How to parse JSONP data returned from remote server
提问by patricksweeney
I am trying to grab some data via JSONP. Using Firebug, I am able to see the data properly being returned, but I am having a hard time thinking how I have to parse it. The data return is really a nested array correct? someFunctionis the name of the callback function. This is how the data looks:
我正在尝试通过 JSONP 获取一些数据。使用 Firebug，我能够看到正确返回的数据，但我很难思考如何解析它。数据返回真的是嵌套数组正确吗？someFunction是回调函数的名称。这是数据的样子：
someFunction([
{
"title":"Sample Title",
"link":"http://example.com",
"description":"Sample Description",
"publisher":"Sample Publisher",
"creator":"Sample Author",
"date":"Thu, 19 Aug 2010 12:41:29 GMT",
"num_pages":10,
"num_results":"10"
},
]);
Just a little confused about how to properly parse and output.
只是对如何正确解析和输出有点困惑。

You don't have to parse the data. It is already a valid JavaScript object. For instance, to print the description property for the first object inside someFunction
您不必解析数据。它已经是一个有效的 JavaScript 对象。例如，打印 someFunction 中第一个对象的描述属性
function someFunction(result) {
alert(result[0].description); // alerts "Sample Description"
}

Write a function with the correct name and the correct arguments. The JS engine will do the parsing for you.
用正确的名称和正确的参数编写一个函数。JS 引擎会为你做解析。
function someFunction(data) {
// Now data is an Array, containing a single
// Object with 8 properties (title, link, etc)
}
