Got JS Fiddle to work
http://jsfiddle.net/pskjxofo/
Attached I have the following function, the purpose of which is to perform basic calculation. I also added a feature for adding more boxes for calculation. What I am currently stuck on is how to tell Javascript to make dynamic divs, and how to tell it to perform the same calculations for each line every time I click on Calculate. Assistance on this would be greatly appreciated. Thank you all in advance.
<div id="redo">
2 X
<input type="text" id="initial">
= <input type="text" id="solved">
<input type="submit" value="Calculate" onclick="calculait()">
<input type="submit" value="Add Another Box" onclick="addmore()">
</div>
<div id="main"></div>
<script type="text/javascript">
function calculait(){
var first = document.getElementById('initial');
var second = document.getElementById('solved');
second.value = first.value * 2;
}
function addmore(){
var bar = document.getElementById('main');
bar.innerHTML = bar.innerHTML + "<div id='redo'>2 X
<input type='text' id='initial'> = <input type='text' id='solved'>
<input type='submit' value='Calculate' onclick='calculait()'
<input type='submit' value='Add Another Box' onclick='addmore()";
}
</script>
Here is one of the many ways to do it. You could have this HTML structure:
<div id="main">
<div class="operation">
2 X <input type="text" class="initial"/>=
<input type="text" class="solved"/>
</div>
</div>
<input type="submit" value="Calculate" onclick="calculait()"/>
<input type="submit" value="Add Another Box" onclick="addmore()"/>
And this JS:
// Main container for all operations
var main = document.getElementById('main');
// Piece of HTML you'll be duplicating
var op = document.getElementsByClassName('operation')[0].outerHTML;
function calculait() {
// Get every operation div
var operations = document.getElementsByClassName('operation');
// For each of them, calculate
for(var i=0, l=operations.length; i<l; i++){
operations[i].getElementsByClassName('solved')[0].value =
parseFloat(operations[i].getElementsByClassName('initial')[0].value) * 2;
}
}
function addmore() {
main.insertAdjacentHTML('beforeend',op);
}
JS Fiddle Demo
If I understood correctly, I think this code will help.
First of all, change your ids for classes (IDs must be always unique in the page).
<input type="text" class="initial">
<input type="text" class="solved">
And in the JS, you use a for to iterate for this elements.
function calculait() {
var initial = document.getElementsByClassName('initial');
var solved = document.getElementsByClassName('solved');
for (var i = 0; i < initial.length; i++) {
solved[i].value = initial[i].value * 2;
}
}
function addmore() {
var bar = document.getElementById('main');
var html = "<div>2 X ";
html += "<input type='text' class='initial'> = ";
html += "<input type='text' class='solved'>";
html += "</div>";
bar.innerHTML = bar.innerHTML + html;
}

