Show/Hide more than one <table> with a checkbox

I want to show and hide several tables on one page with one button. Unfortunately my script can only show and hide one table at a time.
I have a page with a lot of queries. There are also text fields in a table. For a better overview, the tables with the text fields should only be displayed when the checkbox is ticked. The checkbox should not be clicked at the beginning.
function Displayer(n)
{
var check = document.getElementById('Section'+n);
if (check.style.display == 'none')
{
check.style.display='inline';
}
else
{
check.style.display='none';
}
}
<p><input type="checkbox" class="btnstylega" onClick="Displayer(99)" />Show Tables</p>
<table id="Section99" style="display:none;"> <td>
AAAAAAAAAAAAAA
</td></table>
<table id="Section99" style="display:none;"> <td>
BBBBBBBBBBBBBBB
</td></table><br>
I want to show and hide many tables without adjusting the tables by clicking on the checkbox.

An ID must be unique in a document. The tool to mark multiple elements as part of a group is a class.
Replace your id attributes with class attributes.
Then replace getElementById with getElementsByClassName (or querySelectorAll).
These methods return lists of nodes and not single elements, so loop over the result like an array and access the style property on each one in turn.

The attribute id must be unique in a document, you can use class instead. You can use querySelectorAll() to target all the elements having the class, then loop through them to set the style. You can toggle the class using classList.toggle() like the following way:
function Displayer()
{
var check = document.querySelectorAll('.Section99');
check.forEach(function(table){
table.classList.toggle('show');
});
}
.Section99{
display: none;
}
.show{
display: block;
}
<p><input type="checkbox" class="btnstylega" onClick="Displayer()" />Show Tables</p>
<table class="Section99" class="hide"> <td>
AAAAAAAAAAAAAA
</td></table>
<table class="Section99" class="hide"> <td>
BBBBBBBBBBBBBBB
</td></table><br>

Improvement: It will add the event handler and trigger the change on load where needed
Note the data-attribute on the checkbox
var chg = new Event('change');
document.querySelectorAll(".btnstylega").forEach(function(but) {
but.addEventListener("change", function() {
var checked = this.checked,
section = this.getAttribute("data-tables");
document.querySelectorAll('.Section' + section).forEach(function(sect) {
sect.classList.toggle("hide",!checked);
});
})
but.dispatchEvent(chg);
});
.hide {
display: none;
}
<p><input type="checkbox" class="btnstylega" data-tables="88" checked />Show Tables 88 </p>
<p><input type="checkbox" class="btnstylega" data-tables="99" />Show Tables 99</p>
<table class="Section88">
<tr>
<td>
AAAAAAAAAAAAAA
</td>
</tr>
</table>
<table class="Section88">
<tr>
<td>
BBBBBBBBBBBBBBB
</td>
</tr>
</table><hr>
<table class="Section99">
<tr>
<td>
CCCCCCCCCCCCCCCC
</td>
</tr>
</table>
<table class="Section99">
<tr>
<td>
DDDDDDDDDDDDDDDDDDDD
</td>
</tr>
</table>

JQuery .closest("tr") is not working

http://jsfiddle.net/yjxq7bae/1/
I am trying to select the checkbox prop in the input tag. The id and name of the input tag are reused, so I have to use the <nobr> text to scale the dom and get the value.
<tr>
<td nowrap="true" valign="top" width="190px" class="ms-formlabel">
<h3 class="ms-standardheader">
<nobr>Confirmation Sent</nobr>
</h3>
</td>
<td valign="top" class="ms-formbody">
<span dir="none">
<input id="ctl00_m_g_ed53ee23_de9d_4105_ba24_00e2a21cef5e_ctl00_ctl05_ctl50_ctl00_ctl00_ctl04_ctl00_ctl00_BooleanField" type="checkbox" name="ctl00$m$g_ed53ee23_de9d_4105_ba24_00e2a21cef5e$ctl00$ctl05$ctl50$ctl00$ctl00$ctl04$ctl00$ctl00$BooleanField" checked="checked" /><br />
</span>
</td>
</tr>
<div>Click Here</div>
I have tried every conceivable way. If you will notice .closest() fails once I go up one more from the <h3> element. The fiddle demonstrates this on load by first changing the css of h3, and then attempting to hide the td.
var mop = $('nobr').filter(function () {
return $(this).text() === 'Confirmation Sent'
}).closest("tr").find("input[type=checkbox]").prop('checked');
alert(typeof mop);
$('nobr:contains(Confirmation Sent)').closest("h3").css("background", "yellow");
$('nobr:contains(Confirmation Sent)').closest("h3").closest("td").hide();
$('div').on("click ", function (event) {
var toast = $('nobr').filter(function () {
return $(this).text() === 'Confirmation Sent'
}).closest("tr").find("input[type='checkbox']").prop('checked');
alert(typeof toast);
});

