Question

我试图在鼠标位于跨度上时使用计时器启动一个功能，当它离开跨度时，功能计时器停止。

我的问题是计时器没有停止。

错误在哪里？

<script>
$("#first").mouseover(function() {
  var tid = setTimeout(loop, 1500); 

  function loop(){
//code
    tid = setTimeout(loop, 1500);
  }
});
$("#first").mouseleave(function(){
  clearTimeout(tid);
});
</script>

Answer 1

尝试使用tid

在loop之外声明.mouseover，.one()功能

由于javascript范围，因此mouseover无法访问它。

有效地你正在做mouseleave

鼠标离开jQuery时停止超时
