农业网格 |只获取完全改变的单元格数据

Question

我目前正在使用 Ag-grid js 库进行单元格编辑和保存数据。我想出显示数据。并获取编辑数据。我有自定义单元格 ID，即包括 db table 列和行 ID。我打算在完成编辑后将其发送到服务器。我使用 MySQL 数据库来存储数据。自定义单元 ID 如下所示 "1,4,1,12,47".
编辑完成后数据为return整行数据集。我只需要更改单元格数据对象。

我不确定是否有任何其他方法可以做到这一点，但是，这是您可以使用列名的替代解决方案，因为列名与 event.data 匹配所以使用该列名获取所需的数据，例如 event.data[cols] 其中 cols 是 event.column.colDef.headerName.

演示代码 :

// specify the columns
const columnDefs = [

  {
    field: "model.value",
    headerName: "Model"
  },
  {
    field: "make.value",
    headerName: "Make"
  },
  {
    field: "price.value",
    headerName: "Price"
  },
];

const autoGroupColumnDef = {

}

// let the grid know which columns and what data to use
const gridOptions = {
  columnDefs: columnDefs,

  defaultColDef: {
    flex: 1,
    minWidth: 110,
    editable: true,
    resizable: true,
  },
  onCellValueChanged: onCellValueChanged,
};



function onCellValueChanged(event) {
  console.clear()
  console.log('data after changes is: ', event.data);
  var cols = event.column.colDef.headerName.toLowerCase()
  console.log('data column name--', event.column.colDef.headerName.toLowerCase());
  console.log('data after changes is: ', event.data[cols]);
}





// setup the grid after the page has finished loading
document.addEventListener('DOMContentLoaded', function() {

  // lookup the container we want the Grid to use
  const eGridDiv = document.querySelector('#myGrid');

  // create the grid passing in the div to use together with the columns & data we want to use
  new agGrid.Grid(eGridDiv, gridOptions);

  let jsonObj = `[
  { "make":{"value": "Toyota", "cell_id":"22,331,1"}, "model": {"value": "Hilux", "cell_id":"22,331,2"}, "price": {"value": 80899, "cell_id":"22,331,3"} },
   { "make":{"value": "MBW", "cell_id":"22,332,1"}, "model": {"value": "I8", "cell_id":"22,332,2"}, "price": {"value": 300899, "cell_id":"22,332,3"} }
]`;


  gridOptions.api.setRowData(JSON.parse(jsonObj));




  gridOptions.api.sizeColumnsToFit();
});
