原生ajax get提交数据,使用原生js封装ajax,post、get请求
//五个参数 type:GET/POST, url:请求地址，data:请求的数据，success:成功的回调函数
// failed:失败的回调函数
function Ajax(type,url,data,success,failed){
//创建ajax对象
var xhr = null,
random = Math.random(),
type = type.toUpperCase();
if(window.XMLHttpRequest){
xhr = new XMLHttpRequest();
}else{
xhr = new ActiveXObject(Microsoft.XMLHTTP);
}
if(typeof data == object){
var str = ;
for(var key in data){
str += key+=+data[key]+&;
}
console.log(str);//name=zlz&sex=female&
data = str.replace(/&$/,);
console.log(data);//name=zlz&sex=female
}
if(type == GET){
if(data){
xhr.open(GET,url + ? + data,true);
}else{
xhr.open(GET,url + ?t= +random,true);
}
xhr.send();
}else if(type == POST){
xhr.open(POST,url,true);
//如果需要像html表单那样 post数据，请使用 setRequestHeader() 来添加http头
xhr.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xhr.send(data);
}
//处理返回数据
xhr.onreadystatechange = function (){
if(xhr.readyState == 4){
if(xhr.status == 200){
success(xhr.responseText);
}else{
if(failed){
failed(xhr.status);
}
}
}
}
}
//测试调用
var sendData = {name:zlz,sex:female,age:18}
Ajax(post,test1.html,sendData,function(data){
console.log(data);
},function(error){
console.log(error+error);
})
