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!');
        }
      }
    }
  }
