ag-Grid onCellEditingStopped 事件不提供以前的值

Question

I am using ag-Grid onCellEditingStopped event handler to get the changed value of a grid cell.

onCellEditingStopped: function(event) {
    // event.value present the current cell value
    console.log('cellEditingStopped');
}

But it does not provide the previous value (the value before the change happens). Is there anyway to get the previous value ?

My current solution:

I am using onCellEditingStarted event to store the current cell value in a separate variable and use that variable inside the onCellEditingStopped event handler function. But it is not a clear solution.

Thanks

Answer 1

you can use value Setter function for that column as below.

    valueSetter: function (params) {

       console.log(params.oldValue);

       console.log(params.newValue);

       if (params.oldValue !== params.newValue) {
           //params.data["comments"] = params.newValue;
           return true;
       }
       else {
           return false;
       }
    }

I'm using onCellEditingStopped in my Angular application, with agGrid v24.1... and it does have an oldValue and a newValue value in there.

onCellEditingStopped = (_params) => {
  if (_params.newValue != _params.oldValue) {
    //  Do something...
  }
}
