Checkboxes hide groups of rows from a table - javascript

I have a table that I would like to dynamically hide/reveal rows in, based on checkboxes at the top.
I would like to do this without jQuery, just vanilla Javascript.
I have seen numerous methods on this site and others, but always snippets of code,not complete working examples.
I don't want to give each row a separate div name, or whatever, I am assuming there is a way I can do this with a common class for the 3 types of rows I want to hide/reveal.
Can anyone please show me a working example which allows checkboxes to hide/show multiple rows from a table with vanilla Javascript?

Given HTML like the following:
<table>
<thead>
<tr>
<td>
<label>
<input type="checkbox" class="show" value="north" checked />North</label>
</td>
</tr>
<tr>
<td>
<label>
<input type="checkbox" class="show" value="south" checked />South
</label>
</td>
</tr>
<tr>
<td>
<label>
<input type="checkbox" class="show" value="outOfArea" checked />Out of area
</label>
</td>
</tr>
</thead>
<tbody>
<tr class="north">
<td>North One</td>
</tr>
<tr class="north">
<td>North Two</td>
</tr>
<tr class="outOfArea">
<td>Out-of-area One</td>
</tr>
<tr class="south">
<td>South One</td>
</tr>
<tr class="south">
<td>South Two</td>
</tr>
<tr class="north">
<td>North Three</td>
</tr>
<tr class="north">
<td>North Four</td>
</tr>
<tr class="south">
<td>South Three</td>
</tr>
<tr class="outOfArea">
<td>Out-of-area Two</td>
</tr>
</tbody>
</table>
The following jQuery seems to do as you seem to describe:
$('thead input[type=checkbox]').change(function(){
var self = this;
$(self).closest('table').find('tbody tr').filter('.' + self.value).toggle(self.checked);
});
JS Fiddle demo.
As it seems that you'd prefer a plain-JavaScript approach, I'd suggest the following (to work on the same HTML as posted above):
function toggle (e) {
var self = e.target,
toggleClass = '.' + self.value,
toToggle = document.querySelectorAll(toggleClass);
for (var i = 0, len = toToggle.length; i < len; i++) {
toToggle[i].style.display = self.checked ? 'table-row' : 'none';
}
}
var thead = document.querySelector('thead');
thead.addEventListener('change', toggle);
JS Fiddle demo.
References:
jQuery:
Attribute-equals ([attribute="value"]) selector.
change().
closest().
find().
filter().
toggle().
Plain JavaScript:
document.querySelector().
document.querySelectorAll().
EventTarget.addEventListener().

Looks like you are describing something along the lines of this example

Get row elements without using "closest" selector - jquery javascript

I have a table with 4 columns . 4th column is a button (not shown in below code). When I click on the button in a row, I want to get row elements.
I have done it using closest selector. Is there any way to find table row element "Without using closest". This is the requirement for some reason.
Please assume there is a button at end of each row
<table id="food">
<thead>
<tr>
<th>Number</th>
<th>Name</th>
<th>Type</th>
</tr>
</thead>
<tbody>
<tr class='details'>
<td>1</td>
<td>Apple</td>
<td>Fruit</td>
</tr>
<tr class='details'>
<td>2</td>
<td>Mango</td>
<td>Fruit</td>
</tr>
<tr class='details'>
<td>3</td>
<td>Grape</td>
<td>Fruit</td>
</tr>
</tbody>
</table>
Here is the existing code, I need to replace closest. It will be awesome if I can use class names like $(this).somethin('.details');
$('#button1').click(function(){
var row = $(this).closest('tr');
//Do some stuff
})
Thanks
Use parents() and pass a class selector like
$('#button1').click(function(){
var row = $(this).parents('.details');
//Do some stuff
})
Note, you could also use closest in this case and pass the class selector
var row = $(this).closest('.details');

