不要在鼠标向上事件中关闭模式

【中文标题】不要在鼠标向上事件中关闭模式【英文标题】：Do not close the mode in the mouse up event 【发布时间】：2021-08-23 14:48:40 【问题描述】：

我在我的项目中使用了 micro modal js 包，但是我遇到了问题。当发生鼠标按下或鼠标向上事件时，此模态关闭奖牌范围之外。但我想要 mouse-up 事件不要做任何事情，只需 mouse-down 事件就可以关闭奖牌。 这是我的 html 代码。

let openButton = document.getElementById('open-modal');

openButton.addEventListener('click', function() 
    MicroModal.show('modal-1');
);

【问题讨论】：

听起来像是要在github.com/ghosh/Micromodal/issues报告的问题 【参考方案1】：

解决方案是从您的modal__overlay 中删除data-micromodal-close。这样做会阻止模式在您单击背景时关闭。

<div class="modal__overlay" tabindex="-1">

仅将data-micromodal-close 放在单击时应关闭模式的元素上，例如关闭按钮。

【参考方案2】：

如果您希望在mouseup 987654321 mousedown 987654322 @（aka时选择文本和光标在模态或相反的情况下移动到模态）时，则仍然希望能够关闭模态点击覆盖本身，而不是你可以使用这个：

let openButton = document.getElementById('open-modal');

openButton.addEventListener('click', function() 
    MicroModal.show('modal-1');
);

const overlays = document.querySelectorAll(".modal__overlay");
for(let i = 0; i < overlays.length; i++)

  const overlay = overlays[i];
  let overlayMouseDown;

  /* detect if clicked on overlay itself */
  overlay.addEventListener("mousedown", e => overlayMouseDown = e.target === overlay);
  /* prevent from closing when clicked on overlay and dragged into modal */
  overlay.addEventListener("mouseout", e => overlayMouseDown = false);
  overlay.addEventListener("click", e =>
  
    if (e.target === overlay && !overlayMouseDown)
    
      e.preventDefault();
      e.stopPropagation();
    
  );

【参考方案3】：

我首先从 modal__overlay 中删除了 data-micromodal-close 然后我写了这个 js 代码

let openButton = document.getElementById('open-modal');
const modalOverlay = document.querySelector('.modal__overlay');
openButton.addEventListener('click', function () 
    MicroModal.show('modal-1');
);

modalOverlay.addEventListener('mousedown', (e) => 
    if (e.target.closest('.modal__container'))
        return;
    MicroModal.close('modal-1');
);
