このような関数を作成し、「行の追加」と「行の削除」のような 2 つのボタンにバインドする方法:

現在動作しているコード例は、空白の一番下の行を編集して新しい行を追加することのみをサポートしています。

結局、自分で思いつきました。これを行う方法について何か良いアイデアがあれば教えてください。

$("#add_row").click(function() {
  var dd = grid.getData();
  dd.splice(dd.length,0,{"title":""});
  grid.invalidateRow(data.length);
  grid.updateRowCount();
  grid.render();
  grid.scrollRowIntoView(dd.length-1)
})

$("#remove_row").click(function() {
  var dd = grid.getData();
  var current_row = grid.getActiveCell().row;
  dd.splice(current_row,1);
  var r = current_row;
  while (r<dd.length){
    grid.invalidateRow(r);
    r++;
  }
  grid.updateRowCount();
  grid.render();
  grid.scrollRowIntoView(current_row-1)
})

それはあなたがやったのと同じようなものですが、私が再レンダリングしない原因は少し異なります。

以下を見てください。

            var data= grid.getData();
            var rows= grid.getSelectedRows();

            for (var i = 0; i < rows.length; i += 1) {
                data.splice(rows[i], 1);
            }
            grid.setData(data, true);

DataView の insertItem と deleteItem を使用すると、より簡単に実行できます。

function add_new_row(){
 item = {
      "id": (Math.round(Math.random()*-10000))
    };
 data_view.insertItem(0, item);
}

function delete_row(e, args){
 var selectedrows = grid.getSelectedRows();  
 var len = selectedrows.length;
 var sure= confirm("Are You Sure You Want to Delete?");   
 if(sure){
  for(var i=0;i<len;i++){                        
   var data = grid.getData().getItem(selectedrows[i]);                         
   data_view.deleteItem(data.id)                                                 
  }
 }
}

次に、ボタンでとじます。

<button onclick="add_new_row()">ADD</button>
<button onclick="delete_row()">DELETE</button>
