javascript - 边缘在mouseleave / mouseenter上看不到按钮按下(Edge does not see button press on mouseleave / mouseenter)

Question

Left mouse button was pressed or not - Edge always shows .buttons and .button as 0 .(鼠标左键按下与否- Edge总是显示.buttons和.button为0。)

.which is always 1 .(.which始终为1。) Other browsers work fine.(其他浏览器工作正常。) Other events like click work fine in Edge too.(其他事件（如click在Edge也能正常工作。) Trouble is with mouseleave and mouseenter .(麻烦在于mouseleave和mouseenter 。)

So how can I detect in Edge on mouseleave event if left mouse button was pressed or not?(因此，如果没有按下鼠标左键，如何在发生mouseleave事件时在Edge进行检测？)

PS I can solve it with ugly flag like " isClicked " and update it in all related events like mousedown , mouseup .(PS我可以用丑陋的标志，如“解决它isClicked ”，并在所有相关的活动，如更新mousedown ， mouseup 。)

But it is ugly and bug prone.(但这是丑陋且容易出错的。)   ask by Alex Vovchuk translate from so

Answer 1

The #1 best answer: Tell your users that you do not support MS Edge.(最佳答案＃1：告诉您的用户您不支持MS Edge。)

If that is not an option, then you'll need to track the mouse button status yourself, like(如果这不是一个选项，那么您需要自己跟踪鼠标按钮的状态，例如)

var leftPressed;

function init() {
  document.body.addEventListener("mousedown mouseup") {
    //update leftPressed
  }
}
