How to format and validate a credit card number with spaces between each 4 digit while typing:
eg: 4464 6846 4354 3564
I have tried:
$('.creditno').keyup(function() {
cc = $(this).val().split("-").join("");
cc = cc.match(new RegExp('.{1,4}$|.{1,4}', 'g')).join("-");
$(this).val(cc);
});
Please help
Try this:
function cc_format(value) {
var v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '')
var matches = v.match(/\d{4,16}/g);
var match = matches && matches[0] || ''
var parts = []
for (i=0, len=match.length; i<len; i+=4) {
parts.push(match.substring(i, i+4))
}
if (parts.length) {
return parts.join(' ')
} else {
return value
}
}

To restrict the user to enter number only:
Javascript Way
<input type="text" id="txt_cardNumber" name="txt_cardNumber" onkeypress="return checkDigit(event)">
function checkDigit(event) {
var code = (event.which) ? event.which : event.keyCode;
if ((code < 48 || code > 57) && (code > 31)) {
return false;
}
return true;
}
OR
function checkDigit() {
var allowedChars = "0123456789";
var entryVal = document.getElementById('txt_cardNumber').value();
var flag;
for(var i=0; i<entryVal.length; i++){
flag = false;
for(var j=0; j<allowedChars.length; j++){
if(entryVal.charAt(i) == allowedChars.charAt(j)) {
flag = true;
}
}
if(flag == false) {
entryVal = entryVal.replace(entryVal.charAt(i),""); i--;
}
}
return true;
}
HTML5 Way
<input type="text" id="txt_cardNumber" name="txt_cardNumber" pattern="[0-9.]+">
<input type="number" id="txt_cardNumber" name="txt_cardNumber">
jQuery Way
$("#txt_cardNumber").keypress(function (e) {
if ((e.which < 48 || e.which > 57) && (e.which !== 8) && (e.which !== 0)) {
return false;
}
return true;
});

Just wrote this to handle Visa, Discover, Master Card and Amex (with formatting and card type identification).
// SAMPLE FIELD: <input type="text" name="cstCCNumber" id="cstCCNumber" value=""onkeyup="cc_format('cstCCNumber','cstCCardType');">
function cc_format(ccid,ctid) {
// supports Amex, Master Card, Visa, and Discover
// parameter 1 ccid= id of credit card number field
// parameter 2 ctid= id of credit card type field
var ccNumString=document.getElementById(ccid).value;
ccNumString=ccNumString.replace(/[^0-9]/g, '');
// mc, starts with - 51 to 55
// v, starts with - 4
// dsc, starts with 6011, 622126-622925, 644-649, 65
// amex, starts with 34 or 37
var typeCheck = ccNumString.substring(0, 2);
var cType='';
var block1='';
var block2='';
var block3='';
var block4='';
var formatted='';
if (typeCheck.length==2) {
typeCheck=parseInt(typeCheck);
if (typeCheck >= 40 && typeCheck <= 49) {
cType='Visa';
}
else if (typeCheck >= 51 && typeCheck <= 55) {
cType='Master Card';
}
else if ((typeCheck >= 60 && typeCheck <= 62) || (typeCheck == 64) || (typeCheck == 65)) {
cType='Discover';
}
else if (typeCheck==34 || typeCheck==37) {
cType='American Express';
}
else {
cType='Invalid';
}
}
// all support card types have a 4 digit firt block
block1 = ccNumString.substring(0, 4);
if (block1.length==4) {
block1=block1 + ' ';
}
if (cType == 'Visa' || cType == 'Master Card' || cType == 'Discover') {
// for 4X4 cards
block2 = ccNumString.substring(4, 8);
if (block2.length==4) {
block2=block2 + ' ';
}
block3 = ccNumString.substring(8, 12);
if (block3.length==4) {
block3=block3 + ' ';
}
block4 = ccNumString.substring(12, 16);
}
else if (cType == 'American Express') {
// for Amex cards
block2 = ccNumString.substring(4, 10);
if (block2.length==6) {
block2=block2 + ' ';
}
block3 = ccNumString.substring(10, 15);
block4='';
}
else if (cType == 'Invalid') {