Give it a try and let me know if it helps!
When you write JavaScript use a debugger, your code didn't parse. You can find one in your browser by hitting F12.
Don't repeat yourself. A clean solution is to put html to duplicate into a template or similar and call a function to copy it.
Use input type=number for numbers.
<html>
<meta charset="utf-8">
<template id="calculate_template">
<form id="" class="calculate_form">
<input value="2" type="number" name="initial_1"> X
<input type="number" name="initial_2"> =
<input type="number" name="solved" disabled="disabled" >
</form>
</template>
<div id="main">
<button onclick="addmore();">Add Another Box</button>
<button onclick="calculate();">Calculate</button>
</div>
<script type="text/javascript">
function calculate(){
/*Calculates all*/
var forms = document.getElementsByClassName('calculate_form'),
i,
length = forms.length;
for(i = 0; i < length; i++){
console.log(forms[i]);
forms[i]['solved'].value = forms[i]['initial_1'].value * forms[i]['initial_2'].value;
}
}
function addmore(){
var main = document.getElementById('main');
main.insertAdjacentHTML("beforeend", document.getElementById('calculate_template').innerHTML);
}
addmore();
</script>
</html>
Demonstration
Here's a way of doing it:
var counter = 0;
function calculait(calculationId) {
var first = document.getElementById('initial' + calculationId);
var second = document.getElementById('solved' + calculationId);
second.value = first.value * 2;
}
function addmore() {
counter++;
var bar = document.getElementById('main');
var newDiv = document.createElement("div");
newDiv.id = "redo" + counter;
newDiv.innerHTML = "2 X <input type='text' id='initial" + counter + "'/> = <input type='text' id='solved" + counter + "'/><input type='submit' value='Calculate' onclick='calculait(" + counter + ")'/><input type='submit' value='Add Another Box' onclick='addmore(" + counter + ")'/>";
bar.appendChild(newDiv);
}
<div id="main"><div id="redo0">2 X <input type="text" id="initial0" /> = <input type="text" id="solved0" /><input type="button" value="Calculate" onclick="calculait(0)" /><input type="button" value="Add Another Box" onclick="addmore(0)" /></div>
</div>
HTML
<p id="operations"></p>
<p>
<input type="submit" value="Calculate" onclick="calc()" />
<input type="submit" value="Add operation" onclick="addOp()" />
</p>
Javascript
var id = 0, multiplier = 2;
var operations = document.getElementById('operations');
function addOp() {
++id;
var p = document.createElement("p");
var right = document.createElement("input");
right.id = 'right_' + id;
right.type = 'text';
var result = document.createElement('input');
result.id = 'result_' + id;
right.type = 'text';
p.innerHTML = multiplier + ' x ';
p.appendChild(right);
p.innerHTML += ' = ';
p.appendChild(result);
operations.appendChild(p);
}
function calc() {
for(var i = 1; i <= id; i++) {
var right = document.getElementById('right_' + i);
var result = document.getElementById('result_' + i);
result.value = multiplier * right.value;
}
}
addOp();

I have a situation where user may insert the Total Quantity and also the Total Pass and Total Fail. I have created a function where when the number of Total Pass inserted, the loop (of entering the pass score) will run according to the iterations inputted.
However, I do not want to have the loop to display the line Enter The Score : in the JavaScript function. Therefore, I want the function to call a div from the HTML itself.
For example, I want the <div id="outputPass"><p>Enter the score : <input type="text" /></p></div> to be called in the loop function which I have created in the document.getElementById('btnPass').onclick = function().
I have inserted some comments in the code section.
document.getElementById('btnPass').onclick = function() {
var totalIterations = parseInt(document.getElementById('inputPass').value);
var output = document.getElementById('outputPass');
var quantity = document.getElementById('quantity').value;
output.innerHTML = '';
if (quantity < totalIterations) {
alert("Invalid Input, Pass Value(" + totalIterations + ") Bigger than Quantity(" + quantity + ")");
} else {
for (var i = 1; i <= totalIterations; i++) {
var item = document.createElement('div');
//Call <div> from HTML
item.innerHTML = "";
output.appendChild(item);
}
}
};
document.getElementById('btnFail').onclick = function() {
var totalIterations = parseInt(document.getElementById('inputFail').value);
var output = document.getElementById('outputFail');
var quantity = document.getElementById('quantity').value;
output.innerHTML = '';
if (quantity < totalIterations) {
alert("Invalid Input, Fail Value(" + totalIterations + ") Bigger than Quantity(" + quantity + ")");
} else {
for (var i = 1; i <= totalIterations; i++) {
var item = document.createElement('div');
//Call <div> from HTML
item.innerHTML = "";
output.appendChild(item);
}
}
};
function togglePass() {
var x = document.getElementById("passDiv");
if (x.style.display === "block") {
x.style.display = "none";
} else {
x.style.display = "block";
}
}
function toggleFail() {
var y = document.getElementById("failDiv");
if (y.style.display === "block") {
y.style.display = "none";
} else {
y.style.display = "block";
}
}
.display {
display: none;
}
<form method="post" name="form">
<p>Enter the quantity : <input type="text" id="quantity" name="quantity" /></p><br />
<input type="button" value="Pass" onclick="togglePass()">
<input type="button" value="Fail" onclick="toggleFail()">
<div id="passDiv" class="display">
<p>Enter Total Pass : <input type="text" id="inputPass" name="inputPass" /> <input type="button" value="Key In Score" id="btnPass" onclick="return validate();"></p><br />
<!--This Div-->
<div id="outputPass">
<p>Enter the score : <input type="text" /></p>
</div>
<br />
<input type="button" value="DONE">
</div>
<br />
<div id="failDiv" class="display">
<p>Enter Total Fail : <input type="text" id="inputFail" /> <input type="button" value="Key In Score" id="btnFail"></p><br />

