SharePoint 2013 Hosting – HostForLIFE.eu :: Custom Like And Comment Functionality For SharePoint Online Custom Pages

Today we will see how to add custom like and comment functionality in SharePoint custom pages. For that I have developed one common web part/txt file using JQuery and REST api. Currently SharePoint is providing likes and rating functionality for the list items. I tried to use this but this was not required so I tried to develop this custom functionality for SharePoint online pages.

You need to just add one content editor web part and add the below code into that web part. Below are the overall steps.Step 1
Create custom list in SharePoint having name “LikesList” to store all the likes given by the user. Add the below columns into it,

column name : LikeBy type : Person or Group
column name : CommentID type : Number
column name : PageURL type : Single line of text

Step 2
Create custom list in SharePoint having the name “CommentsList” to store all the comments added by user. Add the below columns into it,

column name : ParentCommentID type : Number
column name : CommentText type : Multiple lines of text
column name : PageURL type : Single line of text
column name : CommentBy type : Person or Group

Step 3
Now create one text file and add the below code into it and save that file.

<div style="width: 70%;background-color: white;color: black; border-radius: 5px; padding:10px;">  
    <table style="width:100%">  
        <tbody>  
            <tr>  
                <td style="text-align: right;">  
                    <span id="lblPageComments">0 Comments | </span>  
                    <span id="spLikes" title="" class="LikeClass">  
                        <img id="imgLike" src="../_layouts/15/images/LikeFull.11x11x32.png?rev=23">  
                        <span id="lblPageLikes">0</span>  
                    </span>  
                    <a id="lnkBtnPageLike" class="links">Like</a>  
                    <span id="LikeID" style="display:none;"></span>     </td>  
            </tr>  
            <tr>  
                <td style="padding-left: 5px;">  
                    <h3>Comment : </h3>  
                </td>  
            </tr>  
            <tr>  
                <td style="padding: 25px;">  
                    <textarea name="txtComments" rows="3" cols="20" id="txtComments" placeholder="Comment..." style="width:95%;"></textarea><br><br>
