How to hide button button on state change

[ritaaudi]

Hi: I want to be able to hide the Close Complete button on the RITM form when the state changes to Closed incomplete. I tried this but it didn't work:

I don't get the alert 2 popup. Any idea? Thank you!

in Ui Action only u can put condition in which state u want to show that field 

ex:

Yes I can do that part, no problem but the script is not working:

if(g_form.getValue('state') == 4){

    alert("1");

    var items = $$('close_sc_task').each(function(item) {

            if (item.innerHTML.indexOf('Close Complete') > -1) {

                alert("2");

                item.hide();

            }

        });

It's erroring out on the "$$"

Try this:-

if(g_form.getValue('state') == 4){

    alert("1");

    var items = $$('#close_sc_task').each(function(item) {

            if (item.innerHTML.indexOf('Close Complete') > -1) {

                alert("2");

                item.hide();

            }

        });

also check whether close_sc_task is a Action name of your UI action

Still gives me error: onChange script error: TypeError: $$ is not a function function () { [native code] }
