值得注意的

当传入是Json类型的时候要var user = eval(result.d);

当传入是字符串的时候要用eval("exception = "+result.responseText);

复制代码 代码如下:

$.ajax

(

{

type: "POST",

contentType: "application/json",

url: serviceURL+"/UserLogin",

data: "{UserLoginID:'"+$('#txtLoginID').val()+"',UserLoginPW:'"+$('#txtLoginPW').val()+"'}",

dataType: 'json',

success: function(result)

{

var user = eval(result.d);

//eval("user="+result.d);

location.href = "Welcome.aspx?userID="+user.UserID

},

error: function(result, status)

{

if(status == 'timeout')

{

alert("The request timed out, please resubmit");

}

else

{

eval("exception = "+result.responseText);

//var exception = eval(result.responseText);

alert(exception.Message);

}

}

}

);
