page.totalPages} ? ‘active‘ : ‘‘"> <a th:onclick="pageRequest([[${page.getTotalPages() - 1}]])" class="page-link" >[[${page.totalPages}]]</a> </li> <!-- 下一页 --> <li class="page-item" th:if="${page.pageable.pageNumber} != ${page.totalPages}-1"> <a class="page-link" th:onclick="pageRequest([[${page.pageable.pageNumber}+1]])"> » </a> </li> </ul> </div> </div> </div>
代码中,请求的地方调用了js方法,因为请求是不固定的,所以js中具体定义请求的路劲。
function pageRequest(param) {var url = ‘[[${url}]]‘;//这个写法可以把域中的地址拿到 请求是后端转发到前端(不是重定向) url = url.replace(‘&‘,‘&‘);//这个是个bug,后端放到域中的&到前端之后被转义成&; 了,所以我在这里在替换一下
var search = ‘[[${search}]]‘ //获取域中的搜索条件 var url1 = url+param+‘&search=‘+serach; //alert(url); location.assign(url1) }
controller层代码
@RequestMapping("/list") public String all(String search,Model model, @RequestParam(defaultValue = "0")Integer pageNum,@RequestParam(defaultValue = "1") Integer requestStatus){ model.addAttribute("url","/workOrder/list?requestStatus="+requestStatus+"&pageNum="); Page<WorkOrder> page = null; switch (requestStatus){ case 1://全部 page = workOrderService.search(workOrder,pageNum,10); model.addAttribute("class","1");//用于按钮状态回显 我再前端有判断 break; case 2://本人发起 page = workOrderService.findPageMyWorkOrder(pageNum, 10); model.addAttribute("class","2"); break; case 3://处理中 page = workOrderService.findPageUnSuccessWorkOrder(pageNum, 10); model.addAttribute("class","3"); break; case 4://已完成 page = workOrderService.findPageSuccessWorkOrder(pageNum, 10); model.addAttribute("class","4"); break; default: break; } model.addAttribute(search); model.addAttribute("page",page);//包含分页的信息和查询到的信息 return "workOrder-list"; }
