从URL解析JSON [英] Parse JSON from URL

问题描述

我正在建立一个网站，并且使用一个返回JSON响应的URL，例如:

I am building a web site and I use a url which returns a JSON response, like:

{name:mark; status:ok}

我想在HTML页面中仅使用JavaScript或jQuery来获取名称.

I would like to obtain the name, using only JavaScript or jQuery in my HTML page.

有人可以帮我做到这一点吗?

Can somebody help me to do this?

推荐答案

看看jQuery的 方法，这对您来说真的很容易.

Have a look at jQuery's .getJSON() method, which will make it really easy for you.

$.getJSON('yourURL.php', function(data) {
  alert(data.name);
});

如果您需要更大的灵活性，则应该看看 .ajax() . .getJSON()实际上只是.ajax()方法的简写形式，适合于进行简单的请求以获取JSON.使用.ajax()，您将有更多选择-例如指定错误处理程序等等.

If you need more flexibility you should have a look at .ajax() instead. .getJSON() is really just a short hand for the .ajax() method, suitable for making simple requests to fetch JSON. With .ajax() you will have a lot of more options - specifying an error handler for instance, and much more.
