I'm stuck with javascript I working on. I want to add more fields dynamically, my problem is I want to be able to add a row with input boxes. Within the added row, first column contain checkbox, second column contain an increment number, third column contain input txtbox, fourth column checkbox1, fifth column contain input txtbox1 and sixth column contain input txtbox3. Now my question is, how would I add dynamicaly second row under fourth column checkbox1, fifth column txtbox1 and sixth column txtbox3 while maintaing alignment with checkbox,txtbox?
And within the added row, if possible it have to have two button, add row and delete row.
Here is snippet which runs but doesn't do want I expecting:

As much as I love plain/vanilla javascript, I would have to recommend jQuery for your next project. Here's a jsfiddle of the code using only plain/vanilla javascript.
Here's the JavaScript function you'll need
function hasClass(el, cssClass) {
return el.className && new RegExp("(^|\\s)" + cssClass + "(\\s|$)").test(el.className);
}
var rowNumber = 1;
function addRow(tableID) {
var counter = document.getElementById(tableID).rows.length-1;
var row = document.getElementById(tableID);
var newRow0 = row.rows[1].cloneNode(true);
var newRow1 = row.rows[counter].cloneNode(true);
// Increment
rowNumber ++;
newRow0.getElementsByTagName('td')[1].innerHTML = rowNumber;
// Update the child Names
var items = newRow0.getElementsByTagName("input");
for (var i = 0; i < items.length; i++) {
items[i].value = null;
items[i].name = counter + '_' + items[i].name;
}
var refRow = row.getElementsByTagName('tbody')[0];
refRow.insertBefore(newRow0, refRow.nextSibling);
refRow.insertBefore(newRow1, refRow.nextSibling);
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var i = table.rows.length - 1;
while (2 < i && !hasClass(table.rows[i], 'row-parent')) {
table.deleteRow(i)
i--;
}
if (2 < i) {
table.deleteRow(i)
rowNumber --;
}
}
function addChildRow(e, tableID) {
var table = document.getElementById(tableID);
var newRow = table.rows[0].cloneNode(true);
// Increment
if (e > 0)
if (!isNaN(table.rows[e-1].getElementsByTagName('td')[4].innerHTML))
var counter = parseInt(table.rows[e-1].getElementsByTagName('td')[4].innerHTML)
else
var counter = parseInt(table.rows[e-1].getElementsByTagName('td')[1].innerHTML)
newRow.getElementsByTagName('td')[1].innerHTML = counter + 1;
// Update the child Names
var items = newRow.getElementsByTagName("input");
for (var i = 0; i < items.length; i++) {
items[i].value = null;
items[i].name = counter + '_' + items[i].name;
}
var i = e;
while (1 <= i && !hasClass(table.rows[i], 'row-parent'))
i--;
var parent = table.rows[i].getElementsByTagName('td');
parent[0].rowSpan = counter+2;
parent[1].rowSpan = counter+2;
parent[2].rowSpan = counter+2;
var refRow = table.getElementsByTagName('tr')[e-1];
refRow.parentNode.insertBefore(newRow, refRow.nextSibling);
}
function deleteChildRow(e, tableID) {
var table = document.getElementById(tableID);
var i = e;
while (1 <= i && !hasClass(table.rows[i], 'row-parent'))
i--;
if (e-1 > i)
table.deleteRow(e-1)
}
And here's the HTML
<form action="Untitled-2.php" name="dataTable" method="post">
<table width="760" id="dataTable" border="1">
<tr>
<td width="20">
<input type="checkbox" name="chk1" />
</td>
<td width="12">1</td>
<td width="200">
<input type="text" name="txtbox1[]" />
</td>
<td width="146">
<input type="text" name="txtbox2[]" />
</td>
<td width="188">
<input type="text" name="txtbox3[]" />
</td>
</tr>
<tr class="row-parent">
<td width="22" rowspan="2">
<input type="checkbox" name="chk" />
</td>
<td width="12" rowspan="2">1</td>
<td width="149" rowspan="2">
<input type="text" name="txtbox[]" />
</td>
<td width="20">
<input type="checkbox" name="chk1" />
</td>
<td width="12">1</td>
<td width="200">
<input type="text" name="txtbox1[]" />
</td>
<td width="146">
<input type="text" name="txtbox2[]" />
</td>
<td width="188">
<input type="text" name="txtbox3[]" />
</td>
</tr>
<tr>
<td width="20"> </td>
<td width="12"> </td>
<td>
<input type="button" value="+ Child Row" onClick="addChildRow(this.parentNode.parentNode.rowIndex, 'dataTable')" />
<input type="button" value="- Child Row" onClick="deleteChildRow(this.parentNode.parentNode.rowIndex, 'dataTable')" />
</td>
<td width="146"> </td>
<td width="188"> </td>
</tr>
</table>
<input type="button" value="Add Row" onClick="addRow('dataTable')" />
<input type="button" value="Delete Row" onClick="deleteRow('dataTable')" />
</form>
And here's the CSS to hide the first row:
table tr:first-child {
display: none;
}

