What would be the way to count the items of a json response with this structure:
[['dato', 'dato', 'dato'], ['dato', 'dato', 'dato']]
and so on.
I know that using this function count = Object.keys(res).length; you can count the items of each element, I want to count all the items of all the elements.
Thanks for your help.
That structure is an array of arrangements; an option would be to flatten that array using [].concat.apply([], elArray) and then get its length.
With flattening, I mean converting (temporarily and for calculation) this structure:
[['dato', 'dato', 'dato'], ['dato', 'dato', 'dato']]
in this other:
['dato', 'dato', 'dato', 'dato', 'dato', 'dato']
Salu2, an example:
var datos = [['dato', 'dato', 'dato'], ['dato', 'dato', 'dato']]
console.log(
[].concat.apply([], datos).length
)var data = /* Su JSON sintetizado aquí */
var numberOfElements = data.res.length;
var o = JSON.parse(res);
alert(o.features.length);
