问题描述
在我的代码中，当用户第一次使用鼠标悬停在div上时执行一个函数，该函数需要30秒才能完成，在30秒内，如果用户再次使用鼠标悬停，则该函数将再次执行，因此我想禁用鼠标悬停事件第二次。有没有javascript或jquery代码来禁用甚至从该div？

第二个想法
可以给你一个想法，假设当鼠标悬停一次，只是在开始操作之前解除鼠标悬停事件的绑定，然后一旦操作结束，再次绑定它们...
I can give you one more idea, suppose when the mouse over is occurred once, just unbind the mouseover event before starting your operations, then as soon as the operations are over, bind them back again...
