JQuery.ajax（）：使用WCF服务时出现参数数据问题

I'm using JQuery to consume a WCF Service. Actually this works fine:

我正在使用JQuery来使用WCF服务。实际上这很好用：

var para = ' { "Parameter" : { "ID" : "5", "Name" : "Peter" } }'
$.ajax({
   type: "POST",
   contentType: "application/json",
   data: para,
   url: url
   success: success
});

But I don't want to pass the data parameter as String and I think it should be possible to pass ist as array in any way. Like that:

但我不想将数据参数作为String传递，我认为应该可以以任何方式将ist作为数组传递。像那样：

var para = { "Parameter" : { "ID" : 5, "Name" : "Peter" } }

But when I try this I'm getting an error. What I'm doing wrong?

但是当我尝试这个时，我收到了一个错误。我做错了什么？

Thanks

谢谢

#1

var para = '{ "ID" : "5", "Name" : "Peter" }';
$.ajax({
   type: "POST",
   data: para,
   url: url
   success: success
});

If you format it like this you should be able to get the values as

如果你这样格式化，你应该能够得到值

$_POST will return array('ID' => '5', 'Name' => 'Peter');

but you can also access it by doing:

但你也可以通过这样做来访问它：

$_POST['ID'] and $_POST['Name']

Also you could make use of the jquery post function:

你也可以使用jquery post函数：

var para = '{ "ID" : "5", "Name" : "Peter" }';
$.post(
    url, 
    para
);

You can use JSON.stringify function from the json2.js. Then you ajax call will be

您可以使用json2.js中的JSON.stringify函数。然后你将ajax调用

var para = { Parameter : { ID :5, Name : "Peter" } };
$.ajax({
   type: "POST",
   contentType: "application/json",
   data: JSON.stringify(para),
   url: url
   success: success
});

The usage of manual conversion to the JSON string is not good because of possible spatial characterless in the string which must be escaped (see http://www.json.org/ for details).

手动转换为JSON字符串的用法并不好，因为字符串中可能存在空间无字符，必须进行转义（有关详细信息，请参阅http://www.json.org/）。
