微信浏览器中使用mui.ajax报timeout错误

    mui.ajax("http://api.map.baidu.com/geocoder/v2/",{  
        data:{  
            location:p.coords.latitude+","+p.coords.longitude,  
            output:"json",  
            ak:"EqfksL3lAG32G9BI94EcG41GQknG1x5K"  
        },  
        dataType:'json',  
        type:'get',  
        timeout:3000,  
        success:function(data){  
            data = JSON.stringify(data);  
            alert(data);  
            data = eval("("+data+")");  
            var c1=data.result.addressComponent.province;  
            var c2=data.result.addressComponent.city;  
            var c3=data.result.addressComponent.district;  
            document.getElementById("area").value=c1+" "+c2+" "+c3;  
        },  
        error:function(xhr,type,errorThrown){  
            mui.alert(type);  
        }  
    });
