Open your SharePoint site collection, from the settings icon, click on Site Settings. Then in the Site Settings page, click on Site content types under “Web Designer Galleries”.

Then I have created another site column known as “Company Branches”. Now here we will try to add this site column to the content type by using the JavaScript object model.

Add Site Column to Content Type using JavaScript Object Model

Below is the JavaScript code to add an existing site column to content type using JavaScript Object Model in SharePoint Online or SharePoint 2013/2016.

Just create a web part page, and then edit that web part page and add a script editor web part.

Insert the below JavaScript code to the script editor web part. Save the page.

<script language="javascript" type="text/javascript">
function AddContentType() {
var ctx = new SP.ClientContext.get_current();
var field = ctx.get_site().get_rootWeb().get_fields() .getByInternalNameOrTitle("Company_x0020_Branches");
var ctype = ctx.get_site().get_rootWeb().get_contentTypes() .getByI("0x0100BD927BBDD704954CB6FEA329CB809491″);
var createInfo = new SP.FieldLinkCreationInformation();
var fieldLink = ctype.get_fieldLinks().add(createInfo);
ctype.update (true);
ctx.executeQueryAsync(success, failure);

function success() {

function failure() {

<button type="button" onclick="AddContentType();">Add Site Column to Content Type</button>

Here you need to give the Site column’s internal name. And The GUID of the content type.

Click on the button, it will add the site column to the content type.

Now if you will open the content type, you will be able to see the site column added to the content type.
