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();}

var blogCtx  = new SP.ClientContext('/blog');var commentsList = blogCtx.get_web().get_lists().getByTitle('Comments');var createItem = new SP.ListItemCreationInformation();var newComment = commentsList.addItem(createItem);var commentBody = "Test comments from parent site";newComment.set_item('Title',SP.ScriptHelpers.removeHtmlAndTrimStringWithEllipsis(STSHtmlEncode(commentBody),30));newComment.set_item('Body',commentBody);newComment.set_item('PostTitle',1);newComment.update();blogCtx.executeQueryAsync(function () {        alert('comment added successed');    }, function (sender, args) {                       alert('comment added failed' + args);    }         );
