If td has value "No" add class to different td

I have the following code:
<td class="bedrag">
#_ATT{Factuur bedrag}
</td>
<td class="paid">
#_ATT{Betaald}{Ja|Nee}
</td>
In the td paid the option can be given for Yes or No. I would like change the background of bedrag depending on what was chosen in the td paid. I figured the best way to go was to addClass using Javascript. So I googled around for a while and found this piece of code:
jQuery('a:contains("Sponsored")').closest('.post-item').addClass('sponz');
I changed it to fit my needs:
$('.paid:contains("Nee")').closest('.bedrag').addClass('sponz');
But that didn't work. So I tried the following code:
$('.paid:contains("Nee")').addClass('sponz');
This adds the class sponz to the td paid. But I want to add it to bedrag. So I then tried this:
('.bedrag:has(.paid:contains("Nee"))').addClass('sponz');
But this also didn't work.
Anyone know how to get this code working so that it will add sponz the the td bedrag when a user selects the option Nee? thanks in advance!

closest() isn't quite what you need as that looks for parents. .bedrag is a sibling of .paid, so you need to use prev() instead:
$('.paid:contains("Nee")').prev('.bedrag').addClass('sponz');
.sponz { color: #C00; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td class="bedrag">bedrag 1</td>
<td class="paid">Nee</td>
</tr>
<tr>
<td class="bedrag">bedrag 2</td>
<td class="paid">Ja</td>
</tr>
<tr>
<td class="bedrag">bedrag 3</td>
<td class="paid">Nee</td>
</tr>
</table>

Can't you just do an if?
if ($('.paid:contains("Nee")').length !== 0) { // there's at least an element
// add class to the right element
}

Show rows in table with cells name attribute containing string from input (JQuery)

I would like to have keyup function that would show only rows matching the input text by cell that spans on multiple rows.
Consider following table:
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1'> dummy1 </td>
</tr>
<tr>
<td name='Key1'> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2'> dummy3 </td>
</tr>
<tr>
<td name='Key2'> dummy4 </td>
</tr>
</table>
jsfiddle
Here each row has second td tag with name that matches its "parent" column text. So when I type 'Key1' at the input field I would like it to show only dummy1 and dummy2. Is it possible in jquery?

I understand that you want to display the rows that has a matching name. If this is wrong, please elaborate more, then I can update it.
Here is a demo: https://jsfiddle.net/erkaner/gugy7r1o/33/
$('input').keyup(function(){
$('tr').hide();
$("td").filter(function() {
return $(this).text().toLowerCase().indexOf(keyword) != -1; }).parent().show().next().show();
});
});

Here's my take on your issue, assuming you always want the first column to show. https://jsfiddle.net/gugy7r1o/2/
<input type="text" id="myInput" />
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1' class="data"> dummy1 </td>
</tr>
<tr>
<td name='Key1' class="data"> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2' class="data"> dummy3 </td>
</tr>
<tr>
<td name='Key2' class="data"> dummy4 </td>
</tr>
</table>
.data{
display:none;
}
var theData = $('td.data');
var input = $('#myInput').on('keyup', function(){
theData.hide();
var value = input.val();
var matches = theData.filter('[name="'+value+'"]');
matches.show();
});

Firstly, I would recommend using <ul> to wrap each key in as tables should be used for data structure (Forgive me if that is what it is being used for).
Secondly, just attach an on keyup event to the search box and then find matches based on the id. See example below:
JS Fiddle Demo
It is also worth mentioning that it could be useful attaching a timeout to the keyup event if you end up having large amounts of rows so that only one filter is fired for fast typers!

