這篇文章主要介紹了PHP實(shí)現(xiàn)從PostgreSQL數(shù)據(jù)庫(kù)檢索數(shù)據(jù)分頁(yè)顯示及根據(jù)條件查找數(shù)據(jù)操作,涉及PHP操作PostgreSQL數(shù)據(jù)庫(kù)的SQL條件查詢、分頁(yè)、顯示等相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了PHP實(shí)現(xiàn)從PostgreSQL數(shù)據(jù)庫(kù)檢索數(shù)據(jù)分頁(yè)顯示及根據(jù)條件查找數(shù)據(jù)。分享給大家供大家參考，具體如下：

主要功能是從postgreSql查詢數(shù)據(jù)，并檢索，由于自己剛開(kāi)始接觸，所以難點(diǎn)在于多條數(shù)據(jù)同時(shí)篩選并分頁(yè)顯示出來(lái)，寫(xiě)下自己的代碼與大家共享。

<html>
<head>
<script type="text/javascript">
  /**
 * 分頁(yè)函數(shù)
 * pno--頁(yè)數(shù)
 * psize--每頁(yè)顯示記錄數(shù)
 * 分頁(yè)部分是從真實(shí)數(shù)據(jù)行開(kāi)始，因而存在加減某個(gè)常數(shù)，以確定真正的記錄數(shù)
 * 純js分頁(yè)實(shí)質(zhì)是數(shù)據(jù)行全部加載，通過(guò)是否顯示屬性完成分頁(yè)功能
 **/
function goPage(pno,psize){
  var itable = document.getElementById("idData");
  var num = itable.rows.length;//表格所有行數(shù)(所有記錄數(shù))
  console.log(num);

  var pageSize = psize;//每頁(yè)顯示行數(shù)
  //總共分幾頁(yè)

    }else{

    }
  var currentPage = pno;//當(dāng)前頁(yè)數(shù)
  var startRow = (currentPage - 1) * pageSize+1;//開(kāi)始顯示的行 31
    var endRow = currentPage * pageSize;//結(jié)束顯示的行  40
    endRow = (endRow > num)? num : endRow;  40
    console.log(endRow);
    //遍歷顯示數(shù)據(jù)實(shí)現(xiàn)分頁(yè)
  for(var i=1;i<(num+1);i++){
    var irow = itable.rows[i-1];
    if(i>=startRow && i<=endRow){
      irow.style.display = "block";
