Remove square brackets at beginning and ending using Undersore or Javascript

问题

I trying to remove array square bracket at beginning and end.

EX: [['moe', 30], ['larry', 40], ['curly', 50]]

Need: ['moe', 30], ['larry', 40], ['curly', 50]

回答1:

If it is a string you can use the substring or slice method like this:

var yourString = "[['moe', 30], ['larry', 40], ['curly', 50]]";
// using substring
var result = yourString.substring(1, yourString.length-1);
console.log(result);
// using slice
var result2 = yourString.slice(1, -1);
console.log(result2);
