弹出悬停不会在动态图像上触发

Question

我有一个 div 有多个图像，每个图像都有一个带有附加内容的弹出窗口，它工作正常。我遇到的问题是我想通过悬停触发图像弹出窗口，我现在使用的方法适用于静态图像但是当我将图像动态添加到主 div 并将鼠标悬停在该图像上时弹出窗口不会触发。如何调整我的代码，使其也支持任何动态添加的元素？任何帮助表示赞赏。提前致谢。

要复制单击附加按钮并滚动到最右侧并将鼠标悬停在新添加的图像上，该图像不会在悬停时触发弹出窗口，但其他静态图像会。

function appendImg() {
  $('.infoBar').append('<div class="imgWrap"><img src="https://source.unsplash.com/user/c_v_r/100x100"></div>')
}

var popOverSettings2 = {
  selector: '.infoBar .imgWrap',
  container: 'body',
  html: true,
  trigger: "manual",
  placement: 'top',
  sanitize: false,
  animation: false,
  content: function() {
    setTimeout(() => {
      $('.popover').css({
        'width': '20%',
        'height': '20%',
        'overflow': 'auto'
      })
    })
    $('.infoBarPopoverContent').append('<p>Popover stuff...</p>')
    return $('.infoBarPopoverContent').html();
  }
}

$(function() {
  $('.infoBar .imgWrap').popover(popOverSettings2)
    .on("mouseenter", function() {
      var _this = this;
      $(this).popover("show");
      $(".popover").on("mouseleave", function() {
        $(_this).popover('hide');
      });
    }).on("mouseleave", function() {
      var _this = this;
      if (!$(".popover:hover").length) {
        $('.popover').popover('hide');
      }
    });
});

据我从您的代码中了解到，您必须像这样在动态追加之后附加事件侦听器

先在函数内部封装事件监听器，然后在append后调用函数

function appendImg() {
  $('.infoBar').append('<div class="imgWrap"><img 
    src="https://source.unsplash.com/user/c_v_r/100x100"></div>')
      addEvent();
 }

var popOverSettings2 = {
  selector: '.infoBar .imgWrap',
  container: 'body',
  html: true,
  trigger: "manual",
  placement: 'top',
  sanitize: false,
  animation: false,
   content: function() {
    setTimeout(() => {
  $('.popover').css({
    'width': '20%',
    'height': '20%',
    'overflow': 'auto'
  })
})
$('.infoBarPopoverContent').append('<p>Popover stuff...</p>')
return $('.infoBarPopoverContent').html();
   }
}
function addEvent(){
$(function() {
  $('.infoBar .imgWrap').popover(popOverSettings2)
    .on("mouseenter", function() {
      var _this = this;
      $(this).popover("show");
      $(".popover").on("mouseleave", function() {
        $(_this).popover('hide');
      });
    }).on("mouseleave", function() {
      var _this = this;
      if (!$(".popover:hover").length) {
        $('.popover').popover('hide');
      }
    });
});
}
addEvent()
