Unraveling JSON data retrieved from a MySQL query

After successfully encoding a MySQL result from PHP into JSON, I am now faced with the task of decoding it using JavaScript. Let's assume that my string returned is:

[{"0":"x","1":"z"},{"0":"xs","1":"zz"}]

I would appreciate some guidance on how to extract the value of a specific row and column from this data. For example, obtaining the value of "0" from the second row.

UPDATE:

My apologies for reaching out, friends. It turns out that my error was due to overlooking the fact that the data type was originally a string. Using JSON.parse(data) resolved the issue for me.

Answer №1

const info = [{"0":"a","1":"b"},{"0":"aa","1":"bb"}];
alert(info[1]["0"]);

displays the value of aa

The structure of [] signifies an array, with each {} representing an element within that array. Inside each object are attributes which can be accessed using their identifiers. In this example, we are retrieving the attribute with identifier 0.

Answer №2

What is the purpose of creating objects? It is not recommended to label attributes with numbers as it results in poor coding standards.

Considering that these are clearly arrays, a better approach would be:

var array = [["x","z"],["xs","zz"]]

Subsequently,

array[1][0] will return "xs"
