Tip: if you use layui, you'd better not use vue.js,layui to have your own way of dealing with forms. However, if you want to use the vue.set () method to modify the worthwhile words, you will have to traverse the array once:

var arr = [{ id:1,name:[{ value:"123"}]}];
arr.map((item) => {
    Vue.set(item.name,value,'456');
})
//splice()
arr.splice(0,1,{ name:[{ value:"456"}]});
//

use Vue.$set
