Taro accordion component implements dynamic single component drop-down box
Let’s take a look at the effect before the changes.
点其中一个下拉框其他的一起展开和关闭。
The style you want to change to
点其中一个只管这个组件的展开与关闭
The code is very simple and I will give it to you directly, so I won’t go into details.
Main code js .
// An highlighted block
handleClick (id, value) {
var a = [this.state.ress]
for (var i=0;i<this.state.ress;i++){
if(i==id){
a[i]=value
}else{
a[i]=false
}
}
this.setState({
open:a
})
}
constructor(props){
super(props)
this.state={
// open: false,
current: 0,
findList:[],
open: [],
ress: '',
}
}
//初始化列表
init(){
var findList=[
{
name: '番茄A'},
{
name: '番茄B'},
{
name: '番茄C'}
]
this.setState({
findList: findList,
//讲数组总条数赋值
ress: findList.length
})
}
componentDidMount () {
this.init()
}
{
findList.map((obj,index) => {
return(
<AtAccordion
open={
this.state.open[index]}
onClick={
this.handleClick.bind(this,index)}
title={
obj.name}
isAnimation
>
<AtTabBar
tabList={
[
{
title: '种', id:1, image: 'https://img12.360buyimg.com/jdphoto/s72x72_jfs/t6160/14/2008729947/2754/7d512a86/595c3aeeNa89ddf71.png'},

onClick={
this.handleClick1.bind(this)}
current={
this.state.current}

</AtAccordion>
)
})
}
The above is the main code. Below I will give you all the code. It includes some clicks on the component buttons in the drop-down box, which you can remove.
