Add Column To Site Content Type in SharePoint using JSOM

The example in this topic show how to use JSOM to Add Column To Site Content Type in SharePoint

You can use Content Editor or Script Editor web part on your site, put Html and JSOM (Java Script Object Model) code and that's it. You can perform any action supported by JSOM APIs

How to execute JSOM code in SharePoint?

Note: This is just a sample, you can go ahead with your implementation.
Open your Site. Create a webpart page.
Put a Content Editor Web part and a Script Editor Web part on it.

Webpart page content editor and scipt editor

I have added below Html in Content Editor webpart. You can replace MainFunction with your actual method name.
<button onclick="MainFunction();" type="button">Click me</button>
And below references in Script Editor Webpart. You can keep jQuery reference as per your need. ScriptFile.js is a JavaScript file where you can keep below function i.e. your actual logic.
<script src="https://code.jquery.com/jquery-2.2.4.js" type="text/javascript"></script>

<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>

<script type="text/javascript" src="/_layouts/15/sp.js"></script>

<script src="https://MyServer/sites/SiteCollection/style library/js/ScriptFile.js"></script>
Once you are done with setting your page, click on the button and your method should get executed.

var oSiteContentTypes, clientContext, oSiteColumn;
function AddSiteColumnToContentType() {
// You can optionally specify the Site URL here to get the context
// If you don't specify the URL, the method will get the context of the current site
// var clientContext = new SP.ClientContext("http://MyServer/sites/SiteCollection");
clientContext = new SP.ClientContext();
var oWeb = clientContext.get_web();
// Get Site Column object
oSiteColumn = oWeb.get_fields().getByInternalNameOrTitle('Column Name');
// Get Site Content Type object
oSiteContentTypes = oWeb.get_contentTypes();
// Load Site Column to Client Context
clientContext.load(oSiteColumn);
// Load Site Content Type to Client Context
clientContext.load(oSiteContentTypes);
// Execute the query to the server.
clientContext.executeQueryAsync(onQuerysuccess, onQueryfailed);
}
function onQuerysuccess() {
// Iterate through Enumerator
var oEnumerator = oSiteContentTypes.getEnumerator();
var oContentType;
// Counter variable to be used to break below loop
var counter = 0;
while (oEnumerator.moveNext())
{
// This line of codde is written to break the loop
if (counter == 1)
{
break;
}
oContentType = oEnumerator.get_current();
// Specify the Content Type Name here
if (oContentType.get_name() == "Content Type Name") {
counter += 1;
var newSiteCol = new SP.FieldLinkCreationInformation();
newSiteCol.set_field(oSiteColumn);
//Add Site Column to ContentType
oContentType.get_fieldLinks().add(newSiteCol);
oContentType.update(true);
//Load client context and execute batch
clientContext.load(oContentType);
clientContext.executeQueryAsync(onsuccess, onfailed);
}
}
}
function onQueryfailed(sender, args) {
console.log('Failed' + args.get_message() + '\n' + args.get_stackTrace());
}
function onsuccess() {
console.log("success");
}
function onfailed(sender, args) {
console.log('Creation Failed' + args.get_message() + '\n' + args.get_stackTrace());
}
