loop javascript function for each row after add new row

I have a row in a table that can be duplicated by javascript. In the first row I have a javascript code that makes a calculation.
After duplicating a new row the calc javascript is not working for the new row..
What i do wrong?
table row:
<table class="Parameter" id="new">
<form action="ProjectParameterNewRecord.php" method="post">
<tr>
<td>
<input type="text" id="Parameters" name="TypeOfOut" />
</td>
<td>
<?php include "ExchangeRates.php"?>
</td>
</td>
<td>
<input id="Cost" type="number" value="" class="ee105" name="Cost" onchange="changeCost()">
</td>
<td>
<input id="Amount" type="number" value="" class="ee105" name="Amount" onchange="changeAmount()">
</td>
<td><span id="minisum" name="minisum" onchange="changeminisum()"></span>
</td>
<td id="system">
<input type="hidden" id="ParameterID" name="ParameterID"></input>
</td>
<td id="system">
<input type="hidden" id="ProjectID" name="ProjectID" value="3"></input>
</td>
<td>
<input type="submit" value="Submit">
</td>
</form>
</tr>
</table>
code to create a new row:
<script>
var counter = 1;
jQuery('img.add-author').click(function(event){
event.preventDefault();
counter++;
var newRow = jQuery(' <tr class="Parameters" id="AA"><td><input type="text" id="Parameters" name="TypeOfOut"/></td><td><select id="Unit" type="text" value=" " class="ee105" name="Unit" onchange="changeUnit(this.value)"><option value="2">KM</option><option value="4">euro</option><option value="3">$</option><option value="25">WorkHour</option><option value="3">dollar</option><option value="25">WorkHour</option> </select</td></td><td><input id="Cost" type="number" value="" class="ee105" name="Cost" onchange="changeCost()"></td><td><input id="Amount" type="number" value="" class="ee105" name="Amount" onchange="changeAmount()"></td><td><span id="minisum" name="minisum" onchange="changeminisum()"></span></td><td id="system"><input type="hidden" id="ParameterID" name="ParameterID' + counter +'"></input></td><td id="system"><input type="hidden" id="ProjectID" name="ProjectID" value="3"></input></td><td><input type="submit" value="Submit"></td></tr>');
jQuery('table.Parameter#new').append(newRow);
});
</script>
javascript code to calculate:
function CalcUnitValue() {
var U = document.getElementById("Unit").value;
var SUM = -1 * ((((($('#Amount').val())) * (((($('#Cost').val())) * (($('#Unit').val())))))));
document.getElementById("minisum").innerHTML = SUM;
document.getElementById("minisum").readOnly = true;
}
function changeCost() {
var C = document.getElementById("Cost").value;
var SUM = -1 * ((((($('#Amount').val())) * (((($('#Cost').val())) * (($('#Unit').val())))))));
document.getElementById("minisum").innerHTML = SUM;
document.getElementById("minisum").readOnly = true;
}
function changeAmount() {
var C = document.getElementById("Amount").value;
var SUM = -1 * ((((($('#Amount').val())) * (((($('#Cost').val())) * (($('#Unit').val())))))));
document.getElementById("minisum").innerHTML = SUM;
document.getElementById("minisum").readOnly = true;
}
function changeUnit() {
var C = document.getElementById("Amount").value;
var SUM = -1 * ((((($('#Amount').val())) * (((($('#Cost').val())) * (($('#Unit').val())))))));
document.getElementById("minisum").innerHTML = SUM;
document.getElementById("minisum").readOnly = true;
}
function minisum() {
var SUM = -1 * ((((($('#Amount').val())) * (((($('#Cost').val())) * (($('#Unit').val())))))));
return alert(document.getElementById('minisuminput').innerHTML);
thank you :)

