How to hide Shared With ECB menu item for non-admin users via javascript

In Sharepoint lists and doclib there is possibility to check which users have access to list item or file using “Shared With”. Often this item should be hidden for non-admin users. Below javascript allows to hide “Shared With” ECB menu item for users which are not site admins:

SP.SOD.executeFunc("sp.js", "SP.ClientContext", function () {
	var ctx = SP.ClientContext.get_current();
	var user = ctx.get_web().get_currentUser();
	ctx.load(user);
	ctx.executeQueryAsync(
		Function.createDelegate(this, function () {
			var isSiteAdmin = user.get_isSiteAdmin();
			if (isSiteAdmin) {
				return;
			}
			jQuery("td.ms-list-itemLink-td").click(function(){
				setTimeout(function(){
					jQuery("span.js-callout-ecbActionDownArrow a").click(function(){
						setTimeout(function(){
							jQuery("li[text='Shared With']").hide();
						}, 200);
					});
				}, 200);
			});
		}),
		Function.createDelegate(this, function (sender, args) {
			// log error
		}));
});

Here we first check whether current user site admin or not. After that we add our own event handler for ECB click item which hides “Shared With” command. Little delay is needed in order to allow ECB sub menu to be displayed after original click handler will be triggered.
