用xmlhttp提交 a=new ActiveXObject("Microsoft.XMLHTTP")
a.open("POST","aa.asp",false);
a.setRequestHeader("content-type","application/x-www-form-urlencoded");
a.send("name=zhangsan")
a.open("POST","aa.asp",false);
a.setRequestHeader("content-type","application/x-www-form-urlencoded");
a.send("name=zhangsan")
1.用xmlhttp对象提交是否与form提交没有差别,目标页面可以是htm,cgi,php,asp?
2.xmlhttp方式提交的效率如何,与form方式相比。
