delete rows between tables with identical tr id

I have two tables and with same tr ids and content (for some reason)!
When I click a check a box in table1 I should be able to delete that row in both table1 and table2 etc. How can I achieve this?
I can delete from table1 using
table1.on('click','tr .lowBox:checked',function(){
$(this).closest('tr').remove();
}
How do I delete row from table2.
thanks!

table1.on('click','tr .lowBox:checked',function(){
$(this).closest('tr').remove(); //send to var to perform as below
$("table2").closest('tr').remove(); //If you're traversing UP
$("table2").find('tr').remove(); //If you're traversing DOWN
//Inside your "click" event, you can traverse any part of the DOM
//regardless of where you entered the document with your click event
//slightly more robust, you could do this..
/*or as fed variables...e
var $item1 = $(this).closest('tr');
var $item2 = $("table2").closest('tr');
var $rmTwo = function(item1,item2){
$(item1).remove();
$(item2).remove();
}
//Then execute your repeatable function, using the two tr's
$rmTwo($item1,$item2);
// should remove both, and you can play
//with your jQuery to get the correct elements
//or alter them if you change your code structure.
}
This would be the closest I can get you without seeing any of your HTML, and under the assumption that you're using jQuery on your page.

As others have commented, you shouldn't have duplicate IDs. Instead you could use classes, or generate IDs that are unique (for example, by prefixing with the table id). However, if you must do it this way, here's what you could do:
table1.on('click','tr .lowBox:checked',function(){
var row = $(this).closest('tr');
table2.children("#" + row[0].id).remove();
row.remove();
}
If you switch to table-unique classes for each row:
table1.on('click','tr .lowBox:checked',function(){
var row = $(this).closest('tr');
table2.children("." + row[0].className).remove();
row.remove();
}
This solution makes a few assumptions about the structure of your HTML. I can update it if you post a more detailed sample of your HTML.

I solved this with:
table1DT=var $('#table1').dataTable({});
table2DT=var $('#table2').dataTable({});
table1DT.on('click','tr .lowBox:checked',function(){
var row= $(this).closest('tr');
//do some thing with row variable
var d=row.attr('id');
var nRow = $('#table2 tbody tr[id='+d+']')[0];
table2DT.fnDeleteRow(nRow);
table1DT.fnDeleteRow(row);
}
so checking the table1 check box would delete that particular row in table1 and table2 etc.

How to get TD from next row with same index as current TD

I have a large HTML table where all rows of the body have the same structure.
Within this table there are editable TDs (which have the class "editable" and contain a contenteditable div) and non-editable TDs (which dont't have the class "editable" and do not contain a div).
Now I am trying to get the TD from the next row that has the same index as the current (closest) TD.
The below code gives me the correct index of my current TD within its row (and looking only at editable TDs).
Can someone tell me how I can get the equivalent TD of the next row ?
My jQuery:
$(document).keydown(function(e) {
var current = $(e.target);
var editables = $(current).closest('tr').find('td.editable');
var count = editables.length;
alert( editables.index($(current).closest('td')) ); // for testing
// ...
});
Instead of the alert I am looking for something like the following:
$(current).closest('tr').next('tr').find( /* the td with class editable AND the index matching the above */ );
Example:
If I am currently on the 4th editable TD in a row I would then need the 4th editable TD in the next row.

Try using :eq() like
$(document).keydown(function(e){
var current = $(e.target);
var editables = current.closest('tr').find('td.editable');
var count = editables.length;
var index = editables.index(current.closest('td'));
current.closest('tr').next('tr').find('td:eq('+index+')');
});
As commented above, you can use current instead of $(current)

Get column and row number of the selected cell of a Flexigrid

I'm currently using a Flexigrid and I would like to recover the column number and also the row number of the selected cell.
I managed to recover the content of the selected one by adding "process: procMe" in the column model and by writing the following function :
function procMe(celDiv, id){
$(celDiv).click(function(){
var content = this.innerHTML;
}
}
But I didn't find yet how to get the column and row numbers.
Thanks for any help !

celDiv is the div inside the table cell.
Firstly, get the table cell:
var td = $(celDiv).closest('td');
Now, we use jQuery's index() method to get the relative position of that td within it's siblings
var colIndex = td.index();
colIndex should now contain the zero-based column index of that cell/header cell.
You should be able to do something similar with the row by retrieving the row, and then getting its index within its siblings:
var tr = td.closest('tr');
var rowIndex = td.index();

Deleting rows in table Javascript

I'm printing table using function:
function findL(val){
var i;
//alert(splitted + " " + JSDate);
for(i=0;i<jsData.length; i++)
{
if(jsData[i].get_date() == val)
{
$('<tr>').append($('<td>').html(jsData[i].get_startT))
.append($('<td>').html(jsData[i].get_endT))
.append($('<td>').html(jsData[i].get_prow))
.append($('<td>').html(jsData[i].get_przedm))
.append($('<td>').html(jsData[i].get_sala))
.appendTo('#pzTbody');
}
}}
As an argument function takes date from datepicker, and when I pick another date it adds to the previously viewed rows.
My problem is that I tried plenty ways to cleaning/deleting old rows before next search.
I tried deleteRow(), .parentNode in loop etc. Anyone know how to delete appended rows?

From the code I assuem pzTbody is the id of your table. To clean the table body and remove all rows do this:
$("#pzTbody").empty();
If you just want to remove the last row, use this:
$("#pzTbody tr:last-child").remove();

How do I insert a new TR into the MIDDLE of a HTML table using JQuery?

I know how to append a new row to a table using JQuery:
var newRow = $("<tr>..."</tr>");
$("#mytable tbody").append(newRow);
The question is how do I create a new row that precedes some existing row.

var newRow = $("<tr>...</tr>");
$("#idOfRowToInsertAfter").after(newRow);
The key is knowing the id of the row you want to insert the new row after, or at least coming up with some selector syntax that will get you that row.
jQuery docs on after()

where_you_want_it.before(newRow)
or
newRow.insertBefore(where_you_want_it)
-- MarkusQ

Rather than this:
$("#mytable tbody").append(newRow);
you are going to want to do something like this:
$("#id_of_existing_row").after(newRow);

With:
var newTr = $('<tr>[...]</tr>');
You can…
Insert it after (or before if you so choose) another row for which you know an ID (or whatever other property):
$('#<id of the tr you want to insert the new row after>').after(newTr)
Insert it after a particular row index (indices are 0-based, not 1-based):
$($('table#<id> tr')[<index>]).after(newTr)
…or as you mentioned, the absolute middle is possible:
var existingTrs = $('table#<id> tr')
$(existingTrs[parseInt(existingTrs.length / 2)]).after(newTr)

If for example u place an insert image into your table this will be something like this :
Your last cell in your table :
<td> <img class=\"insertRow\" src=\"/images/imgInsertRow.jpg\" /> </td>
Your jquery code :
$('table td img.insertRow').click(function(){
var newRow=$('<tr>........</tr>');
$(this).parent().parent().after(newRow);
});