How to use Javascript to make several rows in an HTML table invisible

I have an HTML table and there are several rows in that table that I want to toggle to either be visible or invisible as a group. Since I can't simply put a <div> around them, what would be a good way to 'group' them together.
try making your html in such a way you can hide/visible and apply your css/js.
<table>
<tr class="visible"><td></td></tr>
<tr class="visible"><td></td></tr>
<tr class="hidden"><td></td></tr>
<tr class="visible"><td></td></tr>
<tr class="visible"><td></td></tr>
<tr class="hidden"><td></td></tr>
<tr class="visible"><td></td></tr>
</table>
You can group them in separate <tbody> elements (since you can't use <div> elements, as you stated).
<table id="mytable">
<tbody>
<!-- some rows to group -->
</tbody>
<tbody>
<!-- some rows to group -->
</tbody>
<tbody>
<!-- some rows to group -->
</tbody>
</table>
Then select the tbody you want.
var table = document.getElementById("mytable");
table.tBodies[1].style.display="none";
You could use the tbody tag. You can set the id attribute on it.
tbody id="customer1"
<table>
<thead>
<tr><th>Customer</th><th>Order</th><th>Month</th></tr>
</thead>
<tbody id="customer1">
<tr><td>Customer 1</td><td>#1</td><td>January</td></tr>
<tr><td>Customer 1</td><td>#2</td><td>April</td></tr>
<tr><td>Customer 1</td><td>#3</td><td>March</td></tr>
</tbody>
<tbody id="customer2">
<tr><td>Customer 2</td><td>#1</td><td>January</td></tr>
<tr><td>Customer 2</td><td>#2</td><td>April</td></tr>
<tr><td>Customer 2</td><td>#3</td><td>March</td></tr>
</tbody>
<tbody id="customer3">
<tr><td>Customer 3</td><td>#1</td><td>January</td></tr>
<tr><td>Customer 3</td><td>#2</td><td>April</td></tr>
<tr><td>Customer 3</td><td>#3</td><td>March</td></tr>
</tbody>
</table>
Then with JQuery you can easily hide/show.
I would recommend a jQuery solution to you. Provide all of your <tr> tags a common class and a unique id (for individual selection). Then you can use jQuery to grab them.
$('tr .commonClass').css("display", "none");
You could also just swap classes with the individual ids
$('#someTR').removeClass("visibleClass");
$('#someTR').addClass("invisibleClass");
Note: For the record I prefer #Yograj Gupta's method, but he beat me to the punch posting.
Pure JavaScript jsfiddle
<table>
<tr class="show"><td></td></tr>
<tr class="show"><td></td></tr>
<tr class="hide"><td></td></tr>
<tr class="show"><td></td></tr>
<tr class="show"><td></td></tr>
<tr class="hide"><td></td></tr>
<tr class="show"><td></td></tr>
</table>
JS:
var trGroup = document.getElementsByClassName("hide");
for(var k=0; k < trGroup.length; k++){
trGroup[k].style.display = "none";
}
Place a common class on the rows which you want to group. than work on that like
or you have some set of rules for visible or hidden, rows group you can simple use css + javascript like
HTML
<table id="myGroupTab">
<tr class="group1"><td> </td></tr>
<tr class="group1"><td> </td></tr>
<tr class="group2"><td> </td></tr>
<tr class="group2"><td> </td></tr>
<tr class="group1"><td> </td></tr>
</table>
you can write some css rules like
CSS
#myGroupTab.showGrp1 .group1{ display:block;}
#myGroupTab.showGrp1 .group2{ display:none;}
#myGroupTab.showGrp2 .group1{ display:none;}
#myGroupTab.showGrp2 .group2{ display:block;}
You can use Javascript like
JS
document.getElementById('myGroupTab').className = "showGrp1"; //To Show Only tr.group1
document.getElementById('myGroupTab').className = "showGrp2"; //To Show Only tr.group2
Its even simple to make display none or block applying a class on parent, instead of looping every tr...
Or by jQuery you can achieve this, make them visible or hidden using jQuery.
$("tr.group1").hide() or $("tr.group2").show()
#user1689607 solution using multiple tbody(s) in table is also a good solution.

