Talking about the Clear of Option in Object

INTLENGTH is Option: Document.all ("LSTUSERID"). Options.Length;

LSTUSERID is

ID = LSTUSERID

> Object:

method one:

FOR

VAR i = 0; I

{

Document.all ("LSTUSERID"). Options.Remove (i);

}

Method Two:

While (Document.all ("LSTUSERID"). Options.length> 0)

{

Document.all ("LSTUSERID"). Option.remove (0);

}

Method can clear the

object and will report an error. Because when Document.all ("LSTUSERID"). Options [0] is deleted Document.all ("LSTUSERID"). Options [intlength-1] is no longer existed.

So there is a problem from the first delete from the last delete.

The method is to empty because Document.all ("LSTUSERID"). Options [0] deletes Document.all ("LSTUSERID"). Options [1] becomes Document.all ("LSTUSERID"). Options [ 0]. The last one is deleted until it is deleted.
