Add Enterprise Keyword Column In SharePoint List Using JSOM

My scenario is, I need to create Enterprise keyword column in SharePoint host web list using SharePoint hosted app.

After google search, I found that. We have more articles to add the enterprise keyword column using SP object mode but using JavaScript I couldn’t find. I hope the following explained solution is very useful to you,

Implementation

• Get Host Web URL and App web URL in Document Ready.
• Then call AddEnterpriseColumnToList method.
• Get app context site from AddEnterpriseColumnToList method.
• Get web and Task list.
• Add Enterprise keyword column to List.
• Load the List.
• Execute the request.
• Show result in success method.
• Failure method are used to catch the errors. 

//Varibles Declaration
var appWebURL, hostWebURL, appCtxSite, context;
// This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function ()
{
    hostWebURL = decodeURIComponent(manageQueryStringParameter('SPHostUrl'));
    appWebURL = decodeURIComponent(manageQueryStringParameter('SPAppWebUrl'));
    AddEnterpriseColumnsToList();
});
//Add column to list
function AddEnterpriseColumnsToList()
{
    //get app content site using hostweb URL
    var appCtxSite = new SP.AppContextSite(context, hostWebURL);
    //Get Web using appcontext site
    var web = appCtxSite.get_web();
    //get task list from web
    var list = web.get_lists().getByTitle('Tasks');
    //Get Enterprise column from site
    var field = context.get_site().get_rootWeb().get_fields().getByInternalNameOrTitle("TaxKeyword");
    //Add Enterprise field to List
    list.get_fields().add(field);
    context.load(list);
    context.executeQueryAsync(function ()
    {
        //Success method
        console.log("Field added successfully!!")
    }, function (sender, args)
    {
        //Error method
        console.log("List Items failed" + args.get_message());
    });
}
//Get value from Query string
function manageQueryStringParameter(paramToRetrieve)
{
    var params = document.URL.split("?")[1].split("&");
    var strParams = "";
    for (var i = 0; i < params.length; i = i + 1)
    {
        var singleParam = params[i].split("=");
        if (singleParam[0] == paramToRetrieve)
        {
            return singleParam[1];
        }
    }
}

Note: Make sure to refer the taxonomy.js file in aspx page.



AppManifiest.xml file add the permission level to access the list in your host web.
