javascript - number input numeric only -


this question has answer here:

i have project want numbers input i'm using input of type number allows decimal seperators etc. how prevent use of , . , e.

i have looked around , couldn't find 1 gave desired result, sinds either didn't block decimal inputs, or allow user still paste in field.

i have javascript , jquery can use, not want use external librairy.

if able me appriciated.

function limitkeys($id) {             $field = document.getelementbyid($id);     $value = $($field).val(); //if value contains multiple e , or . value no longer valid , gives me blank     console.log($value);     $regex = /[^\d]/;      $val = $value.replace($regex, "");// cant replace in blank     console.log($val);     //$($field).val($val); }  $('.number-only').keypress(function (event) { //sinds it's on keypress won't catch paste of data.     console.log(this.value);     var regex = new regexp("^[0-9]+$");     var key = string.fromcharcode(!event.charcode ? event.which : event.charcode);     if (!regex.test(key)) {         event.preventdefault();         return false;     } }); 

try code

$(".number-only").on('input', function (e) {  //if letter not digit display error , don't type  if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {     //display error message     $(".error").html("only numbers allowed").show().fadeout("slow");            return false; } }); 

don't forget create error class.
