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<blackList.size();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
<action name="blackList" class="blackAction" method="blackList">
<!--plaintext用于显示页面原始代码的结果类型-->
<result type="plainText">
<param name="charSet">UTF-8</param>
<param name="location">/WEB-INF/jsp/manage/black.jsp</param>
</result>
</action>
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('<li class="li-tag"></li>');
}
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("<span class='col1'><input type='checkbox' value='"+parseInt(j + 1)+"'/></span>")
.append("<span class='col2'>" + parseInt(j + 1)
+ "</span>").append("<span class='col3'>" + dataRoot[j].mobile
+ "</span>").append("<span class='col4'>" + dataRoot[j].province
+ "</span>").append("<span class='col5'>" + dataRoot[j].gateway
+ "</span>").append("<span class='col6'>" + dataRoot[j].insertTime
+ "</span>").append("<span class='col7'>" + dataRoot[j].remark
+ "</span>")
}
} 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("<span class='col1'><input type='checkbox' value='"+parseInt(j + 1)+"'/></span>")
.append("<span class='col2'>" + parseInt(j + 1)
+ "</span>").append("<span class='col3'>" + dataRoot[j].mobile
+ "</span>").append("<span class='col4'>" + dataRoot[j].province
+ "</span>").append("<span class='col5'>" + dataRoot[j].gateway
+ "</span>").append("<span class='col6'>" + dataRoot[j].insertTime
+ "</span>").append("<span class='col7'>" + dataRoot[j].remark
+ "</span>")
}
}
$(".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);
Technorati 标签: json数据
}
});
$("#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();
})
