解决重复点击onClick事件，多次触发问题

app.config([‘$provide‘, function ($provide) {
        $provide.decorator(‘ngClickDirective‘,[‘$delegate‘,‘$timeout‘, function ($delegate,$timeout) {
            var original = $delegate[0].compile;
                  var delay = 500;
            $delegate[0].compile = function (element, attrs, transclude) {

                var disabled = false;
                function onClick(evt) {
                    if (disabled) {
                        evt.preventDefault();
                        evt.stopImmediatePropagation();
                    } else {
                        disabled = true;
                        $timeout(function () { disabled = false; }, delay, false);
                    }
                }
                //   scope.$on(‘$destroy‘, function () { iElement.off(‘click‘, onClick); });
                element.on(‘click‘, onClick);

                return original(element, attrs, transclude);
            };
            return $delegate;
        }]);
    }]);
