Extract number from string JavaScript

Question

Does anyone know a way to extract numbers from a string in JavaScript?

Example:

1 banana + 1 pineapple + 3 oranges

My intent is to have the result in an array or JSON or something else.

Result:

[1,1,3]

Answer 1

var result= "1 banana + 1 pineapple + 3 oranges";
result.match(/[0-9]+/g)

Answer 2

Using String.prototype.match() and parseInt() :

 const s = "1 banana + 1 pineapple + 3 oranges"; const result = (s.match(/\\d+/g) || []).map(n => parseInt(n)); console.log(result);

Answer 3

Use this regex

• / -> start
• \\d+ -> digit
• /g -> end and g for global match

 var str="1 banana + 1 pineapple + 3 oranges",mats=[]; str.match(/\\d+/g).forEach(function(i,j){mats[j]=parseInt(i);}); console.log(mats);
