最佳答案

您必须将 display: block 应用于 .overlay .modal.open。

这是因为即使您的 .open 类附加到您的 .modal，display: none 来自 .modal 需要被 display: block 覆盖才能使特定的 .modal 可见。

.overlay .modal.open {
  opacity: 1;
  pointer-events: inherit;
  display: block;
  width: 60%;
  height: 60%;
  margin: auto;
}

引用代码:

$(".modal").each(function() {
  $(this).wrap('<div class="overlay"></div>')
});

$(".open-modal").on('click', function(e) {
  e.preventDefault();
  e.stopImmediatePropagation;

  var $this = $(this),
    modal = $($this).data("modal");

  $(modal).parents(".overlay").addClass("open");
  setTimeout(function() {
    $(modal).addClass("open");
  }, 350);

  $(document).on('click', function(e) {
    var target = $(e.target);

    if ($(target).hasClass("overlay")) {
      $(target).find(".modal").each(function() {
        $(this).removeClass("open");
      });
      setTimeout(function() {
        $(target).removeClass("open");
      }, 350);
    }

  });

});

$(".close-modal").on('click', function(e) {
  e.preventDefault();
  e.stopImmediatePropagation;

  var $this = $(this),
    modal = $($this).data("modal");

  $(modal).removeClass("open");
  setTimeout(function() {
    $(modal).parents(".overlay").removeClass("open");
  }, 350);

});
