Javascript引用幻灯片

问题描述

在我的Javascript幻灯片播放中遇到困难：

由于某些原因，当我将网站加载到chrome上时，似乎没有在第一张幻灯片上显示第一条报价。仅当我单击“预览” /“下一个”箭头或幻灯片底部的点时才会显示。

请有人提供解决方案，使我在打开网站后立即显示第一条报价。

代码如下所示：

// JavaScript Document
var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {
    slideIndex = 1
  }
  if (n < 1) {
    slideIndex = slides.length
  }
  for (i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
    dots[i].className = dots[i].className.replace(" active","");
  }
  slides[slideIndex - 1].style.display = "block";
  dots[slideIndex - 1].className += " active";
}
