使用Jquery从JSON格式提取数据

问题描述

我有这样的URL，这是一个js文件示例，例如此链接 http://www.mysite. com/json.js 并且该链接将放入json格式的值，如下所示:

I have url like this which is a js file example like this link http://www.mysite.com/json.jsand that link will out put a json formatted values like below:

{
"note":null,
"attributes":null,
"total_price":9980,
"total_weight":0,
"item_count":4,
"items":[{
  "id":214597138,
  "title":"Acai +",
  "price":2495,
  "line_price":9980,
  "quantity":4,
  "sku":"",
  "grams":0,
  "vendor":"Delta Labs",
  "variant_id":214597138,
  "url":"/products/acai",
  "image":"http://cdn.shopify.com/s/files/1/0156/4994/products/acai_bottle.png?385",
  "handle":"acai",
  "requires_shipping":true
}],
"requires_shipping":true}

现在我想抓住那个链接，然后在我的jquery上，我将如何在json输出中使用该链接以获取诸如标题，URL，价格，sku等之类的值?

now i wanted to grab that link, then on my jquery how am i going to use that link with json output in order to get the values like the title, url, price, sku, and etc?

我在Google上搜索了是否有一些可以处理此问题的函数，然后我找到了jQuery.getJSON，但是我不太了解，或者它是否适用于我要完成的工作?

i searched on google if there are some functions that can handle this and i found jQuery.getJSON, but i don't really understand that much or is it applicable to my to what i am trying to accomplish?

顺便说一句， http://www.mysite.com/json.js ，它的json值是动态的，因此它是我想要抓取的链接，并输出json内容

By the way, http://www.mysite.com/json.js, its json value is dynamic, therefore it is the link i wanted to grab, and output the json content

推荐答案

例如，在ajax请求中，这就是我的方法.

Here is how I would do it, in an ajax request for example.

$.get('http://www.mysite.com/json.js', function(result) {
   var json = $.parseJSON(result);
   alert(json.title); //Do whatever you want here
});
