应用场景：将对象数组根据指派的数组内容进行排序，未指定的对象按照原始顺序。 

const nodeData_ = [
    {account:'a',node:1},
    {account:'b',node:2},
    {account:'c',node:3},
    {account:'d',node:4},
    {account:'e',node:5},
    {account:'f',node:6}
]
const sortInfo = ['f','c','b']
nodeData_.sort((a, b) => {
    if (sortInfo.indexOf(a.account) === -1 && sortInfo.indexOf(b.account) === -1) {
        return 1
    } else if (sortInfo.indexOf(a.account) !== -1 && sortInfo.indexOf(b.account) === -1) {
        return -1
    } else if (sortInfo.indexOf(a.account) === -1 && sortInfo.indexOf(b.account) !== -1) {
        return 1
    }
    return sortInfo.indexOf(a.account) - sortInfo.indexOf(b.account)
})
console.log(nodeData_)

输出结果：

0: {account: "f", node: 6}
1: {account: "c", node: 3}
2: {account: "b", node: 2}
3: {account: "a", node: 1}
4: {account: "d", node: 4}
5: {account: "e", node: 5}
