str.match - how to remove $ and show digital value only?

Question

Here is my code value = str.match(/$(\d+)/);

For example 1: HK$999 Display Result = 999

For example 2: HK$1,999.20 Display result = 1 (I would not want this result)

How can show the example 2 = 1999

Thank you all ^_^

Answer 1

This code should work fine first remove all the unnecessary comas from the string then select all the numbers before "."

var ragex = /(\d+)/g;

let str = "HR999";
str = "HK$1,999.20"
str = str.replace(/(,)/, '')

let res = str.match(ragex)[0];

the result will be at first index in the array

if you want numbers including.

use this ragex

var ragex = /\d+.\d+/g;
