I have looked everywhere, but my code does not work at all. I simply want to display the content of the td I'm clicking on.
I have this table:
<tr class='rowData' tooltip='{caracteristicas}'>
<td nowrap class='Body'><a href='{caracteristicas}' target="_blank" style="color:black" onClick='return confirm("VOCÊ SERÁ REDIRECIONADO PARA:\r\r {caracteristicas}")'>{inputDescItem}</a></td>
<td nowrap class='Body' align='right'>{quantidade} {hiddenCodigoItem}</td>
<td nowrap class='Body' align='center'>{grupoEstoque}</td>
<td nowrap class='Body' align='center'>{inputCodigoItem}</td>
<td nowrap class='Body' align='center'>{btnAtualizaItem}</td>
<td nowrap class='Body' align='center'><button type="button" class="btnTest">Assign</button></td>
<td nowrap class='Body' align='center' class="testNameClass" name="output" style="display:none;">{caracteristicas}</td>
</tr>
I want it so that when I click on the CLICK ME tag, it will display (in a pop-up, alert, modal or anything) the content of the below tag (that I'm not displaying).
I have the following javascript:
$("btnTest").on("click", function() {
alert($(this).closest('tr').find('testNameClass').val());
});
I'm not very good at JS so please go easy on me.
Look like you missing
$(".btnTest") instead of $("btnTest")
and just try
$(".btnTest").on("click", function() {
alert($(this).parents('tr').find('.testNameClass').val());
});
To target specific elements using a class you need to use a dot in front of the class name. In your case .btnTest and .testNameClass.
$(".btnTest").on("click", function() {
alert($(this).closest('tr').find('.testNameClass').text());
});
As you are looking for the text inside the td element you should use .text() instead of .val()
In the below example column ent_3 is hidden and you will get its values using the script mentioned above.
$(".btnTest").on("click", function() {
alert($(this).closest('tr').find('.testNameClass').text());
});
.testNameClass {
display: none;
}
table {
border-collapse: collapse;
}
th, td { border: 1px solid #000; padding: 10px; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table class="table table-bordered" id="dataTable">
<thead>
<tr>
<th>pk</th>
<th>ent_1</th>
<th>ent_2</th>
<th>ent_3</th>
</tr>
</thead>
<tbody>
<tr>
<td>PK Row 0</td>
<td>Ent_1</td>
<td><button type="button" class="btnTest">Assign</button></td>
<td class="testNameClass">Row 0 Ent_3</td>
</tr>
<tr>
<td>PK Row 1</td>
<td>Ent_1</td>
<td><button type="button" class="btnTest">Assign</button></td>
<td class="testNameClass">Row 1 Ent_3</td>
</tr>
<tr>
<td>PK Row 2</td>
<td>Ent_1</td>
<td><button type="button" class="btnTest">Assign</button></td>
<td class="testNameClass">Row 2 Ent_3</td>
</tr>
</tbody>
</table>
Your method will be handed a reference to the MouseEvent which represents details of the click. Since it is an Event, it has a currentTarget which represents an "element" in the so-called DOM ... an internal data-structure which represents the HTML. This data structure is in the form of a tree, where each node has one parent, two siblings, and some children. You can now write code to "walk up the tree" until you encounter a td node. The first one you come to is the innermost containing td.
I think you are targeting is incorrect use a . before the class name - also I see two classes in one element I set this up for you here have a look

$(".btnTest").on("click", function() {
alert($('.testNameClass').html());
});

