Dynamic row numbering using javascript

I am trying to give a dynamic row number while clicking add and delete button, but in between I delete any row it is not giving proper row_number.
My td in table(dataTable) is:
echo "<td> 1 <input type='hidden' name='task_number[]' value='1'> </td>";
ADD and delete btn :
echo "<input type='button' value='Add Task' onClick=addRow('dataTable') /> ";
echo "<INPUT type='button' value='Delete Task' onclick=deleteRow('dataTable') />";
in javascript:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length -1;
var inps = document.getElementsByName('task_number[]');
var inp=inps[rowCount-1].value; // array start from 0
inp = ++inp;
var cell2 = row.insertCell(1);
cell2.innerHTML = inp;
}
Output

use this function
function setRowNumber()
{
$('#tablename tbody tr').each(function (idx) {
$(this).children("td:eq(1)").html(idx + 1);
});
}
I also put a dynamic table code. If the checkbox is checked, that row can be deleted.
orderTable();
function addRow()
{
var rowCount = $('#example tr').length;
if(rowCount == 1)
{
var tr = "<tbody><tr id='tr'><td><input type='checkbox' id='chk' name='chk' value='chk'></td>" + "<td></td><td>Task Designer</td></tr></tbody>";
$('#example thead:last').after(tr);
}
else
{
var tr = "<tr id='tr'><td><input type='checkbox' id='chk' name='chk' value='chk'></td>" + "<td></td><td>Task Designer</td></tr>";
$('#example tr:last').after(tr);
}
orderTable();
}
function deleteRow()
{
var i = 0;
$('#example input[type=checkbox]').each(function(){
if($(this).is(":checked"))
{
$('#tr' + (i + 1)).remove();
}
i = i + 1;
});
$('#example input[type=checkbox]').each(function(){
$(this).prop('checked', false);
});
orderTable();
}
function orderTable()
{
var rowCount = $('#example tbody tr').length;
if(rowCount > 0)
{
$('#example tbody tr').each(function (idx) {
var num = idx + 1;
$(this).children("td:eq(1)").html(num);
$(this).children("td:eq(2)").html('Task Designer' + num);
$(this).attr('id','tr' + num);
//set input names
$(this).children("td:eq(0)").children().attr('id','chk' + num);
$(this).children("td:eq(0)").children().attr('name','chk' + num);
$(this).children("td:eq(0)").children().attr('value','chk' + num);
});
}
}

Add a blank row in HTML Table

I have an HTML table that adds a new row below where the button in current row is located. Currently when the row is created it generates a clone of the row above including the data. I would like this to be a row that has no entry for the input values rather than a clone of the values above.
Javascript
function addRow(row)
{
var i = row.parentNode.parentNode.rowIndex;
var tr = document.getElementById('Table').insertRow(i+1);
tr.innerHTML = row.parentNode.parentNode.innerHTML;
tr.children[0].innerHTML = tr.parentNode.querySelectorALL("tr").length-1;
}
<table id="Table" border="1">
<tr>
<td><b>Measured Depth</b></td>
<td><b>Inclination</b></td>
<td><b>Azimuth</b></td>
<td><b>Delete?</b></td>
<td><b>Add Row?</b></td>
</tr>
<tr>
<td><input size=25 type="text" id="Measured Depth0[]" contenteditable="true" value='339'></td>
<td><input size=25 type="text" id="Inclination0[]" contenteditable='true' value='0.540000021'></td>
<td><input size=25 type="text" id="Azimuth0[]" contenteditable='true' value='310.7200012'></td>
<td><input type="button" id="delbutton0" value="Delete" onclick="deleteRow(this)"/></td>
<td><input type="button" id="addmorebutton0" value="Add Row Below" onclick="addRow(this)"/></td>
</tr>
</table>

after you add a row, you can just set the values of all inputs in that row to "". get all the inputs of type text using tr.querySelectorAll("input[type='text']") and using a loop set values of all to ""
function addRow(row)
{
var i = row.parentNode.parentNode.rowIndex;
var tr = document.getElementById('Table').insertRow(i+1);
tr.innerHTML = row.parentNode.parentNode.innerHTML;
var inputs = tr.querySelectorAll("input[type='text']");
for(var i=0; i<inputs.length; i++)
inputs[i].value = "";
}
<table id="Table" border="1">
<tr>
<td><b>Measured Depth</b></td>
<td><b>Inclination</b></td>
<td><b>Azimuth</b></td>
<td><b>Delete?</b></td>
<td><b>Add Row?</b></td>
</tr>
<tr>
<td><input size=25 type="text" id="Measured Depth0[]" contenteditable="true" value='339'></td>
<td><input size=25 type="text" id="Inclination0[]" contenteditable='true' value='0.540000021'></td>
<td><input size=25 type="text" id="Azimuth0[]" contenteditable='true' value='310.7200012'></td>
<td><input type="button" id="delbutton0" value="Delete" onclick="deleteRow(this)"/></td>
<td><input type="button" id="addmorebutton0" value="Add Row Below" onclick="addRow(this)"/></td>
</tr>
</table>

