Backstretch jQuery点导航

Question

我正在尝试使用点来为后伸滑块构建导航。

目前我正在使用点的值更改为幻灯片，并在点击时显示该值。

让它自动播放1或2张幻灯片并点击第一个点，索引返回01而不是0.这会打破自动播放滑块以及导航。

谷歌搜索后，我似乎找不到任何修改，任何想法？

$(document).ready(function(){
	$(".slider").backstretch([

		duration:3000,
		fade:750,
	});
	$('#dot-0').addClass('selected');

	$('.dot').click(function() {
	    $('.slider').backstretch("show", ($(this).attr('value')));
	    console.log('Value - ' + ($(this).attr('value')));
	    $('.dot').removeClass('selected');
	    $(this).addClass('selected');
	});

	$('.slider').on("backstretch.before", function (e, instance, index) {
		console.log('Index - ' + index);
		var currentSlide = $('#dot-' + index);
		$('.dot').removeClass('selected');
		$(currentSlide).addClass('selected');
	});
});

Answer 1

	$('.dot').first().addClass('selected');
	
	var instance = $(".slider").data("backstretch");
	$('.dot').click(function () {
	  var index = $('.dot').index( $(this) );
	  $('.dot').removeClass('selected');
	  $(this).addClass('selected');
	  instance.show(index);
	  return false;
	});
	
	$('.slider').on("backstretch.before", function (e, instance, index) {
		var currentSlide = $('#dot-' + index);
		$('.dot').removeClass('selected');
		$(currentSlide).addClass('selected');
	});

使用上面的代码修复
