What is the process for extracting an object from an array?

As a newcomer to jQuery, I've encountered an issue that has me stuck. My problem lies in accessing an array within an object. Here's the structure of my object as shown during debugging:

 
   cache:object 
   0001-:Array[2]
         0:value1,
         1:value2
   _prto_:object

I am looking to access value1 and value2 from the 0001- array within that object. Is there a direct way to do this without using $.each to loop through it? Any guidance on this matter would be greatly appreciated.

Answer №1

To access it, make sure to use bracket notation because the keys start with numbers.

cache['0001-'][0] //first element
cache['0001-'][1] //second element

Here's a workaround for your specific requirement:

var cache = {'0001-' : [0,1]};
var xKeys = Object.keys(cache);

console.log(xObj[xKeys[0]][0]);
console.log(xObj[xKeys[0]][1]);
