Retrieve table row length

The 'Add' button lets the user dynamically add/remove of table rows.
I tried passing the value using hidden field but failed. How can I pass the table # of rows back to the servlet, and I also have problems getting the value from the new row created by the script. Please enlighten ASAP!
      <script language="JavaScript" type="text/javascript">
        function addRowToTable()
        var tbl = document.getElementById('albumDetailsTbl');
        var lastRow = tbl.rows.length;
        var iteration = lastRow;
        var row = tbl.insertRow(lastRow);
        // SN cell
        var cellLeft = row.insertCell(0);
        var textNode = document.createTextNode(iteration);
        cellLeft.appendChild(textNode);

in my experience, you have to write a hack that goes something like this:
declare int to hold number of rows
do db search
move cursor to last row (i forget the function call name, but you can find it)
call getRow() or something to get the row number the cursor is on
then you call findFirst or getFirst or sometihng to go back to start

How to retrieve table rows data and add into DB

Hi All,
I'm a beginner in JAVAFX, I have developed a table and adding the data into the table in multiple rows. on button click I would like these rows to be added into DB.
Please could anyone help on this. I'm copy the code for reference.
CODE:
import javafx.ext.swing.SwingComponent;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
package class TableColumn{
public var text: String;
package class TableCell{
public var text: String;
public var id;
public var str:String;
public var str1:String[];
public var num:Number;
package class TableRow{
public var cells: TableCell[];
package class SwingTable extends SwingComponent{
var table: JTable;
var model:DefaultTableModel;
public var selection: Integer;
public var columns: TableColumn[] on replace{
model = new DefaultTableModel(for(column in columns) column.text, 0);
table.setModel(model);
public var rows: TableRow[] on replace oldvalue[lo..hi] = newVals{
for(index in [hi..lo step -1]){
model.removeRow(index);
for(row in newVals){
model.addRow(for(cell in row.cells) cell.text);
public override function createJComponent(){
table = new JTable();
model = table.getModel() as DefaultTableModel;
var selectionModel = table.getSelectionModel();
selectionModel.addListSelectionListener(
ListSelectionListener{
public override function valueChanged(e: ListSelectionEvent ) {
selection = table.getSelectedRow();
return new JScrollPane(table);
}

Instead of using a combo box, using a text ring makes it much easier to disable items in the list. Here is a vi that will do what you want. Also you can delete the last element in the table and make it enabled in the text ring for selecting again.

Scripting for different numbers of table rows in cs3

As always thank you for the help.
My question: is there a simple newbie way to script for stroke placements when the numbers of rows in the category between the stroke will vary. I have not even attempted to script this style, as frankly I don't know where to start, but here is an explanation of what I need:
The table foodstuff contains:
animal, vegetable, fruit
Under animal there is:
beef, lamb, pork, poultry
Under vegetable there is:
potato, pepper, onion
Under fruit there is:
orange
If wanted a line under each category, ie after poultry, after onion, and after orange how would I go about it.
Thank you to all who have helped me so far, either by reading answers to other people's queries, or by responding directly to my own

Interesting ... I don't think there is a newbie-level answer to this challenge. It comes down to finding the first (left-to-right) cell that contains text, and adding a line on top of it all the way to the last cell in that row.
Here's a first attempt:
table = app.selection[0];
if (table.hasOwnProperty("baseline"))
table = table.parent;
if (table instanceof Cell)
table = table.parent;
if (table instanceof Column)
table = table.parent;
if (table instanceof Row)
table = table.parent;
if (table instanceof Table)
table.cells.everyItem().properties = {topEdgeStrokeWeight:0, bottomEdgeStrokeWeight:0, leftEdgeStrokeWeight:0, rightEdgeStrokeWeight:0};
table.rows.lastItem().bottomEdgeStrokeWeight = 1;
for (r=0; r<table.rows.length; r++)
for (c=0; c<table.rows[r].cells.length; c++)
   if (table.rows[r].cells[c].contents)
    for (; c<table.rows[r].cells.length; c++)
     table.rows[r].cells[c].topEdgeStrokeWeight = 1;
    break;
} else
alert ("You were supposed to be somewhere inside a Table");

How to retrieve one row from the number of records in a table

i want to retrieve the rows from the number of records in a table without using the perticular column name.

select count(*) from table
/If you have your table currently analyzed, and no changes have been made, then you could
select num_rows from user_tables where table_name = 'table'

Parametrization of Tables Name before retrieveing the Rows.