Javascript Hide Column by Default

After browsing online for tutorials on Javascript show/hide I could only find examples on where all the columns were by default visible. I'm looking for a way to have some columns hidden by default (and allow them to be toggled on via a checkbox) and to have some columns shown by default (and allow them to be toggled off via a checkbox).
Is this possible?
For reference my table structure is as follows:
<table>
<thead>
<tr>
<th>Name</th>
<th>Job</th>
</tr>
</thead>
<tbody>
<tr>
<td>Mike</td>
<td>Dancer</td>
</tr>
</tbody>
</table>
Pure javascript:
HTML
<input type="checkbox" onclick="showhide(1, this)" checked="checked" /> Name<br />
<input type="checkbox" onclick="showhide(3, this)" checked="checked" /> Job<br />
JS
function showhide(column, elem){
if (elem.checked)
dp = "table-cell";
else
dp = "none";
tds = document.getElementsByTagName('tr');
for (i=0; i<tds.length; i++)
tds[i].childNodes[column].style.display = dp;
}
Pure JS fiddle example
Please consider using a javascript library as JQuery for such trivial things. You code could be as simple as:
​
HTML
<input type="checkbox" data-col="1" checked="checked" /> Name<br />
<input type="checkbox" data-col="2" checked="checked" /> Job<br />
jQuery JS:
$(function(){
$(':checkbox').on('change', function(){
$('th, td', 'tr').filter(':nth-child(' + $(this).data('col') + ')').toggle();
});
});
jQuery Fiddle example
Here's the toggle function (using jQuery):
function toggleColumns(column, state) {
var cells = $("table").find("th, td").filter(":nth-child(" + column + ")");
if (state)
cells.hide();
else
cells.show();
}
If you need that column hidden by default, you can call this function during onLoad.
Example http://jsfiddle.net/nynEd/
in your css you should have something like
.hidden{
display:none;
}
.shown{
display:block;
}
then in your html you should have something like
<table>
<thead>
<tr>
<th id="th1" class="shown">Name</th>
<th id="th2" class="shown">Job</th>
</tr>
</thead>
<tbody>
<tr>
<td id="td1" class="shown">Mike</td>
<td id="td2" class="shown">Dancer</td>
</tr>
</tbody>
</table>
you then have to implement a togle method that will change the visibility of the column
//id should be passhed as 1, 2, 3 so on...
function togleTable(id){
if(document.getElementById("th"+id).className == "shown"){
document.getElementById("th"+id).className = "hidden";
}
if(document.getElementById("td"+id).className == "shown"){
document.getElementById("td"+id).className = "hidden";
}
if(document.getElementById("th"+id).className == "hidden"){
document.getElementById("th"+id).className = "shown";
}
if(document.getElementById("td"+id).className == "hidden"){
document.getElementById("td"+id).className = "shown";
}
}
and then in the compobox onChange() event you should call the togleTable function passing as id the number of the row you want to show/hide
this is a good place to start i think.
Have fun
UPDATED
if you want to have more than one class for your rows dont forget you can also use this:
document.getElementById('id').classList.add('class');
document.getElementById('id').classList.remove('class');
There are many way out for this my option is using basic jquery functions like,
<input type="checkbox" id="opt1" checked/>col 1
<input type="checkbox" id="opt2"/>col 2
<table border="1" cellpadding="5">
<thead>
<tr>
<th>Name</th>
<th>Job</th>
<th id="col1">col 1</th>
<th id="col2">col 2</th>
</tr>
</thead>
<tbody>
<tr>
<td>Mike</td>
<td>Dancer</td>
<td class="data1">data 1</td>
<td class="data2">data 2</td>
</tr>
</tbody>
</table>​
This is your HTML code,
$(document).ready(function() {
if($("#opt1").is(":checked")){
$("#col1").show();
$(".data1").show();
}else{
$("#col1").hide();
$(".data1").hide();
}
if($("#opt2").is(":checked")){
$("#col2").show();
$(".data2").show();
}else{
$("#col2").hide();
$(".data2").hide();
}
$("#opt1").live('click', function() {
if($("#opt1").is(":checked")){
$("#col1").show();
$(".data1").show();
}else{
$("#col1").hide();
$(".data1").hide();
}
});
$("#opt2").live('click', function() {
if($("#opt2").is(":checked")){
$("#col2").show();
$(".data2").show();
}else{
$("#col2").hide();
$(".data2").hide();
}
});
});​
This is a java-script code.
Please find working example
The columns which you want to hide should have attribute style="display:none" initially

