本文讲述如何用JavaScript 操作  SharePoint 2013 中blog相关列表。

包括：发贴，读取贴子列表，Like/Unlike 帖子，回复帖子，读取某个帖子的所有回贴。

发贴： 

  var blogCtx  = new SP.ClientContext('/blog');         
        var postsList = blogCtx.get_web().get_lists().getByTitle('Posts');         
        var createItem = new SP.ListItemCreationInformation();      
       var newPost = postsList.addItem(createItem);
       newPost.set_item('Title', 'Test submit post from parent site/web'); // Post title
       newPost.set_item('Body', 'Test post body from parent site/web'); // Post body
      newPost.set_item('PostCategory', 1); // category item id
      newPost.set_item('PublishedDate', new Date()); // publish date
       newPost.update();
       
	blogCtx.executeQueryAsync(
	function () {
        alert('post added successed');
            }, function (sender, args) {
                       alert('Post added failed' + args);
            }
         );

读取贴子列表： 

	var blogCtx = new SP.ClientContext('/blog');
	var oWebsite = blogCtx.get_web();
	var oList = oWebsite.get_lists().getByTitle("Posts");
	var camlQuery = new SP.CamlQuery();
	camlQuery.set_viewXml('<View><Query><Where><IsNotNull><FieldRef Name=\'Title\' /></IsNotNull></Where></Query>' + '<RowLimit>10</RowLimit></View>');
	var collListItem = oList.getItems(camlQuery);
	blogCtx.load(collListItem, 'Include(Id,Title,Body,Created,Author,NumComments,LikesCount,LikedBy)');
	blogCtx.executeQueryAsync(successHandler, errorHandler);
	
	function successHandler() {
	    var listItemEnumerator = collListItem.getEnumerator();
	
	    var listItemInfo = "";
	    while (listItemEnumerator.moveNext()) {
	        var oListItem = listItemEnumerator.get_current();
	        listItemInfo += "ID: " + oListItem.get_id() + "<br/>" + "Title: "
	            + oListItem.get_item("Title") + "<br/>" + "Body: "
	            + oListItem.get_item("Body") + "<br/>" +
	            "datetime:" + oListItem.get_item("Created") + "<br/>" +
	            "Author:" + oListItem.get_item("Author") +
	            "NumComments:" + oListItem.get_item("NumComments") +
	            "LikesCount:" + oListItem.get_item("LikesCount") +
	             "LikedBy:" + oListItem.get_item("LikedBy");
	    }
	
	    alert(listItemInfo);
	}
	
	function errorHandler() {
	    resultpanel.innerHTML = "Request failed: " + arguments[1].get_message();
	}

Like/Unlike 帖子，请参考http://blog.csdn.net/abrahamcheng/article/details/9791433

		newComment.set_item('Body',commentBody);
		newComment.set_item('PostTitle',1);
		newComment.update();
		blogCtx.executeQueryAsync(
		function () {
		        alert('comment added successed');
