javascript - Javascript 代码在 ios 和 Safari 中不起作用

问题描述

我的 javascript 代码似乎适用于所有浏览器和平台，但在 ios 和 Safari 中不起作用，我尝试在首选项中启用 JS，但没有帮助。这是代码的html部分：

var images = [];

      (function() {
        generateCards()
      })();

      var cards = document.querySelectorAll('.card');

      Array.from(cards).forEach(function(card) {
        card.addEventListener('click', function() {
          Array.from(card.querySelectorAll('.back, .front')).forEach(function(el) {
            ['back', 'front'].forEach(function(s) {
              el.classList.toggle(s)
            });
          });
        });
      });

      //Displaying different images on click
      function cardImg(index) {
        var cardNewImg = randomIntFromInterval(2,10);
        if (images[index] !== undefined) 
        {
          images[index] = -1;
        }
          
        while (images.indexOf(cardNewImg)!= -1){
          cardNewImg = randomIntFromInterval(2,11); 
        }  
        images[index] = cardNewImg;
      }

      function generateCards() {
        for (var i = 0; i < 3; i++) {
          cardImg(i);
        }
      }

      function getCard(index) {
        if(!images[index].valid) {
          cardImg(index)
        }
        document["randimg"+(index + 1)].src = "https://lp.rustaro.ru/wp-content/uploads/transformation/cards/" + images[index]+".jpg";
      }

      function randomIntFromInterval(min,max)
      {
        return Math.floor(Math.random()*(max-min+1)+min);
      }

这是工作笔上的链接，当您单击卡片时，它会反转并显示随机图片，但在 safari 和 ios 中，它会在单击卡片并反转后显示卡片。任何帮助和提示将不胜感激。

解决方案

我简单地为 web-kit 转换添加注释，就像您已经使用“-webkit-backface-visibility: hidden”一样。

Chrome 是最优化的浏览器。Safari 和 chrome 共享 web-kit 实现，但 chrome 看起来像是读心术。对于 safari，您必须使用 web-kit 前缀而不需要 chrome。

尝试这个 ：

  var images = [];

  (function() {
    generateCards()
  })();

  var cards = document.querySelectorAll('.card');

  Array.from(cards).forEach(function(card) {
    card.addEventListener('click', function() {
      Array.from(card.querySelectorAll('.back, .front')).forEach(function(el) {
        ['back', 'front'].forEach(function(s) {
          el.classList.toggle(s)
        });
      });
    });
  });

  //Displaying different images on click
  function cardImg(index) {
    var cardNewImg = randomIntFromInterval(2,10);
    if (images[index] !== undefined) 
    {
      images[index] = -1;
    }

    while (images.indexOf(cardNewImg)!= -1){
      cardNewImg = randomIntFromInterval(2,11); 
    }  
    images[index] = cardNewImg;
  }

  function generateCards() {
    for (var i = 0; i < 3; i++) {
      cardImg(i);
    }
  }

  function getCard(index) {
    if(!images[index].valid) {
      cardImg(index)
    }
    document["randimg"+(index + 1)].src = "https://lp.rustaro.ru/wp-content/uploads/transformation/cards/" + images[index]+".jpg";
  }

  function randomIntFromInterval(min,max)
  {
    return Math.floor(Math.random()*(max-min+1)+min);
  }
  
body {
	font-family: sans-serif;
