HI All,

How to get the length of Select box option in catalog client script.

var sel = g_form.getControl('from_role');

alert(sel.options.length); giving 0 but it has multiple options.

Hi

the short form is

alert(g_form.getElement('from_role').options.length);

The long form with looping through the values is:

var values = [];
var sel    = g_form.getElement('from_role');

for (var i = 0, n = sel.options.length; i < n; i++) {
   values.push(sel.options[i].value);
}

alert (values.length);

Kind regards
Maik
