Extract number from string javascript

Question

Is anyone know a way to extract numbers from a string in Javascript ?

Example: 1 banana + 1 pineapple + 3 oranges

My purpose is to have the result in a 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():

let s = "1 banana + 1 pineapple + 3 oranges";
let 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);
