how to handle spreadsheet events in javascript

StartEdit event Occurs whenever the user enters edit mode while the mouse pointer is in a cell.

<script language="javascript" for="spread" event="StartEdit (Selection, InitialValue, Cancel, ErrorDescription)">
<!--
 spread_StartEdit (Selection, InitialValue, Cancel, ErrorDescription);
//-->
</script>

EndEdit event occurs whenever the user switches from edit mode on the specified Spreadsheet Control. You can use this event to validate data entry in a worksheet.

<script language="javascript" for="spread" event="EndEdit(Accept,FinalValue,Cancel,ErrorDescription)">
<!--
 spread_EndEdit(Accept, FinalValue, Cancel, ErrorDescription);
//-->
</script>

<script language="javascript">

function spread_StartEdit (Selection, InitialValue, Cancel, ErrorDescription)
{
    /// you need to disable event at first line of this function to fix the runtime error R6025 Pure virtual function call
    spread.EnableEvents = false;

    try
    {    
        //Write your code
    }
    catch(err)
    {
          //Catch any error
    }
    finally
    {
         //Enable event again
        spread.EnableEvents = true;
    }
}

function spread_EndEdit (Selection, InitialValue, Cancel, ErrorDescription)
{
    /// you need to disable event at first line of this function to fix the runtime error R6025 Pure virtual function call
    spread.EnableEvents = false;
    try
    {    
        //Write your code
    }
    catch(err)
    {
         //Catch any error
    }
    finally
    {
         //Enable event again
        spread.EnableEvents = true;
    }
}

</script>
