trying to use a jQuery to remove specific text from a td

Im trying to make it so when the first column is clicked the N next to each checkbox goes away so far I have tried 2 different methods the first was nextsilbing.remove but that just removed the row I clicked on. The second method I tried was this.nextAll and removed everything but the row clicked.
[picture of table][1]
$('#table_output tbody').on('click', 'tr', function() {
console.log(table.row(this).data());
alert(JSON.stringify(table.row(this).data()));
})
$('#table_output tbody').on('click', 'td', function() {
console.log(table.cell(this).data());
while (this.nextSilbing){
this.nextSibling.remove("N")
}
alert("Test" + table.cell(this).data());
//second method
$(this).nextAll().remove("N").end().remove();
})
<table>
<tr>
<th>Carrier</th>
<th>fixed</th>
<th>mobile</th>
<th>payphone</th>
</tr>
<tr>
<td>Cat066</td>
<td><input type="checkbox" name="Fixed" ::before "N" /> </td>
<td><input type="checkbox" name="Mobile" ::before "N" /> </td>
<td><input type="checkbox" name="PayPhone" ::before "N" /> </td>
</tr>
</table> ```

I’d try to put the :before in a css class instead, and toggle the class with JQ.
// css
.input.n:before {
content: “N”;
}
// js
// assuming `this` is the input element
$(this).toggleClass('n');
Apologies if the syntax is a bit wrong, I’m on mobile ;) correct me in the comments

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>

Only one checkbox between two <td> at each <tr>

I have a code like this:
<tr>
<td>
<input type="checkbox" name="ordered[]" value="xxx"></input>
</td>
<td>
<input type="checkbox" name="inStock[]" value="yyy"></input>
</td>
</tr>
The code is repeated for each result in MySQL.
Also I'm using this code:
<script>
$('input[type="checkbox"]').on('change', function() {
// uncheck sibling checkboxes (checkboxes on the same row)
$(this).siblings().prop('checked', false);
});
</script>
I need to select only one checkbox per row (per table tr). What should I change in javascript?
Thanks!

I think you need something like this
$( document ).ready(function() {
$('input[type="checkbox"]').on('change', function() {
var checkedValue = $(this).prop('checked');
// uncheck sibling checkboxes (checkboxes on the same row)
$(this).closest('tr').find('input[type="checkbox"]').each(function(){
$(this).prop('checked',false);
});
$(this).prop("checked",checkedValue);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="checkboxes">
<tr>
<td>
<input type="checkbox" name="inStock[]" />inStock
</td>
<td>
<input type="checkbox" name="ordered[]" value="xxx" />ordered
</td>
</tr>
<tr>
<td>
<input type="checkbox" name="inStock[]" value="yyy" />inStock
</td>
<td>
<input type="checkbox" name="ordered[]" value="xxx" />ordered
</td>
</tr>
</table>

I think what you are asking for is a RadioButton. Just give them different ids but the same name and you will be able to select just one of them.

Try applying selector based on element name:
$('input[name="ordered[]"]').on('change', function() {
Or you would probably want to add some other attribute to identify the specific element you wish to select.

Since you haven't specified which sibling, say you can grab the first element out of a jQuery object using first:
$(this).siblings().first().prop('checked', false);
You can also do
$(this).siblings(".bar").eq(0).text()
You can use the eq method to reduce the matched set of elements to one at a specific index:

If you use radio buttons and use the same name for all of them, you are only able to select one radio button at a time and the other ones gets uncheked and like our friend mentioned you need to include your <td></td> tags in <tr></tr>tags.

