Add Row Function Not Working

zgoforth

So I am trying to expand my table to where I can add rows of data to it. I added a button, and a function to add values to the table, but when I implement it into the script editor on SharePoint the DataTable doesn't appear, just the header and footer.

What I added:
<input type="button" value="add" id="addbtn" />
$('#addbtn').click(addrow);

function addrow() {
    $('#myTable').dataTable().fnAddData( [
        $('#Program').val(),
        $('#Deliverable').val(),
        $('#To').val(),
        $('#Date').val(),
        $('#Approved').val(),
        $('#Notes').val()
        ] );

}

Here is my full code, I will link a test case in the comments after I make it as I need to use static data instead of the sharepoint ajax request.

kthorngren

but when I implement it into the script editor on SharePoint the DataTable doesn't appear, just the header and footer.

Did you look at your browser's console for errors?

Kevin

kthorngren

BTW, $('#myTable').dataTable().fnAddData( is the legacy version of row.add(). You would be better off using the current syntax.

@kthorngren Uncaught TypeError: Cannot read property 'add' of undefined
This is the error I get

zgoforth

I placed it in the loadData function

 for (i=0; i < urls.length; i++) { //for loop to run through the AJAX until all URLs have been reached
      $.ajax({
        url: urls[i],
        'headers': { 'Accept': 'application/json;odata=nometadata' },
        success: function (data) { // success function which will then execute "GETTING" the data to post it to a object array (data.value)
          data = data;
          var table = $('#myTable').DataTable();
          $('#addbtn').on( 'click', function () {
            myTable.row.add([
        $('#Program').val(),
        $('#Deliverable').val(),
        $('#To').val(),
        $('#Date').val(),
        $('#Approved').val(),
        $('#To').val()      
    ]).draw();
});
          table.rows.add( data.value ).draw();
        }
      }); 
    }
}

kthorngren

$('#addbtn').on( 'click', function () {

You don't want to create an event handler inside a loop. If you do then that event run run once for each iteration through the loop. Move it into document.ready().

Add this line to the event handler:
var myTable = $('#myTable').DataTable();

Before myTable.row.add([.

Kevin

zgoforth

So I did what you said

$(document).ready(function() {
          $('#addbtn').on( 'click', function () {
          var myTable = $('#myTable').DataTable();
        $('#Program').val(),
        $('#Deliverable').val(),
        $('#To').val(),
        $('#Date').val(),
        $('#Approved').val(),
        $('#To').val()     
    ]).draw();

    var collapsedGroups = {}; 
    var top = '';
    var parent = '';
    
  var table = $('#myTable').DataTable( {
    "columns": [
      { "data": "Program", visible: false },
      { "data": "Deliverable", visible: false },
      { "data": "To" },
      { "data": "Date" },
      { "data": "Approved" },
      { "data": "Notes" }
    ],

And I get an error Uncaught SyntaxError: Unexpected token ']'
When I click on the link to send me to the error it is just blank, I do not understand

kthorngren

You are missing myTable.row.add([.

Kevin

zgoforth

Uncaught SyntaxError: Unexpected end of input

I input it here -

$(document).ready(function() {
          $('#addbtn').on( 'click', function () {
          var myTable = $('#myTable').DataTable();
myTable.row.add ([
        $('#Program').val(),
        $('#Deliverable').val(),
        $('#To').val(),
        $('#Date').val(),
        $('#Approved').val(),
        $('#To').val()    
    ]).draw();

kthorngren

I guess you are missing a closing parenthesis ) or bracket } somewhere. if you want to post a link to your page or a test case we can take a look.

@kthorngren will do. I went to https://social.technet.microsoft.com/wiki/contents/articles/31995.sharepoint-2013-working-with-rest-api-using-jquery-ajax.aspx and I am pretty sure I found a partial solution. to send the data with a post. It is completely irrelevant because I still don't have a function to add new items to the DataTable as I still have no idea how...

function sendData() {
    var urls = ["url1","url2","url3","url4","url5","url6","url7","url8"];
       
    var data1 = {
           Program: 'Please provide the Program name here',
           Deliverable: 'Please provide the type of deliverable here',
           To: 'Please provide the recipients email here',
           Date: 'Please provide the submission date here',
           Approved: 'Please provide where or not the deliverable has been approved here',
           Notes: Please provide notes about the deliverable here'
    };
     $.ajax({
        for (i=0; i < urls.length; i++) {
        $.ajax({
                   url: urls[i],
                   method: "POST",
                                 data: JSON.stringify(data),
                   headers: { "Accept": "application/json; odata=verbose",
                                   "X-RequestDigest": $("#__REQUESTDIGEST").val()                                  
                   },
                   success: function (data) {
                              alert('Item added successfully');
                  },
                  error: function (error) {
                      alert("Error: "+ JSON.stringify(error));
                 }
          });
        }
    });
}

If you see the code I supplied at the top of this discussion, I place this sendData() at the very bottom. Is this correct?

zgoforth

https://jsfiddle.net/4euzm8qn/ need to create static data to populate into the table but aside from that there your go

kthorngren

You are getting this error in the browser's console:

editor_console=true:283 Uncaught SyntaxError:

Clicking on the line number it pulls up this line:

           Notes: Please provide notes about the deliverable here'

You are missing an opening ' before Please. Is this what you are wanting help with? If so please work on these types of errors on your own. These are not Datatables issues and take time away from helping with other threads.

@kthorngren I told you I have the sendData down which is unrelated to the DataTable. I still am having trouble grasping how to write new rows to the table

kthorngren

This example show the approach I would take - which is similar to the way Editor data exchanges work.
http://live.datatables.net/qeyenibi/1/edit

This example does not use a server script to save the data to the DB so this part is simulated. But basically you get the new row data from the user, post it to the server, the server script saves it then fetches it and returns the fetch result. Then use row.add() to add the row to the table. This way the user sees what is in the database which might be different than what they entered.
