我有一个blogger.com博客,我已经设法创建了一个从博客中获取数据的脚本 - 我不太擅长js / json,所以我对此有点盲目; - )
我喜欢2 DIVS中的输出,这些输出对于帖子ID和内容是唯一的:
这是剧本:
<html>
<head>
<title>Test</title>
</head>
<body>
<script type="text/javascript">
function posts(json) {
// Get five recent posts
for (var i = 0; i < 2; i++)
{
var posturl;
// Get rel=alternate for truly post url
for (var j=0; j < json.feed.entry[i].link.length; j++)
{
if (json.feed.entry[i].link[j].rel == 'alternate')
{
posturl = json.feed.entry[i].link[j].href;
break;
}
}
// if the Blogger-feed is set to FULL, then the content is in the content-field
// if the Blogger-feed is set to SHORT, then the content is in the summary-field
if ("content" in json.feed.entry[i]) {
var postcontent = json.feed.entry[i].content.$t;}
else
if ("summary" in json.feed.entry[i]) {
var postcontent = json.feed.entry[i].summary.$t;}
else var postcontent = "";
// strip off all html-tags
var re = /<\S[^>]*>/g;
postcontent = postcontent.replace(re, "");
// reduce postcontent to 200 characters
if (postcontent.length > 200) postcontent = postcontent.substring(0,200);
// Get posts title
document.write("Post Id = "+json.feed.entry[i].id.$t);
document.write('<br/>');
document.write("Post content = "+postcontent);
document.write('<br/><br/>');
}
}
</script>
<script src="http://ironheartuk123.blogspot.com/feeds/posts/default?alt=json-in-script&callback=posts"></script>
</body>
</html>
当我将页面加载到浏览器中时,我在屏幕上显示:
Post Id = tag:blogger.com,1999:blog-5655651846573938667.post-5882120439717312684
Post content = Test post 2
Post Id = tag:blogger.com,1999:blog-5655651846573938667.post-8794205203420774123
Post content = Test post 1
这就是我更喜欢的输出!
<div id="5882120439717312684">Test post 2</div>
<div id="8794205203420774123">Test post 1</div>
完成该步骤后,我将能够将Div移动到页面上的正确位置。我认为这很容易; - )
任何帮助都非常感谢!!

使用jQuery:
var re = /post-\d+/;
var postId = re.exec(json.feed.entry[i].id.$t);
$("#" + postId[0]).html(postcontent);
