Is there a java script that can make an item re-inherit permissions?

Question

I am trying to determine how to use permissions for a project I am working on and I think I will have to use custom permissions for documents sets. I have read that too many custom permissions can cause performance issues though. If I could add a java script that caused the document set to re-inherit permissions once the status was marked as complete I think that would help keep the number of custom permissions down without requiring an administrator to go in and manually change each one. Is this possible?

Edit

Now I understand how to use the java script to restore permissions inheritance but I am still having trouble with understanding how to trigger this based on a status value I tried the code below but realized I need to use JSOM to get the value of the status category. I know how to get list data with JSOM but all the examples I have seen show outputting this data into a div. This scenario is a bit different and I'm not quite sure what to change.

function ResumeInheritance() {
if(status === "Closed") {
    JSRequest.EnsureSetup();
    var idValue = JSRequest.QueryString["ID"];
    var clientCtx = SP.ClientContext.get_current();
    var list = clientCtx.get_web().get_lists().getByTitle('Tasks');
    var item = list.getItemById(idValue);
    item.resetRoleInheritance();
    clientCtx.executeQueryAsync(function(){alert('success')},function(s,a){alert(a.get_message())});}
}
ResumeInheritance();

Answer 1

var ctx = SP.ClientContext.get_current();
var list = ctx.get_web().get_lists().getByTitle('Calendar');
var item = list.getItemById(121);
item.resetRoleInheritance();
ctx.executeQueryAsync(function(){alert('success')},function(s,a){alert(a.get_message())});

if you are opening the OOTB EditForm from a link on your custom CEWP, execute the following code on click of that link

<a class="itemlink" data-itemid="67" >item title</a>
    

the JS looks like

$('.itemlink').on('click',function(){
 var itemid = $(this).data('itemid');
   OpenPopUpPage('https://server/site/Lists/Tasks/EditForm.aspx?ID=' + itemid, function (sts, data) {
        if (sts === SP.UI.DialogResult.OK) { // item modified
            var ctx = new SP.ClientContext('siteurl');
            var item = ctx.get_web().get_lists().getByTitle('Tasks').getItemById(itemid);
            ctx.load(item);
            ctx.executeQueryAsync(function () {
                var statusval = item.get_fieldValues()['statuscolumninternalname'];
                if (statusval === 'closed') {
                    item.resetRoleInheritance();
                    ctx.executeQueryAsync(function () { alert('success - permissions inherited') }, function (s, a) { alert(a.get_message()) });
                }
            }, function (s, a) { alert(a.get_messsage()) });
        }
    });
});
