Question

I have an array as follows. How would I retrieve the value of a specific key and put that value in a variable?

var obj = {"one":"1","two":"3","three":"5","four":"1","five":"6"};

So for instance if I want to get the value of “three” how would I do it in javascript or jQuery?

Answer 1

You can do this via dot or bracket notation, like this:

var myVariable = obj.three;
//or:
var myVariable = obj["three"];

In the second example "three" could be a string in another variable, which is probably what you’re after. Also, for clarity what you have is just an object, not an array 🙂