You can do this very easily with jQuery:
var $lastRow = $("table#Table tr:last-child");
var $newRow = $lastRow.clone()
$newRow.find("input[type=text]").val(''); //empty all the values in text inputs
$("table#Table").append( $newRow );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="Table" border="1">
<tr>
<td><b>Measured Depth</b></td>
<td><b>Inclination</b></td>
<td><b>Azimuth</b></td>
<td><b>Delete?</b></td>
<td><b>Add Row?</b></td>
</tr>
<tr>
<td><input size=25 type="text" id="Measured Depth0[]" contenteditable="true" value='339'></td>
<td><input size=25 type="text" id="Inclination0[]" contenteditable='true' value='0.540000021'></td>
<td><input size=25 type="text" id="Azimuth0[]" contenteditable='true' value='310.7200012'></td>
<td><input type="button" id="delbutton0" value="Delete" onclick="deleteRow(this)"/></td>
<td><input type="button" id="addmorebutton0" value="Add Row Below" onclick="addRow(this)"/></td>
</tr>
</table>

Add this line of code to your function to empty values in HTML code:
function addRow(row)
{
var i = row.parentNode.parentNode.rowIndex;
var tr = document.getElementById('Table').insertRow(i+1);
tr.innerHTML = row.parentNode.parentNode.innerHTML;
tr.innerHTML = tr.innerHTML.replace(/value='.*'/, "value=''"); //this will remove all values from your html
tr.children[0].innerHTML = tr.parentNode.querySelectorALL("tr").length-1;
}

Using JQuery:
function addRow(){
var t = $("#Table tr").last().clone();
t.find("input").each(function(i,element) {
$(element).val("");
});
t.appendTo("#Table");
}

I can suggest you do this - define table rows in javascript and add those directly. Also, use th for table headers
function edit_row(no) {
document.getElementById("edit_button" + no).style.display = "none";
document.getElementById("save_button" + no).style.display = "block";
// get elements
var measured = document.getElementById("measured_row" + no);
var inclination = document.getElementById("inclination_row" + no);
var azimuth = document.getElementById("azimuth_row" + no);
// get their values
var measured_data = measured.innerHTML;
var inclination_data = inclination.innerHTML;
var azimuth_data = azimuth.innerHTML;
// replace by editable input tags
measured.innerHTML = "<input type='text' id='measured_text" + no + "' value='" + measured_data + "'>";
inclination.innerHTML = "<input type='text' id='inclination_text" + no + "' value='" + inclination_data + "'>";
azimuth.innerHTML = "<input type='text' id='azimuth_text" + no + "' value='" + azimuth_data + "'>";
}
function save_row(no) {
// same as in edit function
var measured_val = document.getElementById("measured_text" + no).value;
var inclination_val = document.getElementById("inclination_text" + no).value;
var azimuth_val = document.getElementById("azimuth_text" + no).value;
document.getElementById("measured_row" + no).innerHTML = measured_val;
document.getElementById("inclination_row" + no).innerHTML = inclination_val;
document.getElementById("azimuth_row" + no).innerHTML = azimuth_val;
document.getElementById("edit_button" + no).style.display = "block";
document.getElementById("save_button" + no).style.display = "none";
}
function delete_row(no) {
document.getElementById("row" + no + "").outerHTML = "";
}
function add_row() {
var new_measured = document.getElementById("new_measured").value;
var new_inclination = document.getElementById("new_inclination").value;
var new_azimuth = document.getElementById("new_azimuth").value;
var table = document.getElementById("data_table");
var table_len = (table.rows.length) - 1;
var row = table.insertRow(table_len).outerHTML = "<tr id='row" + table_len + "'><td id='measured_row" + table_len + "'>" + new_measured + "</td><td id='inclination_row" + table_len + "'>" + new_inclination + "</td><td id='azimuth_row" + table_len + "'>" + new_azimuth + "</td><td><input type='button' id='edit_button" + table_len + "' value='Edit' class='edit' onclick='edit_row(" + table_len + ")'> <input type='button' id='save_button" + table_len + "' value='Save' class='save' onclick='save_row(" + table_len + ")'> <input type='button' value='Delete' class='delete' onclick='delete_row(" + table_len + ")'></td></tr>";
document.getElementById("new_measured").value = "";
document.getElementById("new_inclination").value = "";

