Maybe the problems is an event called "ondblclick" for internet explorer. 也许问题出在互联网浏览器上，这是一个称为“ ondblclick”的事件。
You can try the solution from this question to remove that event: 您可以尝试从以下问题中解决问题，以删除该事件：

There is definitely a latency issue in Internet Explorer 8. Somewhat in line with what Oscar stated in his answer, the dblclick event may be eating up some of the clicks. Internet Explorer 8中肯定存在延迟问题。与Oscar在他的回答中所说的有些dblclick ， dblclick事件可能正在吞噬某些点击。 If this were the case, we could expect that incrementing during that even would eradicate the problem. 如果是这种情况，我们可以期望在此期间增加甚至可以消除问题。 Sure enough, that's what we find when we handle that event as well. 当然，这也是我们处理该事件时发现的。
(function () {
"use strict";
var clicks = 0,
result = document.getElementsByTagName( "label" )[0],
button = document.getElementsByTagName( "button" )[0];
if ( button.addEventListener ) {
button.addEventListener( "click", increment );
} else if ( button.attachEvent ) {
button.attachEvent( "onclick", increment );
button.attachEvent( "ondblclick", increment );
}
function increment () {
result.innerHTML = ++clicks;
}
}());
The problem doesn't appear to exist with versions of IE that support the addEventListener method (Internet Explorer 9 and up). 支持addEventListener方法的IE版本（Internet Explorer 9及更高版本）似乎不存在此问题。 As a result, we really only appear to need the double-binding in version 8 and below. 结果，我们真的只需要在版本8和更低版本中进行双重绑定。
