Get list of all content type associated with a list

Question

I am using client code using JQuery and rest API where I have a requirement to bind a drop down control with the content type names associated with a particular list.

I am working on SharePoint 2016 on-premise.

Any help on this would be highly appreciated

Answer 1

Try using below endpoint:

http://<sitecollection>/<site>/_api/web/lists/getbytitle('Display name of List')/contenttypes

OR

http://<sitecollection>/<site>/_api/web/lists(listid)/contenttypes

official documentation: SP.ContentTypeCollection object - REST resource endpoint.

Update:

Try using something like below to fetch the names of content type. This is like pseudo code for your reference. You can check the exact data you are getting from REST call by adding break-point inside success function:

$.ajax({
    url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/Lists/getbytitle('Display name of List')/contenttypes?$select=Name,Id",
    type: "GET",
    headers: {
        "Content-Type": "application/json;odata=verbose"
        "Accept": "application/json;odata=verbose"
    },
    success: function(data) {
        var optionsArray = [];
        if(data.d && data.d.results) {
            for(var i = 0; i < data.d.results.length; i++) {
                console.log(data.d.results[i].Name);
                // Push the content type name in array
                optionsArray.push(data.d.results[i].Name);
            }
        }
    },
    error: function(error) {
        console.log(error);
    }
});

Answer 2

With GET request you can get all the content types of your specified list

.../_api/web/lists(ID)/contenttypes

I recommend to use extension in your Browser Called SharePoint Insider, it will help you a lot to figure out the endpoints that will help you to build your REST request

Best regards.
