Jquery mousedown vs click
提问by xhallix
today I discovered something that was quite confusing for me. I just tried to hide s.th via jquery... first I tried to use this
今天我发现了一些令我困惑的事情。我只是试图通过 jquery 隐藏 s.th ......首先我尝试使用它
$(".specificdiv li:nth-child(3)").click(function(){
$(".anotherdiv").hide();
})
....but it does not work.
....但它不起作用。
After a time I tried it this way:
一段时间后，我以这种方式尝试过：
$(".specificdiv li:nth-child(3)").mousedown(function(){
$(".anotherdiv").hide();
})
Can anyone explain me why mousedown works instead of click? Would be great to find out
谁能解释一下为什么 mousedown 起作用而不是单击？很高兴知道

Possible reasons:
可能的原因：
- The event
mousedownexecutes beforeclick, so first come first serve. - The element might have already a
clickevent, which prevents this from happening, say that function executes first and it has areturn falsestatement in it.
- 事件
mousedown在之前执行click，所以先到先得。 - 该元素可能已经有一个
click事件，这可以防止这种情况发生，假设该函数首先执行并且其中有一个return false语句。
Now since you are using mousedown, which is not assigned for this element, it doesn't have any conflicts. This may bea reason, because you didn't post the full code. Feel free to correct. :)
现在，由于您使用的mousedown是未为此元素分配的 ，因此它没有任何冲突。这可能是一个原因，因为您没有发布完整的代码。随意纠正。:)
On a smaller note, you have $(".anotherdiv").hide();in the first code and $(".another").hide();in the second code, missing the divin the class. Is that a problem?
在较小的说明中，您$(".anotherdiv").hide();在第一个代码和$(".another").hide();第二个代码中都缺少div类中的 。那是问题吗？

Actually the mousedown event is triggered when you push down the button, even you don't let the button up. The click is like the mouseup, when you let the button go up.
实际上，当您按下按钮时会触发 mousedown 事件，即使您不让按钮向上。当您让按钮向上时，点击就像鼠标向上。
In your code you have: ".anotherdiv" and ".another" could it be your error?
在您的代码中，您有：“.anotherdiv”和“.another”可能是您的错误吗？
