I have a question
I want to display the input form in the currency format, but I have a problem that the input form must be clicked first.
This is my code input HTML
<label class="col-md-12 col-sm-12 col-xs-12 padding-0">Harga Jual</label>
<div class="col-md-12 col-sm-12 col-xs-12 padding-0">
<input type="text" class="form-control currency" id="hargabarang" readonly="readonly">
</div>
My code currency
<script>
$(document).ready(function() {
$('.currency').maskMoney({prefix:'Rp. ', thousands:'.', decimal:',', precision:0});
})
My calculate
<script type="text/javascript">
$(document).ready(function(){
$("#jumlah").keyup(function(){
var jumlah = parseInt($("#jumlah").val());
var minimal_jual = $("#minimal_jual").val();
var minimal_grosir1 = $("#minimal_grosir1").val();
var minimal_grosir2 = $("#minimal_grosir2").val();
var minimal_grosir3 = $("#minimal_grosir3").val();

var satuan_grosir3 = $("#satuan_grosir3").val();
if (jumlah < minimal_grosir1) {
var satuan = satuan_jual;
} else if(jumlah >= minimal_grosir1 && jumlah < minimal_grosir2) {
var satuan = satuan_grosir1;

Javascript for card shuffle failing

Over my head with javascript. I'm trying to get the cards to shuffle when clicking next.
Currently, it moves forward with one random shuffle and stops. Back and forward buttons then no longer work at that point.
Please help—many thanks.
When I'm lost and unsure what sample of the code to pinpoint, the captions go up to 499. The sample is also here: https://rrrhhhhhhhhh.github.io/sentences/
Very new to javascript. So any help is greatly appreciated. Very open to better ways to achieve this???
How I have it set up:
HTML:
var r = -1;
var mx = 499; // maximum
var a = new Array();
function AddNumsToDict(){
var m,n,i,j;
i = 0;
j = 0;
while (i <= 499)
{
m = (500 * Math.random()) + 1;
n = Math.floor(m);
for (j=0;j<=499;j++)
{
if (a[j] == (n-1))
{
j = -1;
break;
}
}
if (j != -1)
{
//a.push(n-1);
a[i] = (n-1);
i++;
j=0;
}
}
return;

for (var i=0; i < aCookie.length; i++)
{
// a name/value pair (a crumb) is separated by an equal sign
var aCrumb = aCookie[i].split("=");
if (sName == aCrumb[0])
return unescape(aCrumb[1]);

// a cookie with the requested name does not exist
return null;

this my javascript code to count value and display it in input value.
<div class="form-group">
<label class="control-label col-md-3 col-sm-3 col-xs-12" for="ppn"><?php print _('mi_invoice_ppn'); ?></label>
<div class="col-md-6 col-sm-6 col-xs-12">
<div class="input-group">
<span class="input-group-addon" style="border-radius:0px;">Rp</span>
<input type="text" name="ppn" id="ppn" class="form-control" onkeydown="return numbersonly(this, event);" onkeyup="javascript:tandaPemisahTitik(this);" placeholder="0" />
</div>
</div>
</div>
this is the input code. i want change input text value has been count in javascript function. i want to manually changed again. so javascript function to count automatic. and can edit again if miscalculation.
If you want to recalculate when any input value's changed, you can add change listener on the input elements.
will be look like:
let inputElems = document.querySelectorAll("input");
for (let i = 0, len = inputElems.length; i < len; i++) {
inputElems[i].addEventListener("change", countsisa);
}

Custom Form Validation Messages

My variable refused to display in my Div

The country is changing along side the shipping. I could alert my shipping but will refuse to display in my div. What could be wrong? All calculations working well and displays well except for the #usashipping please help. My country changes and give the correct value for the calculation. The shipping fee just will not display.

