I have one textbox.It should be allow only decimal numbers and after dot only allow two digit(example 34545.43). how we can do it using jquery i have searched in google and stackoverflow but not satisfied answer because some script is not working in chrome and firefox. I tried but it is not working properly.So need help how to do it.http://jsfiddle.net/S9G8C/1685/
Js:
$('.allow_decimal').keyup(function (evt) {
var self = $(this);
self.val(self.val().replace(/[^0-9\.]/g, ''));
if ((evt.which != 46 || self.val().indexOf('.') != -1) && (evt.which < 48 || evt.which > 57)) {
evt.preventDefault();
}
});
This jQuery function will round the value on blur event of textbox
$.fn.getNum = function() {
var val = $.trim($(this).val());
if(val.indexOf(',') > -1) {
val = val.replace(',', '.');
}
var num = parseFloat(val);
var num = num.toFixed(2);
if(isNaN(num)) {
num = '';
}
return num;
}
$(function() { //This function will work on onblur event
$('#txt').blur(function() {
$(this).val($(this).getNum());
});
});
Number: <input type="text" id="txt" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
You can directly remove the 3rd digit when the user enters that.
var txt = document.getElementById('txtId');
txt.addEventListener('keyup', myFunc);
function myFunc(e) {
var val = this.value;
var re = /^([0-9]+[\.]?[0-9]?[0-9]?|[0-9]+)$/g;
var re1 = /^([0-9]+[\.]?[0-9]?[0-9]?|[0-9]+)/g;
if (re.test(val)) {
//do something here
} else {
val = re1.exec(val);
if (val) {
this.value = val[0];
} else {
this.value = "";
}
}
}
<input id="txtId" type="text"></input>

I have a situation having a textbox having 15 as a max length property. That field works as a amount field. it is working correctly in normal cases.
lets say if i enter 11234567890.99 this amount in textbox it displays it as 112,34,567,890.99 which is expected.
But, if i copy & paste 112,34,567,890.99 amount in textbox last two digits gets truncated because the length gets out of bound.
Is there any ways to change this without modifying the exact behavior? allowing to paste whole 112,34,567,890.99 amount.

split = number_string.split(','),
sisa = split[0].length % 3,
rupiah = split[0].substr(0, sisa),
ribuan = split[0].substr(sisa).match(/\d{1,3}/gi);
if (ribuan) {
separator = sisa ? '.' : '';
rupiah += separator + ribuan.join('.');

rupiah = split[1] != undefined ? rupiah + ',' + split[1] : rupiah;
return prefix == undefined ? rupiah : (rupiah ? 'Rp. ' + rupiah : '');
}

This might suit you. On keydown prevent the default action if it is not a number key. On keyup, parse the value and update it. Use the data- attributes to store and get the original value.
var elem = document.getElementById("num");
elem.addEventListener("keydown",function(event){
var key = event.which;
if((key<48 || key>57) && key != 8) event.preventDefault();
});
elem.addEventListener("keyup",function(event){
var value = this.value.replace(/,/g,"");
this.dataset.currentValue=parseInt(value);
var caret = value.length-1;
while((caret-3)>-1)
{
caret -= 3;
value = value.split('');
value.splice(caret+1,0,",");
value = value.join('');
}
this.value = value;
});
function showValue()
{
console.log(document.getElementById("num").dataset.currentValue);
}
<input type="text" id="num" maxlength="30">
<button onclick="showValue()">Get Value</button>
Ok I have posted answer below. I have added limit of 20 numbers. You can change it as per your need.
You can use Number.toLocaleString() for this purpose.
Below is working example:
// When ready.
$(function() {
var extra = 0;
var $input = $("#amount");
$input.on("keyup", function(event) {
// When user select text in the document, also abort.
var selection = window.getSelection().toString();
if (selection !== '') {
return;
}
// When the arrow keys are pressed, abort.
if ($.inArray(event.keyCode, [38, 40, 37, 39]) !== -1) {
if (event.keyCode == 38) {
extra = 1000;
} else if (event.keyCode == 40) {
extra = -1000;
} else {
return;
}
}
var $this = $(this);
// Get the value.
var input = $this.val();
var input = input.replace(/[\D\s\._\-]+/g, "");
input = input ? parseInt(input, 10) : 0;
input += extra;
extra = 0;
$this.val(function() {
return (input === 0) ? "" : input.toLocaleString("en-US");
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="amount" name="amount" type="text" maxlength="20" />
change your the input type equal to "text" then its work
<input type="text" id="tanpa-rupiah" step="any">

