Question

I have a form that sends money value e.g

<input type="text" name="amount" value="N50,000.00 NGN" />
<input type="button" value="submit">

I want to remove all characters in the amount field leaving only the numbers in this format;

<input type="text" name="amount" value="50000" />
<input type="button" value="submit">

what is the best method to do this with javascript?

Answer 1

first think you want to do is to strip the string or value from numbers using something like this

<input type="text" name="amount" value="N50,000.00 NGN" />
<input type="button" value="submit">



var amount =  $('input[name=amount]').val().replace(/[A-Za-z$-]/g, "");
   amount=amount.replace(",", "");
   amount=parseInt(amount).toFixed(0);

here is a working example
