一. 代碼

fun.js

function saveType(typename, username){  if(typename==''){   //判斷部落格類別是否為空白    alert('請輸入類別名稱！');  }else if(username==''){   //判斷使用者名稱是否為空白    alert('請輸入使用者名稱！');  }else{    var xmlObj;   //定義XMLHttpRequest對象    var urlData = "typename="+typename+"&username="+username;    //指定要發送的資料    if(window.ActiveXObject){   //判斷瀏覽器是否支援ActiveXObject組件，如支援則通過ActiveXObject方式建立XMLHttpRequest對象      xmlObj = new ActiveXObject("Microsoft.XMLHTTP");    }else if(window.XMLHttpRequest){   //如果瀏覽器不支援ActiveXObject組件，則使用XMLHttpRequest組件建立XMLHttpRequest對象      xmlObj = new XMLHttpRequest();    }    xmlObj.onreadystatechange = callBackFun;   //指定回呼函數    xmlObj.open("POST", "saveType.php", true);   //指定提交方法和頁面    xmlObj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;");   //指定發送資料庫類型    xmlObj.send(urlData);   //指定發送的資料    function callBackFun(){   //定義回呼函數      if(xmlObj.readyState == 4 && xmlObj.status == 200){   //如果伺服器端返回內容並無錯誤發生        if(xmlObj.responseText == 'y'){  //判斷儲存是否成功，並給出提示          alert('類別添加成功！');        }else{          alert('類別添加失敗！');        }      }    }  }}

conn.php

<?php$host = '127.0.0.1';$userName = 'root';$password = 'root';$connID = mysql_connect($host, $userName, $password);mysql_select_db('db_database27', $connID);mysql_query('set names gbk');?>
