In this SharePoint tutorial, we will discuss how to create a custom announcement web part using Rest API in SharePoint Online or SharePoint 2013/2016.

Create SharePoint custom announcement web part

Here the announcements are stored inside a SharePoint custom list named as “Announcement” and it has a few columns like:

• Title
• Image Column

The list also has some data like below:

Now, create a SharePoint web part page and add a script editor web part into the web part page. Then paste the below code inside the script editor web part.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>

<script type="text/javascript">

    var ItemID = 0;
    var slidInd = "";
    var ids = [];
    var site = "https://pikasha12.sharepoint.com/sites/DLH/";

    $(document).ready(function () {

        var settings = {
            url: site + "_api/web/lists/getByTitle('Announcements')/items?$select=ID&$Orderby=Created desc&$top=5",
            type: "GET",
            headers: { "Accept": "application/json;odata=verbose" }
        }
        $.ajax(settings).done(
            function (data) {
                //script to build UI HERE
                slidInd = "";
                $.each(data.d.results, function (index, value) {
                    ItemID = value.ID;
                    ids.push(ItemID)
                });
                getImage();
            });
    });
    var htmls = [];
    function getImage() {
        $.each(ids, function (index, value) {
            var settings = {
                url: site + "_api/web/lists/getByTitle('Announcements')/items('" + value + "')/FieldValuesAsHtml?$select=Title,Image_x0020_Column",
                type: "GET",
                headers: { "Accept": "application/json;odata=verbose" }
            }

            $.ajax(settings)
                .done(function (response) {
                    var img = $(response.d.Image_x005f_x0020_x005f_Column);
                    slidInd = '';
                    slidInd = '<div class="media row"><div class="col-xs-4"><a href="https://pikasha12.sharepoint.com/sites/DLH/Lists/Announcements/DispForm.aspx?ID=' + value + '" class="pull-left"><img class="media-object" src="' + img[0].innerHTML + '"alt="amazing" height="100" width="100"></a></div><div class="col-xs-8"><h4 class="media-heading">' + response.d.Title + '</h4></div></div>';
                    $(".annoucement-items").append(slidInd);                  

                })
                .error(function () {

                });

            htmls.push(slidInd);

        });
    }
</script>

<style>
    .media {
        /* border: 1px solid #0797c2; */
        box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
        background: #790707;
        color: white;
        /* font-size: 16px; */
    }

        .media h4 {
            font-size: 14px;
        }
.ms-rtestate-field h4, h4.ms-rteElement-H4 {
    line-height: 1.6;
    color: #dedede;
}
        .media img:hover {
