Sharepoint Retrieve Taxonomy term Store via Javascript

This blog would show you the retrieve term store, the term group, the term set and the term via JavaScript

1. First, you need understand Managed Metadata Service, it used for storing Metadata, and has the database in dependent, Then all the site collection can reuse the data, such as Site column (Metadata field), Metadata Navigation and search data. Here are its construct:

Managed Metadata Service, term Stores, term Groups, term sets-

2. Second, since you retrieve metadata via JS, so SharePoint need provide the relevant API, here is the JS file provided By SharePoint OOB File:

SP. Runtime.js, Sp.js, SP. Taxonomy.jsmust make sure load those JS before your call the API (only SharePoint provide the API).

3. Implement content in detail

NOTE:I get the default term store directly, in default, SharePoint don ' t set it, so you have to set in Admin Center, or T He code would encounter issues.

Here are the example to retrieve the metadata navigation and print out.

JavaScript source Code<script>_spbodyonloadfunctionnames.push (' start '); function Start () {var scriptbase = _sp    Pagecontextinfo.webserverrelativeurl + "/_layouts/15/"; $.getscript (Scriptbase + "SP.