Getting nearest text box to radio button in table

I am having trouble getting the text box nearest to my selected radio button. Here is what I have tried so far which keeps returning me 'undefined'.
HTML:
<fieldset class="capacity-field">
<legend>Capacity</legend>
<table style="margin-bottom: 20px">
<tr>
<td>
<input type="radio" name="capacity" value="raw" checked>Raw (TB):
</td>
<td>
<input type="text" name="raw-capacity" value="256" size="2"> TB
</td>
</tr>
<tr>
<td>
<input type="radio" name="capacity" value="usable">Usable (TB):
</td>
<td>
<input type="text" name="usable-capacity" value="161.28" size="2"> TB
</td>
</tr>
<tr>
<td>
<input type="radio" name="capacity" value="effective">Effective (TB):
</td>
<td>
<input type="text" name="effective-capacity" value="161.28" size="2"> TB
</td>
</tr>
</table>
JavaScript/jQuery
function cap_growth_update(toUpdate) {
var capacity = $("input[name='capacity']:checked").next("input[type='text']").val();
alert(capacity);
}
$(document).ready(function(){
cap_growth_update("T");
});
I know the value of toUpdate is arbitrary at this point, but it will be used as a selector later down the line and thus is included.

The jQuery next() function looks for a sibling element, but since these elements are separated under different td elements, you'll have to climb up the DOM:
$("input[name='capacity']:checked").closest("tr").find("input[type='text']").val();
So what it does, is to go to the closest parent, and then search for the children text input.

Try using parents() with eq() and find()
$("input[name='capacity']:checked").parents().eq(1).find("input[type='text']").val();
Note this is only a suggestion I make based on your markup, your goal could be achieved in other ways (jQuery is a rich library to traverse and manipulate DOM)

$(function() {
$("input:radio").click(function() {
if ($(this).is(":checked")) {
var value = $(this).closest("tr").find("input:text").val();
}
});
});
The code checks for a click event on a radio element then check if the element is checked, if it's checked then obtain the parent row of the radio element, find an input text inside the row an get the value of the input text the it saves the value at the var value, so you can do whatever with the value :)

How to disable tbody

I have a tbody inside which there are href/input type text/ etc
I have a code to get all elements of tbody but how to disable it.
My tbody
<tbody id="FamilyHistory_3">
<tr>
<td class="tablecell">
<a id="FamilyHistory_3" name="316098" value="316098" onclick="javascript:save('FamilyHistory_3','test');" href="#">
<img style="border-style: none" src="../images/v10/arrow_doc.png">
</a> test
</td>
</tr>
<tr>
<td>
<table>
<tbody>
<tr>
<td></td>
<td class="tablecell">
<input type="checkbox" value="Yes" name="10627_316098">Yes
<input type="checkbox" checked="" value="No" name="10627_316098">No
</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td height="2px"></td>
</tr>
</tbody>
Below is my code to get the content of tbody
function save(inputID,category){
var content= document.querySelectorAll('#tbodyID');
for(var i=0; i<content.length; i++){
// how to disable all the elements inside it
}
}

JSFiddle
document.querySelector('#tbodyID input').disabled = true;
You don't need jQuery for this.
For more than one:
JSFiddle
var l = document.querySelectorAll('#tbodyID input');
for (i = 0;i<l.length;i++)
{
l[i].disabled = true;
}

There's no need to loop, jquery can deal with groups of elements just using selectors.
Use the Jquery selectors and the prop function to add disabled="disabled" to each one.
You can also select multiple items using a comma separated list
$('#tbodyID input, #tbodyID select, ....').prop('disabled', true);
disabling an a tag will not prevent it from being clicked though. May be better to hide() these.
$('#tbodyID a').hide();

You might need to specify the types of all elements you want to disable. If you have jQuery, you can do that with something like this:
$('#tbodyID').find('a, input').prop('disabled', true);
Explanation
$('#tbodyID') : Select the element with id tbodyID
find('a, input') : Find all the a and input elements inside it
prop('disabled', true) : Set the disabled property of each element returned by the previous command

Based on your answer finally I accomplished my task using below code. I know you people have already answer but then also I am posting my answer with few addition.
Disable input
$('[id='+inputID+']').find('input').attr('disabled', true);
id of tbody
Disable click but clickable hand will be there but no request will be submitted to server
$('[id='+inputID+']').attr('onclick','').unbind('click');
id of anchor tag
Thanks,Pise