Get the closest class from a list jquery

It's hard to explain, so I created an example:
jsfiddle
My idea is to change the color of each column when the respective input is in action...
If anyone has a better idea to do this - please let me know!
When I focus the input, I need the current class of the column.
first column input, get the class of the RED column
and the second one, get the class of the BLUE column
and so go's on...
Because if I get the class, then I can manipulate anything with this class.
the code is here:
$(".inputTest").focusin(function(){
var class = $(this).closest('.tableList')
.children().children().children('.auxClass')
.attr('class')
.split(' ')[0];
alert(class);
});
This is the main code, I try alot of stuffs to get, but nothing.
Thanks

First I'd add an outer table to split the page in a left and a right hand side. That way, the inputs below the red border and the inputs below the blue border each have their own table.
Then you can search for the first td below the closest table:
$(".inputTest").focusin(function(){
var class = $(this).closest('table').find('td:eq(0)').attr('class');
alert(class);
});
Click for working jsfiddle example.

Try this:
$(".inputTest").focus(function(){
var class = $(this).closest('table').parent().attr('class');
alert(class);
});
Edit: Oh, i just realised your inputs are not inside your tables, i think you're gonna have a hard time matching them up to the table/column they're under then. You'd need to add a common attribute to identify them by.

As mentioned in other answers your inputs are not actually in the same "columns" as your red/blue bordered tables, but you can make it so they are using the <col> element on the main table, then using the index value you can match your inputs to their column
Working Example
HTML - the only addition is the two <col> elements at the start
<table width="100%" border="1" class='tableList'>
<col span="2" class="left">
<col span="2" class="right">
<tr>
<td class="101 auxClass" width="261px" colspan="2" style="border: solid red;">
<table border="1" cellspacing="1" cellpadding="1" width="100%" height="70px">
<tbody>
<tr>
<td colspan="2">Something</td>
</tr>
<tr>
<td width="78px">Something 2</td>
<td>Total</td>
</tr>
</tbody>
</table>
</td>
<td class="102" width="261px" colspan="2" style="border: solid blue;">
<table border="1" cellspacing="1" cellpadding="1" width="100%" height="70px">
<tbody>
<tr>
<td colspan="2">
Something 3
</td>
</tr>
<tr>
<td width="78px">Something 4</td>
<td width="75px">Total 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
</tr>
<tr>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
</tr>
<tr>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
<td>Result</td>
<td><input type="text" class="inputTest"/></td>
</tr>
</table>
CSS:
col.current {background: #eee;}
jQuery
$(".inputTest").focusin(function(){
var colidx = $(this).closest('td').index();
if (colidx == 1) {
$("col").removeClass('current');
$("col.left").addClass('current');
} else if (colidx == 3) {
$("col").removeClass('current');
$("col.right").addClass('current');
}
});
Your main table is actually 4 columns, and you need to split it into two halfs of two columns each with the input being in the second column of each half
The jQuery is finding the index of the parent td of the input - there are four columns in the main table so the index of a td will either be 0,1,2 or 3 - and the input is either going to be in cell index 1 or cell index 3. When it finds out which one it add a class to the relevant col element to which you can add a background highlight..
Note though that the CSS you can apply to a col element is limited, see: http://www.quirksmode.org/css/columns.html , for the options so it would depend what you want to do
however I think from this you could probably target td index 0 & 1, or td index 2 & 3 if needed

Combining Rows in Javascript

I'm looking for some help on the Javascript angle of this problem. I have a table that goes like...
<table>
<tbody>
<tr> (Row 1)
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr> (Row 1a)
<td>
<select option>
</td>
</tr>
<tr> (Row 2)
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr> (Row 2a)
<td>
<select option>
</td>
</tr>
<tr>
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr>
<td>
<select option>
</td>
</tr>
<tbody>
</table>
There are actually more like 20 rows and row a's but I didn't think I'd want to copy them all.
I basically need to add a container row (a single row) around every two rows (# and #a). Something like:
<tr> (Container Row 1)
<td>
+<tr> (Row 1)
+<tr> (Row 1a)
</td>
</tr>
It needs to cycle through the whole table. Somehow it has to retain the HTML data inside since all of the "a"s have options.
I hope this makes sense...
Any help would be greatly appreciated, as I'm at a loss. I'm novice at best at javascript and am struggling my way through the DOM and TOM methods.
Thank you so much in advance for any help or headway.
[EDIT] For clarification, the table is already constructed from a third party database, I am editing it after it's constructed. I guess this clarifies why it would have to be javascript to be done through the DOM.

