jquery - 在 setInterval() 中添加悬停暂停？

Question

您好，这是我的用于幻灯片放映的 jquery 函数以及其他内置函数。当我将鼠标悬停在整个 div 上时，我一直试图让它暂停。帮帮我吧!

$(function() {
var timer = setInterval( showDiv, 5000);
var counter = 2;
function showDiv() {

if (counter ==0) { counter++; return; }

$('div','#slide-show-overall')
  .stop()
  .fadeOut('slow')
  .filter( function() { return this.id.match('picture-set-' + counter); })   
  .fadeIn('slow');
  if (counter ==2) { slideWings();} //extra functions
  if (counter ==1) { resetWings();} //extra functions
counter == 3? counter = 1 : counter++; 
}
});
});

<div style="position:absolute;width:1000px;height:600;top:0px;z-index:0;overflow:hidden;" id="slide-show-overall" >
<div id="picture-set-1" style="">
<img src="images/3.jpg" align=left width=1000>
</div>
<div id="picture-set-2" style="display:none;">
<img src="images/1.jpg" align=left width=1000>
<img src="images/wing_left.png" align=left height=200 width=200 style="margin-top:-900px;margin-left:230px;" id="wing-left-1">
<img src="images/wing_right.png" align=left height=200 width=200 style="margin-    top:-900px;margin-left:830px;" id="wing-right-1">
</div>
<div id="picture-set-3" style="display:none;">
<img src="images/5.jpg" align=left width=1000>
</div>
</div>

您想要使用 clearInterval 删除悬停时的间隔，然后在关闭悬停功能中替换它:

$('#slide-show-overall').hover(function(ev){
    clearInterval(timer);
}, function(ev){
    timer = setInterval( showDiv, 5000);
});
