Cannot call method 'set' of undefined

[brunotiago]

Hi,

I have this code:

<script src="http://ajax.googleapis.com/ajax/libs/prototype/1.6.1.0/prototype.js"></script> <script src="jstorage.js"></script>

function selectChecked() {
var selected = new Array();
var chk_arr = document.getElementsByName("checkbox[]");
var chklength = chk_arr.length;
for(k=0;k< chklength;k++)
{
if (chk_arr[k].checked == true)
selected.push(chk_arr[k].value);
}
$.jStorage.set("links", selected);
}
</script>

And have this error:
Cannot call method 'set' of undefined

I even try change selected to "teststring" and I have the same error

Are you sure you have jStorage loaded on your page since $.jStorage can be undefined only if it not loaded on the page. Additionally I'd suggest you to upgrade Prototype version.

this is happening on sites that use require.js
