Method 1:After clicking, change the status of the button to disable

js command:

.directive('clickAndDisable', function() {
        return {
            scope: {
                clickAndDisable: '&'            },            link: function(scope, iElement, iAttrs) {
                iElement.bind('click', function() {
                    iElement.prop('disabled',true);
                    scope.clickAndDisable().finally(function() {
                        iElement.prop('disabled',false);
                    })
                });
            }
        };
    })

html:

<button type="button" class="btn btn-info btn-bordered waves-effect w-md waves-light" click-and-disable="next()">下一步</button>   //把 ng-click 改为指令click-and-disable
<br>

Method 2: In app.config, rewrite the ng-click event and set it to prevent repeated clicks within a certain event

$provide.decorator('ngClickDirective',['$delegate','$timeout', function ($delegate,$timeout) {  //记得在config里注入$provide
            var original = $delegate[0].compile;
            var delay = 500;//设置间隔时间
            $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;
        }]);