<div id="outputFail">
<p>Enter the score : <input type="text" /></p>

You can make the following changes to achieve what you are looking for:
Initially we're giving an id of pscore/fscore (for pass and fail respectively) to the <p></p> tags and hiding them.
<p id="fscore" style="display:none">Enter the score : <input type="text" /></p>
We're accessing them in the javascript code in the form of variables pscore and fscore respectively. (Make sure they are declared globally outside)
var pscore = document.getElementById('pscore');
var fscore = document.getElementById('fscore');
Then in the iterations we can just make a clone of the pscore/fscore , give a class of pscore/fscore to the <p></p> tags and remove the id of pscore/score (to avoid duplicate IDs), changing the display to block and append it to the output container by using the following:
var cln = pscore.cloneNode(true);
cln.style.display="block";
cln.className ="pscore";
cln.removeAttribute("id");
item.appendChild(cln);
var cln = fscore.cloneNode(true);
cln.style.display="block";
cln.removeAttribute("id");
cln.className ="fscore";
item.appendChild(cln);
var pscore = document.getElementById('pscore');
var fscore = document.getElementById('fscore');
document.getElementById('btnPass').onclick = function() {
var totalIterations = parseInt(document.getElementById('inputPass').value);
var output = document.getElementById('outputPass');
var quantity = document.getElementById('quantity').value;
output.innerHTML = '';
if (quantity < totalIterations) {
alert("Invalid Input, Pass Value(" + totalIterations + ") Bigger than Quantity(" + quantity + ")");
} else {
for (var i = 1; i <= totalIterations; i++) {
var item = document.createElement('div');
//Call <div> from HTML
var cln = pscore.cloneNode(true);
cln.style.display = "block";
cln.className = "pscore";
cln.removeAttribute("id");
item.appendChild(cln);
output.appendChild(item);
}
}
};
document.getElementById('btnFail').onclick = function() {
var totalIterations = parseInt(document.getElementById('inputFail').value);
var output = document.getElementById('outputFail');
var quantity = document.getElementById('quantity').value;
output.innerHTML = '';
if (quantity < totalIterations) {
alert("Invalid Input, Fail Value(" + totalIterations + ") Bigger than Quantity(" + quantity + ")");
} else {
for (var i = 1; i <= totalIterations; i++) {
var item = document.createElement('div');
//Call <div> from HTML
var cln = fscore.cloneNode(true);
cln.style.display = "block";
cln.className = "fscore";
cln.removeAttribute("id");
item.appendChild(cln);
output.appendChild(item);
}
}
};