When a user enters numeric values I just want to display even number I want to set prevent default on odd values.
HTML:
Enter any number: <input type="text">
<p id="even"></p>
JavaScript:
function (e) {
e.preventDefault();
}
You can add an event listener to the input element and validate that the number is even.
DEMO
JavaScript
var num = document.getElementById('num');
var out = document.getElementById('out');
var isNumber = function(n) { return n == parseFloat(n); }
var isEven = function(n) { return isNumber(n) && (n % 2 == 0); }
var isOdd = function(n) { return isNumber(n) && (Math.abs(n) % 2 == 1); }
var myFunction = function(e) {
var val = num.value;
if (isEven(val)) {
out.innerHTML = val;
} else {
e.preventDefault();
}
};
num.addEventListener('blur', myFunction, false);
HTML
Enter any number: <input type="text" id="num" />
<hr />
Value: <span id="out"></span>
Update
If you want live validation, change blur to keyup.
num.addEventListener('keyup', myFunction, false);
If you are asking how to detect an odd value, you could use something like
function whatever(e){
if(value % 2 != 0){
e.preventDefault()
}else{
//Do something
}
}
Probably something like this:
$("input").mouseup(function() {
var num = $(this).val();
if (num % 2) {
console.log(num);
}
});
EDIT: and here it is in plain JS:
var el = document.getElementsByTagName("input")[0];
el.onkeyup = function () {
var num = el.value;
if (num % 2 == false) {
console.log(num);
}
};
Is it possible to translate this jquery code into javascript?
$("#field").keypress(function (evt) {
if (evt.which == 46) {
$(this).val($(this).val() + ',');
evt.preventDefault();
}
//The input of more than 2 numbers after the decimal point is prevented
var foo = $(this).val();
if( !foo.match(/^(\d)*,?(\d){0,1}$/) ){
evt.preventDefault();
}
});

Thanx in advance!
Finally i have found a solution. Hope it helps anybody
<script type="text/javascript">
function decimals(that) {
var s = that.value;
var i = s.indexOf(".");
if (i < 0 || s.substr(i+1).length < 2) return;
alert("Only 1 digit to the right of the decimal are allowed!");
that.value = s.substring(0,i+2);
}
</script>
<input type="text" size="5" maxlength="5" onkeyup="decimals(this)">

