incrementing the value of a input field in the cloned row

1)here i'm doing clone of a row...but this code is working only in eclipse [ ie ,cloning is working ] and it is also not working in any browsers.
2)What is the solution to get the values of text boxes in the cloned rows having same name, and insert into the database using jsp and servlet?
how can i get those values with same name
3)i have servlet code to get only single value from jsp
String address_seq_num =request.getParameter("address_seq_num");
how can i get the value of address seq number in the cloned row fromjsp to servlet to insert into the next row of a table in the database.
4)if i mention "DOCUMENT TYPE" to this code ,it will not work in eclipse also.....
please guide me...
JavaScript
function clonetable() {
var x=document.getElementById("main_table"); //get the table
var rowCount = x.rows.length;
var row = document.getElementById("table_row_clone"); // find row to copy
var table = document.getElementById("table_body"); // find table to append to
var clone = row.cloneNode(true); // copy children too
var tb1 = clone.document.getElementById("asn");//here i'm incrementing the value
tb1.value=rowCount+1;//of "address seq num " in the cloned row
clone.id = "abc"; // change id or other attributes/contents
table.appendChild(clone); // add new row to end of table
}
function deltable() {
var x = document.getElementById("main_table"); //get the table
var rowCount = x.rows.length;
if (rowCount > 1) {
x.deleteRow(rowCount - 1);
} //delete the last row
}

Per your HTML (which is messy, by the way) you can increment that textbox's value with something like:
var tb = document.getElementById("asn");
tb.value = parseInt(tb.value, 10) + 1;
The trick is you have to cast the textbox's value into a number, which is what parseInt is doing in that example.
Note that the above snippet will give you "NaN" in the textbox if the value is not a valid number - it's not doing any data validation at all.

JQuery Validate dropdown selection on Button click

I'm having trouble validating a drop down asp control on button click. I have a panel that contains radio buttons, textboxes, a drop down, and a save button. If the radio button for zip is chosen a drop down list appears (that is binded with data in the code behind) and you must select a zip from the list. I'm having trouble validating on button click of the save button that a selection was made from the downdown list.
I would like to do it with jQuery and tried doing it like so that pops up and alert but its not working. Like to have it validate the selection before it does on the onClick of the button.
<script type="text/javascript">
$(document).ready(function() {
$('#btn_submit').click(function() {
if ($('#ZIPDD').val() > 0) {
return true;
}
else {
alert('Please select a zip.');
return false;
}
});
});

Binding to the dropdown in the code behind on page load
protected void Page_Load(object sender, EventArgs e)
{
if (ZIPDD.Items.Count == 0)
{
Loadzips();
}
}
private void LoadBranches()
{
using (SqlConnection SQLCONN)
{
SQLCONN.Open();
SqlCommand SQLCOMM = SQLCONN.CreateCommand();
SQLCOMM.CommandText = "SELECT * FROM table";
IDataReader dr = SQLCOMM.ExecuteReader();
ZIPDD.DataSource = dr;
ZIPDD.DataValueField = "ZIPID";
ZIPDD.DataTextField = "ZIPLABEL";
ZIPDD.DataBind();
ZIPDD.Items.Insert(0, new ListItem(String.Empty, String.Empty));
ZIPDD.SelectedIndex = 0;
}
}

When you are planning to use javascript/jquery, pay attention to how controls are rendered in the client side. You are setting visible="false" to table and controls, they will never render in the client side. You can't find them using jquery. To work properly, you need to set this:
<table runat="server" id="SHTable" visible="false" width="100%">
to this:
<table runat="server" id="SHTable" style="display:none" width="100%">
and also change this:
<asp:DropDownList runat="server" ID="ZIPDD" Visible="false"/>
to this:
<asp:DropDownList runat="server" ID="ZIPDD" style="display:none"/>
To test your script, set style="display:block" for the table and the dropdown also, otherwise you will see porpup to select a zip (dropdown value is 0).
Good luck!