Hi all,
I have more then one tables with same number and types of attributes,
I want to create a single form to view only as per the parameter table name.
further more I want the same in Reports. i.e
Table Name : Test1, Test2.
Application ask the table name and retrieve thre rows as per parameteized name
Thanks, if any one could help

Abdul,
I don't think that you can change the table for a block in Forms at runtime. You may want to experiment with basing a block on a stored procedure so that the datasource for Forms doesn't change.
In reports you can use ref cursors to build a query on. In a before Report trigger you can determine the table name by a custom parameter.
Don't ask for example codes as I don't have some. Refer to teh Forms and Reporst documentation on how to use the techniques mentioned.

Using java to get table rows (jsp and html)?

I was wondering if there is any way to count rows from a html-table?
I want to know the number of rows created, just after it has been made. So that I can use this number 'for' creating my next table.
Have got this to work by using javascript code:
          function test2()
               if (!document.getElementsByTagName || !document.createTextNode) return;
          rows = document.getElementById('spesifikasjonsTabell').getElementsByTagName('tbody')[0].getElementsByTagName('tr');
          antallRader = rows.length;
               document.test.hoyde.value = antallRader;
               return antallRader;
, but this only generates on the clientside; which is not what I want.
I got a webpage, that uses html and jsp. After the generation of a table - which has an unknown numbers of rows, because of several underlying tests - I'd like to retrive how many rows that was generated before I proceed with my next table.
Is there a good workaround to this problem?

Hey there, and thanks for fast response.
Allready tried that code earlier. Works great on displaying the var 'row'-s inside, for instance, a <input type="text" or as a pup-up on a alert();
The javascript works on the client-side, so I have no way of using that code for further testing in codes for my viewing; at least I can't think of any.
The thing is that:
1) I can't use an 'onClick', since the next table should be generated without any human interference.
2) I used the same code to get the number of rows when I sat the table inside a form. But then, when calling the javascript function, I have no way to retrieve the linenumbers for use to test ON the next table.
Since I'd have to use, say a field name <input type hidden="rows".., a method to call this very "rows" in jsp:
<table>

</table>
<%
int numberOfRows = request.Parameter("rowcount") or what ever; here is where I need the 'number of rows'
// let's just say int here though a String
if(numberOfRows < 35)
%>
<table>

</table>
<%
else
%>

<%
%>
Any ideas?

Question about table row key

Hi,
There is a table named mytable in the JSF page. After I retrieve rows from database and execute the method on one of the rows: System.out.println(mytable.getRowKey());
the following message is printed on the Jdev console:
[oracle.jbo.Key[rrpm BK 9712 2 AAAHdMAAWAAAAfZAAG ]]
That is a composite row key. Now I want to get part of the row key like BK.
How can I get that?
Thanks
Stephen

Krithika,
Thanks for the reply.
To get part of the row key using the substring method is not practical because the length of each part of the row key may change row by row.
Any other idea to get part of a table row key precisely?
Thanks
Stephen

How to pass hidden field values on a click of a table row

hi all,
href = "bookAndNonBook.do"
I am very new to struts. I have created a table using displaytable tag which displays results in a tabular format. In addtion, i have a hidden field (prodType), the table rows are getting highlighted when i get my mouse on a particular row.
Following is the code from the results.jsp file
<body
onload="addRowHandlers('row', 'rowMouseOver')"
bgcolor="#FFFFFF" text="#000000" leftmargin="100" topmargin="50"
marginwidth="" marginheight="" rightmargin="30">
<html:form action="/bookAndNonBook" method="post">
<display:table name="sessionScope.productSearchList" id="row"
sort="list" export="true" defaultsort="1" defaultorder="ascending"
pagesize="15" decorator="org.displaytag.decorator.TotalTableDecorator"
class="dataTable">
<display:column property="prodType" title="ProdType" class="prodType"
headerClass="prodType" media="html" />
<display:column title="Title" property="titleName" sortable="true"
class="title" headerClass="title" />
</display:table>
</html:form>
</BODY>
I am calling a funtion addRowHandlers which passes the table id (which is row) and the rowMouseover for highlighting the rows on mouse over.
the code for function addRowHandlers is
function addRowHandlers(tableId, rowClassName) {
var previousClass = null;
var table = document.getElementById(tableId);
var rows = table.getElementsByTagName("tr");
for (i = 1; i < rows.length; i++) {
rows.onmouseover = function () {
previousClass = this.className;
this.className = this.className + " " + rowClassName ;
this.style.cursor="hand";
rows.onmouseout = function () {
this.className = previousClass;
this.style.cursor='';
rows.onclick = function (){
var cell = this.getElementsByTagName("td")[0];
var ProdType = cell.innerHTML;
alert("value of prodType = " + ProdType);
when i run the above code and click on a particular row it returns me the value in the hidden field i.e. prodType for that particular row
Now where i am having problem is i want that on the basis of prodType my jsp file should call different actions for different prodType as returned....somwhat a function like this
function submitProduct(prodType) {
if(prodType == "BK")
resultsForm.action = "/bookProduct.do";
else if(prodType == "NB")
resultsForm.action = "/nonbookProduct.do";
but i am unable to figure out that how do i this..
Any help will be really appreciated
Thanks
Sam

can you please suggest some good struts forums where i can post my question
thanks in advance