The problem is that you don't have correct syntax for a table. You're missing the <table> and </table> tags around your rows.
Since it's not a valid table, the browser throws away your <tr> and <td> tags:
If you wrap your HTML in a <table> your javascript works as intended.

How to select a specific html node with a jquery selector and JavaScript?

I have the following html table:
<tbody>
<tr>
<td class="rich-tabpanel-content">
<table>
<tbody>
<tr>
<td>
<span class="bold">Overview</span>
</td>
</tr>
<tr>
<td>
<input class="titleInput" type="text"></input>
</td>
</tr>
<tr>
<td>
<span class="bold">Shorttext</span>
</td>
</tr>
<tr>
<td>
<textarea class="shorttextInput"></textarea>
</td>
</tr>
<tr>
<td>
<span class="bold">Longtext</span>
</td>
</tr>
<tr>
<td>
<textarea class="longtextInput"></textarea>
</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
Now i want to select these tags in DOM:
<span class="bold">Overview</span>
<span class="bold">Shorttext</span>
<span class="bold">Longtext</span>
I have written these line of JQuery and Java Script Code to change the value of these HTML Tags, but the command
"jQuery(value).parent().prev();"
doesn´t select the right html tag in the DOM:
jQuery('.titleInput').each(function(index, value) {
selectAndExpand(value);
}
function selectAndExpand(value) {
var captionCell = jQuery(value).parent().prev();
captionCell.empty();
var newCaption = '<span class="bold">' + "HERE IS MY NEW INPUTVALUE" + '</span>';
captionCell.append(newCaption);
};
How can i solve this problem?
It is important to navigate for example from the node
<textarea class="longtextInput"></textarea>
to
<span class="bold">Longtext</span>
or from
<input class="titleInput" type="text"></input>
to
<span class="bold">Overview</span>

Use:
$('.bold').each(function(){
$(this).html("HERE IS MY NEW INPUTVALUE")
});
Working Fiddle

With Javascript:
var elements = document.getElementsByClassName('bold');
console.log(elements[0]);
console.log(elements[1]);
console.log(elements[2]);
With jQuery:
var elements = $('.bold');
console.log(elements[0]);
console.log(elements[1]);
console.log(elements[2]);
or...
console.log($('td:contains("Overview")'));
console.log($('td:contains("Shorttext")'));
console.log($('td:contains("Longtext")'));
Cheers.

You can select them by class name (when the class name is the same, in your case "bold"):
$(".bold");
To select all textareas after them and set values to these "bold" - element use
var spans = $(".bold");
$.each(spans, function(index, item) {
var spanTd = $(item).closest("tr");
var value = $(spanTd).next().find("textarea").val();
if (value === undefined) { //if there aren't textarea - get textbox.
value = $(spanTd).next().find("input[type='text']").val();
}
$(item).html(value);
});
EDIT: Demo - http://jsfiddle.net/h9fpy/

use class selector in your case use $('.bold') to select the span class bold and you can easily navigate to prev and next like $('.bold').parent('tr').next().find('.bold'); and also give the bold class to your input elements so that we can easily navigate.

Deleting a specific row in a table

I'm trying to delete a specific row from a table using javascript. The way I'm trying to do it now, is by retrieving the ID of the current row by clicking a button (the delete button) and then deleting the row. The problem is that I'm not retrieving the current row ID in the table. If someone could help me retrieve the the ID of the current row when the user clicks the delete button, I think I can solve the rest myself. Thanks
/*The Javascript*/
function delete_row() {
alert('id goes here');
//getElementById('row').innerHTML ='hello';
//id.deleteRow();
//var table = document.getElementByTagName('items_table');
//var row = table.rows[index];
//document.getElementByTagName('items_table').deleteRow(0);
}
/*The HTML of the Table*/
<table id="items_table">
<tr id="row_1">
<td>
<input type="text" value="item1"/>
</td>
<td>
<button onclick="delete_row();">X</button>
</td>
</tr>
/* Five rows in this table... */
<tr id="row_5">
<td>
<input type="text" value="item5"/>
</td>
<td>
<button onclick="delete_row();">X</button>
</td>
</tr>
</table>

