How can I format currency by using JQuery

currency, jquery, php

Solution

Here is a nice function in vanilla JS that handles things:

var format = function(num){
    var str = num.toString().replace("$", ""), parts = false, output = [], i = 1, formatted = null;
    if(str.indexOf(".") > 0) {
        parts = str.split(".");
        str = parts[0];
    }
    str = str.split("").reverse();
    for(var j = 0, len = str.length; j < len; j++) {
        if(str[j] != ",") {
            output.push(str[j]);
            if(i%3 == 0 && j < (len - 1)) {
                output.push(",");
            }
            i++;
        }
    }
    formatted = output.reverse().join("");
    return("$" + formatted + ((parts) ? "." + parts[1].substr(0, 2) : ""));
};

However, for jQuery, you could always turn it into a plug-in, or just use it like:

$(function(){
    $("#currency").keyup(function(e){
        $(this).val(format($(this).val()));
    });
});

EDIT I updated the fiddle JSFiddle

Problem

I am trying to format currency by using this code below: ``` $('#currency').keyup(function(e){ var val = $(this).val(); val = val.replace(/[^0-9]/g,''); if(val.length >= 2) val = '$' + val.substring(0,2) + ',' + val.substring(2); if(val.length >= 6) val = val.substring(0,7) + val.substring(7); if(val.length > 7) val = val.substring(0,7); $(this).val(val); }); ``` But that would work only for volume such as "$10,000" or something like that, How can I include thousands, hundreds, and millions in one code?
