你如何绑定到 Angular-UI 的 Carousel Slide Events? [英] How do you Bind to Angular-UI's Carousel Slide Events?

问题描述

我正在使用 Angular-UI 的轮播，我需要告诉我的 google 图表在它们滑入视图后重新绘制.不管我读过什么，我似乎都无法融入这个事件.

看我的尝试:http://plnkr.co/edit/Dt0wdzeimBcDlOONRiJJ?p=preview

HTML:

<slide ng-repeat="slide in slides" active="slide.active"><img ng-src="{{slide.image}}" style="margin:auto;"><div class="carousel-caption"><h4>滑动{{$index}}</h4><p>{{slide.text}}</p>

</幻灯片></轮播>

在文档加载时:

$('#myC').live('slid.bs.carousel', function (event) { console.log("slid"); } );

它应该像这样工作:http://jsfiddle.net/9fwuq/ - 非 angular-ui 轮播

也许有一种更 Angular 的方式可以了解我的图表已滑入视图这一事实?

解决方案

我可以想到 3 种方法，这取决于您的要求.

有关示例，请参阅 http://plnkr.co/edit/FnI8ZX4UQYS9mDUlrf6o?p=preview.

1. 对单个幻灯片使用 $scope.$watch 来检查它是否处于活动状态.

   $scope.$watch('slides[0].active', function (active) {如果(活动){console.log('幻灯片 0 处于活动状态');}});

2. 使用带有自定义函数的 $scope.$watch 来查找活动幻灯片.

   $scope.$watch(function () {for (var i = 0; i < slides.length; i++) {如果(幻灯片 [i].active){返回幻灯片[i];}}}, 函数 (currentSlide, previousSlide) {if (currentSlide !== previousSlide) {console.log('currentSlide:', currentSlide);}});

3. 使用自定义指令拦截 carousel 指令的 select() 函数.

   .directive('onCarouselChange', function ($parse) {返回 {要求:'轮播'，链接:函数(范围、元素、属性、轮播控件){var fn = $parse(attrs.onCarouselChange);var origSelect = carouselCtrl.select;carouselCtrl.select = 函数(nextSlide，方向){if (nextSlide !== this.currentSlide) {fn(范围，{nextSlide:nextSlide，方向:方向，});}返回 origSelect.apply(this, arguments);};}};});

   并像这样使用它:

   $scope.onSlideChanged = function (nextSlide, direction) {console.log('onSlideChanged:', 方向, nextSlide);};

   在 html 模板中:

希望这有助于:)

I'm using Angular-UI's carousel and I need to tell my google charts to redraw after they have slid into view. In spite of what I've read, I can't seem to hook into the event.

See my attempt: http://plnkr.co/edit/Dt0wdzeimBcDlOONRiJJ?p=preview

HTML:

<carousel id="myC" interval="myInterval">
  <slide ng-repeat="slide in slides" active="slide.active">
    <img ng-src="{{slide.image}}" style="margin:auto;">
    <div class="carousel-caption">
      <h4>Slide {{$index}}</h4>
      <p>{{slide.text}}</p>
    </div>
  </slide>
</carousel>

On document load:

$('#myC').live('slid.bs.carousel', function (event) { console.log("slid"); } );

It should work something like this: http://jsfiddle.net/9fwuq/ - non-angular-ui carousel

Perhaps there is a more Angular way to hook into the fact that my chart has slid into view?

解决方案

There are 3 ways I can think of and that depends of your requirement.

Please see http://plnkr.co/edit/FnI8ZX4UQYS9mDUlrf6o?p=preview for examples.

1. use $scope.$watch for an individual slide to check if it is become active.

   $scope.$watch('slides[0].active', function (active) {
     if (active) {
       console.log('slide 0 is active');
     }
   });
   

2. use $scope.$watch with custom function to find an active slide.

   $scope.$watch(function () {
     for (var i = 0; i < slides.length; i++) {
       if (slides[i].active) {
         return slides[i];
       }
     }
   }, function (currentSlide, previousSlide) {
     if (currentSlide !== previousSlide) {
       console.log('currentSlide:', currentSlide);
     }
   });
   

3. use a custom directive to intercept select() function of the carousel directive.

   .directive('onCarouselChange', function ($parse) {
     return {
       require: 'carousel',
       link: function (scope, element, attrs, carouselCtrl) {
         var fn = $parse(attrs.onCarouselChange);
         var origSelect = carouselCtrl.select;
         carouselCtrl.select = function (nextSlide, direction) {
           if (nextSlide !== this.currentSlide) {
             fn(scope, {
               nextSlide: nextSlide,
               direction: direction,
             });
           }
           return origSelect.apply(this, arguments);
         };
       }
     };
   });
   

   and use it like this:

   $scope.onSlideChanged = function (nextSlide, direction) {
       console.log('onSlideChanged:', direction, nextSlide);
   };
   

   and in html template:

   <carousel interval="myInterval" on-carousel-change="onSlideChanged(nextSlide, direction)">
   ...
   

Hope this help : )