alert('Invalid Card Number');
}
formatted=block1 + block2 + block3 + block4;
document.getElementById(ccid).value=formatted;
document.getElementById(ctid).value=cType;
}
I couldn't find a reasonable solution that works with text editing, so here you go:
$("#cardNumber").on("keydown", function(e) {
var cursor = this.selectionStart;
if (this.selectionEnd != cursor) return;
if (e.which == 46) {
if (this.value[cursor] == " ") this.selectionStart++;
} else if (e.which == 8) {
if (cursor && this.value[cursor - 1] == " ") this.selectionEnd--;
}
}).on("input", function() {
var value = this.value;
var cursor = this.selectionStart;
var matches = value.substring(0, cursor).match(/[^0-9]/g);
if (matches) cursor -= matches.length;
value = value.replace(/[^0-9]/g, "").substring(0, 16);
var formatted = "";
for (var i=0, n=value.length; i<n; i++) {
if (i && i % 4 == 0) {
if (formatted.length <= cursor) cursor++;
formatted += " ";
}
formatted += value[i];
}
if (formatted == this.value) return;
this.value = formatted;
this.selectionEnd = cursor;
});
The keydown listener is needed to adjust the cursor position for backspace and delete to move past spaces. It should not be used to restrict character entry, as you don't want to use key codes for that.
The input listener rebuilds the text, strips non-numbers, adds spaces every 4 characters, and preserves the cursor position.
With ES6
export const formatCardNumber = value => {
const regex = /^(\d{0,4})(\d{0,4})(\d{0,4})(\d{0,4})$/g
const onlyNumbers = value.replace(/[^\d]/g, '')
return onlyNumbers.replace(regex, (regex, $1, $2, $3, $4) =>
[$1, $2, $3, $4].filter(group => !!group).join(' ')
)
}
function cc_format(value) {
var v = value.replace(/\s+/g, '').replace(/[^0-9]/gi, '')
var matches = v.match(/\d{4,16}/g);
var match = matches && matches[0] || ''
var parts = []
for (i=0, len=match.length; i<len; i+=4) {
parts.push(match.substring(i, i+4))
}
if (parts.length) {
return parts.join(' ')
} else {
return value
}
}
onload = function() {
document.getElementById('cc').oninput = function() {
this.value = cc_format(this.value)
}
}
function checkDigit(event) {
var code = (event.which) ? event.which : event.keyCode;
if ((code < 48 || code > 57) && (code > 31)) {
return false;
}
return true;

using angularjs directive. Format Card Numbers in xxxxxxxxxxxx3456 Fromat.
angular.module('myApp', [])
.directive('maskInput', function() {
return {
require: "ngModel",
restrict: "AE",
scope: {
ngModel: '=',
},
link: function(scope, elem, attrs) {

var edited = orig;

});
}
};
})
.controller('myCtrl', ['$scope', '$interval', function($scope, $interval) {
$scope.creditCardNumber = "1234567890123456";
}]);
using vanilla js
javascript:
function formatCreditCardOnKey(event) {
//on keyup, check for backspace to skip processing
var code = (event.which) ? event.which : event.keyCode;
if(code != 8)
formatCreditCard();
else{
//trim whitespace from end; trimEnd() doesn't work in IE
document.getElementById("cardNumber").value = document.getElementById("cardNumber").value.replace(/\s+$/, '');
}
}
function formatCreditCard() {
var cardField = document.getElementById("cardNumber");
//remove all non-numeric characters
var realNumber = cardField.value.replace(/\D/g,'');
var newNumber = "";
for(var x = 1; x <= realNumber.length; x++){
//make sure input is a digit
if (isNumeric(realNumber.charAt(x-1)))
newNumber += realNumber.charAt(x-1);
//add space every 4 numeric digits
if(x % 4 == 0 && x > 0 && x < 15)
newNumber += " ";
}
cardField.value = newNumber;
}
function isNumeric(char){
return('0123456789'.indexOf(char) !== -1);
}
HTML:
<input type="text" id="cardNumber" maxlength="19" onKeyUp="formatCreditCardOnKey(event)" onBlur="formatCreditCard()" onFocus="formatCreditCard()"/>
This works (for me) with autofill, allows the user to use backspace as expected (they don't have to delete whitespace), and doesn't allow (other) non-numeric characters.
<?php
function luhn_check($number) {
// Strip any non-digits (useful for credit card numbers with spaces and hyphens)
$number=preg_replace('/\D/', '', $number);
// Set the string length and parity
$number_length=strlen($number);
$parity=$number_length % 2;
// Loop through each digit and do the maths
$total=0;
for ($i=0; $i<$number_length; $i++) {
$digit=$number[$i];
// Multiply alternate digits by two
if ($i % 2 == $parity) {
$digit*=2;
// If the sum is two digits, add them together (in effect)
if ($digit > 9) {
$digit-=9;
}
}
// Total up the digits
$total+=$digit;
}
// If the total mod 10 equals 0, the number is valid
return ($total % 10 == 0) ? TRUE : FALSE;
}
?>
function testCreditCard () {
myCardNo = document.getElementById('CardNumber').value;
myCardType = document.getElementById('CardType').value;

