本文实例讲述了PHP+Ajax实现的博客文章添加类别功能。分享给大家供大家参考,具体如下:
一. 代码
fun.js
function saveType(typename, username){ if(typename==''){ //判断博客类别是否为空 alert('请输入类别名称!'); }else if(username==''){ //判断用户名是否为空 alert('请输入用户名!'); }else{ var xmlObj; //定义XMLHttpRequest对象 var urlData = "typename="+typename+"username="+username; //指定要发送的数据 if(window.ActiveXObject){ //判断浏览器是否支持ActiveXObject组件,如支持则通过ActiveXObject方式创建XMLHttpRequest对象 xmlObj = new ActiveXObject("Microsoft.XMLHTTP"); }else if(window.XMLHttpRequest){ //如果浏览器不支持ActiveXObject组件,则使用XMLHttpRequest组件创建XMLHttpRequest对象 xmlObj = new XMLHttpRequest(); } xmlObj.onreadystatechange = callBackFun; //指定回调函数 xmlObj.open("POST", "saveType.php", true); //指定提交方法和页面 xmlObj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;"); //指定发送数据库类型 xmlObj.send(urlData); //指定发送的数据 function callBackFun(){ //定义回调函数 if(xmlObj.readyState == 4 xmlObj.status == 200){ //如果服务器端返回内容并无错误发生 if(xmlObj.responseText == 'y'){ //判断保存是否成功,并给出提示 alert('类别添加成功!'); }else{ alert('类别添加失败!'); } } } } }
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'); ?>
