I want to define an associative array like this
var theVar = [
{ "100", [0, 1, 2] },
{ "101", [3, 4, 5] }
]
Essentially I want to be able to access an array of three numbers by specifying the custom index.
However, no matter what I try I cannot make it work.
I know I can define it as:
theVar["100"] = [0, 1, 2];
theVar["101"] = [1, 2, 3];
But I am setting this somewhere else and I'd prefer to be able to set it in a single statement.
theVar = {
"100": [0, 1, 2],
"101": [3, 4, 5]
}
might do the trick. You can then access using theVar["101"]
(or theVar[101]
for that matter).
(As var
is also a keyword in JavaScript, using it as a variable name is very likely to cause problems.)
Have a look at the JSON syntax, I think It could inspire the building of your data structures in a way that will be flexible, correct and complex as you want.
This page has a lot of information and example that are helpful for you.
For instance look at this:
var employees = { "accounting" : [ // accounting is an array in employees.
{ "firstName" : "John", // First element
"lastName" : "Doe",
"age" : 23 },
{ "firstName" : "Mary", // Second Element
"lastName" : "Smith",
"age" : 32 }
], // End "accounting" array.
"sales" : [ // Sales is another array in employees.
{ "firstName" : "Sally", // First Element
"lastName" : "Green",
"age" : 27 },
{ "firstName" : "Jim", // Second Element
"lastName" : "Galley",
"age" : 41 }
] // End "sales" Array.
} // End Employees
