验证/清除JSON数据(Validate/Scrub JSON Data)

我正在进行Web服务调用并接收JSON格式的响应。 收到回复后，我想在页面中显示数据。 在我在页面上显示这些数据之前，我需要执行检查以确保定义了某些元素，如果没有给它们默认值（例如下面的例子）。

var scoreSummary = JSON.parse(response).summary; var gameStatus = scoreSummary.gameStatus ? scoreSummary.gameStatus : 'pre'; var homeRanking = scoreSummary.homeRank ? scoreSummary.homeRank : ''; var awayRanking = scoreSummary.awayRank ? scoreSummary.awayRank : ''

现在我有几个页面，我可以调用这个相同的Web服务，我不想复制所有检查，并设置默认值。 有没有办法可以集中这些检查，以便我只将它们放在一个地方，而不是分散在几个页面中，每个页面都进行相同的服务调用？

谢谢

I am making a web service call and receiving a JSON formatted response. After I receive the response, I would like to display the data in a page. Before I display this data on the page I need to perform checks to make sure that certain elements are defined, and if not give them default values (example below).

var scoreSummary = JSON.parse(response).summary; var gameStatus = scoreSummary.gameStatus ? scoreSummary.gameStatus : 'pre'; var homeRanking = scoreSummary.homeRank ? scoreSummary.homeRank : ''; var awayRanking = scoreSummary.awayRank ? scoreSummary.awayRank : ''

Now I have several pages where I can call this same web service and I do not want to duplicate all the checks, and setting of default values. Is there a way that I can centralize these checks so that I only have them in one place instead of scattered throughout several pages that each make the same service call?

Thanks

就像一个函数调用？

function setDefaultValues(jsonResponse) { var scoreSummary = JSON.parse(jsonResponse).summary; scoreSummary.gameStatus = scoreSummary.gameStatus || 'pre'; scoreSummary.homeRank = scoreSummary.homeRank || ''; scoreSummary.awayRank = scoreSummary.awayRank || ''; return scoreSummary; }

Like, a function call?

function setDefaultValues(jsonResponse) { var scoreSummary = JSON.parse(jsonResponse).summary; scoreSummary.gameStatus = scoreSummary.gameStatus || 'pre'; scoreSummary.homeRank = scoreSummary.homeRank || ''; scoreSummary.awayRank = scoreSummary.awayRank || ''; return scoreSummary; }
