The Code is as follows:

Function listMove (main, follow, hidetextbox, isBack, index ){
If (index <0)
Return;
Var o = undefined;
Var source;
Var distinct;
Var dddd;
If (! IsBack ){
// A bug exists in IE6 using getElementById
Source = $ ('#' + main); // your own Doc ument. getElementById (main );
Distinct = $ ('#' + follow); // specify your doc ument. getElementById (follow );
}
Else {
Source = $ ('#' + follow); // specify your doc ument. getElementById (follow );
Distinct = $ ('#' + main); // specify your doc ument. getElementById (main );
}
Var hid = $ ('#' + hidetextbox) [0]; // document. getElementById (hidetextbox );
If (index! = Undefined ){
Var op = "option: eq (" + index + ")";
Source. find (op). each (function (){
Distinct. append (""+ $ (This). text () +"");
$ (This). remove ();
});
}
Else {
Source. find ("option: selected"). each (function (){
$ (This). remove ();
Distinct. append (""+ $ (This). text () +"");
});
}
Var str = "";
// Traverse Listbox to obtain the value of the selected item
$ ('#' + Main + 'option'). each (function (){
Str + = $ (this). val () + ',';
});
Hid. value = str;
}
