Pattern

regexJS
^\$?\d{1,3}(,\d{3})*(\.\d{2})?$

JavaScript / ECMAScript code

jsJavaScript
const re = new RegExp("^\\$?\\d{1,3}(,\\d{3})*(\\.\\d{2})?$", "");
const input = "$1,234.56";
const matches = [...input.matchAll(re)];
console.log(matches.map(m => m[0]));

Uses `String.prototype.matchAll` for global iteration (Node 12+ / all modern browsers).

How the pattern works

`^\$?` optional dollar sign. `\d{1,3}(,\d{3})*` matches the integer part with optional comma-separated thousands. `(\.\d{2})?` optional cents.