Embed another table:
<tr> (Container Row 1)
<td>
<table>
<tr><td>(Row 1a)</td></tr>
<tr><td>(Row 1b)</td></tr>
</table>
</td>
</tr>
Or if you are wanting to do that via Javascript, you can give the parent <td> an id and set it's innerHTML.
<tr> (Container Row 1)
<td id='rowX'>
</td>
</tr>
document.getElementById('rowX').innertHTML = "<table><tr><td>(Row 1a)</td></tr><tr><td>(Row 1b)</td></tr></table>";

As mentioned in another answer you can't add tr elements directly in td like you are trying.
You would first create an inner table.
If you were using jQuery you would do something like this:
//setup some click actions just to prove that they remain attached even after moving
$('#outterTable tr').click(function(){
alert('You clicked on row: '+$(this).text());
});
//update the table (group each even row with the one after it)
$('#outterTable tr:even').each(function() {
var $tr1 = $(this),
$tr2 = $tr1.next('tr'),
$t = $('<table></table>');
$('<tr></tr>').append($t).insertBefore($tr1);
//click actions will remain attached
//if that is not required, than use $tr1.remove()
$t.append($tr1).append($tr2);
});​
See this live jsFiddle example.

without jQuery it may look like that:
<script type="text/javascript">
<!--
function fx(table)
{
var tmp=document.createElement('table');
tmp.appendChild(document.createElement('tbody'))
while(table.rows.length)
{
if(table.rows.length%2==0)
{
var wrapper=tmp.lastChild.appendChild(document.createElement('tr'));
wrapper.appendChild(document.createElement('td'));
wrapper.getElementsByTagName('TD')[0].appendChild(document.createElement('table'));
wrapper.getElementsByTagName('TD')[0].lastChild.appendChild(document.createElement('tbody'));
}
wrapper.getElementsByTagName('TD')[0].lastChild.lastChild.appendChild(table.getElementsByTagName('TR')[0])
}
table.parentNode.replaceChild(tmp,table);
tmp.setAttribute('border',1);
}
window.onload=function(){fx(document.getElementsByTagName('table')[0]);}
//-->
</script>
Example#jsFiddle
But: why do you need this grouping?
If the only benefit is a visible grouping I would prefer to do this by setting the borders of the cells .
Give all cells a border and to the even a border-top:none / to the odd a border-bottom: none

How to select the <tr> which holds the <a> andchange the color

I have a table structure:
<table style="width: 100%;">
<tr>
<td>
one
</td>
<td>Two</td>
<td>Three</td>
</tr>
<tr>
<td>
Four
</td>
<td>Five</td>
<td>Six</td>
</tr>
<tr>
<td>
Seven
</td>
<td>Eight</td>
<td>Nine</td>
</tr>
</table>
CSS:
.yy
{
background-color: red;
}
Now the problem is if I click on the <a> its corresponding <tr> element (<tr> that holds the <a>) background should be red, again if I click on the same <a> it should come back to normal.
How to identify the the <tr> on which the <a> is clicked.
EDIT:
I tried:
$(".yy").not($(this).parent().parent()).removeClass("yy");
$(this).parent().parent().toggleClass("yy");
it worked.

$('a').live('click', function(){
$(this).parent().parent() //this is how you select the <tr> that the <a> is in
//first .parent() gets the <td> second .parent() gets the <tr>
});
Let me know if you need more. There might be a better way but I'm not positive.

I think closest() should get what you are looking for.
$('a').click(function() {
var tr = $(this).closest('tr');
tr.toggleClass('yy');
});
This way you do not have to assume anything about how nested the anchor is in the containing tr.
