For loop doesn't work under formapi

Hi all,

Currently, i want to get all the selected option values of a multiple select item.
But after i test, I find if i use for loop, then return null.

i open a saved dcr, item4 is a multiple select item. When open it, i need to get all the selected option values of this item. So i write js something like,
for example:
[php]
var item4;
var arr = new Array();
var results = new Array();
item4 = IWDatacapture.getItem("/option/dynamic_multiple");
arr = item4.getValue();

/* for(int i=0; i {
results=item4.getOptions()[arr].value;
}
alert(results[0]+results[1]);
*/
alert(item4.getOptions()[arr[0]].value+item4.getOptions()[arr[1]].value);

[/php]
if i commend for loop, alert works and can get correct values.

but if i use above for loop then no alert promot.

Is anybody meet this issue before? expect your advise,thx

Its problem in your variable declaration.
Change int i=0 to var i=0;
