Lockable JS function, cannot repeat operation before unlocking operation

(function () {            vared = []; Window. Lockable=function(LOCKF, options) {if(!arguments.length) {varCaller =Arguments.callee.caller; if(Ed.indexof (caller) = = = 1) {Ed.push (caller); Caller.unlock=function() {Ed.splice (Ed.indexof (caller),1);                        }; return; }                    return true; }                varEmpty =function() {}, on= Options && Options.On | |empty, off= Options && Options.off | |empty, repeat= Options && Options.repeat | |empty, ING, RI= 1; if(typeofoptions = = = "function") {off=options; }                varf =function () {                    "Use Strick"if(ing) {repeat (RI++); return; }                    if(On ()) {ing=false; return; }                    varR = lockf.apply ( This, arguments); if(typeofr = = "Undefined") {ing=true; } Else{ing= !!R;                }                }; F.unlock=function() {ing=false;                off.apply (arguments);                }; returnF; }        })();

How to use:

var functionname = lockable (function() {  ///needs long time.  111);　　

Or:

function fn () {    if(lockable ()) {        return;    }     // needs long time     Fn.unlock ();}

SetInterval (FN, 111);