How to get checked checkbox table value in jquery

In my table I have 2 rows please see my screen shot,suppose I click first check box means I want to take that id ** and **to_area value in jquery how can do this,I tried but I can not get please help some one
$(document).ready(function() {
$('#chemist_allotment_btn').click(function() {
if ($('#chemist_allotment_form').valid()) {
$.ajax({
url: 'update_chemist_bulk_transfer.php',
type: 'POST',
data: $('form#chemist_allotment_form').serialize(),
success: function(data) {
var res = jQuery.parseJSON(data); // convert the json
console.log(res);
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function(key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td>' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td>' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});
$('#SampleDT tbody').empty().append(htmlString);
$('#get_to_area').click(function() {
var id = $('input[name=getchemist]:checked').val();
if ($(".getchemist").prop('checked') == true) {
alert(id);
alert(value.to_area);
} else {
alert('Please Check');
}
});
} else {
$('#SampleDT tbody').empty().append('No Datas Found');
}
},
});
return false;
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="well white">
<table id="SampleDT" class="datatable table table-hover table-striped table-bordered tc-table">
<thead>
<tr>
<th>Select</th>
<th>Id</th>
<th>Doctor Name</th>
<th>From Area</th>
<th>To Area</th>
<th>Address</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<center>
<div class="form-group">
<button type="button" class="btn btn-primary" style="text-align:left;" id="get_to_area">Transfer Area</button>
</div>
</center>
</div>

Firstly, add classes to each <td>, like <td class='id'>[Your id]</td>
Similarly for all the elements doctor-name, to-area, etc and a class to each <tr> like row-select
Somewhat like this:
<tr class="row-select">
<td class="select">...</td>
<td class="id">...</td>
<td class="to-area">...</td>
.
.
.
</tr>
Use jQuery like this:
$('.row-select').click(function(){
var id,toArea,checkBox;
id = $(this).find('.id').html(); //get the ID field
toArea = $(this).find('.to-area').html(); //get the to-area field
checkBox = $(this).find('.select > input');
checkbox.prop('checked',!checkbox.prop('checked'));
})
This code will get you he value no mater where you click on the row, and also invert the selection on the checkbox
To get the values of rows selected when the form is submitted run a loop like this
$('.row-select input:checked').each(function(){
var id,toArea,checkBox;
id = $(this).closest('tr').find('.id').html(); //get the ID field
toArea = $(this).closest('tr').find('.to-area').html(); //get the to-area field
})
EDIT
All together:
$(document).ready(function() {
$('#btnSubmit').click(function() {
$('.row-select input:checked').each(function() {
var id, name;
id = $(this).closest('tr').find('.id').html();
name = $(this).closest('tr').find('.name').html();
alert('ID: ' + id + " | Name: " + name);
})
})
$('#btnSelectAll').click(function() {
$('.row-select input').each(function() {
$(this).prop('checked', true);
})
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border=1>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">12</td>
<td class="name">Jones</td>
</tr>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">10</td>
<td class="name">Joseph</td>
</tr>
</table>
<button id="btnSelectAll">Select all</button>
<button id="btnSubmit">Get Value</button>

Process step-by-step:
Give the td you need some classes (from-a & to-a);
Initialize an empty array all (we'll store the data inside it later on);
Create a function that is triggered by the checkbox change
Inside the function you need to know which checkbox has changed, what's the state of it, what tr does it belong to and at the end what are the TO AREA and FROM AREA values.
If the state = checked we will add the values to the all (our small data storage);
If the state = not-checked we will remove the value from the all array;
Finally when we are done with selecting and deselecting rows by pressing the button we can get the values of the selected rows.
var all = [];
$('input[type="checkbox"]').change(function(){
var checkbox = $(this);
var state = checkbox.prop('checked');
var tr = checkbox.parents('tr');
var from = tr.children('.from-a').text();
var to = tr.children('.to-a').text();
if(state){
all.push(from + ' -> ' + to);
}else{
var index = all.indexOf(from + ' -> ' + to);
all.splice(index, 1);
}
})
$('#get_to_area').click(function(){
alert(all);
});

This is just the basic concept, you can modify it to suit your needs, I'll be happy to help you if you get stuck.

