How To Delete A Column In A List Using REST API In SharePoint Online And Office 365

Welcome to an article on “How to create columns in a list using REST API in SharePoint Online and Office 365” where we will see the steps of creating an app using Napa Tool which will help us to delete a column in a list using REST API.

• Open the “NAPA” Office 365 Development Tools through your SharePoint store.
  
  
• Click on Add New Project.
  
  
• It will ask you, what type of app do you want to build?
  
  
  
  
• Select SharePoint Add-in and provide a name to your app and click on Create.
  
  
  
  
• You will see the screen below on the app,
  
  
  
  
• Click on Default.aspx and paste the code below under the “<asp:ContentContentPlaceHolderID="PlaceHolderMain" runat="server">”.
  
  Code:
  

  <div>
      <p>
          <b>Delete Column</b>
          <br />
          <input type="text" id="deletecolumnname" />
          <button id="deletecolumn">DeleteColumn</button>
      </p>
  </div>

  Now on the navigation click on the App.js file and paste the code below removing the previous code completely.
  
  Code:
  

  'use strict';
  varhostweblink;
  varapplink;
  
  // Load the links on app load.
  $(document).ready(function()
  {
      hostweblink = decodeURIComponent(
          getQueryStringParameter("SPHostUrl"));
      applink = decodeURIComponent(
          getQueryStringParameter("SPAppWebUrl"));
  
      //Assign Click event on button
      $("#deletecolumn").click(function(event)
      {
          deletecolumn();
          event.preventDefault();
      });
      varscriptlink = hostweblink + "/_layouts/15/";
      $.getScript(scriptlink + "SP.RequestExecutor.js");
  });
  //function to retrive the clean link
  functiongetQueryStringParameter(paramvalue)
  {
          varparamval = document.URL.split("?")[1].split("&");
          for (vari = 0; i < paramval.length; i = i + 1)
          {
              var paramval1 = paramval[i].split("=");
              if (paramval1[0] == paramvalue) return paramval1[1];
          }
      }
      // Delete column
  functiondeletecolumn()
  {
      vardeletecolumnname = document.getElementById("deletecolumnname").value;
      var play;
      play = new SP.RequestExecutor(applink);
      play.executeAsync
      ({
          url: applink + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('DevData')/fields/getbytitle('" + deletecolumnname + "')?@target='" + hostweblink + "'",
          method: "POST",
          headers:
          {
              "IF-MATCH": "*",
              "X-HTTP-Method": "DELETE"
          },
          success: deletecolumnsuccessful,
          error: deletecolumnfail
      });
  }
  functiondeletecolumnsuccessful(data)
  {
      alert("Column deleted successfully")
  }
  functiondeletecolumnfail(data, errorCode, errorMessage)
  {
      alert("Column could not be deleted, see the error here" + errorMessage);
  }
