ElementUI多选框组el-checkbox-group，重新勾选时不希望数组顺序被打乱

1、重新排序

?

1 2 3 4 5

let checkboxList=['a','b','c'] let checkList=['c','a'] let newCheckLIst=checkList.sort((a, b) => { return checkboxList.indexOf(a) - checkboxList.indexOf(b) })

　　

2、如果是没法排序的汉字之类的，就只能用checkbox的数组进行filter，挨个去过滤是否在已选的数组中

?

1 2 3

let checkboxList=['a','b','c'] let checkList=['c','a'] const newCheckLIst = checkboxList.filter(item => checkList.includes(item))