I have a problem masking a phone input with jQuery and Masked Input Plugin.
There are 2 possible formats:
(XX)XXXX-XXXX
(XX)XXXXX-XXXX
Is there any way to mask it accepting both cases?
EDIT:
I tried:
$("#phone").mask("(99) 9999-9999");
$("#telf1").mask("(99) 9999*-9999");
$("#telf1").mask("(99) 9999?-9999");
But it doesn't works as I would like.
The closest one was (xx)xxxx-xxxxx.
I would like to get (xx)xxxx-xxxx when I type the 10th number, and (xx)xxxxx-xxxx when I type the 11th. Is it posible?
Try this - http://jsfiddle.net/dKRGE/3/
$("#phone").mask("(99) 9999?9-9999");
$("#phone").on("blur", function() {
var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );
if( last.length == 3 ) {
var move = $(this).val().substr( $(this).val().indexOf("-") - 1, 1 );
var lastfour = move + last;
var first = $(this).val().substr( 0, 9 );
$(this).val( first + '-' + lastfour );
}
});
Here is a jQuery phone number mask. No plugin required.
Format can be adjusted to your needs.
Updated JSFiddle.
HTML
<form id="example-form" name="my-form">
<input id="phone-number" name="phone-number" type="text" placeholder="(XXX) XXX-XXXX">
</form>
JavaScript
$('#phone-number', '#example-form')
.keydown(function (e) {
var key = e.which || e.charCode || e.keyCode || 0;
$phone = $(this);
// Don't let them remove the starting '('
if ($phone.val().length === 1 && (key === 8 || key === 46)) {
$phone.val('(');
return false;
}
// Reset if they highlight and type over first char.
else if ($phone.val().charAt(0) !== '(') {
$phone.val('('+$phone.val());
}
// Auto-format- do not expose the mask as the user begins to type
if (key !== 8 && key !== 9) {
if ($phone.val().length === 4) {
$phone.val($phone.val() + ')');
}
if ($phone.val().length === 5) {
$phone.val($phone.val() + ' ');
}
if ($phone.val().length === 9) {
$phone.val($phone.val() + '-');
}
}
// Allow numeric (and tab, backspace, delete) keys only
return (key == 8 ||
key == 9 ||
key == 46 ||
(key >= 48 && key <= 57) ||
(key >= 96 && key <= 105));
})
.bind('focus click', function () {
$phone = $(this);
if ($phone.val().length === 0) {
$phone.val('(');
}
else {
var val = $phone.val();
$phone.val('').val(val); // Ensure cursor remains at the end
}
})
.blur(function () {
$phone = $(this);
if ($phone.val() === '(') {
$phone.val('');
}
});
Actually the correct answer is on http://jsfiddle.net/HDakN/
Zoltan answer will allow user entry "(99) 9999" and then leave the field incomplete
$("#phone").mask("(99) 9999-9999?9");
$("#phone").on("blur", function() {
var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );
if( last.length == 5 ) {
var move = $(this).val().substr( $(this).val().indexOf("-") + 1, 1 );
var lastfour = last.substr(1,4);
var first = $(this).val().substr( 0, 9 );
$(this).val( first + move + '-' + lastfour );
}
});
You need a jQuery plugin for the mask works as well.
-- HTML --
<input type="text" id="phone" placeholder="(99) 9999-9999">
<input type="text" id="telf1" placeholder="(99) 9999*-9999">
<input type="text" id="telf2" placeholder="(99) 9999?-9999">
-- JAVASCRIPT --
<script src="https://raw.githubusercontent.com/igorescobar/jQuery-Mask-Plugin/master/src/jquery.mask.js"></script>
<script>
$(document).ready(function($){
$("#phone").mask("(99) 9999-9999");
$("#telf1").mask("(99) 9999*-9999");
$("#telf2").mask("(99) 9999?-9999");
});
</script>
You can use the phone alias with Inputmask v3
$('#phone').inputmask({ alias: "phone", "clearIncomplete": true });
$(function() {
$('input[type="tel"]').inputmask({ alias: "phone", "clearIncomplete": true });
});
<label for="phone">Phone</label>
<input name="phone" type="tel">

