js功能不适用于ios

Question

我有以下不适用于ios的代码：

“paginationCustomRender”中的内容有误，但我无法弄明白。

在桌面和Android上运行良好

var swiperH = new Swiper('.swiper-container-h', {
  pagination: '.swiper-pagination-h',
  paginationClickable: true,
  spaceBetween: 4,
  keyboardControl: true,
  slidesPerView: 'auto',
  loop: true,
  speed: 450,
  centeredSlides: true,
  grabCursor: false,
  nextButton: '.h-next',
  prevButton: '.h-prev',
  preventClicks: false,
  preventClicksPropagation: false,
  simulateTouch: false,
  pagination: '.pag-shoes',
  paginationType: "custom",
  paginationCustomRender: function(swiper, current, total) {
    var names = [];
    $(".swiper-slide-ratio").each(function(i) {
      names.push($(this).data("name"));
    });
    var text = "<span>";
    for (let i = 1; i <= total; i++) {
      if (current == i) {
        text += "<span>" + names[i] + "</span>";
      }
    }
    text += "</span>";
    return text;
  }
});

Answer 1

也许不支持ES6语法？将let更改为var

此外，数组从0开始，因此当i == total

时，名称[i]超出范围

如果当前是基于1的使用

for (var i = 0; i < total; i++) {
  if (current == (i+1)) {
    text += "<span>" + names[i] + "</span>";
  }
}
