a.b.c.d 转 a:{b:{c:123}} 支持对象 数组

方法中用到 lodash.js 的一个 merge合并对象方法

let arr = [
    {
        name:'a[0].b.c',
        value:123
    },{
        name:'a[0].b.a',
        value:123
    },{
        name:'a[1].a.a',
        value:456
    },{
        name:'c.d.a',
        value:789
    },{
        name:'b.c.c[0]',
        value:789
    },{
        name:'b.a[1].c',
        value:789
    },{
        name:'b.a[1].d',
        value:456
    },{
        name:'b.a[0].c',
        value:789
    }
]
let obj = {}
arr.forEach(e=>{
    let a = `${e.name}`.split('.');
    let b = a[0].includes('[')?[]:{};
    if(a[0].includes('[')){
        let t = a[0].match(/\[(\S*)]/)[1];
        let t1 = a[0].match(/(\S*)\[/)[1];
        if(!obj.hasOwnProperty(t1)) obj[t1] = [];
        if(!obj[t1][t]){
            obj[t1][t] = getObj(a,b,e)
        }else{
            obj[t1][t] = _.merge(obj[t1][t],getObj(a,b,e))    
        }
    }else{
        if(!obj.hasOwnProperty(a[0])){
            obj[a[0]] = getObj(a,b,e)
        }else{
            obj[a[0]] = _.merge(obj[a[0]],getObj(a,b,e))
        }
    }
});
function getObj(arr,type,e){
    return arr.reduceRight((p,c,i)=>{
        if(!i) return p
        if(c.includes('[')){
            let t = c.match(/\[(\S*)]/)[1];
            let t1 = c.match(/(\S*)\[/)[1];
            let ta = Array(t+1).fill()
            ta[t] = ((arr.length - 1)==i)? e.value:p
            return {[t1]:ta}
        }else{
            
            if((arr.length - 1)==i) return {[c]:e.value}
            return {[c]:p}
        }
    },type);
}
console.log(obj)
