How do I append a row to a table using the prototype library.
This is part of a form so I would like to also find a way to increment the <input name="container[0]"> value. Is this possible?
if i understand you right something like this would work:
var numrows = $$('#tableid tr').length;
$('tableRow').insert({after:'<tr><td><input type="text" name="container['+numrows+']"></td></tr>'});
if you can provide more details then i'll be able to help out a bit more

I have html table in a var and need to sum each row and put total in the last cell, and put the result back to the var (I need it for further programming for SharePoint). The table has fixed rows and TDs. JS or Jquery is fine. any Ideas. thank you
here is the var:
var A1='<table Id="AEid" width="85%" border="3"><tbody>
<tr><th><b>AM1</b></th><th><b>AM2</b></th><th><b>Total</b></th>
</tr><tr><td rowspan="1"></td><td rowspan="1"></td><td rowspan="1"></td></tr>
<tr><td rowspan="1"></td><td rowspan="1"></td><td rowspan="1"></td></tr></tbody></table>';
You can just create jquery object from your var without attaching to the DOM and manipulate it to heart's content.
var newText ='<table><tbody><tr><td>1</td><td>2</td><td></td></tr><tr><td>1</td><td>2</td><td></td></tr></tbody></table>';
$newDiv = $(newText);
You can refer to the jsfiddle I made. Not the best answer, but will do what you need http://jsfiddle.net/j5pKx/4/. Hope that helps
I have a standard HTML formatted table, that dynamically generates the content, via Zend Framework. From which I have an issue altering the form internally PHP side. So I need to alter the tables appearance somehow. With that on the occasion I have an element show up in one of the rows and when this element shows up I want to break out of the table and then do something after it then start the table again.
Basically I want to inject the equivlant of
</tbody></table>/*other stuff*/<table><tbody> after the row containing the one element I seek which in this case is a label.
I tried $("label[for='theLable']").parents('tr').after('</tbody></table><br><table><tbody>') which appears to ignore the ending table parts add the br, and then does a complete open/close tag for table and tbody within the same table I am trying to break out of so inbetween tr tags basically it adds this new table
Whats the best way to approach this concept?
update with jsfiddle link

You can't really modify the HTML of the document the way you're thinking, since it's not a legitimate way to alter the DOM.
Instead, I would create a new table and .append the rows you want to move to it, which will automatically move them from their current location (instead of copying them):
$(document).ready(function() {
var $trow = $('label[for="specialLabel"]').closest('tr'),
$table = $trow.closest('table');
$('<table>').append( $trow.nextAll().andSelf() ).insertAfter($table);
});
http://jsfiddle.net/cPWDh/1/
this approach won't work in js. What you could do if the table has not too many rows is this:
var nextTable = $("table").after("/*other stuff*/<table id="nextTable"></table>");
//now you loop over the lines of your original table that you want to have after the "break", and move them to the nextTable:
var before = true;
$("table tr").each(function(){
if ($(this).has("[for='theLable']")) {
before = false;
}
if (!before) {
nextTable.append($(this));
}
});
In the JSFiddle, I am trying to generate divs dynamically using javascript. Those divs will contain tables where the last two rows can be incremented using the add button.
I have tried the code in the fiddle.
The ins_row() function is used to add rows in the table which are generated within the divs.
The addEvent() function is used to generate divs
When the Add product button is clicked a div containing a table with one row will get generated.
When the add button is clicked the last two rows should keep on getting added as per the clicks. If the remove button straight to the div is clicked the whole table and div should be deleted.
When the remove button straight to the generated rows is clicked, only that row should be deleted and not the whole div.
Problem
The problem here is the divs with table are getting generated but I couldn't figure out how to add the rows in the table.
See it in action here