This may simple way:
function numberFormat(x){
return x.replace(/(.{4})/g, "$1 ");
}
If you want to connect dash every 4 digits,
function numberFormat(x){
return x.replace(/(.{4})/g, "$1-");
}
export const removeNonNumber = (string = "") => string.replace(/[^\d]/g, "");
export const removeLeadingSpaces = (string = "") => string.replace(/^\s+/g, "");
const limitLength = (string = "", maxLength) => string.substr(0, maxLength);
const FALLBACK_CARD = { gaps: [4, 8, 12], lengths: [16], code: { size: 3 } };
const addGaps = (string = "", gaps) => {
const offsets = [0].concat(gaps).concat([string.length]);
return offsets
.map((end, index) => {
if (index === 0) return "";
const start = offsets[index - 1];
return string.substr(start, end - start);
})
.filter((part) => part !== "")
.join(" ");
};
//this method to call
_formatNumber = (number, card) => {
const numberSanitized = removeNonNumber(number);
const maxLength = card.lengths[card.lengths.length - 1];
const lengthSanitized = limitLength(numberSanitized, maxLength);
const formatted = addGaps(lengthSanitized, card.gaps);
//set your state here
return formatted;
};
//use above method like this in text input
cardEnter(strings = "") {
this._formatNumber(strings, FALLBACK_CARD);
}
Let's try this. This code will replace your edit number in real-time.
$(document).ready(function() {
document.getElementById('card_no').onkeyup = function (e) {
if (this.value == this.lastValue) return;
var caretPosition = this.selectionStart;
var sanitizedValue = this.value.replace(/[^0-9]/gi, '');
var parts = [];
for (var i = 0, len = sanitizedValue.length; i < len; i += 4) {
parts.push(sanitizedValue.substring(i, i + 4));
}
for (var i = caretPosition - 1; i >= 0; i--) {
var c = this.value[i];
if (c < '0' || c > '9') {
caretPosition--;
}
}
caretPosition += Math.floor(caretPosition / 4);
this.value = this.lastValue = parts.join(' ');
this.selectionStart = this.selectionEnd = caretPosition;
}
});

