本文實例講述了PHP+Ajax實現的博客文章添加類別功能。分享給大家供大家參考,具體如下:
一. 代碼
fun.js
function saveType(typename, username){
if(typename==''){ //判斷博客類別是否為空
alert('請輸入類別名稱!');
}else if(username==''){ //判斷用戶名是否為空
alert('請輸入用戶名!');
}else{
var xmlObj; //定義XMLHttpRequest對象
var urlData = "typename="+typename+"username="+username; //指定要發送的數據
if(window.ActiveXObject){ //判斷瀏覽器是否支持ActiveXObject組件,如支持則通過ActiveXObject方式創建XMLHttpRequest對象
xmlObj = new ActiveXObject("Microsoft.XMLHTTP");
}else if(window.XMLHttpRequest){ //如果瀏覽器不支持ActiveXObject組件,則使用XMLHttpRequest組件創建XMLHttpRequest對象
xmlObj = new XMLHttpRequest();
}
xmlObj.onreadystatechange = callBackFun; //指定回調函數
xmlObj.open("POST", "saveType.php", true); //指定提交方法和頁面
xmlObj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;"); //指定發送數據庫類型
xmlObj.send(urlData); //指定發送的數據
function callBackFun(){ //定義回調函數
if(xmlObj.readyState == 4 xmlObj.status == 200){ //如果服務器端返回內容并無錯誤發生
if(xmlObj.responseText == 'y'){ //判斷保存是否成功,并給出提示
alert('類別添加成功!');
}else{
alert('類別添加失敗!');
}
}
}
}
}
