contentType:"application/json",
url: "WCFServices/UserRightValid.svc/LoginValid",
data:"{\"userName\":\""+$("#UserName").val()+"\",\"password\":\""+$("#Password").val()+"\"}",//这一句非常重要,如果你要调用的方法是没有参数的
processData:false,
dataType:"json",
success: function(data){
if(data)
{
alert("成功");
}
else
{
alert("用户名或者密码不正确!");
}
},
error:function(XMLHttpRequest, textStatus, errorThrown){
alert( "Error Occured!" );
