javascript – Convert array to string while preserving brackets
I have a multidimensional array that looks like this:
var myArray =[[1,2,3,4,5],
[1,2,3,4,5],
[1,2,3,4,5],
[1,2,3,4,5]];
I wish to put its contents in a div (so that one can easily copy and paste).
However, when I do
var x = document.getElementById("result");
x.textContent = myArray;
I just get
1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5
Use JSON.stringify():
var x = document.getElementById("result");
x.textContent = JSON.stringify( myArray );
You can either use JSON.stringify or custom joining like this
console.log("[[" + myArray.join("],[") + "]]");
# [[1,2,3,4,5],[1,2,3,4,5],[1,2,3,4,5],[1,2,3,4,5]]
console.log(JSON.stringify(myArray));
# [[1,2,3,4,5],[1,2,3,4,5],[1,2,3,4,5],[1,2,3,4,5]]