Your HTML is invalid. You have an extra closing </td> in the middle. You also need to put the form outside the table.
You can't have duplicate IDs in a HTML page and expect to reference anything except the first one. Use classes instead.
Don't use inline event handlers with jQuery. Use delegated jQuery handlers if you have dynamically added elements.
Use an element hidden in the page to hold your template. If you store it in the HTML, and not code, you would have noticed your </select> was missing and replaced by an extra </td>.
You mix JavaScript selectors with jQuery. Just stick to jQuery selectors. They are shorter.
None of the extra parenthesis are required for a * b * c * d equations.
inputs and img elements are meant to be self-closing, not have end tags.
All your calculations are exactly the same, so reuse the code.
Get into the habit on using consistent case (upper/lower/mixed) for variables and classes.
Use delegated event handlers like this:
$(document).on('change', '.cost,.amount,.unit,.parameters', function() {
var $tr = $(this).closest('tr');
var sum = -1 * $('.Amount', $tr).val() * $('.cost', $tr).val() * $('.Unit', $tr).val();
$(".minisum", $tr).html(sum);
}
Re templating: you can store your template row in a dummy script block, with unknown type (I use text/template) and it will be ignored by the browser.
e.g.
<script id="template" type="text/template">
<tr class="Parameters" id="AA">
<td>
<input type="text" class="Parameters" name="TypeOfOut" />
</td>
<td>
<select class="Unit ee105" type="text" value=" " name="Unit">
<option value="2">KM</option>
<option value="4">euro</option>
<option value="3">$</option>
<option value="25">WorkHour</option>
<option value="3">dollar</option>
<option value="25">WorkHour</option>
</select>
</td>
<td>
<input class="cost" type="number" value="" name="Cost">
</td>
<td>
<input class="amount ee105" type="number" value="" name="Amount">
</td>
<td><span class="minisum" name="minisum"></span></td>
<td class="system">
<input type="hidden" class="ParameterID" name="ParameterID{counter}" />
</td>
<td class="system">
<input type="hidden" class="ProjectID" name="ProjectID" value="3" />
</td>
<td>
<input type="submit" value="Submit">
</td>
</tr>
</script>
You will note a {counter} placeholder where you wanted to insert a new value. Use it as the HTML source to create new rows.
e.g.
$('table.Parameter#new').append($('#template').html().replace('{counter}', counter));
JSFiddle to play with ( most of this functional): https://jsfiddle.net/TrueBlueAussie/33e9ptgu/

It looks like your problem is coming from having duplicate ids. When there are duplicate ids, the behavior of document.getElementById() is undefined. Each browser will try to do something reasonable, but there's no way to know which element will be returned (though it's usually the first element).
One option is to change the duplicated ids to class, and then when creating a new row, give the row it's own unique id using your counter:
var newRow = jQuery(' <tr class="Parameters" id="' + counter + '"><td>.....</td></tr> ');
This will allow you to access whichever row you want for calculation, as well as it's children using jquery:
Instead of $('#Cost') or document.getElementById("minisum"), use $('#' + [number of rowid]).find('.Cost'); or $('#' + [number of rowid]).find('.minisum');
A couple of other tips:
To get the value of an <input> into your functions, simply pass it as a parameter like so: onchange="changeCost(value)". Now you can delete 3 of your 4 identical functions as well as remove the first line of the remaining one.
You don't need closing </input> tags (see here)
There are two </td> tags on your second column
Make sure you have correct tag nesting on your </tr> and </form> tags

