I have initialized a static array as shown below:
country["0"]=[USA];
state[country[0][0]]=[["NewYork","NY"],["Ohio,"Oh"]]
for (var i = 0; i < state[country[0][0]].length; i++) {
var key = state[country[0][0]] [i][0];
var value = state[country[0][0]] [i][1];
}
In the above loop, I am able to access the keys of states like NewYork and Ohio. Can someone guide me on how to retrieve the values "NY" and "OH"?
let result = state[country[0][0]] [i][1];
Your code contains a few mistakes that need to be addressed. Let's assume the variable country holds a list of countries and the variable state stores information about states within each country...
country = ["USA"];
state = {"USA": [["NewYork", "NY"], ["Ohio", "OH"]] };
for (var i = 0; i < state[country[0]].length; i++) {
var key = state[country[0]][i][0];
var value = state[country[0]][i][1];
}
Oops, looks like there's a typo here
state[country[0][0]] = [["NewYork","NY"],["Ohio", "Oh"]]
To retrieve ["NY", "Oh"], you can use the following code snippet:
for (var i = 0; i < state[country[0][0]].length; i++) {
var key = state[country[0][0]][i][0];
var value = state[country[0][0]][i][1];
}