Your code should work perfectly, but there are few things that you could improve in your code:
Instead of declaring shipping variable 3 times in each condition, you need to declare it only once, then update it in each condition, and make sure it's stored as a string so it can be displayed correctly in your HTML.
Instead of updating the HTML content of your span in every condition, just update it with the shipping amount in the end.
This is how should be your code:
$('#country').change(function() {
var input = $(this).val();
var shipping;
if (input == 40) {
shipping = '10.0';
} else if (input == 236) {
shipping = '20.0';
} else {
shipping = '30.0';
}
$('#usashipping').html(shipping);
});
Demo:
$('#country').change(function() {
var input = $(this).val();
var shipping;
if (input == 40) {
shipping = '10.0';
} else if (input == 236) {
shipping = '20.0';
} else {
shipping = '30.0';
}
$('#usashipping').html(shipping);
});

<option value="40">40</option>
<option value="236">236</option>
<option value="100">100</option>
</select>
<div>
Shipping Fee = $<span data-shipping-fee="" id="usashipping"></span>
</div>
I can see error showing in your code. I found "$('.add').click" inside "$('#country').change". Also "$('#country').change" function you declared local variable "var shipping;" that's why no change on global "shipping;" value but you using it inside "$('#country').change" function. I modified little bit now try with following code and comment reply if not work for you:
var price= "";
var userprice="";
var flpay='';
var total='';
var shipping='';
var fees=30.0;
$('#country').change(function() {
var input = $(this).val();
if (input == 40) {
shipping = 10.0;
$('#usashipping').html('10.0');
} else if (input == 236) {
shipping = 10.0;

}
if(fees=='') {
$('#fees').html(30);
}
if(flpay=='')
{
$('#flpay').html(2*19.99);
}
if(total=='')
{
var tot=19.99*2.0 +30.0 + shipping;
var total= tot.toFixed(2);
$('#total').html(total);
}
})
$('.add').click(function () {
var $input = $(this).next();
var currentValue = parseInt($input.val());
var newinput = currentValue + 1;
$('#gems').val(newinput);
(newinput);
if (newinput == 1) {
var np1 = (19.99 * 2.0);
flpay = np1.toFixed(2);
$('#flpay').html(flpay);
var tot = (fees + shipping + flpay);
var total = tot.toFixed(2);
$('#total').html(total);
var newp = 19.99;
var price = newp.toFixed(2);
$('#price').html(price);
useprice = 19.99;
}
else if (newinput > 1) {
//useprice=useprice;
var newprice = 19.99 + (9.99 * (newinput - 1));
var np1 = (2 * newprice);
var flpay = np1.toFixed(2);
$('#flpay').html(flpay);
var tot = (fees + shipping + (2 * newprice));
var total = tot.toFixed(2);
$('#usashipping').html(shipping);
$('#total').html(total);
var newp = newprice.toFixed(2);
$('#price').html(newp);
}
// newprice= price * 2;
// $('#price').html(newprice);
})
I only changed the div id from #usashipping to something else and it works just fine. Maybe #usashippingis now a constant in jquery library.

How can I copy this function but with preset values?

Currently when a button is clicked, it subtracts an inputted value. I want to have a preset value subtracted once a preset button is clicked. It would also be perferable that I could reuse a function later on a different button with different values like so:
var preset = function(val1, val2, val3, val4) {
//function to subtract from current values
}
$('presetButton').click(function(){
preset(1,2,3,4)
}
Here is the current function as I have it. The first button function works, but I wanted to copy it into a preset button with preset values. The function would not include $(this) because the button would not be in the same wrapper div and are not siblings.
$(document).ready(function(){
$('button').click(function(){
var $button = $(this);
var subtract = parseInt($button.siblings('input').val(), 10);
var $currentP = $button.siblings('.number').children('p');
var current = parseInt($currentP.text(), 10);
var newVal = current - subtract;
var $history = $button.siblings('.wrap').children('.history');
if (isNaN(subtract)) {
alert("Please enter in a number");
} else {
$currentP.effect('bounce', function() {
$currentP.text(newVal);
$(this).show();
});
$history.append("<p>"+subtract+"</p>");
}
});
$('#presets').click(function(){
//set up the subtracting and current variables
var subCal = 120;
var subPro = 24;
var subCarbs = 3;
var subFat = 1;
//retrieve current number then convert to a number
var toNum = function(id) {
return parseInt($(id + ' .number').children('p').text(), 10);
}
var curCal = toNum('#calories');
var curPro = toNum('#protein');
var curCarbs = toNum('#carbs');
var curFat = toNum('#fats');
//create new values
var newCal = curCal - subCal;
var newPro = curPro - subPro;
var newCarbs = curCarbs - subCarbs;
var newFat = curFat - subFat;
//apply new values
var applyNew = function(id, newVal) {
$(id + ' .number p').text(newVal)
}
applyNew('#calories', newCal);
applyNew('#protein', newPro);
applyNew('#carbs', newCarbs);
applyNew('#fats', newFats);
//Add to presets to history
})
});