Why dont you look at using the jQuery.validate plugin. It will validate all form items that have the class "required" attached to it. You could use jQuery and addClass to add the class required to the dropdown if the checkbox is highlighted.
if($('#radio_button').is(':checked')) {
$( ".dropDownClassIdentifier" ).addClass( "required" );
}
else
{
$( ".dropDownClassIdentifier" ).removeClass( "required" );
}
http://jqueryvalidation.org/ and
http://api.jquery.com/addClass/ are good places to start looking for documentation

Trying to make an html checkbox which adds a number to an output field

I am trying to create a table in which when I check a box, if the image displayed is yes.jpg, a number gets added in the output box at the bottom of the column. If not, no number gets added. There are three columns, and each checkbox affects three images and so three output boxes. Here is my code.
<html>
<head>
<script>
function onSelect(rowId)
{
var row = document.getElementById(rowId);
var checkBox = row.getElementsByTagName("checkRow")[0];
var outputRow = document.getElementById("outputRow");
var totalRow1 = outputRow.getElementById("total1");
var totalRow2 = outputRow.getElementById("total2");
var totalRow3 = outputRow.getElementById("total3");
//If box is checked, check images. If they are yes, edit boxes.
if (checkBox.checked)
if (row.getElementById.("image1").src.indexOf(yes.png) > -1)
{
totalRow1.innerHTML = "dfd";
}
else {
//checkBox =
}
}
/*function onCheck()
{
var total1 = document.getElementById("total1");
window.alert("sometext");
total1.innerHTML = "dfd";
} */
</script>
</head>
<body>
<table border="1">
<tr> <!-- Table Header -->
<td>
Checkbox
</td>
<td>
Items
</td>
<td>
Area 1
</td>
<td>
Area 2
</td>
<td>
Area 3
</td>
</tr>
<tr id="checkRow"> <!-- Row 1 -->
<td>
<form>
<input type="checkbox" name="Row1" value="Row1" onclick="onCheck();">
</form>
</td>
<td>
Item
</td>
<td id="image1">
<img src="yes.png" alt="Needed">
</td>
<td id="image2">
<img src="yes.png" alt="Needed">
</td>
<td id="image3">
<img src="no.png" alt="Needed">
</td>
</tr>
<tr id="outputRow"> <!-- Table Bottom -->
<td>
<!--Empty-->
</td>
<td>
Summation
</td>
<td id="total1">
Area 1
</td >
<td id="total2">
Area 2
</td>
<td id= "total3">
Area 3
</td>
</tr>
</table>
</body>
Currently, I am just trying to edit the output text on one of the output boxes (as seen in my onCheck() method). However, even this does not seem to work. I added an alert, which does not happen either. What am I doing wrong?

there are so many things, you are doing wrong,
firstly, you have called onCheck() function upon click on your checkbox, but there is not such javascript function. you have onSelect(id) instead.
second, you are trying to .getElementById your TDs as those ids, 'image1' and all are ids of tds and not imgs
and then you are accessing .src for them, so anyway that is wrong.
Improvements:
change your input checkbox to this:
<input type="checkbox" name="Row1" value="Row1" onchange="onCheck(this);">
what you are doing is that, you are passing reference of your input in the function onCheck(this);
2. now change your markup like this:
<td>
<form>
<input type="checkbox" name="Row1" value="Row1" onchange="onCheck(this);">
</form>
</td>
<td>
Item
</td>
<td >
<img id="image1" src="yes.png" alt="Needed">
</td>
<td >
<img id="image2" src="yes.png" alt="Needed">
</td>
<td >
<img id="image3" src="no.png" alt="Needed">
</td>
</tr>
all i've done is to provide IDs to the right elements i.e. to the IMGs, instead of TDs;
thirdly, make your onCheck() like this:
function onCheck(cb)
{
if(cb.checked===true)
{
if(document.getElementById('image1').src.toString().indexOf('yes')>0){
document.getElementById('total1').innerHTML='555';
}
else
{
document.getElementById('total1').innerHTML='No';
}
if(document.getElementById('image2').src.toString().indexOf('yes')>0){
document.getElementById('total2').innerHTML='555';
}
else
{
document.getElementById('total2').innerHTML='No';
}
if(document.getElementById('image3').src.toString().indexOf('yes')>0){
document.getElementById('total3').innerHTML='555';
}
else
{
document.getElementById('total3').innerHTML='No';
}
}
}
so basically onCheck is pretty much same as your one.
now , see this working fiddle, i've made for you, it works. ofcourse I hate the way you are doing it all. This all can be done in a much easier way.
also, learn about jQuery, it makes life easy.

