本文主要为大家分享一篇Vue.js如何实现真分页的问题，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧。
前端在初始化过程中，第一步先请求总的条数，然后，再请求第一页数据，然后根据点击翻页事件根据请求页码用ajax（axios和qs）去后台取得数据。
<span style="font-family: 微软雅黑, "Microsoft YaHei";">pagerData:{<br/> data:[],<br/> page:{<br/> //分页数<br/> arrPageSize:[10,20,30,40],<br/> //分页大小<br/> pageSize:10,<br/> //总分页数<br/> pageCount:1,<br/> //当前页面<br/> pageCurrent:1,<br/> //总数<br/> totalCount:80<br/> }<br/> },<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";"> @Override<br/> public List<A> getPageList(int startpage, int endpage) throws IOException {<br/> // TODO Auto-generated method stub<br/> init();<br/> List<A> list = aMapper.selectByPage(startpage,endpage,null);<br/> return list;<br/> }<br/><br/> @Override<br/> public Integer getCount() throws IOException {<br/> // TODO Auto-generated method stub<br/> init();<br/> Integer count = (int) aMapper.countByExample(null);<br/> return count;<br/> }<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";">created(){<br/> //请求总页数<br/> this.$axios.post("http://localhost:8088/Web/ListServlet",<br/> {params:{<br/> init:true<br/> }}<br/> ,<br/> {<br/> headers:{'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}<br/> }<br/> )<br/> .then(res=>{<br/> console.log(JSON.stringify(res.data));<br/> var object = eval(res.data);<br/> var totalNum = object["count"];<br/> console.log("totalNum:" + totalNum);<br/> this.pagerData.page.totalCount = totalNum;<br/> });}<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";">String queryString = readRequest(request);<br/> <br/> JSONObject object = null;<br/> object = JSONObject.fromObject(queryString);<br/> JSONObject params = (JSONObject) object.get("params");<br/> //判断是是初始化过程<br/> if((params.getString("init")).equals("true")) {<br/> Integer count = service.getCount();<br/> PrintWriter out = response.getWriter();<br/> JSONObject result = new JSONObject();<br/> result.put("count", count);<br/> logger.info(result.toString());<br/> out.write(result.toString());<br/> out.close();<br/> return;<br/> }<br/> logger.info(params.get("startpage"));<br/> logger.info(params.get("endpage"));<br/> //判断不是初始化过程<br/> if((params.getString("init")).equals("false")) {<br/> PrintWriter out = response.getWriter();<br/> List<A> list = service.getPageList(Integer.parseInt((params.getString("startpage"))),<br/> Integer.parseInt((params.getString("endpage"))));<br/> JSONArray array = JSONArray.fromObject(list);<br/> out.write(array.toString());<br/> out.close();<br/> return;<br/> }<br/>public String readRequest(HttpServletRequest request) throws IOException {<br/> BufferedReader reader = new BufferedReader(new InputStreamReader(request.getInputStream(),"UTF-8"));<br/> String temp = "";<br/> String s = "";<br/> while((temp = reader.readLine()) != null)<br/> {<br/> s = s + temp;<br/> }<br/> return s;<br/> }<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";">//请求首页 1-10<br/> this.$axios.post("http://localhost:8088/Web/ListServlet",<br/> <br/> {params:{<br/> init:false,<br/> startpage:1,<br/> endpage:10<br/> }}<br/> ,<br/> {<br/> headers:{'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}<br/> }<br/> )<br/> .then(res=>{<br/> console.log(JSON.stringify(res.data));<br/> var object = eval(res.data);<br/> var totalNum = object["count"];<br/> console.log("totalNum:" + totalNum);<br/> for(var i = 0; i < res.data.length; i++){<br/> //console.log("res.data[i] is " + i + "\n " + JSON.stringify(res.data[i]));<br/> var object = eval(res.data[i]);<br/> object.index = i+1;<br/> totalNum ++;<br/> if(i<=10){ //初始化获取数据的过程中，将前10个默认加入分页data<br/> this.pagerData.data.push(object);<br/> }<br/> }<br/> //this.pagerData.page.totalCount = totalNum;<br/> });<br/> this.loading = false;<br/> <br/> <br/> }<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";">this.$axios.post('http://localhost:8088/Web/ListServlet',<br/> {params:{<br/> init:false,<br/> startpage:((curpage-1)*this.pagerData.page.pageSize +1),<br/> endpage:curpage*this.pagerData.page.pageSize<br/> }},<br/> {<br/> headers:{'Content-Type':'application/x-www-form-urlencoded;charset=utf-8'}<br/> }<br/> ).then(res=>{<br/> console.log(JSON.stringify(res.data));<br/> var object = eval(res.data);<br/> for(var i = 0; i < res.data.length; i++){<br/> //console.log("res.data[i] is " + i + "\n " + JSON.stringify(res.data[i]));<br/> var object = eval(res.data[i]);<br/> object.index = (curpage-1)*this.pagerData.page.pageSize +1 + i;<br/> if(i<=this.pagerData.page.pageSize){<br/> this.pagerData.data.push(object);<br/> }<br/> }<br/> //this.pagerData.page.totalCount = totalNum;<br/> })<br/></span><span style="font-family: 微软雅黑, "Microsoft YaHei";">//判断不是初始化过程<br/> if((params.getString("init")).equals("false")) {<br/> PrintWriter out = response.getWriter();<br/> List<A> list = service.getPageList(Integer.parseInt((params.getString("startpage"))),<br/> Integer.parseInt((params.getString("endpage"))));<br/> JSONArray array = JSONArray.fromObject(list);<br/> //logger.info(array.get(1).toString());<br/> out.write(array.toString());<br/> out.close();<br/> return;<br/> }<br/></span> 可添加配置：pageSize，从前台传入后台，修改分页大小
example，条件查询，可在params里配置，用mybatis example配置查询
这是一个比较原生的真分页方法，如果想要实现更加复杂的分页，需要使用相关分页插件。