Hide second and third row of table

<div class="NewsResultsList">
<table>
<tr>
<td>
Results:<br/>
First<br/>
Second
</td>
</tr>
<tr>
<td>
</td>
</tr>
<tr>
<td>No Results</td>
</tr>
</table>
</div>
I need to hide the second row and the third row.
$('div.NewsResultsList table tr:eq(1)').hide();
$('div.NewsResultsList table tr:eq(2)').hide();
That didn't do it? What is wrong?
Here are a couple of ways to do it:
jsBin demo
$('.NewsResultList tr:gt(0)').hide();
$('.NewsResultList tr').slice(-2).hide();
$('.NewsResultList tr').not(':eq(0)').hide();
$('.NewsResultList tr td:contains("No")').parent('tr').hide();
$('.NewsResultList tr').not(':first').hide();
$('.NewsResultList tr').eq(-1).hide().end().eq(-2).hide();
$('.NewsResultList tr:last').prev().andSelf().hide();
Use this Script:
<script type="text/javascript">
$(document).ready(function (e) {
$('.NewsResultsList tr:eq(1)').hide();
$('.NewsResultsList tr:eq(2)').hide();
});
</script>
You spelled NewsResultList wrong in your jQuery call. ("NewsResultsList")... ;)
You have wrong selctors to get to that table rows:
It should actually be
$('div table tr:eq(1)').hide();
$('div table tr:eq(2)').hide();
DEMO
Two issues:
You have NewsResultsList in your selector, but the class is NewsResultList. The two don't match.
And, you are missing a </td> in the table.
Fix those two issues and it works here: http://jsfiddle.net/jfriend00/pfemk/
Try this for in your html/PHP:
<table>
<tr>
<td>
Results:<br/>
First<br/>
Second
</td>
</tr>
<tr class="hideMe">
<td> </td>
<td></td>
</tr>
<tr class="hideMe">
<td>No Results</td>
</tr>
</table>
</div>
and this in your jQuery/javascript:
$('#something').click( function() {
$('.hideMe').hide();
});

Copy cell value from table to textbox

I have the following table. I want to copy Id value on the seleced row to the text box. If I click on link "Select" in the first row the text box value will 0001.
If the table needs modification to get result better and faster, please leave your suggestion.
<div>
<input id="selectedId" type="text" />
</div>
<table cellspacing="1" class="tablesorter" id="nameList">
<thead>
<tr>
<th class="header">Name</th>
<th class="header">Id</th>
<th class="header">Gender</th>
<th>Select</th>
</tr>
</thead>
<tbody>
<tr>
<td>Akom Smith</td>
<td>0001</td>
<td>M</td>
<td>Select</td>
</tr>
<tr>
<td>Amara Sahara</td>
<td>0002</td>
<td>F</td>
<td>Select</td>
</tr>
<tr>
<td>John Lache</td>
<td>0003</td>
<td>M</td>
<td>Select</td>
</tr>
</tbody>
</table>
try this,
$('a.click-to-select').click(function() {
var id = $(this).closest('tr').find('td').eq(1).text();
$('#selectedId').val(id);
return false;
});​
simple cool demo
added notes for the comment below.
$('a.click-to-select').click(function() {
var id = $(this).closest('tr').find('td.id').text();
$('#selectedId').val(id);
return false;
});​
updated demo
Well, you know your key is the second td in the row. You can use the :nth-child selector like this:
<script type="text/javascript">
var getUniqueId = function() {
return $('td:nth-child(2)').text();
}
</script>
Of course you need a way to identify the correct , but I assume the code is supposed to be called from each and there you can use the parent selector.
Otherwise I'd put an id attribute in each row to make selecting easier.
