php - How can I format currency by using JQuery -


this question has answer here:

i trying format currency using 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 work volume such "$10,000" or that, how can include thousands, hundreds, , millions in 1 code?

here nice function in vanilla js handles things:

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

however, jquery, turn plug-in, or use like:

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