无法在 javascript 上打开多个模态图像

Question

在此处创建了 FIDDLE： https://jsfiddle.net/jqqn2gg7/

我在上面 post 编辑了 fiddle 关于我的问题。如果你去 "Bunny1" 你可以将鼠标悬停在兔子上，你会看到你可以打开第一个，但第二个甚至不会让步。我尝试了一切，甚至第一只兔子也停止了工作。你回去工作了。

这里缺少什么？

我还尝试使用 "Escape" 按钮关闭而不是仅使用 "X" 按钮。

我会 post 我的问题代码在这里：

和 javascript:

$(function() {
  var selectedClass = "";
  $(".fil-cat").click(function() {
    selectedClass = $(this).attr("data-rel");
    $("#portfolio").fadeTo(100, 0.1);
    $("#portfolio div").not("." + selectedClass).fadeOut().removeClass('scale-anm');
    setTimeout(function() {
      $("." + selectedClass).fadeIn().addClass('scale-anm');
      $("#portfolio").fadeTo(300, 1);
    }, 300);

  });
});

// DAT GALLERY

// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var modalImg2 = document.getElementById("img02");
var captionText = document.getElementById("caption");
img.onclick = function() {
  modal.style.display = "block";
  modalImg.src = this.src;
  modalImg2.src = this.src;
  captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

// end of gallery

Answer 1

您可以使用 getElementsByClassName 而不是 getElementById。

检查此 fiddle：fiddle

Answer 2

这是因为您使用 getElementByID 仅挑出其中一张图片，而 ID 仅适用于一张图片。您不能有多个具有相同 ID 的 ID。

另外...因为您在顶部使用了 jquery，所以不妨坚持使用它，而不要在其余部分使用 vanilla js。所以就这样做吧，它应该是好的。

// Apply click handler to all tile elements,
$('.tile').click(function(){
   // Get image inside tile element
  var img = $(this).find('img');
  // Update modal with image data
  $("#img01").attr('src', img.attr('src'));
  $("#img02").attr('src', img.attr('src'));
  $('#caption').html(img.attr('alt'));
  $('#myModal').css('display','block');
});

// Close modal
$('.close').click(function(){
  $('#myModal').css('display','none');
})

这样更加一致和简洁。

同时提供 .tile class 光标指针，这样您就可以点击它了。

 .tile { cursor:pointer; }