Note: I have just pasted the external JS file into the javascript column of the above fiddle as I don't have the resource link.
Present output
I hope I have presented the question understandable, if anything is not clear, Please let me know
I believe I have properly understood your requirement.
Try out this fiddle http://jsfiddle.net/Kucuk/14/
It uses jquery though - its just a sample sort of thing that you could probably base your own code off. Its all doable in plain old JavaScript, if that's what you prefer. The styling is a bit off, but that you can handle I hope.
Do let me know if this helps you in some manner.
Generally, I use jQuery's appendTo() function alongwith a dummy html structure. I store this in a variable & follow it up with further attribute manipulation.
To get an idea of what I am talking about, just check this fiddle: http://jsfiddle.net/GGS4N/
This is in answer to another question Smooth out this jQuery toggle animation?. Focus on the methodology as listed below:
To create a dummy HTML structure(generic in nature).
On your desired event, triggering of population and manipulation of the dynamic elements into the dom, with giving them an identifiers and manipulating other specific attributes, and as seen in the fiddle, even animating them.
If you prefer raw JS, as seen from your code, you can implement the same functionality in raw JS too! :)
Try this fiddle to see if it works for you.
In this example, when you click on add product, all 4 textboxes are created with an add more rows and remove div buttons.
When you click on add rows, last two textboxes are created with a remove row button.
Whenever the row count of a product is more than 1, the remove div button is hidden and is shown again when the row count is 1.
Is this more like what you expected?
http://jsfiddle.net/7AeDQ/81/
I achieved this by adding styles to widen the table and the cell containing the buttons. I also changed the buttons to input type="button".
Hope this works for you.
EDIT:
I have just noticed that I mixed up your expected output and present output. Working on expected output now.
Another pure js solution
<html>
<body>
<script>
var tblCount = 0
var tblIdStr = "productTbl";
function removeRow(id, rowNumber) {
var el = document.getElementById(id);
el.deleteRow(rowNumber);
}
function addTable() {
++tblCount;
tblId = tblIdStr + tblCount;
var args = "'" + tblId + "'";
var tblHtml = '<tr><td>Product name</td><td>Price</td><td>Competitor</td><td>Price</td></tr><tr><td><input type="text"></td><td><input type="text"><td><input type="text"></td><td><input type="text"></td><td><input type="button" value="Add" onclick="addRow(' + args + ')"></td><td></td></tr>'
var tbl = document.createElement("table");
tbl.setAttribute("id", tblId);
document.getElementById("container").appendChild(tbl)
document.getElementById(tblId).innerHTML = tblHtml;
}
function addRow(id) {
var el = document.getElementById(id)
var rowCount = el.rows.length;
var row = el.insertRow(rowCount);
//console.log(row)
var args = "'" + id + "'" + "," + rowCount;
var tblRowHtml = '<td colspan=2></td><td><input type="text"></td><td><input type="text"></td><td><input type="button" value="remove" onclick="removeRow(' + args + ')"></td>';
//el.rows[rowCount].setAttribute("id", rowId);
el.rows[rowCount].innerHTML = tblRowHtml
}
</script>
<input type="button" value="Add new product table" onclick="addTable()">
<div id="container">
</div>
</body>
</html>
Sorry for the noob question: I want to create a table with input fields where the can add new ones, if they are needed. But I can'T figure out how add another input field inside a cell where another input field already exists.
My code is:
var par=obj.parentNode;
while(par.nodeName.toLowerCase()!='tr')
{ par=par.parentNode; }
// this gives me the index of the row.. works fine.
cell1=document.getElementById('avz_tabelle').rows[par.rowIndex].cells;
// this puts the content of the cells into the array "cell1"
var feld = cell1[1].createElement("input");
feld.setAttribute("name","avz_keywords" + avz_array + "[]");
feld.setAttribute("onblur","");
feld.setAttribute("type","text");
feld.setAttribute("size","30");
// Now I create a input element
// And now comes the problem:
cell1[1].appendChild(feld); // --> doesn't work
Has anyone a suggestion for me?
I got the idea to work without a table, theoratically that would work with my way. But that wouldn't be satisfying :/
If you look in a debugging console, you should see something like
TypeError: Object #<HTMLDivElement> has no method 'createElement'
Instead of creating the element from cell1[1], use document.createElement()
var feld = document.createElement("input");
You should use document.createElement("input"); instead of cell1[1].createElement("input");
As always (and as also stated in another answer here), the JavaScript console should be the first place to look for hints on what the problem is!
And wouldn't it actually be much easier if each table cell you want to add values to got a separate ID? Something containing perhaps the row index and the column index ... Then you could just select it directly.
How can i use javascript (i assume) to clone a table row like ive beautifully illustrated in the picture below?
You can hookup a live event to all the buttons. If you give them a class of clone for instance the following will work.
$('input.clone').live('click', function(){
//put jquery this context into a var
var $btn = $(this);
//use .closest() to navigate from the buttno to the closest row and clone it
var $clonedRow = $btn.closest('tr').clone();
//append the cloned row to end of the table
//clean ids if you need to
$clonedRow.find('*').andSelf().filter('[id]').each( function(){
//clear id or change to something else
this.id += '_clone';
});
//finally append new row to end of table
$btn.closest('tbody').append( $clonedRow );
});
Please Note:
If you have elements in the table row with id's you will need to do a .each through them and set them to a new value otherwise you will end up with duplicate id's in the dom which is not valid and can play havoc with jQuery selectors
You can do this like so
If you want a really simple solution, just use innerHTML:
var html = document.getElementById("the row").innerHTML;
var row = document.createElement('p');
row.innerHTML= html;
document.getElementById("table id").appendChild(row);
For what purpose do you want to use the data? I've done similar things previously on data input forms and generally I've found it to be beneficial to the users not to manipulate everything in Javascript but to hook to store the data on the server and interface with AJAX.
The issue is that as soon as you start letting users do this sort of complex table manipulation and they accidentally hit the back button you end up with a lot of disgruntled punters. Coding up transient storage on a database isn't that much harder than manipulating Javascript and in fact can be easier as you can break the operations down more easily. Debugging is simpler for that reason too (you always have inspect access to the current state of your table).
Lots of option for handling via AJAX - the simplest being to just use a place-holder division and feed the whole table structure in as needed.
A jQuery example:
$(document).ready(function(){
$('TABLE.recs').delegate('INPUT.clone','click',function(e){
e.preventDefault();
var s = $(this).parent().parent().clone().wrap('<div>').parent().html();
$('TABLE.recs TBODY TR:last').after(s);
});
});
