Question

打开模式后，可以单击按钮或从背景/页面复制/选择内容。

在以下位置找到了一些东西：Allow people to click on links under bootstrap modal when modal backdrop is not present 建议使用.modal {bottom：initial！important;}，但这似乎不适用于bootstrap-vue。

解决方案：添加指针事件：无模式css / style

window.dragable = function(a) {
  let header = a.vueTarget.$refs.header;
  let el = a.vueTarget.$refs.content;
  let modal = a.vueTarget.$refs.modal;

  let mousePosition;
  let offset = [0, 0];
  let isDown = false;

  modal.onmousedown = (e) => {
    document.querySelectorAll('.modal').forEach(e => {
      e.parentNode.style.zIndex = e.isSameNode(a.vueTarget.$refs.modal) ? 1041 : 1040;
    })
  }
  header.onmousedown = (e) => {
    isDown = true;
    offset = [
      el.offsetLeft - e.clientX,
      el.offsetTop - e.clientY
    ];
    document.querySelectorAll('.modal').forEach(e => {
      e.parentNode.style.zIndex = e.isSameNode(a.vueTarget.$refs.modal) ? 1041 : 1040;
    })
  }
  header.onmouseup = (e) => {
    isDown = false;
  };
  header.onmousemove = (e) => {
    e.preventDefault();
    if (isDown) {
      mousePosition = {
        x: e.clientX,
        y: e.clientY
      };
      el.style.left = (mousePosition.x + offset[0]) + 'px';
      el.style.top = (mousePosition.y + offset[1]) + 'px';
    }
  };

}

var n = 0;
var app2 = new Vue({
  el: '#app-2',
  methods: {
    dragable: dragable
  }
})

.modal {
  pointer-events: none;
}

Answer 1

您还可以通过hide-backdrop道具来禁用背景，并通过no-close-on-backdrop道具来禁用背景幕关闭。

请参阅https://deploy-preview-3503--bootstrap-vue.netlify.com/docs/components/modal#comp-ref-b-modal

中的文档

Answer 2

我不太记得模态背景课。但是您应该尝试设置背景CSS属性pointer-events: none;，使其对所有鼠标/触摸事件“透明”。

可以使用引导语言
