What is the correct Underscore.js way to create a new object called items that consists of each of the item arrays. Where I could then make a POST of each item.name in one call?
var items = [];
item = [{
name: "item1",
desc: "this is a description of item 1",
qty: 1
},{
name: "item2",
desc: "this is a description of item 2",
qty: 5
},{
name: "item3",
desc: "this is a description of item 3",
qty: 3
}];
items.push(item);
If I understand the question correctly you want to convert an array of items to an object where each key is the name of the object
e.g.
{
item1: {
name: "item1",
desc: "this is a description of item 1",
qty: 1
},
item2: { ... },
item3: { ... },
}
If that's the case then you could use the object function that takes two parameters; the first being the list of property names and the second a list of the values:
var items = [{
name: "item1",
desc: "this is a description of item 1",
qty: 1
},{
name: "item2",
desc: "this is a description of item 2",
qty: 5
},{
name: "item3",
desc: "this is a description of item 3",
qty: 3
}
];
var itemsAsAnObject = _.object( _.pluck(items,'name'), items)
{ ... }object syntax instead (i.e.item = { name: "item1", desc: "this is... }. If you're going to create the objects this way, you'll also want to callitems.push(item);after each object literal. Otherwise you're never going to have anything in your array asitemhas not been defined at the time of reference.itemsthat contains theitemobjects. If you wantitemsto be an object and eachitemto be an object, you'll need to determine what the names of the three subobjects will be.
