elementUI 实现 checekbox 全选


写在前面

为什么写这个呢?两个原因,一个是自己用到了,另一个是压根没人写,我不知道是太简单了懒得写还是很多人都忘记了,不过我看网上找demo的还挺多的,而且天下文章一般抄,都不对还在那不停的抄,我也是醉了,没一点办法,罢了罢了,自己写吧

官方DEMO

官方全选DEMO
全选这里就不实现了,很简单,官方给的有,实现反选
这里使用的还是官方的demo,只是添加了一个反选的函数,所以使用的时候先看官方demo源码

<el-checkbox :indeterminate="isIndeterminate" v-model="Reverseflg" @change="Reverse">反选</el-checkbox>
//反选
Reverse(){

//记录当前被选中的值给一个空数组
let idx;//记录当前是不是存在这个值
let currArr = []; //记录当前的选择的数组
for(let item of this.cities){

idx = this.checkedCities.includes(item) //如果不存在当前的值就将该值放到最新的空数组里
if(!idx){

currArr.push(item)
}
}
this.checkedCities = currArr
}

input 输入空格使用label分割

这个DEMO是我看的这篇文章,根据自己的需求改了一下,感谢这位同志的文章。
