How to convert string from textbox into a number using javascript?

I have a textbox with input value of 20,466,000.00 . I want to return only the value of 20466000 without a comma and a decimal point. I tried the following :

// Get value
var nca_balance = $("#nca-balance").text();
var nca_amount = parseInt(nca_balance.replace(",", ""),10);

alert(nca_amount);

But it only returns the value of 20466 ? Why ? My expected result must be 20466000. Please help with my code. Thanks

You have to use regular expression instead of replace function because replace function will replace only first matching character.

nca_balance = "20,466,000.00";
var nca_amount = parseInt(nca_balance.replace(/,/g, ''));
alert(nca_amount);

Regular expression /,/g will replace all comma with your provided character globally.

Because replace is replacing the first comma by default use g as global option in replace regular expression /,/g like,

var nca_balance = $("#nca-balance").text();
var nca_amount = parseInt(nca_balance.replace(/,/g, ""),10);
alert(nca_amount);


    var nca_balance = $("#nca-balance").text();
    var nca_amount = parseInt(nca_balance.replace(/,/g, ""), 10);
    alert(nca_amount);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id="nca-balance">20,466,000.00<span>

How about this one:

parseInt("20,466,000.00".replace(/,/g, ""), 10)