You could just ascend the tree until you find a row:
function delete_row(btn) {
var tr = btn;
while(tr && tr.nodeName != "TR") tr = tr.parentNode;
if( !tr) throw new Error("Failed to find the row, was the function called correctly?");
tr.parentNode.removeChild(tr); // delete it
}
And:
<button onClick="delete_row(this);">X</button>
The this is important, as it provides a reference to the button that was clicked, so we can find the row it is in.

Check this code. It has been verified and will do your job perfectly. :)
<script>
function delete_row(me) {
alert(me.parentNode.parentNode.id);
}
</script>
<table id="items_table">
<tr id="row_1">
<td>
<input type="text" value="item1"/>
</td>
<td>
<button onclick="delete_row(this);">X</button>
</td>
</tr>
<tr id="row_5">
<td>
<input type="text" value="item5"/>
</td>
<td>
<button onclick="delete_row(this);">X</button>
</td>
</tr>
</table>

Can't you just change <button onclick="delete_row();">X</button> to <button onclick="delete_row('row_5');">X</button>, in each row, respectively?
Your handler would look like:
function delete_row(theID) {
alert(theID);
}

Highlight/Unhighlight ONE row in a column

I have a pretty basic table at the moment:
I need to be able to only hightlight one row in each column, and deselect whatever was selected before it..
I understand I'm going to need a CSS class, e.g.
.hightlighted {
background: #f00;
color: #fff;
}
The HTML in the view is pretty basic also:
<tbody>
<tr>
<td> </td>
<td>Differdange</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Dippach</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Dudelange</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Echternach</td>
<td></td>
</tr>
<tr>
<td> </td>
<td>Erpelscheid</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Esch-sur-Alzette</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Esch-sur-Sûre</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Ettelbruck</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Feulen</td>
<td> </td>
</tr>
</tbody
But I don't know whether it's appropriate to highlight/unhighlight rows in CSS if I am going to be needing to 'grab' the selected data from the rows when the table is completed by the user?
Can anyone suggest what I should use (JQuery, Javascript, CSS) to highlight a row in a column so that I can get the data later?
EDIT
Now I've got the highlighting sorted, the only problem I'm having is differentiating between columns so that instead of this (which I'm getting atm)
I want each columns to be able to have it's own unique row highlighted (e.g. Differdange could be highlighted, as well as dddd on Localities)
Any way to edit the
$("tr").click(function() {
$("tr").removeClass("highlighted");
$(this).addClass("highlighted");
});
code to do this? Thanks

You can use the .removeClass() and .addClass() jQuery methods to achieve this. Here's a little demo: little link. The code is pretty self-explaining, but here's a commented version of the JavaScript part:
var chosen = []; //an array to save the chosen row for each column
$("td").click(function() { //when a td is clicked
var idx = $(this).index() + 1; //get column of current cell
$("td:nth-child(" + idx + ")").removeClass("highlighted"); //unhighlight all cells in column
$(this).addClass("highlighted"); //highlight this one
chosen[idx] = $(this).parent("tr").index(); //and save it as chosen in its column
});

............................
Demo
Hi now you can do this jquery as like this
Css
.hightlighted{
background: #f00;
color: #fff;
}
jquery
$("tr").click(function(){
$("tr").removeClass('hightlighted')
$(this).addClass('hightlighted');
});

Could you be more precise on when and how the selection should be made? I'm guessing you want the user to click on a row, which then gets highlighted. In that case you'd want to create a highlight class in css, add it to the row the user clicked on and later you can get the row cia its class:
tr.highlighted td {
background: #f0;
color: #fff;
}
And in the javascript:
// catch click event
$('tr').click(function (e) {
// remove prvious selection
$('tr.highlighted').removeClass('highlighted');
// make this row selected
$(e.currentTarget).addClass('highlighted');
});
// get current selection
function getSelected () {
return $('tr.highlighted');
}
