The onselect event for combo boxes activates when a selection is made from the combo choices. Â The event should be specified as a JavaScript expression. Â The expression may use the following two special variables:
value - the value selected by the user
text - the choice text of the option selected by the user
object - reference to the DOM container object for the combo box
Example:
onselect: processSelection(value);
function processSelection(value) {
alert("You selected this value: " + value);
}
