Add & Remove Rows From Table
Jul 20, 2005
I have written a script that adds a row to a table and moves the
values from the initial line into the new line
What I am now trying to do is add a button in each new row that will
allow me to delete the row created
I am having no luck doing this
if i add a button using createelement and assosiate code with it the
code executes when i create the row.
script as follows:
<HTML><HEAD>
<TITLE>test</TITLE>
<script LANGUAGE="JavaScript">
__uid = 0;
doc = document;
function addRowTo(id) {
var tbl = doc.getElementById(id);
//create a new row
var newrow = doc.createElement("TR");
var newcol , newinput;
newcol = doc.createElement("TD");
newcol.width = 200;
newinput = doc.createElement("input");
newinput.name = "date";
newinput.size = 20;
newinput.value = doc.main.date.value
newcol.appendChild(newinput);
newrow.appendChild(newcol);
newcol = doc.createElement("TD");
newcol.width = 200;
newinput = doc.createElement("input");
newinput.name = "start"+__uid;
newinput.size = 20;
newinput.value = doc.main.start.value
newcol.appendChild(newinput);
newrow.appendChild(newcol);
newcol = doc.createElement("TD");
newcol.width = 200;
newinput = doc.createElement("input");
newinput.name = "end"+__uid;
newinput.size = 20;
newinput.value = doc.main.end.value
newcol.appendChild(newinput);
newrow.appendChild(newcol);
tbl.appendChild(newrow);
__uid++;
document.main.date.value = ''
document.main.start.value = ''
document.main.end.value = ''
document.main.date.focus();
}
</script>
</HEAD>
<body>
<form name="main" method='post'>
<table id="tbl1">
<tbody id="tbl1body">
<td>DATE<td>START<td>END
<tr>
<td><input type='text' name='date' size=10 maxlength=200 value=""/>
<td><input type='text' name='start' size=10 maxlength=200 value=""/>
<td><input type='text' name='end' size=10 maxlength=200 value=""/>
<td>
<a href="#" onClick="addRowTo('tbl1body')">
<img border=0 src="/images/add.gif"></a>
</table>

I'm trying to build an invoice form where I don't know how many items the user will be entering. I've gotten to the point where I am able to add/remove table rows.I'd like to be able to add some functionality that will be able to check if the item entered has enough on stock on hand (in mysql table) against the value entered in a QTY box (I haven't added this in the example) and return an error message using ajax.
Code:
<HTML>
<HEAD>
<TITLE> Add/Remove dynamic rows in HTML table </TITLE>
<SCRIPT language="javascript">

When clicking on my image I can remove items that is created upon page load. But i can't remove items that I add after the page load, with the help of jQuery. My code
jQuery code:
$(document).ready(function() {
$('#addItem').click(function() {
var new_category = $('input#newCategory').val();

Below is the code that I have so far. What Im after doing is when a number is selected on the dropdown box that the number of rows with the text boxes in the table below.
In other words, if the number three is selected from the drop down, there would be three rows in the table with text boxes in. if 5 is selected then 5 rows etc.[code]...

I'm a newbie to jQuery and I'm facing a "big" problem for my actual knowledge.. code...
If I run the code and click on "Delete" what I can obtain is only a partial remove of fields (the "Label4" and "Label5" still remains on the screen, all the others are removed)... but what I really need is a complete remove all of the "two" rows... I did many search on the forum but I wasn't able to find an answer .

I am trying to add functionality to a table that allows users to add and remove table rows, but I am stuck on the JS part of it. The JS I am working with allows users to add/remove table rows that are populated with text input fields, but I want it so where the rows are populated with these elements: 1) multiple select with populated options, 2) file upload box (input type="file"). How to modify the JS below to do this (I am new to JS).
Here is the JS I am working with:
Code:
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); .....

I use the below code to add or remove a row from a table using javascript. The code works fine on IE however it doesnt work on Firefox, can anybody suggest reasons why this might be doing so?
The id "table1" is the ID of the table I am trying to insert the innerhtml into.
function addRoom()
{
var row = document.all("table1").insertRow();
var column = row.insertCell();
column.innerHTML = "input type='text' name=txt1>";

This is an example of what I currently have. There is also a button which adds more rows. It wasn't too hard to get it working using CSS and innerHTML:
<div id="main container">
<div id="row-1">
<input.....
</div>
<div id="row-2">
<input.....
</div>
etc
However, due to mass css headaches with the layout, I' like to see if it can be done it tables instead and using the DOM methods (nodes, createElement etc)
so far, the examples I've seen either don't allow the same functionality or don't work across IE5+(win), and modern versions of FFox, Safari and Netscape (MAC + WIN)
Does anyone know of a good class/example/tutorial?

