blogger:在博客里显示最新文章的小插件－－ViewTab Widget

代码已经更新，已经可以支持中文了。^_^
它的风格和雅虎的差不多。这次更新多了几项内容，不仅可以按标签分类来显示最新的文章，而且加了显示全部的最新文章和最新的评论。功能算是很强大了，以前的那些插件可以都不要了。

• 第一步：

在 ]]></b:skin> 后面或者在</head>前加入下面的代码
<script type='text/javascript'>
// Developed by Sisea - All rights reserved 2007
// This credit must be included in all your derived usages.

// "cb" is intended to be a common library, where different widgets would
// utitlize the shared operations such as getTitle, getLink, etc. from a json object.
var cb = {

// search function requires these parameters:
// 1. query: a blogger address, such as "sisea.blogspot.com",
// 2. type: type of return data, either "comments" or "posts",
// 3. start: the start-index parameter (where to start extracting data)
// 4. increment: the number of elements the json will get back. (the smaller value, the faster time to travel back)
// 5. func: the returned function the json object will feed.

search: function(query, type, start, increment, func) {
var script = document.createElement('script');
script.setAttribute('src', 'http://' + query + '/feeds/' + type + '/default?alt=json-in-script&start-index='
+ start + '&max-results=' + increment + '&callback=' + func + '&orderby=published');
script.setAttribute('type', 'text/javascript');
document.documentElement.firstChild.appendChild(script);
},

// searchLabel function return a result of posts w/ a label query
// it requires these parameters:
// 1. query: a blogger address, such as "sisea.blogspot.com",
// 2. an array of labels
// 3. func: the returned function the json object will feed.
searchLabel: function(query, label, func) {
var script = document.createElement('script');
script.setAttribute('src', 'http://' + query + '/feeds/posts/default/-/' + encodeURIComponent(label) +
'?alt=json-in-script&callback=' + func + '&orderby=published');
script.setAttribute('type', 'text/javascript');
document.documentElement.firstChild.appendChild(script);
},

// getTotalResults needs the json object, and it'll return the total number of comments (or posts) of the blog.
getTotalResults: function(json) {
return json.feed.openSearch$totalResults.$t;
},

// getStartIndex gets the start index of a search inside an json object.
getStartIndex: function(json) {
return json.feed.openSearch$startIndex.$t;
},

// getLink return a href link if "name" matches the content inside "a" tags) of the link
getLink: function(entry, name) {
var alturl;

for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == name)
alturl = entry.link[k].href;
}
return alturl;
},

// getTitle gets the title of the title of an entry of a json object.
getTitle: function(entry) {
return entry.title.$t;
},

// getContent gets the content inside an entry of a json object.
getContent: function(entry) {
return entry.content.$t;
},

// getCommentAuthor: gets the commenter name inside an entry of a json object.
getCommentAuthor: function(entry) {
return entry.author[0].name.$t;
},

// Given a json label search, this function return the decoded label.
getLabelFromURL: function(json) {
for (var l = 0; l < json.feed.link.length; l++) {
if (json.feed.link[l].rel == 'alternate') {
var raw = json.feed.link[l].href;
// The next two lines are borrowed from Ramani's Neo Template
// code. Thanks Ramani!
var label = raw.substr(raw.lastIndexOf('/')+1);
return decodeURIComponent(label);
}
}
},
txt : function (s) {
return s + " Widget by <a href='http://sisea.blogspot.com/" + "'>sisea</a>";
}
};
</script>

• 第二步：

紧跟其后加入或者在</head>之前加入下面代码
<link href='http://yui.yahooapis.com/2.2.2/build/tabview/assets/tabview.css' rel='stylesheet' type='text/css'/>

<script src='http://yui.yahooapis.com/2.2.2/build/yahoo-dom-event/
yahoo-dom-event.js' type='text/javascript'/>
<script src='http://yui.yahooapis.com/2.2.2/build/element/
element-beta-min.js' type='text/javascript'/>
<script src='http://yui.yahooapis.com/2.2.2/build/tabview/tabview-min.js' type='text/javascript'/>



<style type='text/css'>

.yui-content {
padding:1em; /* pad content container */
}

.yui-navset .yui-content {
border:1px solid #ccc;
}
.yui-navset .yui-nav .selected a, .yui-navset .yui-nav a:hover {
background-color:#fff;
}

