如何从JavaScript中的URL获取JSON?

javascript

此URL返回JSON:

{
  query: {
    count: 1,
    created: "2015-12-09T17:12:09Z",
    lang: "en-US",
    diagnostics: {},
    ...
  }
}

我尝试了一下,但没有成功:

responseObj = readJsonFromUrl('http://query.yahooapis.com/v1/publ...');
var count = responseObj.query.count;

console.log(count) // should be 1

如何从该URL的JSON响应中获取JavaScript对象?

您可以使用jQuery .getJSON()函数:

$.getJSON('http://query.yahooapis.com/v1/public/yql?q=select%20%2a%20from%20yahoo.finance.quotes%20WHERE%20symbol%3D%27WRC%27&format=json&diagnostics=true&env=store://datatables.org/alltableswithkeys&callback', function(data) {
    //data is the JSON string
});