Javascript adding fields dynamically in table without updating the form

JSFiddle with the code: http://jsfiddle.net/wxLa80od/
I have a html page which is looks like:
<form action="cvformphp.php" method="post">
<table id="cvtable">
<tr><td><h2>Personal Info</h2></td></tr>
<tr><td>Name* </td> <td><input type="text" name="name"></td></td>
<tr><td>Email* </td><td><input type="Email" name="email"></td></tr>
<tr><td><h2>Experiences</h2></td></tr>
<tr><td>Job role </td><td><input type="text" id="role1" name="role1"></td> <td>Company name</td><td><input type="text" id="comp1" name="comp1"></td </tr>
<input type="text" hidden="hidden" value="1" id="countexp" name="countexp"/>
<tbody id="exp" name="exp"></tbody>
<tr><td></td><td><input type="button" id="2" value="+ Add More" onclick="addExp()"/></td></td></tr>
</table>
</form>
with javascript code
<script>
var countBox =2;
function addExp()
{
document.getElementById("countexp").value= countBox;
document.getElementById("exp").innerHTML +="<br/><tr><td>Job role</td><td>
<input type='text' id='role"+ countBox +"' name='role"+ countBox+"'/></td>
<td>Company name</td><td><input type='text' name='comp"+ countBox +"'
id='comp"+countBox +"''/> </td></tr>";
countBox += 1;
}
</script>
The code is running well but the problem is when I click "Add more" button the dynamic added fields is getting empty!
I want to fill all data in the form so I can pass them to php file.
Could someone perhaps tell me please how I can not clear the fields?
Thanks in advance.

When using innerHtml, you ALWAYS replace the content with the newly defined content, even if you use +=. That's why your dynamic content is empty after each click on the button.
I will provide 2 solutions for this problem. One of them requires the use of jQuery, the other doesn't (but is more complicated):
Solution 1 (WITH jQuery)
function addExp()
{
document.getElementById("countexp").value= countBox;
$("#exp").append("<tr><td>Job role</td> \
<td><input type='text' id='role"+ countBox +"' \
name='role"+ countBox+"'/></td><td>Company name</td>\
<td><input type='text' name='comp"+ countBox +"' \
id='comp"+countBox +"''/> </td></tr>");
countBox += 1;
}
jsFiddle: http://jsfiddle.net/wxLa80od/4/
Solution 2 (WITHOUT jQuery)
function addExp()
{
document.getElementById("countexp").value= countBox;
var newChild = document.createElement("tr");
document.getElementById("countexp").value= countBox;
// Create an empty <tr> element and add it to the 1st position of the table:
var row = document.getElementById("exp").insertRow(-1);
// Insert new cells (<td> elements) at the 1st and 2nd position of the "new" <tr> element:
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
// Add some text to the new cells:
cell1.innerHTML = "Job role";
cell2.innerHTML = "<input type='text' id='role"+ countBox +"' name='role"+ countBox+"'/>";
cell3.innerHTML = "Company name";
cell4.innerHTML = "<input type='text' name='comp"+ countBox +"'id='comp"+countBox +"''/>";
countBox += 1;
}
jsFiddle: http://jsfiddle.net/wxLa80od/2/
Also a quick note: do NOT use <br/> in between two rows <tr>, it can create a mess really quickly. Please use css for this (example: margin-bottom: 15px;)

innerHTML does not get the value inputted from keyboard. You may use appendChiled. In that case you should create element using createElement statement. It is easier to use jquery. Try following code
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.2.min.js"></script>
<script>
var countBox =2;
function addExp()
{
document.getElementById("countexp").value= countBox;
$("#exp").append("<br><tr><td>Job role</td><td><input type='text' id='role"+ countBox +"' name='role"+ countBox+"'/></td><td>Company name</td><td><input type='text' name='comp"+ countBox +"' id='comp"+countBox +"''/> </td></tr>");
countBox += 1;
}
</script>
</head>
<body>
<form action="cvformphp.php" method="post">
<table id="cvtable">
<tr><td><h2>Personal Info</h2></td></tr>
<tr><td>Name* </td> <td><input type="text" name="name"></td></td>
<tr><td>Email* </td><td><input type="Email" name="email"></td></tr>
<tr><td><h2>Experiences</h2></td></tr>
<tr><td>Job role </td><td><input type="text" id="role1" name="role1"></td> <td>Company name</td><td><input type="text" id="comp1" name="comp1"></td ></tr>
<input type="text" hidden="hidden" value="1" id="countexp" name="countexp"/>
<tbody id="exp" name="exp"></tbody>
<tr><td></td><td><input type="button" id="2" value="+ Add More" onclick="addExp()"/></td></td></tr>
</table>
</form>
</body>
</html>

