If (elem = null)
{
// Skip this loop if no corresponding control exists
Continue;
}

Var trueValue = eval ("values. Rows [0]." + tempValue );

If (trueValue = ''| trueValue = 'null' | trueValue = null)
{
// Skip this loop if the current value is null
Continue;
}
If (elem. tagName = 'select ')
{
// Additional processing of the select Control
For (var j = 0; j <elem. length; j ++)
{

If (trueValue = elem. options [j]. value)
{
// Find the corresponding element and select it
Elem. options [j]. selected = true;
