Firefox与contextmenu事件同时触发click事件 [英] Firefox fires click event at the same time with contextmenu event
问题描述
接下来的代码将触发事件记录在窗口对象上( FIDDLE ):
Next code logs the fired events on window object (FIDDLE):
var logEvent = (function() {
var count = 1,
timer = 0,
buffer = function() {
clearTimeout(timer)
timer = setTimeout(function() {
count++
}, 30)
}
return function(type, e) {
buffer();
console.log(count + '. ------- ' + type + ' ------')
console.log('type: ' + e.type)
console.log('button: ' + e.button)
console.log('detail: ' + e.detail)
}
})()
window.addEventListener('click', function(e) {
logEvent('CLICK', e)
})
window.addEventListener('contextmenu', function(e) {
logEvent('CONTEXTMENU', e)
})
<body>
<div>
Click here
</div>
</body>
例如，如果我右键单击body元素，则将在控制台上获得下一次登录:
If I right click on the body element for example, I'll get next log on console:

我不知道Firefox发生了什么，也许浏览器或操作系统的配置配置不正确.您是否有同样的问题，我该如何解决?
I don't know what's going on with Firefox, maybe browsers or operational systems configuration configured improperly. Did you have same problems, how can I fix it?
推荐答案
它也在我的firefox上发生.
It happens on my firefox too.
这是一个已注册的错误，请参见 https://bugzilla.mozilla.org/show_bug .cgi?id = 184051

您可以通过检查点击处理程序中的e.button值来解决此问题.
You can go around it by checking e.button value in the click handler.
window.addEventListener('click', function(e) {
//when e.button==2, it's a right click, when 0, it's a left click
logEvent('CLICK.' + e.button, e);
if(e.button===2){
//do context menu stuff
}
})
