jQuery的JSON方法有问题-TroublewithjQuery'sJSONMethod

Presumably the url is in a different domain. You'll need to use JSONP and add &jsOncallback=? to your query. I assume that the audioscrobbler API supports this.

据推测,该网址位于不同的域中。你需要使用JSONP并添加&jsOncallback=?对你的查询。我假设audioscrobbler API支持这一点。

Visiting that URL gives me a file that says, "Invalid API key - You must be granted a valid key by last.fm"

访问该URL会给我一个文件,上面写着“无效的API密钥 - 您必须通过last.fm授予有效密钥”

According to that link http://www.ibm.com/developerworks/library/wa-aj-jsonp1/, you have to add an "&callback=?" at the end of your URL (reason for this, is that jQuery automaticly uses JSONP to bypass AJAX Cross Domain policy when using $.getJSON).

根据http://www.ibm.com/developerworks/library/wa-aj-jsonp1/链接,您必须添加“&callback =?”在URL的末尾(原因是,jQuery在使用$ .getJSON时自动使用JSONP绕过AJAX跨域策略)。

So, if you pass below url to getJSON: http://ws.audioscrobbler.com/2.0/?method=user.getweeklyartistchart&user=ElicitBelief&api_key=25135a535781328243f9e31968abc14&format=json&callback=? you'll get JSON respoonse with : "Invalid API key - You must be granted a valid key by last.fm"

所以,如果您通过以下网址获取getJSON:http://ws.audioscrobbler.com/2.0/?method = user.ekweeklyartistchart&user = EnglishBelief&api_key = 25135a535781328243f9e31968abc14&format = json&callback =?您将获得JSON respoonse:“无效的API密钥 - 您必须通过last.fm授予您有效的密钥”

Check this for demo: JSBin (page is empty, but look at requests in Firebug console)

检查这个以获得演示:JSBin(页面为空,但在Firebug控制台中查看请求)
