jQuery动画坚持快速悬停

Question

如果您将鼠标缓慢悬停在元素上，动画将正常工作。绿色层从左侧重叠，然后从顶部开始，黄色层与绿色层重叠。当鼠标离开元素时，这种重叠应该会自行撤消，首先撤消黄色重叠，然后撤消绿色重叠。

但是如果光标悬停在它上面的速度太快，动画就会卡在黄色重叠处，直到你重新鼠标悬停然后鼠标移出。我尝试在每个.animate 方法之前添加.stop(false, true) jQuery 方法，这是我读到的解决了类似问题的方法，但这没有用。我通过在 .animate 函数之前链接它来尝试它，我尝试了它的几乎所有变体，在所有函数上，以及 .stop(true,true);。

如果鼠标悬停部分在光标离开元素之前没有完成，有没有办法阻止鼠标悬停部分触发？

$(document).ready(function() {
  $('#con').hover(
    function() { // handlerIn
      $('#crossX').animate({'width': '115px'}, function() {
        $('#crossY').animate({'height': '115px'})
      })
    },
    function() { // handlerOut
      $('#crossY').animate({'height': '15px'}, function() {
        $('#crossX').animate({'width': '15px'})
      })
    }
  )
});

#con {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  width: 130px;
  height: 130px;
  overflow: hidden;
  //background-color: black;
}
#one {
  width: 100px;
  height: 100px;
  background-color: lightgrey;
  color:black
}
#crossX {
  position: absolute;
  top: 15px;
  left: 0px;
  width: 15px;
  height: 100px;
  background-color:  green;
  color: yellow;

#crossY {
  position: absolute;
  top: 0px;
  left: 15px;
  width: 100px;
  height: 15px;
  background-color:  yellow;

#black {

  height: 100px;
  border: 15px solid black;

Answer 1

通过以下解决方案，可以保证“鼠标离开部分”仅在“鼠标进入部分”被填充后运行（反之亦然）。

此外，该脚本还负责处理快速用户操作时的情况：“进入 > 离开 > 进入”状态保持就像用户没有完成“快速离开”一样。 所以实际上这应该可以达到你想要达到的效果（至少我希望如此）。

var mouseEnter = function() {
      // console.log('in');
      sPosition = 'in';
      if ( !mouseEnterIsDone || !mouseLeaveIsDone ) return mouseEnterIsWaiting = true;
      mouseEnterIsDone = false;
      $('#crossX').animate({'width':'115px'}, function(){
        $.when($('#crossY').animate({'height': '115px'})).then(function(){sanitizeAnimation('enter')})
      })
    },
    mouseLeave = function() {
      // console.log('out');
      sPosition = 'out';
      if ( !mouseEnterIsDone || !mouseLeaveIsDone ) return mouseLeaveIsWaiting = true;
      mouseLeaveIsDone = false;
      $('#crossY').animate({'height':'15px'}, function(){
        $.when($('#crossX').animate({'width': '15px'})).then(function(){sanitizeAnimation('leave')})
      })
    },
    sanitizeAnimation = function( sMode ){
      if ( 'enter' == sMode )
          mouseEnterIsDone = true;
      else
          mouseLeaveIsDone = true;
      if ( 'in' == sPosition ) {
        if ( mouseEnterIsWaiting ) {
          mouseEnterIsWaiting = false;
          mouseEnter();
        }
      } else {
        if ( mouseLeaveIsWaiting ) {
          mouseLeaveIsWaiting = false;
          mouseLeave();
        }
      }
    },
    mouseEnterIsDone = true,
    mouseLeaveIsDone = true,
    mouseEnterIsWaiting = false,
    mouseLeaveIsWaiting = false,
    sPosition = 'out';

$(document).ready(function(){
  $('#con').hover(mouseEnter, mouseLeave);
});

body {
  padding: 5%;
}

#con {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  width: 130px;
  height: 130px;

#crossY {

  top: 0px;
  left: 15px;
  width: 100px;

}

  width: 100px;
  height: 100px;
  border: 15px solid black;

$("#con").mouseenter(function() {

});
