jquery - 如何解析 tumblr JSON 提要

Question

我需要从此 JSON feed 获取常规标题和常规正文。我尝试了各种方法但收效甚微。大家有解决办法吗？

这不是 JSON，这是对 JSONP 的奇怪看法。

如果添加 <script />带有 src 的标签设置为http://clintonbeattie.tumblr.com/bio/json ，全局变量tumblr_api_read将指向一个带有响应信息的对象；

var tumblr_api_read = {
    "tumblelog": {
        "title": "First Title",
        "description": "",
        "name": "clintonbeattie",
        "timezone": "US\/Eastern",
        "cname": false,
        "feeds": []
    },
    "posts": [{
        "id": null,
        "url": "",
        "url-with-slug": "",
        "type": "regular",
        "date-gmt": " GMT",
        "date": "Wed, 31 Dec 1969 19:00:00",
        "bookmarklet": null,
        "mobile": null,
        "feed-item": "",
        "from-feed-id": 0,
        "unix-timestamp": 1333622193,
        "format": "html",
        "reblog-key": "TmN3ujDJ",
        "slug": "",
        "regular-title": "",
        "regular-body": ""
    }]
};

因此做这样的事情；

<script src="http://clintonbeattie.tumblr.com/bio/json"></script>
<script>
    // Use tumblr_api_read.

    alert(tumblr_api_read.tumblelog.title); // Shows "First Title"

    for (var i=0;i<tumblr_api_read.posts.length;i++) {
        var thisPost = tumblr_api_read.posts[i];

        alert("This post was created at " + thisPost.date);
    }
</script>