redirect to another page after selecting radiobutton in mvc3

I have search box and add and edit buttons in one page.i have to edit a detail after selecting radiobutton.The script for selecting radiobutton and redirecting to next page is given below.But only alert to 'Select resume' only works.rest of code is not working.Pls help
<script type="text/javascript">
$(document).ready(function () {
var which_button;
var rad;
$('input[type="image"]').click(function (event) {
process_form_submission(event);
if (which_button == "Edit") {
if (!$("input[name='rdoUserId']:checked").val()) {
alert('Select a Resume!');
return false;
}
else {
rad = $("input[name='rdoUserId']:checked").val();
var url = "Edit/" + rad;
$('#frmIndexResume').attr("action", url);
$('#frmIndexResume').submit();
}
}
return false;
})
function process_form_submission(event) {
event.preventDefault();
//var target = $(event.target);
var input = $(event.currentTarget);
which_button = event.currentTarget.value;
}
});
</script>
<form name="frmIndexResume" method="get"action="">
<table id="tblSearch">
<tr>
<td>Name:#Html.TextBox("Names")</td>
<td>From:#Html.TextBox("FromDate")</td>
<td>To:#Html.TextBox("ToDate")</td>
<td><input type="image" value="Search" src="#Url.Content("~/images/Search.png")" width="60px"height="40px" alt="Search"/></td>
</tr>
</table>
<table id="Createbtn">
<tr>
<td>
<a href="#Url.Action("Create", "Resume")" title="Create">
<img src="#Url.Content("~/images/Create.png")" width="40px" height="30px"alt="Create"/></a>
</td>
<td>
<input type="image" value="Edit" src="#Url.Content("~/images/Edit.png")" width="40px" height="30px" alt="Edit"/>
</td>
</tr>
</table>
<table id="tblResume">
<caption>Listings</caption>
<tr>
<th>Select</th>
<th>
Name
</th>
<th>
DOB
</th>
</tr>
#foreach (var item in Model)
{
<tr>
<td>
<input type="radio" value="#item.Id" name="rdoUserId" />
</td>
<td>
#Html.DisplayFor(modelItem => item.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.DOB)
</td>
</tr>
}
</table>
</form>

You have the radio button in a loop causing there to be duplicates of the radio button.
#foreach (var item in Model)
{
...
<input type="radio" value="#item.Id" name="rdoUserId" />
...
}
The 'name' attribute is not a unique identifier. My guess is the jQuery is picking either the last or first radio button in the form since there is more than one of them.
There may be more issues besides this with the form also.

Maybe window.location is what you are looking for.
You can easily redirect via:
window.location = url;
or via:
window.navigate(url);
Please note that the second approach maybe ie-specific.

Add textbox value to listbox on tab

II am working website which is going to be accessed by a motorola device(scanner) but the functionality needs to be same a normal/usual website. On one of the page I have a textbox -> productID and listbox which can have multiple productID. Now when the focus is on textbox and it scans the productID ,the scanner returns a tab,now after this happens I need to add the textbox value to the listbox and empty the textbox and set focus on the textbox. I also should be able to delete a productId from the list.How can I achieve this using Jquery?
<table style=" width:220px;">
<tr>
<td style=" width:120px;">cost</td>
<td style=" width:100px;"><asp:TextBox ID="txt_cost" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td style=" width:120px;">Product ID</td>
<td style=" width:100px;"><asp:TextBox ID="txt_ProdID" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td style=" width:120px;">List of ProductID</td>
<td style=" width:100px;"><asp:ListBox ID="lst_ProductId" runat="server"></asp:ListBox> </td>
</tr>
<tr>
<td style=" width:120px;"><asp:Button ID="btn_Update" runat="server" Text="Update" /></td>
<td style=" width:100px;"><asp:Button ID="btn_Remove" runat="server" Text="Remove" /></td>
</tr>
</table>

$('#lst_ProductId').append($('#txt_ProdID').val());
$('#txt_ProdID').val('');
$('#txt_ProdID').focus();
Something like that should work.

$('#lst_ProductId').append($('#txt_ProdID').val()); <- set value
$('#txt_ProdID').val('');-> clrs textbox
$('#txt_ProdID').focus();->focus
$('#lst_ProductId').remove($this); ->removes
pls use blur() when pressing tabs

$(function() {
$('[id$=txt_ProdID]').keydown(function(event) {
{
if(event.keyCode == 9)
{
var textboxval = $('#txt_ProdID').val();
var lsOptNew = document.createElement('option');
lsOptNew.text = textboxval;
lsOptNew.value = textboxval;
var lsProdID = document.getElementById('lst_ProdId');
try
{
lsProdID.add(lsOptNew,null);
}
catch(ex)
{
lsProdID.add(lsOptNew);
}
$('[id$=txt_ProdID]').val('');
$('[id$=txt_ProdID]').focus();
}
}
});
});