.yui-navset .yui-nav li a {
background:#e5e5e5 url(http://developer.yahoo.com/yui/examples/tabview/img/
round_4px_trans_gray.gif) no-repeat;
}
.yui-navset .yui-nav li a em {
background:transparent url(http://developer.yahoo.com/yui/examples/tabview/img/
round_4px_trans_gray.gif) no-repeat top right;
padding:0.5em;
}

/* top oriented */

.yui-navset-top .yui-nav { margin-bottom:-1px; } /* for overlap, based on content border-width */
.yui-navset-top .yui-nav li a {
border-bottom:1px solid #ccc;
}

.yui-navset-top .yui-nav .selected a { border-bottom:0; }
.yui-navset-top .yui-nav .selected a em { padding-bottom:0.6em; } /* adjust height */
</style>

• 第三步：

在任意"b:widget"之间加入下面的代码。
<b:widget id='HTML102' locked='false' title='MultiTab Widget' type='HTML'>
<b:includable id='main'>
<div class='widget-content'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != ""'>
<h2 class='title'
></h2>
</b:if>
<div id='doc'>
<div>
<h2>Sisea's Place</h2>
<div class='yui-navset' id='multiTab1'/>
</div>

<!--
<div>
<h2>Hackosphere</h2>
<div class='yui-navset' id='multiTab2'/>
</div>
-->

</div>
<div id='103'/>
</div>

<script type='text/javascript'>
// Developed by Sisea - All rights reserved 2007
// This credit must be included in all your derived usages.
var p1 = document.createElement('h6');
document.getElementById('103').appendChild(p1);
p1.innerHTML = cb.txt('TabView');

function listOneTab(json, tabView, title, act) {
var label = '';
var text = '';
var nPost = 10;

if (title == "")
label += cb.getLabelFromURL(json);
else
label += title;

text += "<div id='" + label + "'><ul>";

var numberPost = (json.feed.entry.length <= nPost) ?
json.feed.entry.length : nPost;

for (var i = 0; i < numberPost; i++) {
var entry = json.feed.entry[i];
text += "<li>" + "<a href='" + cb.getLink(entry, "alternate")
+ "'>" + cb.getTitle(entry) + "</li>";
}

text += '</ul></div>';

tabView.addTab( new YAHOO.widget.Tab({
label: label,
content: text,
active : act
}));


}

var blog1 = "sisea.blogspot.com";
var tabView1 = new YAHOO.widget.TabView('multiTab1');
var labels1 = [ "google fans","图片和壁纸", "影视音乐"];
function listTab1(json) {
listOneTab(json, tabView1, "", false);
}
function listLatestPostsTab1(json) {
listOneTab(json, tabView1, "Latest Posts", true);
}
function listLatestCommentsTab1(json) {
listOneTab(json, tabView1, "Latest Comments", false);
}

// Activating calls!

// Latest Posts
cb.search( blog1, "posts", 1, 25, 'listLatestPostsTab1');

// Latest Comments
cb.search( blog1, "comments", 1, 25, 'listLatestCommentsTab1');

// Preferred Labels
for (var i=0; i < labels1.length; i++)
if (labels1[i]) cb.searchLabel(blog1, labels1[i], 'listTab1');

/*
var blog2 = "hackosphere.blogspot.com";
var tabView2 = new YAHOO.widget.TabView('multiTab2');
var labels2 = ['Neo','Widgets', "Blogger Power"];
function listTab2(json) {
listOneTab(json, tabView2, "", false);
}
function listLatestPostsTab2(json) {
listOneTab(json, tabView2, "Latest Posts", true);
}
function listLatestCommentsTab2(json) {
listOneTab(json, tabView2, "Latest Comments", false);
}
// Activating calls!
// Latest Posts
cb.search( blog2, "posts", 1, 25, 'listLatestPostsTab2');

// Latest Comments
cb.search( blog2, "comments", 1, 25, 'listLatestCommentsTab2');

// Preferred Labels
for (var i=0; i < labels2.length; i++)
if (labels2[i]) cb.searchLabel("hackosphere.blogspot.com", labels2[i], 'listTab2');

*/
