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;
}
</script>

<body>
<a href="#" onclick="funphp('x');">x</a>
<a href="#" onclick="funphp('y');">y</a>
<a href="#" onclick="aaa('z');">z</a>
<p id="php100"></p>
</body>
</html>
------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
