Extract a number from a string (JavaScript)

Question

I have a string in JavaScript like #box2 and I just want the 2 from it.

I tried:

var thestring = $(this).attr(\'href\');
var          


        

Answer 1

changeStrangeDate(dateString: string) {
var sum = 0;
var numbers = dateString.match(/\d+/g);
if (numbers.length > 1) {
  numbers.forEach(element => {
    sum += parseInt(element);
  }
  );
}
console.log(new Date(sum).toDateString());
return new Date(sum).toUTCString();

}

You can do it like that and then call function where you need, with parameter.

this.changeStrangeDate('/Date(1551401820000-0100)/');