According to answer of this question I agreed. But! we can do the needful for the required/expected result as below and also can make your own stuff for the expected/required result if you know JavaScript well.
function getInputValues(container){
if(!(container instanceof Node) || !(container instanceof HTMLElement)){
container = document.querySelector(container);
}
let values = {};
container.querySelectorAll("INPUT").forEach((el)=>{
values[el.name] = el.value;
});
return values;
}
function setInputValues(container, values){
if(!(container instanceof Node) || !(container instanceof HTMLElement)){
container = document.querySelector(container);
}
Object.keys(values).forEach((key)=>{
container.querySelector("INPUT[name='"+key+"']").value = values[key];
});
}
Before the document.getElementById("exp").innerHTML += you have to get the values and after the added/updated html you have to set the values for the same inputs and if you want to use input name as array then you can set the index values also and also can change the input attribute from name to id or any other unique attribute from the function of getInputValues to make everything woks perfectly.
I wrote this code for my own project and you also can make your own if required otherwise it'll help's you

How to clear Input data from within JQuery Div

I have a simple form users can fill out and also add a new form to add multiple entries.
Everything works fine except when I enter data in the first set of inputs and click create new memberships it will take the data from the form and put it in the text boxes.
How can I stop that?
http://jsfiddle.net/811yohpn/2/
I have tried a couple different ways.
$('#education').find('input:text').val('');
$('#education: input').val('');
However that will clear all entries.

Call find on the newDiv, instead of all inputs within #education.
Updated fiddle
newDiv.find('input:text').val('');
var ed = 1;
function new_education() {
ed++;
var newDiv = $('#education div:first').clone();
newDiv.attr('id', ed);
var delLink = '<a class="btn btn-danger" style="text-align:right;margin-right:65px" href="javascript:deled(' + ed + ')" > Delete Education ' + ed + ' </a>';
newDiv.find('tr:first th').text('Education ' + ed);
newDiv.append(delLink);
newDiv.find('input:text').val(''); // <----------- added this
$('#education').append(newDiv);
}
function deled(eleId) {
d = document;
var ele = d.getElementById(eleId);
var parentEle = d.getElementById('education');
parentEle.removeChild(ele);
//ed--;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<legend>Education</legend>
<div id="education">
<div id="1">
<table border=3>
<tr>
<th colspan="4" style="background-color:#b0c4de;">Education 1</th>
</tr>
<tr>
<td>
<label>School Name</label>
<input type="text" name="schoolname[]" maxlength="30" size="30"/>
</td>
<td>
<label>Degree Type</label>
<input type="text" name="degreetye[]" maxlength="30" size="30"/>
</td>
<td>
<label>Degree Field</label>
<input type="text" name="degreefield[]" maxlength="30" size="30"/>
</td>
</tr>
</table>
</div>
</div>
<br/><a class="js-addNew btn btn-info" href="javascript:new_education()"> Add New Education </a>

You need to clear the inputs under the cloned element
newDiv.find('input').val('')
Demo: Fiddle
Your selectors are selecting all input elements within the #education container, that is not what you want. The newDiv variable refers to the newly created element so you can use that to find the input elements within in and then clear it

