如何将一堆数组转换为单个对象？

Question

Here is what im doing:

onClick, grab details immediate subnodes and publish it on html. Status = DONE // This works well

NOW, I am using a bunch of arrays to get this done.

node.eachSubnode(function(node) {
                   title[title.length] = node.name; // This is what i want to modify
                   data[data.length] = node.data; // This is what i want to modify
                });

Here is how they look currently:

title = ['Coffee', 'Tea'];
data = ["Americans", "Britishers"]; // i use a loop to iterate through these arrays and append to html.

Here is what i want it to be:

var preference = {
title: 'Coffee',
data: 'Americans'
},
{
title: 'Tea',
data: 'Americans
}

I want to create this using the node.eachSubnode loop.

Answer 1

I'm not sure if I understood correctly, but I think this is what you want:

var preferences = [];

node.eachSubnode(function(node) {
    preferences.push({
        title: node.name,
        data: node.data.germ
    });
});

You cannot create an object that looks exactly like that, I think you need an array with objects. Assuming your node is an array with the length property, this method is the fastest .

var preference = new Array(node.length||0), i = 0;
node.eachSubnode(function(node) {
    preference[i++] = {
        title: node.name,
        data: node.data.germ
    };
});
