Tips for eliminating strings containing numbers and special characters with javascript regular expressions

let str = "[Account0].&[1]+[Account1].&[2]+[Account2].&[3]+[Account3].&[4]";
let numArray = str.match(/(\d+)/gi);
alert(numArray.join(','));

The resulting numbers are: 0,1,1,2,2,3,3,4

I am looking to remove all strings with numbers and special characters.

Can anyone help with a solution to get the output: 1,2,3,4

Thank you,

Rajasekhar

Answer №1

A simple and efficient answer could be

let numList = phrase.match(/\[\d+\]/gi); // numList = ['[1]', '[2]', '[3]', '[4]'];
console.log(numList.join(',').replace(/[\[\]]/g, ''));
