如何在Javascript中从URL获取JSON？ [英] How to get JSON from URL in Javascript?

问题描述

此URL 返回JSON：

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

我试过这个，但它不起作用：

I tried this, and it didn't work:

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

console.log(count) // should be 1

怎么能我从这个URL的JSON响应中获取了一个JavaScript对象？

How can I get a JavaScript object from this URL's JSON response?

推荐答案

你可以使用jQuery .getJSON（） 功能：

You can use jQuery .getJSON() function:

$.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
});

如果您不想使用jQuery，那么您应该看看纯JS解决方案的答案：< a href =https://stackoverflow.com/a/2499647/1361042> https://stackoverflow.com/a/2499647/1361042