You can also use this fiddle:
In JS:
$('#get_to_area').click(function () {
var id = $('input[name=getchemist]:checked').val();
if ($('input[name=getchemist]').is(':checked')) {
var ID = $('input[name=getchemist]').parent().parent().siblings('td.chkid').html();
var TO_Area = $('input[name=getchemist]').parent().parent().siblings('td.toarea').html();
}
else {
alert('Please Check');
}
});
In Html:
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function (key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td class="chkid">' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td class="toarea">' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});

I'm guessing you need values of each td whose checbox are checked. This piece of code should get you started.
As you can see, Code loops through each checkbox which is checked, gets contents inside its corresponding td.
var Result = new Array();
$('.checkbox-custom input[type="checkbox"]:checked').each(function(){
var _this = $(this).closest('tr').find('td');
var id= $(_this).eq(0);
var name = $(_this).eq(1);
................... //Similar way for the others
Result.Push(id,name,....)
});

Delete function in JavaScript

I trying to delete row from a table but somehow is not working. Could please let me know how can I solve this one ?
here is my html with table and javascript:
<tbody class="items">
<tr>
<td> Data 1 </td>
<td> Data 2 </td>
</tr>
</tbody>
<tbody id="test">
<tr>
<td> </td>
<td> </td>
</tr>
</tbody>
$(".items tr").click(function() {
var value = parseInt($.trim(tableData[1]));
$("#test").append(
"<tr><td><input name='sm_invnumber[]' value='" +
$.trim(tableData[0]) +
"' style='width: 170px;' readonly ></td><td><input name='sm_amount[]' value='" +
$.trim(tableData[1]) +
"' style='width: 170px; text-align: right;' readonly ></td><td><span onclick='deleteRow(value, this)'> x </span> </td></tr>");
});
function deleteRow(value, row) {
var i = row.parentNode.parentNode.rowIndex;
document.getElementById('#test').deleteRow(i);
}
Here is the instruction that I am working with: Picking data by clicking on table (class= items) and place to them into table (id=test). there is a function with 'X'. I want to delete this row.
Helps are highly appreciated.

You seem to making your life very difficult. Why not simply add a class to the cell that has the cross and use jQuery to remove its containing row. For example:
<table>
<tbody id="test">
<tr><td>Data 1</td><td class="delete">x</td></tr>
<tr><td>Data 2</td><td class="delete">x</td></tr>
<tr><td>Data 3</td><td class="delete">x</td></tr>
</tbody>
</table>
$('.delete').click(function () {
$(this).parent().remove();
});
Fiddle

try this
function deleteRow(value, span)
{
$(span).closest("tr").remove();
}
or
function deleteRow(value, span)
{
var i=row.parentNode.parentNode.rowIndex;
$(document.getElementById('test')).children(":eq("+i+")").remove();
}

There are few poblems, try
jQuery(function () {
var tableData = [1, 'test'];
$(".items tr").click(function () {
var value = parseInt($.trim(tableData[1]));
$("#test").append(
"<tr><td><input name='sm_invnumber[]' value='" + $.trim(tableData[0]) + "' style='width: 170px;' readonly ></td><td><input name='sm_amount[]' value='" + $.trim(tableData[1]) + "' style='width: 170px; text-align: right;' readonly ></td><td><span onclick='deleteRow(\"" + value + "\",this)'> x </span> </td></tr>");
});
})
function deleteRow(value, row) {
$(row).closest('tr').remove();
}

JQuery make xml string from DOM model

I have a DOM with different nested divs and inputs (with values):
<div id ="div_id1">
<div id ="div_id2">
<table>
<tr>
<td>input 1:</td>
<td><input id="i1" type="text"/></td>
</tr>
<tr>
<td>input 2:</td>
<td><input id="i2" type="text"/></td>
</tr>
<tr>
<td>input 3:</td>
<td><input id="i3" type="text"/></td>
</tr>
</table>
<div id ="div_id3">
<table>
<tr>
<td>input 4:</td>
<td><input id="i4" type="text"/></td>
</tr>
<tr>
<td>input 5:</td>
<td><input id="i5" type="text"/></td>
</tr>
</table>
</div>
</div>
How to make XML string recursively according to this structure?
Like this:
<div_id1>
<div_id2>
<i1>value 1</i1>
<i2>value 2</i2>
<i3>value 3</i3>
<div_id3>
<i4>value 4</i4>
<i5>value 5</i5>
</div_id3>
</div_id2>
UPD:
I tried function like this:
function makeXml(nodes) {
var $result = $('<' + nodes.attr('id') + '>');
$.each(nodes, function(i, node) {
var nodeId = node.getAttribute('id');
var $el = $('<' + nodeId + '>').text($('#' + nodeId).val());
alert(nodeId + $('#' + nodeId).val());
$el.appendTo($result);
var $children = $(node).children();
if ($children.length > 0) {
makeXml($children).appendTo($el);
}
});
return $result;
};
But it does not work properly (does not correctly handle nested divs).
Does anyone have any solution?

One of the options (create a XML-string):
var str = '';
function makeXml(obj) {
var children = obj.children();
if (children.size() != 0) {
$.each(children, function(i, v) {
var $val = $(v), id = $val.attr('id');
if (typeof($val.attr('id')) !== "undefined") {
str += '<' + id + '>' + $('#' + id).val();
makeXml($val);
str += '</' + id + '>';
} else {
makeXml($val);
}
});
}
}
