Find specific occurrence and parse it into an array.

Question

I have a bunch of disorganized information in a var, and I want to:

1. Loop over the info and extract all the numbers that are preceded with a currency symbol $, or the word Price.

2. Input all these occurrences into an array

So far I have found a way to find occurrence of the dollar sign, but I have no idea on the rest of the steps I have to take.

var str = "My father/taughtme$500ho<div>wtoPrice:700throwabaseball$30";
var getCount=function(str){
    return (str.match(/$/g) || []).length;
};
alert(getCount(str));

Appreciate any help, and sorry if I am not detailed enough.

Answer 1

You can accomplish this with .match and a regular expression.

var data = "My father/taughtme$500ho<div>wtoPrice:700throwabaseball$30";

var prices = (data.match(/[\$|price:]\d+/gi) || []).map(function(m) {
  //Convert each match to a number
  return +m.substring(1);
});

document.write(prices);
console.log(prices);

The expression /[\$|price:]\d+/gi matches all numbers that start with $ or price:, in any case. Then, use map to convert each match to a number, and chop off the : or $.
