Bootstrap 4 Carousel:每张幻灯片上的单独数据间隔 [英] Bootstrap 4 Carousel: Individual data-interval on each slide
问题描述
我想为传送带的每个幻灯片设置数据间隔。
在这里stackoverflow我发现这个案件的JavaScript代码片段,但它不能很好地工作。 (中概述的方法。因此它适用于Bootstrap 4传送带。国际海事组织,这是一个比连接到jQuery事件更清洁的方法。
它覆盖 https://www.codeply.com/go/sGAOcxEzV8 I want to set the data-interval for each slide of the carousel.
Here on stackoverflow I found a JavaScript snippet for this case, but it doesn't work well. (Twitter Bootstrap Carousel slide duration)
Each slide has its data-interval set inline in html with ms from 3000 to 7000 on five slides. The real duration of the slides does not fit to my expectations and the code. Example: I set the interval to 3000 and the slide is shown around 7-8 seconds. The js-file is written in the footer area of the site. Here is the js code: One part of the carousel: Note: I have changed the lines carousel-control-next and -prev. (It was -left and -right before). Does anyone have a good idea so solve this problem? I modified the approach outlined in Bass Jobsen's answer for Bootstrap 3.x so that it works for the Bootstrap 4 carousel. IMO, this is a much cleaner approach than hooking into the jQuery events. It overrides the https://www.codeply.com/go/sGAOcxEzV8 这篇关于Bootstrap 4 Carousel:每张幻灯片上的单独数据间隔的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋! this._config.interval
