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!');
- }
- }
- }
- }
- }