This should work :
const handleKeyup=(value)=>{
//Remove whitespace
let newValue = value.split(" ").join("")
var format =newValue.split("").map((data, index) => {
if ((index + 1) % 4 == 0) {
data = data + " "
}
return data
})
format= format.join("")
console.log("format", format)}
This should work:
var format = [9, 2, 3,5,5,5,5,5,5,5,4, 5, 5, 5, 54, 4, 4, 4, 4, 4, 4,4,4, 4].map((data, index) => {
if ((index + 1) % 4 == 0) {
data = data + " "
}
return data
})
format= format.join("")
console.log("format", format)
This will do the job
$('#card-number').on('keypress change blur', function () {
$(this).val(function (index, value) {
var trimValue = value.trim();
var cardDivider = trimValue.replace(/ /g,'').length % 4;
if (trimValue.length < 19 && trimValue !== "") {
if (cardDivider === 0) {
return trimValue + " ";
}
}
return trimValue;
});
});
just learned js for 15 days, and encountered the same problem doing a project.
here is my absolutely rubbish solution, it's js only, don't know why even mention that since I don't know what jquery, etc means.
however, it works.
ps: feel free to judge.
const number = document.getElementById("card-number");
//get the new array every time there is
//an input in the field
let listened_number = [];
//put spaces in the array
function number_format(){
listened_number.splice(4,0," ");
listened_number.splice(9,0," ");
listened_number.splice(14,0," ");
}
//"input" type, the function gets activated every time something is entered or deleted.
number.addEventListener("input", e => {
//update the array
listened_number = number.value.replace(/\s+/g,"").split('');
// input caret position before any changes
// 'variable' represents the action to be
//applied on the caret later on
let caret_pos = number.selectionStart;
let variable = 0;
if(e.data === null){
variable = -1;
}else{
variable = 1;
}
// add spaces into the array.
number_format();
// reduced together but trimmed
number.value = listened_number.reduce((pv, cv) => pv + cv).trim();
//!!!!
//because the number.value(content in the input
//field) is reassigned, the input caret will appear
//at the very end, which is not user-friendly at all
//!!!!
switch(caret_pos){
case 5:
setSelection(5 + variable);
break;
case 10:
setSelection(10 + variable);
break;
case 15:
setSelection(15 + variable);
break;
default:
setSelection(caret_pos);
}
})
// set the caret where it supposes to be.
function setSelection(caretPos){
number.setSelectionRange(caretPos,caretPos);
number.focus();
}
<input maxlength="19" id="card-number" type="text" placeholder="e.g. 1234 5678 9123 0000">
it's messy... i know.
I found everything above never worked so I wrote a new one for fomatting to
0000 0000 0000 0000
//JS credit card formatter for onChange handler
"97181237removed12891237192random3712".replace(/[\D]/g, '').match(/.{1,4}/g)?.join(' ').substring(0, 19) || '';
// '9718 1237 1289 1237'
https://gist.github.com/zakcroft/5c045ebbfa0d3e4aacc4d21fe0196ffa
Format credit card number will be 16 digits and having automatic spacing between them will get by trying the below code for me.
try it once
handlecard(text) {
let formattedText = text.split(' ').join('');
if (formattedText.length <= 16) {
if (formattedText.length > 0) {
formattedText = formattedText.match(new RegExp('.{1,4}', 'g')).join(' ');
}
} else {
alert("plz stop here")
}
this.setState({ creditCard: formattedText });
return formattedText;
}
Hello I'm stuck on how to add category for my to do list. When you click on Button of category need change class name. I don't understand how to correctly write if/else statement when button is clicked.
plan how it need to work
Write task name
Choose Category
Add new task
May be somebody can help me out ore give some advice how to solve this problem!
Sorry for my english and if my question is to badly explained!
var toDoList = function() {
var addNewTask = function() {
var input = document.getElementById("taks-input").value,
itemTexts = input,
colA = document.getElementById('task-col-a').children.length,
colB = document.getElementById('task-col-b').children.length,
taskBoks = document.createElement("div"),
work = document.getElementById("work"),
Category = "color-2",
taskCount = 1;
if (work.onclick === true) {
var Category = "color";
}
taskBoks.className = "min-box";
taskBoks.innerHTML = '<div class="col-3 chack" id="task_' + (taskCount++) + '"><i class="fa fa-star"></i></div><div class="col-8 task-text" id="taskContent"><p>' + itemTexts + '</p><span id="time-now"></span></div><div class="col-1 ' + (Category) + '"></div>'
if (colB < colA) {
var todolist = document.getElementById("task-col-b");
} else {
var todolist = document.getElementById("task-col-a");
}
//todolist.appendChild(taskBoks);
todolist.insertBefore(taskBoks, todolist.childNodes[0]);
},
addButton = function() {
var btn2 = document.getElementById("add-task-box");
btn2.onclick = addNewTask;
};
addButton()
}
toDoList();

you need to bind click event to your buttons and store that value in Category, so in you js add this
var toDoList = function() {
// set to default
var Category = "color-3";
// attach event to buttons
var catButtons = document.getElementsByClassName("catBtn");
// assign value based on event
var myCatEventFunc = function() {
var attribute = this.getAttribute("id");
if (attribute === 'work') {
Category = 'color';
} else if (attribute === 'home') {
Category = 'color-2';
}
};
for (var i = 0; i < catButtons.length; i++) {
catButtons[i].addEventListener('click', myCatEventFunc, false);
}
Demo: Fiddle
and remove this code from addNewTask function
if (work.onclick === true) {
var Category = "color";
}
It is a bit hard to understand what you are doing, what you are going for (a module of some kind?). You were not that far away from a working state.