how to create textbox/text field and button
JavaScript
<script type="text/javascript">
function addItemTodo(){
var value = document.getElementById('item1').value;
var value2 = document.getElementById('item2').value;
var my_table = document.getElementById('todo');
var rows = my_table.getElementsByTagName("tr").length;

cell2 = row.insertCell(1);
cell1.innerHTML = value;

}
</script>
HTML Code
<input type="text" id="item1" placeholder="item1" size="12">
<input type="text" id="item2" placeholder="item2" size="14">
<button id="add" onclick="addItemTodo()">Add</button>
<table border="1" style="width:50%" id="todo">
<tr>
<th>Input from 'item1'</th>
<th>Input from 'item2'</th>
<th>Text Box</th>
<th>Button</th>
</tr>

How to append the text box and button, when clicked the add button
You could create your new elements within your Javascript as strings, and then add them to two new cells (insertCell(2) and insertCell(3)) using .innerHTML like so:
function addItemTodo() {
var value = document.getElementById('item1').value;
var value2 = document.getElementById('item2').value;
var my_table = document.getElementById('todo');
var rows = my_table.getElementsByTagName("tr").length;
var row = my_table.insertRow(rows);
row.insertCell(0).innerHTML = value;
row.insertCell(1).innerHTML = value2;
row.insertCell(2).innerHTML = "<input type='text' placeholder='xxx' class='text-box' />";
row.insertCell(3).innerHTML = "<button>Text</button>";
}
.text-box {
width: 50px;
}
<input type="text" id="item1" placeholder="item1" size="12">
<input type="text" id="item2" placeholder="item2" size="14">
<button id="add" onclick="addItemTodo()">Add</button>
<table border="1" style="width:50%" id="todo">
<tr>
<th>Input from 'item1'</th>
<th>Input from 'item2'</th>
<th>Text Box</th>
<th>Button</th>
</tr>
</table>
I have snippet in javascript that add/remove multiple rows within a table. I would like to implement the same thing into JQUERY. At the moment, the checkboxes does'nt work, but I would like them to work for the sake of userbility. I got no clue on jquery at moment. Would you help on the implementation.

Usually, when you do onSubmit="return myFunction()" it's to cancel event if myFunction returns false, continue if it returns true.
However your function returns nothing, I don't think the use of "return MyFunction()" is appropriate.
Also, in validateAllInputBoxes you test if(inputs[i].length==0) but input text object
doesn't have a length property (that I know) you should try to test inputs[i].value == null or inputs[i].value.length==0 instead.
This is my first post and I am new in PHP, i am trying to build a POS system using PHP, but i stuck in sales module.
Problem is when I scan barcode of an item, it display in textbox where i have set focus, and when i click add item button but when i repeat this step for another item(s), it remove first item and replace it with latest item, i have put my 100% but can't figure out why this is happening, that's why please help me in this regards as i know there are so many good developers in php in this forum.
Here is my code for you:
<script type="text/javascript">
function setFocus(){
document.getElementById("searchitem").focus();
}

