没看到有任何地方分配了事件给mousestatus函数，也就是说没有任何地方能够调用这个函数。
试试把事件分配的代码放到函数外面：
function mousestatus(e){
if(!e)
e=window.event;
btn=e.button;
whichone=(btn<2)? "Left" : "Right";
message=e.type+":"+"+whichone+"\n";
document.form1.info.value+=message;
}
obj=document.getElementById("testlink");
obj.onmousedown=mousestatus;
obj.onmouseup=mousestatus;
obj.onclick=mousestatus;
obj.ondblclick=mousestatus;

message=e.type+":"+"+whichone+"\n";
这里有语法错误。
message=e.type+":"+whichone+"\n";
这样？
