css - 如何控制鼠标事件？当处于down时会触发其他效果，而up的时候则会取消所有效果?

Question

点击的时候，按钮会变橙色，松开变回白色。处于点击状态时，离开会变回白色，进去又为橙色。
但松开后，离开和进入的效果被保存到css了。
怎么让完成一次点击事件后，无效掉进入与退出的效果。

    $(".bottom .button").on({
        mousedown:function(){
            $(this).css("background-color","#FD9917").css("color","white")
                .on({
                    mouseenter:function(){
                        $(this).css("background-color","#FD9917").css("color","white")},
                    mouseleave:function(){
                        $(this).css("background-color","white").css("color","black")}
                })
        },
        mouseup:function(){
            $(this).css("background-color","white").css("color","black")
        }
    })

First of all, the poster needs to understand, 事件的绑定没有嵌套，不嵌套的.
Once an event is bound, it will always be valid and fixed.
Unless unbound.
The following method also works.

var flag = 0;
 $(".bottom .button").on({
        mousedown:function(){
            $(this).css("background-color","#FD9917").css("color","white");
            flag = 1;
        },
        mouseup:function(){
            $(this).css("background-color","white").css("color","black");
            flag = 0;
        },
         mouseenter:function(){
                 if (flag==1)$(this).css("background-color","#FD9917").css("color","white");
         },
         mouseleave:function(){
                       if (flag==1)$(this).css("background-color","white").css("color","black");
         }
    })

First of all, I suggest you write css to achieve this effect

If you insist on writing js:
Write it into css, and then addClass class name in the event
After the event is executed, there will be a callback event, and in the callback event removeClass

Answer 3

You can use css pseudo-classes to achieve
a:link { } / Unvisited links /
a:visited { } / Visited links /
a:hover { } / When the mouse is hovering over the link /
a:active { } / The selected link /

Answer 4

Isn’t it very easy to achieve the effect you want using CSS pseudo-classes? As for what you said, after releasing, the effects of leaving and entering are saved to css. What is the requirement for this?
