现在我的问题是我想在右下角显示一个名称，只显示该名称的一个弹出框。如果用户点击弹出框以外的任何位置，弹出框应该关闭。
我该如何实现这个目标？
NB ：我没有创建jsfiddle，因为我不知道如何制作它，但如果你只是在你的机器上创建一个HTML文件并复制粘贴我的代码，您将能够在浏览器中运行代码。

使用弹出窗口绑定以下事件。
$(':selector').bind({
mouseover : function(){
mouseIn = 1;
},
mouseout : function(){
mouseIn = 0;
},
click : function(){
mouseIn = 1;
}
});
$(document).click(function(){
if($(":selector").is(":focus")){
mouseIn == 1;
};
if(mouseIn == 0){
$(':selector').slideUp();
}
});