How to access Table rows in ADOBE form

Hello Experts,
I want to access the Table rows which are getting populated by WDA context, in form JavaScript when the table is populated.
on the basis of few cell values i want to disable and enable particular cells in table rows when the table is rendered to the user.
Please provide your inputs and suggestion on how to write a java script for it and in which event i should write the script.
i searched SDN and found couple of blogs and threads and tried using them but not working.
Thanks,
Siddharth

Hello All,
thanks for your suggestions.
after some research and trial and error i found the solution:here is the sample code for those who might face this issue.
SUPERNODE(Root Node)
    --SUBFM(SUBFORM)
MYNODE( Table)
DATA(Table ROW)
ADD       (Table COLUMNS)
DELETE   (Table COLUMNS)
var data1;
var norows = xfa.resolveNodes("SUPERNODE.SUBFM.MYNODE.DATA[*]").length;
for ( var i =0; i < norows; i++)
     if( xfa.resolveNode("SUPERNODE.SUBFM.MYNODE.DATA["i"].DELETE").rawValue == "")
    xfa.resolveNode("SUPERNODE.SUBFM.MYNODE.DATA["i"].DELETE").access = "readOnly";
    if( xfa.resolveNode("SUPERNODE.SUBFM.MYNODE.DATA["i"].ADD").rawValue != "")
    xfa.resolveNode("SUPERNODE.SUBFM.MYNODE.DATA["i"].ADD").access = "readOnly";

How can I export table row in internet explorer?

I need to export a single table row on a website and I can't figure out how to do it. The source view for the row I need is:
tr class="alt">
<td id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE</td>
<td></td>
<td></td>
<td>0.00065227</td>
<td>0.01233629</td>
<td>0.00371003</td>
</tr>I can get the table ID using the code below, but I don't know how to get the rest of the values. The table ID does not change but the numerical values do.$ie = New-Object -com InternetExplorer.Application
$ie.silent = $false
$ie.navigate2("mywebsite.com")
$ie.Document.getElementById("16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE")

Hi Tom,
this may not be quite the perfect solution, but it works for me at least. I'm not using the IE ComObject, but rather the .NET Webclient for it ...
# Load downloader function
function Get-WebContent
<#
.SYNOPSIS
Downloads a file
.DESCRIPTION
Download any file using a valid weblink and either store it locally or return its content
.PARAMETER webLink
The full link to the file (Example: "http://www.example.com/files/examplefile.dat"). Adds "http://" if webLink starts with "www".
.PARAMETER destination
The target where you want to store the file, including the filename (Example: "C:\Example\examplefile.dat"). Folder needs not exist but path must be valid. Optional.
.PARAMETER getContent
Switch that controls whether the function returns the file content.
.EXAMPLE
Get-WebContent -webLink "http://www.technet.com" -destination "C:\Example\technet.html"
This will download the technet website and store it as a html file to the target location
.EXAMPLE
Get-WebContent -webLink "www.technet.com" -getContent
This will download the technet website and return its content (as a string)
#>
Param(
[Parameter(Mandatory=$true,Position="0")]
[Alias('from')]
[string]
$WebLink,
[Parameter(Position="1")]
[Alias('to')]
[string]
$Destination,
[Alias('grab')]
[switch]
$GetContent
# Correct WebLink for typical errors
if ($webLink.StartsWith("www") -or $webLink.StartsWith("WWW")){$webLink = "http://" + $webLink}
$webclient = New-Object Net.Webclient
$file = $webclient.DownloadString($webLink)
if ($destination -ne "")
try {Set-Content -Path $destination -Value $file -Force}
catch {}
if ($getContent){return $file}
# Download website
$website = Get-WebContent -WebLink "http://www.mywebsite.com" -GetContent
# Cut away everything before the relevant part
$string = $website.SubString($website.IndexOf('<td id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">'))
# Cut away everything after the row
$string = $string.SubString(0,$string.IndexOf('</tr>'))
# Split the string into each individual line
$lines = $string.Split("`n")
# Prepareing result variable
$results = @()
# For each line, cut away the clutter
foreach ($line in $lines)
$temp = $line.SubString(4,($line.length - 10))
# for the first line, the td has an id, which this compensates for
if ($temp -like 'id="16ZwhxLjCN8fafA8wuYEnMFtGJGrFy6qcE">*'){$temp = $temp.SubString(($temp.IndexOf(">") + 1))}
# Add cleaned line to results
$results += $temp
You may need to adapt the string parsing beneath the function, if the text you posted is not literally identical to the way this function returns it. It worked for a string block acquired via copy&paste from your post anyway. :)
I certainly would be more than happy to read a more elegant version, if someone has one to offer.
Cheers,
Fred

