Question

I have an array (it might be an object too, I don’t know what I’m talking about):

grid.columns[0].text
grid.columns[1].text
grid.columns[2].text

And so on. I want to convert it into JSON. I’ve tried to use JSON.stringify(grid.columns.text) but it didn’t work: it gives null.

Answer 1

Try with

JSON.stringify(grid.columns.map(function(item) {
    return item.text;
}));
// ["value of text 0", "value of text 1",...]

Alternatively

JSON.stringify(grid.columns.map(function(item) {
    return {text:item.text};
}));
// [{"text":"value of text 0"},{"text":"value of text 1"},..]