I want to make a JavaScript function, which, after pressing a button, takes the list of checkbox elements with their content, checks all the checkboxes, creates a div element with these checkboxes and writes the result to the HTML form.
Here is my code:
function confirmDrivers() {
$('#selectedList').find('.chk').prop("checked", true);
var list = document.getElementById('selectedList').getElementsByTagName("li");
var myForm = document.getElementById('formInput');
var text = "<strong>Selected Drivers: </strong> <br><br>";
var myDiv = document.createElement("div");
myDiv.setAttribute("id","selectedInputDrivers");
myDiv.style.overflowY = "auto";
myDiv.style.maxHeight = "100px";
myDiv.style.maxWidth = "250px";
for (i = list.length - 1; i >= 0; i--) {
myDiv.innerHTML = list[i].innerHTML+'<br>'+myDiv.innerHTML;
}
$("formInput").find('.chk').prop("checked", true);
myForm.innerHTML = myDiv.outerHTML + myForm.innerHTML;
myForm.innerHTML = text + myForm.innerHTML;
}
Here is the HTML Div element with the list of checkbox elements. They also appear dynamically. Initially, Div is empty.
<div id = "selectedList" class = "col" style=" max-height:200px; max-width:500px;display: inline-block; background:#A8D9F1; overflow-y:auto">
<strong style="margin-right:10px">Selected List of Drivers</strong>
<input type="button" style="margin-right:10px" value="Remove All" name="removeAllDr" onclick="removeAllDrivers()" />
<input type="button" id="confirmD" value="Confirm" name="confirm" onclick="confirmDrivers()" />
<br><br>
</div>
And this is the HTML form, where I want my result to appear:
<form id="formInput">
</form>
The problem here is that it checks all the checkboxes in my list, but in the resulting HTML form they appear unchecked again. What is wrong with it? Thank you
Besides replacing prop() to attr() as Rik Lewis correctly recommended you can alternately put the line
$("formInput").find('.chk').prop("checked", true);
at the bottom of the function and add the # character in front the selector id like this:
function confirmDrivers() {
$('#selectedList').find('.chk').prop("checked", true);
var list = document.getElementById('selectedList').getElementsByTagName("li");
var myForm = document.getElementById('formInput');
var text = "<strong>Selected Drivers: </strong> <br><br>";
var myDiv = document.createElement("div");
myDiv.setAttribute("id","selectedInputDrivers");
myDiv.style.overflowY = "auto";
myDiv.style.maxHeight = "100px";
myDiv.style.maxWidth = "250px";
for (i = list.length - 1; i >= 0; i--) {
myDiv.innerHTML = list[i].innerHTML+'<br>'+myDiv.innerHTML;
}
myForm.innerHTML = myDiv.outerHTML + myForm.innerHTML;
myForm.innerHTML = text + myForm.innerHTML;
$("#formInput").find('.chk').prop("checked", true);
}
function confirmDrivers() {
$('#selectedList').find('.chk').prop("checked", true);
var list = document.getElementById('selectedList').getElementsByTagName("li");
var myForm = document.getElementById('formInput');
var text = "<strong>Selected Drivers: </strong> <br><br>";
var myDiv = document.createElement("div");
myDiv.setAttribute("id", "selectedInputDrivers");
myDiv.style.overflowY = "auto";
myDiv.style.maxHeight = "100px";
myDiv.style.maxWidth = "250px";
for (i = list.length - 1; i >= 0; i--) {
myDiv.innerHTML = list[i].innerHTML + '<br>' + myDiv.innerHTML;
}
myForm.innerHTML = myDiv.outerHTML + myForm.innerHTML;
myForm.innerHTML = text + myForm.innerHTML;
$("#formInput").find('.chk').prop("checked", true);
}

I want to total the values of all input, but in the beginning there's only one input element and you add the clone(s) with a button. Actually I have two issues:
1. How to place the clone node always under the node before it.
2. How to total the values of all nodes.
Here's the code:
function nambahData() {
var a = document.getElementById("harga");
var b = a.cloneNode(false);
document.getElementById("form").appendChild(b);
}
function ditotal() {
var x = document.getElementById("harga").value;
var y = document.getElementById("harga").childNode.value;
document.getElementById("total").value = parseInt(x) + parseInt(y);
}
</script>
<div id="form">
<input id="harga" type=number>
<br>
</div>
<button onclick="nambahData()">add data</button>
<br>
<button onclick="ditotal()">total all</button>
<input id="total" type=number>
Hope this helps you ..
window.nambahData = function() {
var a = document.getElementsByName("harga");
var b = a[0].cloneNode(false);
document.getElementById("form").appendChild(b);
}
window.ditotal = function() {
var totalItems = 0;
for(i=document.getElementsByName("harga").length-1;i>=0;i--)
{
var item = document.getElementsByName("harga")[i];
totalItems += parseFloat(item.value);
}
document.getElementById("total").value = totalItems;
}
.inputStyle{
display:block;
}
<div id="form">
<input name="harga" type="number" class="inputStyle">
</div>
<button onclick="nambahData()">add data</button>
<br>
<button onclick="ditotal()">total all</button>
<input id="total" type=number>
I am using a javascript function to populate html element generated automatically after submitting a form from a different div.
Here is the html:
<html >
<body>
<div class="wrapper">
<div id="one">
<form name="form">
<fieldset>
<legend>BILLING</legend>
<div> <label for="ex1">Procedure/Drug</label>
<input type="text" name="procdrug" id="procdrug"/><br><br>
<label>Amount</label>
<input type="text" name="amount" id="amount"/><br><br>
<input type="button" onclick="addInput()" name="add" value="Add input field" style="margin-left:150px" />
</div>
</fieldset>
</form>
</div>
<div id="two">
<fieldset>
<legend>TN QUEUE</legend>
<label><B>Procedure/Drug</b></label><label><b>Amount</b></label><br>
<div id="text">
</div>
<label><b>Total</b></label>
<input type="text" name="total" id="total"/>
</fieldset>
</div>
</body>
</html>
Here is the javascript function
<script language="javascript">
fields = 0;
function addInput() {
var amount=document.getElementById('amount').value;
var pd=document.getElementById('procdrug').value;
if (fields != 10)
{
document.getElementById('text').innerHTML += "<input id='pdgen' type='text'/>";
document.getElementById('text').innerHTML += "<input id='amtgen' type='text'/><br />";
document.getElementById('pdgen').value=pd;
document.getElementById('amtgen').value=amount;
fields += 1;
}
else
{
document.getElementById('text').innerHTML += "<br />Only A Maximum of 10 is allowed.";
document.form.add.disabled=true;
}
}
</script>
The generated elements values are posted from the form and increment on every submit. My problem is the only on submit first element is updated with the new value:
Sample results
Procedure/Drug Amount
Amoxyl 200
blank element blank element
blank element blank element
blank element blank element
Total
The problem is you are adding your elements with the .innerHtml += method which is avoiding the values entered before. You need to use appendChild method to add new elements. Here is your new code :
fields = 0;
function addInput() {
var amount=document.getElementById('amount').value;
var pd=document.getElementById('procdrug').value;
var br = document.createElement('br');
if (fields != 10)
{
var input1 = document.createElement('input');
input1.setAttribute('id','pdgen' + fields);
input1.value = pd;
var input2 = document.createElement('input');
input2.setAttribute('id','amtgen' + fields);
input2.value = amount;
document.getElementById('text').appendChild(input1);
document.getElementById('text').appendChild(input2);
document.getElementById('text').appendChild(br);
fields++;
}
else
{
document.getElementById('text').innerHTML += "<br />Only A Maximum of 10 is allowed.";
document.form.add.disabled=true;
}
}