I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function
LoadDestinationTable() {
$("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.

I have a need to select all table rows in the outer table of a cascading table structure, that is a table with contained tables. I tried to use the "Context" section of jQuery, but the table rows of the sub tables are being selected as well.

I have a site with 2 side by side tables with matching data. The left table is a drag-n-drop implementation so you can reorder the values in the database just by dragging and dropping. It works wonderfully. I want the right table to reflect the changes instantaneously. I got the right table to reload itself with the following jquery line:
$("#newMeet").load(location.href+" #newMeet>*","");
I stuck that line in the "Update" function of my "Sortable" funtion. And the line that I am using to initially stripe the right table is:
$(".checks2:even").addClass("grayBack");
Now matter where I stick that line, I cannot get the table re-striped after it reloads.

I have a table like this:
<table>
<tr class="item_collection_begin">
<td colspan="3"></td>
</tr>
[Code]....
To sum it up I have a rows that acts a header for a collection of item (class="item_collection_begin). Is there some way to click on a button and then all the items and their header (item_collection_begin), and their footer (item_collection_end, this is not mandatory that they have such one) are all hidden if there is no item in the collection where the cell (amount) is bigger than zero? I have got it to work for all the rows with items: $('#test .amount').filter(function (index) { return $(this).html() == 0; }).parent().remove(); But this does not hide item_collection_begin (and perhabs item_collection_end).

What I am trying to accomplish is this, I have 4 radio buttons with something different on each. Now depending on what is selected, a table shows with maybe 10 items (its very random really, could be 5, could be 50, but probably more like 20 at most), anyways. I was thinking just delete all the rows, and just recreate the table... but now after thinking about it, just make the tables invisible, and visible depending on what is selected... which is suggested, and could anyone give me hints, or show me how I would be able to accomplish this?

I'm getting an error in displayDirectors() on the line shown. What I
want to do is hide the rows in the table where rs_Board("DirStatus") =
"Retired" with hideDirectors() and show all records with
showDirectors(). What I did was create a column with a checkbox which
is not visible to the user and check this box when
rs_Board("DirStatus") = "Retired" and leave it unchecked when it
doesn't. There's probably a better way of doing this. I also want the
text in <span id="DirectorsCaption"> to change with each function but
I'm pretty sure this will work when the other error is debugged. Code:

The following code works great on Firefox and not in IE 6.
If I remove the table elements form the variable expor and just output text, the link and the form element and place a <div> with the if form the table and remove teh table it works great, if i put the div inside the table no error but nithing shows on IE. if it put as shown the id on the <table> works in firefox but not in IE I get an unknown runtime error. Is there someway around it? Becuase I want to keep the table for formating purposes as mor fields will be read and shown:
The idea is that the user insert the persons data so afertwards along with some more data it gets summited and in php i get it in DB, but a project can have none or hundres of persons, and always the names are diferent. Code:

Just playing about really, am trying to add the selected table row values to text area. Tried using childNodes but I guess it doesn't work for table rows (just comes out as '[object] - undefined'). Any better methods? - I don't really want an overly complicated solution, afterall it's just testing to get me back into JavaScript again!
<tr class="a" onclick="this.style.backgroundColor='#3D80DF' this.style.color='#FFF' document.getElementById('selected_songs').value = document.getElementById('selected_songs').value + this.childNodes[2] + ' - ' + this.childNodes[3] + '
'">
<td>1</td>
<td>Slit Wrist Theory</td>
<td>36 Crazyfists</td>
</tr>

for(var i = document.getElementById("tableId").rows.length; i > 0;i--)
{
document.getElementById("tableId").deleteRow(i -1);
}
I had to write this because it took me an hour to find out the error about deleting rows from an html table by javascript.
If you do this it generates an error :
for(var i = 0; i <document.getElementById("tableId").rows.length; i++)
{
document.getElementById("tableId").deleteRow(i -1);
}
The code above wont delete all the rows because "i" is not set back to 0 although the table rows' index will be set again beginning from zero after any row is deleted from the table.