Long story short, this is the code ( if I understood correctly what you are trying to achive ):
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(function()
{
$("#searchitem").focus().filter('input[value!=""]').addClass("orange");
});
</script>
<style type="text/css">
.orange
{
background-color: orange;
}
table#dataTable
{
empty-cells : show;
}
table#dataTable th
{
text-align : center;
background-color: #97C950;
}
.saved
{
background-color: green;
}
</style>
</head>
<body>
<form action="" method="POST" onSubmit="">
<input id="searchitem" type="text" size="75" value="" >
<input type="submit" name="search" value="New Item" >
<input id="deleteRow" type="button" value="Delete Row" >
</form>
<table style="width:98%;" id="dataTable">
<tr>
<th colspan="2" style="width:5%;">S#</th>
<th style="width:15%;">Barcode</th>
<th style="width:27%;">Item Name</th>
<th style="width:4%;">Stock</th>
<th style="width:4%;">Qty</th>
<th style="width:6%;">Price</th>
<th style="width:6%;">Disc.Rs.</th>
<th style="width:10%;">Total</th>
</tr>
</table>
<script type="text/javascript">
$('#searchitem').change(function()
{
var t = $('#dataTable');
t.append('<tr> \
<td><input type="checkbox"></td> \
<td>'+t.find('tr').length+'</td> \
<td><input size="15" type="text" value="'+$(this).val()+'"></td> \

});
function saveItem(ev)
{
// here read all rows from that row, send them via AJAX to the server to be saved
// you get the current row by looking at ev.currentTarget, something like this in Firefox
var args = [];
$(ev.currentTarget).parents('tr:first').find('input[type="text"]').each(function(){ args.push( $(this).val() ); });
$.post(
'saveItem.php',
args,
function(){ $(ev.currentTarget).addClass('saved');} /* this is triggered onSucces */
);
}
</script>
</body>
</html>
This is the long story:
you need to insert a new row in the table when you type something in input#searchitem
you don't save it in the database yet, first you insert the other columns (quantity, price etc ...)
them you hit the update button, the new row is inserted in the database and if everithing is OK the button will be colored "green"
This code is to give you a clue and to push you in the right direction (it's like a proof of concept), so here are more recomandations (hard to give beacause I still didn't understod exactly what are you trying to achive):
GLOBAL:
don't just copy/paste this code, try to undertand it, and change it for your own needs
CSS:
use external style sheet
set fixed columns width for the table
Javascript:
check if the bar code exists, highlight the row, and push it in to the visible area if is not visible (or show a box with " there are 5 more hidden rows), you can give names for the inputs like name=barcode ...
use those names in the args array to create a named array.
Hope this will help you.
I have this form code to dynamically add rows. How can I add a date dynamically?
<HTML>
<HEAD>
<TITLE> Add/Remove dynamic rows in HTML table </TITLE>
<SCRIPT language="javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
cell2.innerHTML = rowCount + 1;
var cell3 = row.insertCell(2);
var element2 = document.createElement("input");
element2.type = "text";
cell3.appendChild(element2);
}
function deleteRow(tableID) {
try {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for(var i=0; i<rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if(null != chkbox && true == chkbox.checked) {
table.deleteRow(i);
rowCount--;
i--;
}
}
}catch(e) {
alert(e);

</SCRIPT>
</HEAD>
<BODY>
<INPUT type="button" value="Add Row" onclick="addRow('dataTable')" />
<INPUT type="button" value="Delete Row" onclick="deleteRow('dataTable')" />
<TABLE id="dataTable" width="350px" border="1">

<TD><INPUT type="checkbox" name="chk"/></TD>
<TD> 1 </TD>
<TD> <INPUT type="text" /> </TD>

</TABLE>
</BODY>
</HTML>
This the code for adding row dynamically
This is the code for calendar
<script language="JavaScript" src="calendar_us.js"></script>
<link rel="stylesheet" href="calendar.css">
<INPUT type="text" name="testinput" />
<script language="JavaScript">
new tcal ({
// form name
'formname': 'testform',
// input name
'controlname': 'testinput'
});
</script>
add a new cell for example,
var cell4 = row.insertCell(3);
cell4.innerHTML = new Date();
.
<TR>
<TD><INPUT type="checkbox" name="chk"/></TD>
<TD> 1 </TD>
<TD> <INPUT type="text" /> </TD>
<TD> <INPUT type="text" name="testinput" /></TD>
</TR>
can you explain where to insert the date?