jQuery - checkboxes selecting all on a row or with similar names & ID's

Using jQuery 1.9.1 & getting XML returned from a query that needs to be displayed in a web page as shown in the picture below. I had asked a similar question several days ago but was all over the place in what I was asking. Hope to ask better questions this time.
For the items in the picture, the XML input would be:
<Classrooms>
<Room Number="3">
<Machine>310</Machine>
<Machine>320</Machine>
<Machine>340</Machine>
<Machine>350</Machine>
</Room>
<Room Number="8">
<Machine>810</Machine>
<Machine>820</Machine>
<Machine>840</Machine>
</Room>
<Room Number="10">
<Machine>1010</Machine>
<Machine>1020</Machine>
</Room>
</Classrooms>
The code below is a function that is called upon a successful AJAX GET and builds the checkboxes in a table on the web page.
var $roomList = $( items );
var roomListString = jQ_xmlDocToString( $roomList );
var roomListXML = $.parseXML(roomListString);
$(roomListXML).find("Row").each(function() {
var activeRooms = $( roomListXML ).find("Row").text();
var nbrRooms = $(activeRooms).find("Room").size();
$(activeRooms).find("Room").each(function() {
var roomNo = $(this).attr("Number");
var roomchk = "Room"+roomNo;
var $tr = $("<tr />");
$tr.append('<td><input type="checkbox" name="'+roomchk+'" id="'+roomchk+'" class="checkall" /><label for="'+roomchk+'">Room '+roomNo+'</td>');
$("#mytable").append( $tr );
$(this).children().each(function() {
var machID = $(this).text();
var idname = "Room"+roomNo+"Mach"+machID;
$tr.append('<td><input type="checkbox" name="'+idname+'" id="'+idname+'" /><label for="'+idname+'">'+machID+'</td>');
$("#mytable").append( $tr );
});
});
});
When the above code is run on the data, the HTML in the table is as shown below.
<tbody>
<tr>
<td>
<input name="Room3" id="Room3" class="checkall" type="checkbox" />
<label for="Room3">Room 3</label>
</td>
<td>
<input name="Room3Mach310" id="Room3Mach310" type="checkbox" />
<label for="Room3Mach310">310</label>
</td>
<td>
<input name="Room3Mach320" id="Room3Mach320" type="checkbox" />
<label for="Room3Mach320">320</label>
</td>
<td>
<input name="Room3Mach340" id="Room3Mach340" type="checkbox" />
<label for="Room3Mach340">340</label>
</td>
<td>
<input name="Room3Mach350" id="Room3Mach350" type="checkbox" />
<label for="Room3Mach350">350</label>
</td>
</tr>
<tr>
<td>
<input name="Room8" id="Room8" class="checkall" type="checkbox" />
<label for="Room8">Room 8</label>
</td>

<input name="Room8Mach810" id="Room8Mach810" type="checkbox" />
<label for="Room8Mach810">810</label>
</td>
<td>
<input name="Room8Mach820" id="Room8Mach820" type="checkbox" />
<label for="Room8Mach820">820</label>
</td>
<td>
<input name="Room8Mach840" id="Room8Mach840" type="checkbox" />
<label for="Room8Mach840">840</label>
</td>
</tr>
<tr>
<td>
<input name="Room10" id="Room10" class="checkall" type="checkbox" />
<label for="Room10">Room 10</label>
</td>
<td>
<input name="Room10Mach1010" id="Room10Mach1010" type="checkbox" />
<label for="Room10Mach1010">1010</label>
</td>
<td>
<input name="Room10Mach1020" id="Room10Mach1020" type="checkbox" />
<label for="Room10Mach1020">1020</label>
</td>
</tr>
</tbody>
Selection of any checkbox on the page will enable a SUBMIT button on the page, which when clicked will pass the value of the boxes checked into another function. The user can select any number of the individual boxes (the ones with the number beside them), regardless of the room those items are associated with. When the user selects a Room checkbox though, ALL the individual checkboxes for that room should also be checked. The individual values are the ones I want. When the SUBMIT button is clicked, the individual values are all that will be sent to that function.
I had looked at this topic about using a checkbox class to select all.
I'm using the code below to find what's checked. I can see when I select an individual box that it gets added to the array. I can also see when I select a Room that the checkall is found, but I can't seem to make the individual checkboxes get checked once I do. I had been attempting to use the Attribute Starts With jQuery selector, but haven't been able to get it to check the boxes.
$("#mytable").click(function(e) {
var ele = $(this).find(":checkbox");
var zall = $(this).find(":checkbox.checkall:checked");
if (zall) {
var zname = $(zall).attr("name");
var selectallmachines = "input[name^='" + zname +"']:checked:enabled";
$( $(selectallmachines), "#mytable");
}
var arr = [];
$(":checkbox:checked").each(function(i) {
arr[i] = $(this).val();
});
});
I'm sure that it is something that I'm overlooking, but what am I missing? Would appreciate any suggestions or guidance on what I'm doing wrong, or if there's perhaps a better way to do what I'm doing.
Thanks!

