Return only numbers from string

Question

I have a value in Javascript as

var input = \"Rs. 6,67,000\"

How can I get only the numerical values ?

Result: 6

Answer 1

var input = "Rs. 6,67,000";

input = input.replace("Rs. ", "");

//loop through string and replace all commas
while (input.indexOf(",") !== -1) {
    input = input.replace(",","");
}
