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!'); } } } } }
