How can I correctly format currency using jquery?

Question

I do not need a mask, but I need something that will format currency(in all browsers) and not allow for any letters or special char\'s to be typed. Thanks for the help

Try regexp currency with jQuery (no plugin):

$(document).ready(function(){
  $('#test').click(function() {
    TESTCURRENCY = $('#value').val().toString().match(/(?=[\s\d])(?:\s\.|\d+(?:[.]\d+)*)/gmi);
    if (TESTCURRENCY.length <= 1) {
      $('#valueshow').val(
        parseFloat(TESTCURRENCY.toString().match(/^\d+(?:\.\d{0,2})?/))
      );
    } else {
      $('#valueshow').val('Invalid a value!');
    }
  });
});

Edit: New check a value to valid/invalid
