A jquery plug-in every day-do date plug-in 3
Do date plugin 3
It’s almost done, and the selection part accurate to hh-mm-ss will not be done. Anyway, just have an idea.
The effect is as follows
Code part
*{
margin: 0px;
padding: 0px;
user-select: none;
}
.rel{
width: 210px;
height: 240px;
position: absolute;
border: 1px solid lightgray;
box-shadow: 0 0 1px 0px black;
}
.item{
font-size: 12px;
width: 30px;
height: 30px;
display: flex;
justify-content: center;
align-items: center;
float:left;
color: black;
cursor: pointer;
}
.item:hover{
opacity: 0.9;
background-color: gray;
color: white;
}
.item.head{
background-color: gray;
color: white;
}
.item.prev,.item.next{
color: lightgray;
}
.item.check{
background-color: #2ecc71!important;
color: white!important;
}
.item.tool{
font-weight: bold;
position: absolute;
bottom: 0;
}
.left{
left: 30px;
}
.val{
left: 60px;
}
.right{
left: 150px;
}
.rright{
left: 180px;
}
.val{
width: 90px;
pointer-events: none;
}

Idea explanation
- Look at the notes, it feels like there is nothing to say
- Anyway, to do a thing, you must understand its actions, and then combine it with your own understanding to achieve it. Of course, you still need to understand your programming tools.
