I am trying to send a javascript object to PHP using JSON.stringify and I cannot find a solution. Here`s an example of what I have:
var small_array = [],
final_array = [];
small_array["ok"] = "ok";
small_array["not_ok"] = "not_ok";
final_array.push(small_array);
console.log(JSON.stringify(final_array));
The output is "[[]]"
Any guidance on this one? Thanks
You're adding non-array-entry properties to the array. That's fine in JavaScript, but JSON doesn't have the notion of non-array-entry properties in an array (JSON arrays are just ordered sequences, whereas in JavaScript arrays are fully-fledged objects that provide special treatment to certain kinds of properties — more in my [ancient] blog post A Myth of Arrays).
For those property names (keys), you'd want a plain object, not an array:
var obj = {}, // Note {}, not []
final_array = [];
obj["ok"] = "ok";
obj["not_ok"] = "not_ok";
final_array.push(obj);
console.log(JSON.stringify(final_array));
[ancient] lol :)
There are no associative arrays in javascript. They are called objects:
const smallObject = {
ok: "not ok",
not_ok: "ok"
};
const finalArray = [smallObject];
console.log(JSON.stringify(finalArray));
Objects in javacript are defined like this var obj = {}
var small_array = {},
final_array = {};
small_array["ok"] = "ok";
small_array["not_ok"] = "not_ok";
final_array = (small_array);
console.log(JSON.stringify(final_array));
