Each Tab normal state displays one picture, while the selected state displays another picture?

topic description

I can make it possible to display a different picture on each tab, but how can I go one step further so that each Tab displays one picture in its normal state and another picture in the selected state?

sources of topics and their own ideas

when I meet this requirement when I am working on a project again, I have no idea

Replace the picture in the url of img when the

event is triggered;
1. Two-way binding directly manipulates data
2. Native js can use getAttribute to get url and assign a value

each tab tag has a selected state or not. According to different states, render different images

selected tab plus an active class, define the active style of each tab in css, and set the icon of the selected state in active:after

. 
<li class="active">
    <img src="img/icon/data.png" class="icon_off" alt="">  
    <img src="img/icon/data_on.png" class="icon_on" alt="">   
</li>

.icon_off {
   display: block;
}
.icon_on {
   display: none; 
}

.active .icon_off {
    display: none;
}

.active .icon_on {
    display: block;
}

this is the way I handled it before, and I hope it will be helpful
