本文实例讲述了PHP实现从PostgreSQL数据库检索数据分页显示及根据条件查找数据。分享给大家供大家参考，具体如下：
主要功能是从postgreSql查询数据，并检索，由于自己刚开始接触，所以难点在于多条数据同时筛选并分页显示出来，写下自己的代码与大家共享。
<html>
<head>
<script type="text/javascript">
/**
* 分页函数
* pno--页数
* psize--每页显示记录数
* 分页部分是从真实数据行开始，因而存在加减某个常数，以确定真正的记录数
* 纯js分页实质是数据行全部加载，通过是否显示属性完成分页功能
**/
function goPage(pno,psize){
var itable = document.getElementById("idData");
var num = itable.rows.length;//表格所有行数(所有记录数)
console.log(num);
var totalPage = 0;//总页数
var pageSize = psize;//每页显示行数
//总共分几页
if(num/pageSize > parseInt(num/pageSize)){
totalPage=parseInt(num/pageSize)+1;
}else{
totalPage=parseInt(num/pageSize);
}
var currentPage = pno;//当前页数
var startRow = (currentPage - 1) * pageSize+1;//开始显示的行 31
var endRow = currentPage * pageSize;//结束显示的行 40
endRow = (endRow > num)? num : endRow; 40
console.log(endRow);
//遍历显示数据实现分页
for(var i=1;i<(num+1);i++){
var irow = itable.rows[i-1];
if(i>=startRow && i<=endRow){
irow.style.display = "block";
}else{
irow.style.display = "none";
}
}
var pageEnd = document.getElementById("pageEnd");
var tempStr = "共"+num+"条记录 分"+totalPage+"页 当前第"+currentPage+"页";
if(currentPage>1){
tempStr += "<a href=\"#\" onClick=\"goPage("+(1)+","+psize+")\">首页</a>";
tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage-1)+","+psize+")\"><上一页</a>"
}else{
tempStr += "首页";
tempStr += "<上一页";
}
if(currentPage<totalPage){
tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage+1)+","+psize+")\">下一页></a>";
tempStr += "<a href=\"#\" onClick=\"goPage("+(totalPage)+","+psize+")\">尾页</a>";
}else{
tempStr += "下一页>";
tempStr += "尾页";
}
document.getElementById("barcon").innerHTML = tempStr;
}
