如何通过 JavaScript 从数组创建哈希？

Question

I've an Array, [name1-name1@email.com,name2-name2@email.com] .

I want to create a new Hash from this Array. The result should be:

users: [
        {
           name: "name1",
           email: "name1@email.com"
        },
        {
           name: "name2",
           email:"name2@email.com
        }
       ]

Answer 1

In JavaScript, you could use Array#map and String#split and objects for the result.

This solution features a - as the separator. This might not work for all emails, because - is an allowed character for emails. In this case, I suggest to use a different separator, like | .

 var data = ['name1-name1@email.com', 'name2-name2@email.com'], users = data.map(function (a) { var aa = a.split('-'); return { name: aa[0], email: aa[1] }; }); console.log(users);

Answer 2

var arr = ['name1-name1@email.com','name2-name2@email.com'];
arr = arr.map(node => {
    var ta = node.split('-');
    return {
        name : ta[0],
        email : ta[1]
    }
});

var users = {users : arr};

I do not know the difficulty ...

Answer 3

 var names = ['name1-name1@email.com','name2-name2@email.com']; var users = []; for (var i = 0; i < names.length; i++) { var splitted = names[i].split('-'); users.push({ name: splitted[0], email: splitted[1] }) }; console.log(users);

Answer 4

试试这个。

data = ['name1-name1@email.com', 'name2-name2@email.com'] result = data.map{|s| {name: s.split('-')[0], email: s.split('-')[1]} }
