I have a long array like this:

Who contains almost 2000 objects. How can I export this to text and use it in another javascript file/project?

• javascript
• jquery
• arrays

• Write it to a file on the server with PHP? – Jeremy Thille Commented Apr 9, 2015 at 9:23

Try like this

var array = [{
    x: 0,
    y: 0
}];
var a = document.body.appendChild(
    document.createElement("a")
);
a.download = "export.txt";
a.href = "data:text/plain;base64," + btoa(JSON.stringify(array));
a.innerHTML = "download example text";

Use JSON.stringify(array). This will return you with a string that you can save somewhere, say, on the server, and then re-use it as javascript array again.

To send the string to a server, you can use jQuery's $.ajax function. To retrieve it back, you can again use the $.ajax function, but it might be a good idea to also specify that the result from server is of type json. To do that, specify dataType to be json in the function.

Stringify it and copy it to another JavaScript project

JSON.stringify(array);
