超级奇怪jquery ajax问题，IE8-以下时正常时不正常。FF,CH下正常。


$.ajax({url:"../ajax.aspx",
type:"POST",
data:{"id":id,"type":"getShoptypeVal"},
dataType:"html",
timeout:20000,
cache: false,
error:function(result){alert("readyState: "+result.readyState+"\nstatus: "+result.status);
    alert("responseText: "+result.responseText);},
success:function(result){
if(result.length > 0)
{
//do something...
}
}
});
