Custom Carousel Intervals?
javascript, jquery, twitter-bootstrap, twitter-bootstrap-3
Solution
You can create a custom attribute that denotes how long the slide should be visible for, pull that out for the active item on the `slide.bs.carousel` or `slid.bs.carousel` events (whichever you prefer/works best for you), then set it as a timeout to go to the next slide.
$('#carousel-example-generic').on('slide.bs.carousel', function() {
var interval = $('div.item.active').attr('duration');
setTimeout(function() {
$('.carousel').carousel('next');
}, interval);
});

Problem
In Bootstrap 3, with jQuery is there a way to sort by the index of my carousel and add custom intervals of each slide so that I can have one slide 10000ms and another 500ms etc? I know you can set the data-interval attribute but this sets the speed for all slides as you can't add a custom interval attribute to each item. ``` data-interval="3000" ``` My carousel is setup like this: ``` <div id="carousel" class="carousel slide"> <div class="carousel-inner"> <div class="item active"> <a href="#"> <img class="img-responsive" src=""> </a> </div> <div class="item"> <a href="#"> <img class="img-responsive" src=""> </a> </div> <div class="item"> <a href="#"> <img class="img-responsive" src=""> </a> </div> <div class="item"> <a href="#" > <img class="img-responsive" src=""> </a> </div> </div> ```
