java ajax json 分页_使用Jquery+Ajax+Json如何实现分页显示附JAVA+JQuery实现异步分页

1.后台action产生json数据。

List blackList = blackService.getBlackInfoList(mobileNum, gatewayid, startDate, endDate);

int totalRows = blackList.size();

StringBuffer sb = new StringBuffer();

sb.append("{\"totalCount\":\""+totalRows+"\",");

sb.append("\"jsonRoot\":[");

for (int i=0;i

LBlack blackInfo = (LBlack)blackList.get(i);

sb.append("{\"id\":\""+ blackInfo.getId());

sb.append("\",");

sb.append("\"mobile\":\""+ blackInfo.getMobile());

sb.append("\",");

sb.append("\"province\":\""+ blackInfo.getProvince());

sb.append("\",");

sb.append("\"gateway\":\""+ blackInfo.getGateway());

sb.append("\",");

sb.append("\"insertTime\":\""+ blackInfo.getInsertTime());

sb.append("\",");

sb.append("\"remark\":\""+ blackInfo.getRemark());

sb.append("\"");

sb.append("},");

}

sb.deleteCharAt(sb.lastIndexOf(",")); // 删去最后一个逗号

sb.append("]}");

HttpServletResponse response = ServletActionContext.getResponse();

response.setContentType("text/plain");

response.getWriter().print(sb);

2.struts.xml相关配置

UTF-8

/WEB-INF/jsp/manage/black.jsp

3.js获取json数据分页显示

function getJSONData(pn) {

// alert(pn);

$.getJSON("blackList.ce", function(data) {

var totalCount = data.totalCount; // 总记录数

var pageSize = 10; // 每页显示几条记录

var pageTotal = Math.ceil(totalCount / pageSize); // 总页数

var startPage = pageSize * (pn - 1);

var endPage = startPage + pageSize - 1;

var $ul = $("#json-list");

$ul.empty();

for (var i = 0; i < pageSize; i++) {

$ul.append('

');

}

var dataRoot = data.jsonRoot;

if (pageTotal == 1) { // 当只有一页时

for (var j = 0; j < totalCount; j++) {

$(".li-tag").eq(j).append("")

.append("" + parseInt(j + 1)

+ "").append("" + dataRoot[j].mobile

+ "").append("" + dataRoot[j].province

+ "").append("" + dataRoot[j].gateway

+ "").append("" + dataRoot[j].insertTime

+ "").append("" + dataRoot[j].remark

+ "")

}

} else {

for (var j = startPage, k = 0; j < endPage, k < pageSize; j++, k++) {

if( j == totalCount){

break; // 当遍历到最后一条记录时,跳出循环

}

$(".li-tag").eq(k).append("")

.append("" + parseInt(j + 1)

+ "").append("" + dataRoot[j].mobile

+ "").append("" + dataRoot[j].province

+ "").append("" + dataRoot[j].gateway

+ "").append("" + dataRoot[j].insertTime

+ "").append("" + dataRoot[j].remark

+ "")

}

}

$(".page-count").text(pageTotal);

})

}

function getPage() {

$.getJSON("blackList.ce", function(data) {

pn = 1;

var totalCount = data.totalCount; // 总记录数

var pageSize = 10; // 每页显示几条记录

var pageTotal = Math.ceil(totalCount / pageSize); // 总页数

$("#next").click(function() {

if (pn == pageTotal) {

alert("后面没有了");

pn = pageTotal;

} else {

pn++;

gotoPage(pn);

}

});

$("#prev").click(function() {

if (pn == 1) {

alert("前面没有了");

pn = 1;

} else {

pn--;

gotoPage(pn);

}

})

$("#firstPage").click(function() {

pn = 1;

gotoPage(pn);

});

$("#lastPage").click(function() {

pn = pageTotal;

gotoPage(pn);

});

$("#page-jump").click(function(){

if($(".page-num").val() <= pageTotal && $(".page-num").val() != ''){

pn = $(".page-num").val();

gotoPage(pn);

}else{

alert("您输入的页码有误!");

$(".page-num").val('').focus();

}

})

$("#firstPage").trigger("click");

})

}

function gotoPage(pn) {

// alert(pn);

$(".current-page").text(pn);

getJSONData(pn)

}

$(function() {

getPage();

})

ps:JAVA+JQuery实现异步分页

最近一个项目要求实现异步分页,简单的写了一下,不好的请指出~

public class PageBean {

publicint rowCount = 0; // 总记录数

publicint currentPage = 1;// 当前页数

publicint sizePerPage = 20;// 每页显示条数

publicint pageCount = 0;// 总页数

publicString pageURL;// 请求URL

publicString pageDisplay;// JSP页面显示

publicString pageStyle = "numberStyle";// 分页样式

publicint pagePreOffset = 10;// 向前偏移量

publicint pageNextOffset = 9;// 向后偏移量

publicString pageCss;// 预留

publicString getPageCss() {

returnpageCss;

}

publicvoid setPageCss(String pageCss) {

this.pageCss = pageCss;

}

publicString getPageStyle() {

returnpageStyle;

}

publicvoid setPageStyle(String pageStyle) {

this.pageStyle = pageStyle;

}

publicint getPagePreOffset() {

returnpagePreOffset;

}

publicvoid setPagePreOffset(intpagePreOffset) {

this.pagePreOffset = pagePreOffset;

String firstClick=" οnclick='ajaxpage(""+this.pageURL+ "?currentPage=1");return false;' ";

String lastClick=" οnclick='ajaxpage(""+this.pageURL+ "?currentPage=" + (this.getPageCount())+"");return false;' ";

String onChange=" οnchange='ajaxpage(""+this.pageURL+ "?currentPage=" + (1)+"");return false;' ";

StringBuffer pageString =new StringBuffer();

pageString.append("

");

// 数字样式

if("numberStyle".equalsIgnoreCase(this.pageStyle)) {

// 如果只有一页,不需要分页

if(this.getPageCount() ==1) {

// pageString.append(" 1 ");

}else {

if(this.currentPage >1) {// 如果当前页数大于1,<<

pageString.append("<< ");

pageString.append("< ");

}else {

pageString

.append("<< ");

pageString

.append("< ");

}

// 定义向前偏移量

intpreOffset = this.currentPage -1 > this.pagePreOffset ?this.pagePreOffset

:this.currentPage -1;

// 定义向后偏移量

intnextOffset = this.getPageCount() -this.currentPage >this.pageNextOffset ?this.pageNextOffset

:this.getPageCount() -this.currentPage;

// 循环显示链接数字,范围是从 当前页减向前偏移量 到 当前页加向后偏移量

for(int i = (this.currentPage - preOffset); i <= (this.currentPage + nextOffset); i++) {

String numClick=" οnclick='ajaxpage(""+this.pageURL+ "?currentPage=" + (i)+"");return false;' ";

if(this.currentPage == i) {// 当前页要加粗显示

pageString

.append(""

+ i +" ");

}else {

pageString.append("

+"?currentPage=" + i + "'>" + i +"

");

}

}

// 如果当前页小于总页数,> >>可用

if(this.currentPage

pageString.append("> ");

pageString.append(">> ");

}else {

pageString

.append("> ");

pageString

.append(">> ");

}

pageString.append(""+this.getOptions()+"");

}else if("normalStyle".equalsIgnoreCase(this.pageStyle)) {

}else {