I need some help: I have the following form:
<form id="myForm" method="post" action="?action=agc">
<input type="hidden" name="start_date" value="<?= $_POST['start_date'] ?>" />

<script>
var optionNumber = 1;
function addOption() {
var theForm = document.getElementById("myForm");
var newOption = document.createElement("input");
var newOption2 = document.createElement("input");
var newOption3 = document.createElement("input");
var newLabel = document.createElement("label");
var newContent = document.createTextNode(" ");
var newContent2 = document.createTextNode(" ");

theForm.appendChild(newOption2);
theForm.appendChild(newContent2);
newOption3.name = "poll[option]["+optionNumber+"][control_sample]";
newOption3.type = "checkbox";
newOption3.className = "optionBox";
newOption3.value = "True"
theForm.appendChild(newOption3);
theForm.appendChild(document.createElement("br"));
optionNumber++;
}
</script>
</p>
</div>
<div class="modal-footer" id="appendform">
<button type="submit" class="btn btn-primary">Continue</button>
</form>
Now because some of the inputs are generated on request, I have no idea how to check the sum of the(.toAdd). And I basically need to make sure that it's equal to 100 before submitting. What would be a solution to my problem? Thanks.
Try
<form id="myForm" method="post" action="iap_crm_campaign.php?action=abngamecampaign" onsubmit="return validate()">
Then
function validate(){
var sum = 0;
for(var i = 0; i < optionNumber; i++){
sum += parseFloat(document.getElementsByName('poll[option][' + i + '][percent]')[0].value);
}
if( sum == NaN || sum != 100){
alert('Sum of percentage must be 100');
return false;
}
}
Demo: Fiddle
var total = 0;
var toAdds = document.getElementsByClassName("toAdd");
for (var i = 0; i < toAdds.length; i++) {
total += parseInt(toAdds[i].value, 0);
}
if (total == 100) {
// OK
} else {
// not OK
}
Also, your code for adding new options needs to set the class:
newOption.className = "toAdd";
you can use jquery
$(".toAdd").length
or in simple js
var myInputs= document.getElementsByTagName('input');
var noOfInputs =myInputs.length;
well this will give you the count of i/p elements through loop, for summing the values...
var sum;
$(".toAdd").each(function() {
sum=sum+$(this).val();
});
