用Nivo滑块显示幻灯片计数 [英] Showing Slide Count with Nivo Slider

问题描述

我想在我的滑块上将幻灯片计数显示为 2 of 10 。如何使用过渡 3 of 10 ， 4 of 10 （当滑块随幻灯片移动时） &安培; 10 of 10 （如果点击相应的缩略图）？

I would like to show the slide count as 2 of 10 on my slider. How do I make it work with the transitions 3 of 10, 4 of 10 (as the slider moves with slides) & 7 of 10 (if the corresponding thumbnail was clicked)?

推荐答案

您可以将当前幻灯片设为 current_slide_no = jQuery（'#nivo-slider'）。data（'nivo：vars'）。currentSlide; 将1添加为索引从0开始。

You can have the current slide no as current_slide_no = jQuery('#nivo-slider').data('nivo:vars').currentSlide; Add 1 to it as index starts from 0.

使用 afterChange 属性在初始化NIVO滑块时更改当前幻灯片编号。

Use afterChange attribute to change the current slide number while initializing the NIVO slider.

所以，我得到它的工作

<script type="text/javascript">
    jQuery(document).ready(function(){
        var total = jQuery('#nivo-slider img').length;
        var current_slide_no = 1; // garbage
        // var rand = Math.floor(Math.random()*total);
        jQuery('#nivo-slider').nivoSlider({
            effect:'fade', //Specify sets like: 'fold,fade,sliceDown,slideInLeft'
            animSpeed:600, //Slide transition speed
            pauseTime:30000,
            directionNav:false, //Next and Prev
            // directionNavHide:true, //Only show on hover
            controlNav:true, //1,2,3...
                controlNavThumbs:true, //Use thumbnails for Control Nav
            controlNavThumbsFromRel:true, //Use image rel for thumbs
            pauseOnHover:false, //Stop animation while hovering
            //captionOpacity:0.3, //Universal caption opacity
            startSlide:0, //Set starting Slide (0 index)
            // keyboardNav:true //Use left and right arrows
            afterChange: function(){
                current_slide_no = jQuery('#nivo-slider').data('nivo:vars').currentSlide;
                jQuery('#nivo-slider-status > .current-slide').html(current_slide_no+1);
            }
        });
        jQuery('#nivo-slider-status').show();
        jQuery('#nivo-slider-status > .total-slides').html(total);
        current_slide_no = jQuery('#nivo-slider').data('nivo:vars').currentSlide;
        jQuery('#nivo-slider-status > .current-slide').html(current_slide_no+1);
    });
    </script>

和我的html（应该在NIVO滑块DIV之外）是

and my html (should be outside the NIVO slider DIV) is

<div id="nivo-slider-status" class="alignright">
    <span class="current-slide"></span> of <span class="total-slides"></span>
</div>
