Creating Content Type And Field Using JSOM

In this blog we are going to discuss about how to create list content type and its field under site content type using JSOM. Content type is the set of columns which we can reuse in all lists and libraries in a site.
 
I am providing the steps below to create content type and its fields.
 
Step 1
 
First get the Current Context.
 
Step 2
 
We have to get the content type collection and then have to create a new content type by using "SP.ContentTypeCreationInformation". Here we must set the new content type name, description, ID, and group.
 
Step 3
 
Declare a function "createSfield()" for creating site field. Here I have created a text field having name "EmployeeName" and groupname "Employee Data" by using "addFieldAsXml". And called this function inside the executequery() of fuction "createCType()".
 
Step 4
 
Then we have added the created site field to the new content type. For this first we get the content type by its id then add the field using "SP.FieldLinkCreationInformation()".

After running the code, we can check the content type in the Site content type option under site setting. Then by clicking on the content type title (‘My Content Type’), we can check the field of content type. Please refer to the the below image for better reference.