I Need Help In Deleting Table row by clicking on "Delete" button inside the

Dear all,
first i'm new to Swing
i have created table with customized table model, i fill this table using 2d array, this table rows contains JButtons rendered using ButtonRenderer.java class and action listeners attached by the AbstractButtonEditor.java
what iam trying to do is when i click on a specified button in table row i want this row to be deleted, i found some examples that uses defaultTableModelRef.removeRow(index), but iam using customized table model and the following is my code
JTable tblPreview = new JTable();
          DbExpFormTableModel model = new DbExpFormTableModel();
          tblPreview.setModel(model);
//adding the edit button
          tblPreview.getColumn("Edit").setCellRenderer(new ButtonRenderer());
          tblPreview.getColumn("Edit").setCellEditor(new AbstractButtonEditor(new JCheckBox()));
          //adding the delete button
          tblPreview.getColumn("Delete").setCellRenderer(new ButtonRenderer());
          tblPreview.getColumn("Delete").setCellEditor(new AbstractButtonEditor(new JCheckBox()));
and here is the code of the code of my customized table model ( DbExpFormTableModel )
public class DbExpFormTableModel extends GeneralTableModel
     public DbExpFormTableModel()
          setColumnsNames();
          fillTable();
     private void setColumnsNames()
          columnNames = new String [5];
          columnNames[0] = "ID";
          columnNames[1] = "Database ID";
          columnNames[2] = "Prestatement";
          columnNames[3] = "Edit";
          columnNames[4] = "Delete";
     private void fillTable()
          int numOfRows = 2;     // = getNumberOfRows();
          data = new Object[numOfRows][5];
          data[0][0] = "1"; //we must get this value from the database, it is incremental identity
          data[0][1] = "AAA";
          data[0][2] = "insert into table 1 values(? , ? , ?)";
          data[0][3] = "Edit";
          data[0][4] = "Del";
          data[1][0] = "2"; //we must get this value from the database, it is incremental identity
          data[1][1] = "BBB";
          data[1][2] = "insert into table2 values(? , ? , ? , ?)";
          data[1][3] = "Edit";
          data[1][4] = "Del";
and this is the GeneralTableModel class
public class GeneralTableModel extends AbstractTableModel implements Serializable
     public static Object [][] data;
     public static String[] columnNames;
     //these functions should be implemented to fill the grid
     public int getRowCount()
          return data.length;
     public int getColumnCount()
          return columnNames.length;
     public String getColumnName(int col)
return columnNames[col];
     public Object getValueAt(int row , int col)
          return data[row][col];
     //i've implemented this function to enable events on added buttons
     public boolean isCellEditable(int rowIndex, int columnIndex)
          return true;
     public Class getColumnClass(int c)
return getValueAt(0, c).getClass();
public void setValueAt(Object value, int row, int col)
//fireTableDataChanged();
data[row][col] = value;
fireTableCellUpdated(row, col);
And Now what i want to do is to delete the clicked row from the table, so please help me...
thank you in advance

Hi Sureshkumar,
1. Create a value attribute named <b>select</b> of type boolean.
2. Bind the <b>checked property</b> of all the checkboxes to this attribute.
3. Create an action called <b>click</b> and bind it to <b>OnAction</b> event of the button(whose click will check all the checkboxes) and write this code in that action.
<b>wdContext.currentContextElement().setSelect(true);</b>
Warm Regards,
Murtuza

Why is it so laborious to insert table rows?

I have a table that is at least 1,000 rows in length. I've
used the shortcut Alt+A+I+R to insert a single table row, and I've
found that if I select existing rows, such as five or ten at a
time, I can insert that same number of rows in one action. However,
to insert five rows at a time, it takes about 3-5 minutes. To
insert 10 table rows at a time, it takes about 5-10 minutes.
Is there anyway I can eliminate the time lag to insert table
rows? I tried to create one new table of 1,000 rows initially, but
RoboHelp limits the table creation to 100 rows at a time.
thanks in advance,
ChristyG

Hi ChristyG
I think what you are seeing is something inherent with the
RoboHelp HTML editor. 1,000 rows is a pret-ty large table IMHO. The
RoboHelp HTML WYSIWYG editor just wasn't designed to handle things
that size. I'm just guessing here, but You probably also notice
that you can easily "type ahead" in this topic and it looks as if
you are typing i n s l o w m o t i o n.
So unfortunately, I'm going to have to say that no, there is
simply no way to "speed it up". The only possibility that comes to
mind is to use a different HTML editor for such topics. I have no
idea if Dreamweaver or other editors are up to that sort of task.
Perhaps someone with more experience with different editors can
comment on that.
Sincerely... Rick
