在wcf服务中，我在响应中得到json响应，它具有更多元素，但我需要获取单个元素的值.怎么办?
请帮帮我..


我在该服务响应中使用了一个wcf服务，我将格式设置为Json而不是xml，结果我得到了

推荐答案

您可以使用JQUERY提取所需的元素.而不是从头开始编写示例，请参阅此页面，那里有一个示例，该示例从twitter tweet JSON响应中提取元素.

您将看到tweet被传递给回调函数，并且使用tweet.theItem

You could use JQUERY to extract the elements you want. Rather than go and write an example from scratch, refer to this page, where there is an example of extracting the elements from a twitter tweet JSON response.

You will see the tweet, is passed to a callback function and the element is extracted using tweet.theItem
