If I understand correctly, list in this code is an array that consists of objects . I want to access temp in the main object and thought main.temp would do the trick, but I get an error message stating it's undefined. Alternatively I've tried list[1].main.temp
. What is the correct way to access nested arrays like this?
What is the correct way to access nested arrays like this?
First of all these aren't nested arrays, but array of objects instead and in an array
we access the items by index, and in objects
we access them(entries) by keys.
So in your case list[0]
is an object
where list[0].dt
is an entry and list[0].main
is another entry of the object
, so dt
isn't at index 0
like you mentioned in your comment.
And to access all your array main.temp
properties you need to loop throught the array
elements using one of the Array
built-in methods or just a for loop
, because using static indexes in list[1].main.temp
will just get the temp
property of the firts element in the array and may throw an exception if this index is higner than the array.length
.
This is how should be your code:
for(var i=0; i<list.length; i++){
console.log(list[i].main.temp);
}