You can do something like this
$('.checkall').change(function(){
$('input[id^='+this.id+']').prop('checked',this.checked);
});
when .checkall is clicked/changes - set checked property on all inputs with an id that starts with the current clicked elements id
FIDDLE
Though you probably should delegate since you are using ajax to get the elements - this is assuming #mytable exists on DOM Ready - or replace with an ancestor element that does
$('#mytable').on('click','.checkall',function(){
$('input[id^='+this.id+']').prop('checked',this.checked);
});
another alternative is to give the checkall id as a class to the relative checkboxes
$tr.append('<td><input type="checkbox" name="'+idname+'" id="'+idname+'" class="'+roomchk+'"/><label for="'+idname+'">'+machID+'</td>');
then you can do
$('#mytable').on('click','.checkall',function(){
$('input.'+this.id).prop('checked',this.checked);
});
FIDDLE

dynamically generate textboxes using JavaScript

I want generate textboxes dynamically according to user input. If user enter the integer value in the textbox, if he/she enter 5 i want generate 5 textboxes. This code is working in Firefox but not working in IE and Netscape; please help me how to do this or point out any other mistake in this code to me. Also, the technology we are using is Struts 2.
Please help me.
JavaScript code:
function generate()
{
var tot = document.getElementById("totmob").value;
var tbl = document.getElementById("sim");
for(var i =1;i<=tot;i++)
{
tbl.innerHTML = 'Mobile No'+i+' <input type="text" size = "20" maxlength= "20" name= hoardingregister.mobileno> <br> \n';
}
HTML code:
<td>
<s:textfield id="totmob" label="Total Mobile Number" />
<td>
<td>
<input type="button" value="ADD" onclick="generate()"/>
</td>
</tr>
</table>
<div id="sim">
</div>

for(var i =1;i<=tot;i++)
{
tbl.innerHTML = 'Mobile No'+i+' <input type="text" size = "20" maxlength= "20" name= hoardingregister.mobileno> <br> \n';
}
should be
for(var i =1;i<=tot;i++)
{
tbl.innerHTML += 'Mobile No'+i+' <input type="text" size = "20" maxlength= "20" name= hoardingregister.mobileno> <br> \n';
}
because you need to append to the inner HTML, rather than replace it.
You've also used a <td> instead of a </td>

Can you try something else than InnerHtml - you can try this:
use GetElementByID to get the element you want to add text boxes to
remove any existing child items if required
Add textboxes as child items to the selected node

From your javascript code, it looks you should use following code:
tbl.innerHTML +=
instead of
tbl.innerHTML =
inside the for loop.

The code below works perfect for me in IE as well as Firefox. When you say It's nt working, what do you mean ?
function generate()
{
var tot = document.getElementById("totmob").value;
var tbl = document.getElementById("sim");
for(var i =1;i<=tot;i++)
{
tbl.innerHTML = tbl.innerHTML +'Mobile No'+i+' <input type="text" size = "20" maxlength= "20" name= hoardingregister.mobileno> <br> \n';
}
}
</script>
<body>
<table>
<tr>
<td>
<span>Total Mobile Number </span>
<input type="text" id="totmob" />
<td>
<td>
<input type="button" value="ADD" onclick="generate()"/>
</td>
</tr>
</table>
<div id="sim">
</div>
</body>
</html>

add a unique identifier to the name of the input or a unique id to it.
like:
for(var i =1;i<=tot;i++)
{
tbl.innerHTML += 'Mobile No'+i+' <input type="text" size = "20" maxlength= "20" name= hoardingregister.mobileno'+i+'> <br> \n';
}
or you put a id into it like:
id="input"+i

But if you are changing the value in the text box without refreshing the page more text boxes are adding after the previously added text box. But it is wrong whenever we change the value in the text box only tat number of new text boxes should be added instead of keeping the previous text boxes too. Can you please change the coding according to the conditions I said.
