我正在使用Angular-UI的旋转木马,我需要告诉我的谷歌图表在他们滑入视图后重绘。尽管我已经阅读过,但我似乎无法参与此次活动。
看我的尝试: 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>
在文档加载时:
$('#myC').live('slid.bs.carousel', function (event) { console.log("slid"); } );
应该是这样的: http://jsfiddle.net/9fwuq/ - 非角度ui轮播
也许有更多的Angular方式可以解决我的图表滑入视野的事实?

我有三种方法可以考虑,这取决于您的要求。
请参阅http://plnkr.co/edit/FnI8ZX4UQYS9mDUlrf6o?p=preview以获取示例。
使用$ scope。$监视单个幻灯片以检查它是否变为活动状态。
$scope.$watch('slides[0].active', function (active) {
if (active) {
console.log('slide 0 is active');
}
});
使用$ scope。$ watch使用自定义函数查找活动幻灯片。
$scope.$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);
}
});
使用自定义指令拦截carousel指令的select()函数。
.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);
};
}
};
});
并像这样使用它:
$scope.onSlideChanged = function (nextSlide, direction) {
console.log('onSlideChanged:', direction, nextSlide);
};
并在html模板中:
<carousel interval="myInterval" on-carousel-change="onSlideChanged(nextSlide, direction)">
...
希望这有帮助:)

AngularUI Bootstrap更改了控制器的命名约定,因为thery已将所有控制器的前缀加上前缀uib
,因此以下是runTarm
提供的原始解决方案的更新解决方案:
<强>角:强>
.directive('onCarouselChange', function($parse) {
return {
require: '^uibCarousel',
link: function(scope, element, attrs, carouselCtrl) {
var fn = $parse(attrs.onCarouselChange);
var origSelect = carouselCtrl.select;
carouselCtrl.select = function(nextSlide, direction, nextIndex) {
if (nextSlide !== this.currentSlide) {
fn(scope, {
nextSlide: nextSlide,
direction: direction,
nextIndex: this.indexOfSlide(nextSlide)
});
}
return origSelect.apply(this, arguments);
};
}
};
});
使用TypeScript进行角度化
module App.Directive {
export class CarouselChange implements ng.IDirective {
public require: string = '^uibCarousel';
constructor(private $parse: ng.IParseService) { }
public link: ng.IDirectiveLinkFn = (scope: ng.IScope, element: ng.IAugmentedJQuery, attributes: any, carouselCtrl: any) => {
var fn = this.$parse(attributes.carouselChange);
var origSelect = carouselCtrl.select;
carouselCtrl.select = function(nextSlide, direction) {
if (nextSlide !== this.currentSlide) {
fn(scope, {
nextSlide: nextSlide,
direction: direction
});
}
return origSelect.apply(this, arguments);
};
}
static Factory(): ng.IDirectiveFactory {
var directive: ng.IDirectiveFactory = ($parse: ng.IParseService) => new CarouselChange($parse);
directive['$inject'] = ["$parse"];
return directive;
}
}
}
谢谢,

按照runTarm给出的答案如果你想知道下一张幻灯片的索引,你应该添加如下内容:
.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,nextIndex) {
if (nextSlide !== this.currentSlide) {
fn(scope, {
nextSlide: nextSlide,
direction: direction,
nextIndex:this.indexOfSlide(nextSlide)
});
}
return origSelect.apply(this, arguments);
};
}
};
})
然后,在控制器中,您只需要执行此操作以捕获新索引:
$scope.onSlideChanged = function (nextSlide, direction, nextIndex) {
console.log(nextIndex);
}

我设法修改了runTarm的回答,以便在幻灯片完成滑入视图后调用回调(即滑动动画已完成)。这是我的代码:
.directive('onCarouselChange', function ($animate, $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) {
$animate.on('addClass', nextSlide.$element, function (elem, phase) {
if (phase === 'close') {
fn(scope, {
nextSlide: nextSlide,
direction: direction,
});
$animate.off('addClass', elem);
}
});
}
return origSelect.apply(this, arguments);
};
}
};
});
秘诀在于使用$ animate的事件处理程序在动画结束后调用我们的函数。

这是一个使用控制器的替代方法,介于runTarm的#2和#3之间。
原始HTML +新div:
<carousel id="myC" interval="myInterval">
<slide ng-repeat="slide in slides" active="slide.active">
<div ng-controller="SlideController"> <!-- NEW DIV -->
<img ng-src="{{slide.image}}" style="margin:auto;">
<div class="carousel-caption">
<h4>Slide {{$index}}</h4>
<p>{{slide.text}}</p>
</div>
</div>
</slide>
</carousel>
自定义控制器:
.controller('SlideController',
function($log, $scope) {
var slide = $scope.slide;
$scope.$watch('slide.active', function(newValue) {
if (newValue) {
$log.info("ACTIVE", slide.id);
}
});
});

如果你只想在幻灯片进入视频时开始播放视频,并在幻灯片离开时暂停:
<强> JS 强>
{# Uses angular v1.3.20 & angular-ui-bootstrap v0.13.4 Carousel #}
{% addtoblock "js" %}<script type="text/javascript">
angular.module('videoplay', []).directive('videoAutoCtrl', function() {
return {
require: '^carousel',
link: function(scope, element, attrs) {
var video = element[0];
function setstate(visible) {
if(visible) {
video.play();
} else {
video.pause();
}
}
// Because $watch calls $parse on the 1st arg, the property doesn't need to exist on first load
scope.$parent.$watch('active', setstate);
}
};
});
</script>{% endaddtoblock %}
{% addtoblock "ng-requires" %}videoplay{% endaddtoblock %}