Using jQuery Mask Plugin there is two possible ways to implement it:
1- Following Anatel's recomendations:
https://gist.github.com/3724610/5003f97804ea1e62a3182e21c3b0d3ae3b657dd9
2- Or without following Anatel's recomendations:
https://gist.github.com/igorescobar/5327820
All examples above was coded using jQuery Mask Plugin and it can be downloaded at:
http://igorescobar.github.io/jQuery-Mask-Plugin/
var $phone = $("#input_id");
var maskOptions = {onKeyPress: function(phone) {
var masks = ['(00) 0000-0000', '(00) 00000-0000'];
mask = phone.match(/^\([0-9]{2}\) 9/g)
? masks[1]
: masks[0];
$phone.mask(mask, this);
}};
$phone.mask('(00) 0000-0000', maskOptions);
With jquery.mask.js
http://jsfiddle.net/brynner/f9kd0aes/
HTML
<input type="text" class="phone" maxlength="15" value="85999998888">
<input type="text" class="phone" maxlength="15" value="8533334444">
JS
// Function
function phoneMask(e){
var s=e.val();
var s=s.replace(/[_\W]+/g,'');
var n=s.length;
if(n<11){var m='(00) 0000-00000';}else{var m='(00) 00000-00000';}
$(e).mask(m);
}
// Type
$('body').on('keyup','.phone',function(){
phoneMask($(this));
});
// On load
$('.phone').keyup();
Only jQuery
http://jsfiddle.net/brynner/6vbrqe6z/
HTML
<p class="phone">85999998888</p>
<p class="phone">8599998888</p>
jQuery
$('.phone').text(function(i, text) {
var n = (text.length)-6;
if(n==4){var p=n;}else{var p=5;}
var regex = new RegExp('(\\d{2})(\\d{'+p+'})(\\d{4})');
var text = text.replace(regex, "($1) $2-$3");
return text;
});
The best way to do this is using the change event like this:
$("#phone")
.mask("(99) 9999?9-9999")
.on("change", function() {
var last = $(this).val().substr( $(this).val().indexOf("-") + 1 );
if( last.length == 3 ) {
var move = $(this).val().substr( $(this).val().indexOf("-") - 1, 1 );
var lastfour = move + last;
var first = $(this).val().substr( 0, 9 ); // Change 9 to 8 if you prefer mask without space: (99)9999?9-9999
$(this).val( first + '-' + lastfour );
}
})
.change(); // Trigger the event change to adjust the mask when the value comes setted. Useful on edit forms.
The best way to do it on blur is:
function formatPhone(obj) {
if (obj.value != "")
{
var numbers = obj.value.replace(/\D/g, ''),
char = {0:'(',3:') ',6:' - '};
obj.value = '';
upto = numbers.length;
if(numbers.length < 10)
{
upto = numbers.length;
}
else
{
upto = 10;
}
for (var i = 0; i < upto; i++) {
obj.value += (char[i]||'') + numbers[i];
}
}
}
As alternative
function FormatPhone(tt,e){
//console.log(e.which);
var t = $(tt);
var v1 = t.val();
var k = e.which;
if(k!=8 && v1.length===18){
e.preventDefault();
}
var q = String.fromCharCode((96 <= k && k <= 105)? k-48 : k);
if (((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) && e.keyCode!=46 && e.keyCode!=37 && e.keyCode!=8 && e.keyCode!=39) {
e.preventDefault();
}
else{
setTimeout(function(){
var v = t.val();
var l = v.length;
//console.log(l);
if(k!=8){
if(l<4){
t.val('+7 ');
}
else if(l===4){
if(isNaN(q)){
t.val('+7 (');
}
else{
t.val('+7 ('+q);
}
}
else if(l===7){
t.val(v+')');
}
else if(l===9){
t.val(v1+' '+q);
}
else if(l===13||l===16){
t.val(v1+'-'+q);
}
else if(l>18){
v=v.substr(0,18);
t.val(v);
}
}

I was developed simple and easy masks on input field to US phone format jquery-input-mask-phone-number
Simple Add jquery-input-mask-phone-number plugin in to your HTML file and call usPhoneFormat method.
$(document).ready(function () {
$('#yourphone').usPhoneFormat({
format: '(xxx) xxx-xxxx',
});
});
Working JSFiddle Link https://jsfiddle.net/1kbat1nb/
NPM Reference URL https://www.npmjs.com/package/jquery-input-mask-phone-number
GitHub Reference URL https://github.com/rajaramtt/jquery-input-mask-phone-number
If you don't want to show your mask as placeholder you should use jQuery Mask Plugin.
The cleanest way:
var options = {
onKeyPress: function(phone, e, field, options) {
var masks = ['(00) 0000-00000', '(00) 00000-0000'];
var mask = (phone.length>14) ? masks[1] : masks[0];
$('.phone-input').mask(mask, options);
}
};
$('.phone-input').mask('(00) 0000-00000', options);
Yes use this
$("#phone").inputmask({"mask": "(99) 9999 - 9999"});
Link here
$('.phone').focus(function(e) {
// add mask
$('.phone')
.mask("(99) 99999999?9")
.focusin(function(event)
{
$(this).unmask();
$(this).mask("(99) 99999999?9");
})
.focusout(function(event)
{
var phone, element;
element = $(this);
phone = element.val().replace(/\D/g, '');
element.unmask();
if (phone.length > 10) {
element.mask("(99) 99999-999?9");
} else {
element.mask("(99) 9999-9999?9");
