angular ng-click防止重复提交实例

方法一：点击后，让button的状态变为disable

js指令：

.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:

复制代码代码如下:

<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

方法二：在app.config里面，重写ng-click事件，设置一定事件内不能重复点击


$provide.decorator('ngClickDirective',['$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;
    }]);
