Alert (selectlength );

Alert ($ ("# type option"). get (I). value );
If ($ ("# type option "). get (I ). value = d. TYPE_ID) // compare the value of option with the value in json. If the value is equal, set this value to the default value.
{
// Var select = document. getElementById ("type ");
// Alert (sel. options [select. selectedIndex]. text );
// Var aa = $ ("# type option"). get (I );
// $ ("# Type option [value = '" + d. TYPE_ID + "']"). attr ('selected', true );
