AJAX在执行时readyState的状态总是为1 - Web 开发 / Ajax
新手,初学JS和ajax,照着学习视频上的代码写了然后组合了下,但是测的readyState的状态总是为1,不会改变,然后也就得不到服务器端的返回值,帮我看下代码有没有问题,顺便问问是不是php,apache配置也有可能造成这种情况

var ajax=null;
function funphp(url) {
request=createAjax();
request.onreadystatechangge = byphp();
request.open("GET","test2.php?id="+url+"&"+Math.random(),true);
request.send(null);
}
function byphp(){
if(request.readyState<4){
document.getElementById('php100').innerHTML='loading...';
}
if(request.readyState==4){
if(request.status==200){
var byphp100=request.reponseText;
document.getElementById('php100').innerHTML=byphp100;
}
else {document.getElementById('php100').innerHTML='load...';}
}
}
//z注释的是自己写的测试的
function aaa(id){
window.location.href='test2.php?id='+id;
}

------解决方案--------------------
request.onreadystatechangge = byphp();
应该改成
request.onreadystatechange = byphp;
byphp就是回调函数
onreadystatechangge 拼写错误
------解决方案--------------------onreadystatechangge
