Approval and rejection of buying a house

[averbraeck]

The facilitator now approves or rejects buying of a house. The table to do so has to be implemented, with the appropriate buttons and the communication to the players' app.

[averbraeck]

The screens for approval and rejection have been created:

Warnings still have to be built in for players who cannot afford their house, for a double buy of the same house, or for a bid that is not equal to the market value of the house.

[averbraeck]

Since it is difficult to fill the comment field when the screen is being refreshed every 5 seconds, and since there is little room to show to the facilitator whether the player can afford the house, a popup-screen to fill the comment might help.

[averbraeck]

This is the script that was used to reload the buy/sell tables:

      $(document).ready(function() {
        reloadTables();
      });
      function reloadTables() {
        // store input values before reloading
        var comments = new Array();
        var ids = new Array();
        $(".buy-comment").map(
             function() {
                comments.push($(this).val());
                ids.push($(this).attr('id'));
             });
        var active = document.activeElement;
        console.log("comments: " + comments + ", ids: " + ids);
        $.post("/housinggame-facilitator/reload-tables", {
          reloadTables : 'true'
        }, function(data, status) {
          var tableDiv = document
              .getElementById("facilitator-tables");
          tableDiv.innerHTML = data;
          // return input values after relaoding
          for (let i = 0; i < ids.length; i++) {
              $("#" + ids[i]).val(comments[i]);
          }
          active.focus();
          setTimeout(reloadTables, 5000);
        });
      }

The above script would have to be changed if comments are instead done using a popup window.

[averbraeck]

The approveBuy and rejectBuy scripts are as follows at the moment:

      function approveBuy(playerCode, transactionId) {
         var $comment=$("#comment-" + playerCode).val();
         $.post("/housinggame-facilitator/approve-buy", {
             playerCode : JSON.stringify(playerCode),
             transactionId : JSON.stringify(transactionId),
             comment: JSON.stringify($comment),
             approve: 'APPROVE'
           });
      }
      function rejectBuy(playerCode, transactionId) {
          var $comment=$("#comment-" + playerCode).val();
          $.post("/housinggame-facilitator/approve-buy", {
              playerCode : JSON.stringify(playerCode),
              transactionId : JSON.stringify(transactionId),
              comment: JSON.stringify($comment),
              approve: 'REJECT'
            });
      }

Instead of immediately approving, the script should show a popup with the exact situation for the player on which the approval can be based. By the way, when a house is sold twice, the 'approve' button should not be functional.

Error messages are now displayed when a house transaction is either impossible (APPROVE button greyed out), or not wise for the player (APPROVE still possible):

[averbraeck]

Pressing the "REJECT" button results in a draggable popup that allows for entering a comment before rejecting:

The transaction history for a house in a round is preserved in the database:

Approval / rejection popup is now 2-column:

Approval and rejection for the facilitator work as intended.