I have several tr's which is dynamically displayed inside the tbody.
In each tr,
There is a checkbox and beside the checkbox a span. Now am trying to add a class to the span close to the checkbox on click.
I have spent couple of days but can't get the exact thing I went. The closest I did was applying q class to all the spans.
I have searched here also, yet to find the solution. This is the html.
<table id="course">
<thead class="thead">
<tr>Course</TR>
<tr>description</tr>
<tr>units</tr>
<tbody id="courses">
<!-- this is where the tr's will be displayed -->
<!--example-->
<!--Row 1-->
<tr>
<td><input type="checkbox"><span class="button is-link">MATHS</span></td>
<td>Elementary Maths</td>
<td>1</td>
</tr>
<!--Row 2-->
<tr>
<td><input type="checkbox"><span class="button is-link">SCIENCE</span></td>
<td>Elementary Bla Bla</td>
<td>1</td>
</tr>
</tbody>
</table>
This is the last code I tried to use.
$("#courses").on('change','.checkbox',function (){
$(this).closest("thead").find("span").removeClass("is-link").addClass("is-success");
});
Also tried this below, and it worked but it affected both spans.
$("#courses").on('change','.checkbox',function (){
$("#courses").find("span").removeClass("is-link").addClass("is-success");
});
I changed it to this. It's not working too
$("#courses").on('change','.checkbox',function (){
$(this). closest ("thead").find("span").removeClass("is-link").addClass("is-success");
});
These are few of what I have tried to no avail!!
Thanks for your answers in adv!!
All the jQuery is inside $(document).ready(function (){. Juss omitted it here
There's a few issues here:
The checkbox input has no .checkbox class. You need to either add the class or use the :checkbox selector instead.
The table HTML is malformed. The <thead> element needs to be closed, the tbody should be a sibling of the thead (and not a child), and the content in the thead row should be in td or th cells.
The DOM traversal logic is flawed, partially due to the malformed HTML.
To do what you require you need to just get the closest('td') and find() the target span from there. Also note that in this case you can use toggleClass() instead of separate addClass()/removeClass() calls.
With those issues corrected, the code would look something like this:
$("#courses").on('change', ':checkbox', function() {
$(this).closest('td').find("span").toggleClass("is-link is-success");
});
.is-link { color: #00C; }
.is-success { color: #0C0; }

I'm writing a user-script for a third-party website and looking to select value inside a table which has a preceding TD with a label.
Question: I'm looking to get value1 as the result, but it's selecting the containing TD as well, so I get something else too.
Limitations
Can't modify the HTML to be more query-friendly (duh, it's not my site ;)
The table has no ids (I added them for easier discussion), not even the <table> itself has an id.
The count of the rows is dynamic, so no tr:nth-child.
Tried
I found this question: Selecting an element which has another element as direct child and used the direct selector (tr:has(> td:contains), but it still selects more than needed, because the outer TD also transitively contains label1 and has a sibling.
Notice that the background I set is transparent to show that multiple TDs are selected.
$(function() {
$('#result').text($('tr:has(td:contains("label1")) > td:nth-child(2)').text())
$('tr:has(td:contains("label1"))').css("background", "rgba(255,0,0,0.3)");
});
table { border-collapse: collapse; }
table, th, td { border: 1px solid black; }
td { padding: 4px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<table>
<tr>
<td id="outer">
<table>
<tr><td id="known-info">label1</td><td id="want-to-select">value1</td></tr>
<tr><td>label2</td><td>value2</td></tr>
</table>
</td>
<td id="outer-sibling">something else</td>
</tr>
</table>
<br/>
This should be "value1": "<span id="result"></span>"
You could use :not(:has(td)) in your selector so it should be
$('td:contains("label1"):not(:has(td))').next().text()
This will select td that contains label1 text, but it will ignore parent td because it has another td inside.
var el = $('td:contains("label1"):not(:has(td))').next()
$('#result').text(el.text())
el.css('background', 'blue')

I have the following markup:
<tr>
<td>
<a>foo</a>
</td>
<td>bar</td>
<td>
<a class="delete-btn">delete</a>
</td>
</tr>
I've already hooked up a click event handler using jquery $(".delete-btn") the problem is that inside the click event handler I need the text of the first element (foo).
I'm already getting the value I need with this call:
$(this).closest("tr").children().first().children().first("a")
but I feel it's too verbose. Is there a better way to accomplish this?
I don't like this either, but... it's exactly what you're looking for:
$(this).closest("tr").find("> td:first-child > a");
You can make use of jQuery's :first pseudo-selector.
In this instance, your entire selector would be:
$('tr td:first a:first') (for the first <tr> only)
$('tr').find('td:first a:first') (for every <tr>)
Example:
$(document).ready(function(){
$('.delete-btn').click(function(){
$('tr').find('td:first a:first').hide();
})
});
table, tr, td {
border: 1px solid rgb(191,191,191);
border-collapse: collapse;
}
td {
padding: 12px;
}
.delete-btn {
cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr>
<td><a>foo</a></td>
<td>bar</td>
<td><a class="delete-btn">delete</a></td>
</tr>
<tr>
<td><a>foo</a></td>
<td>bar</td>
<td><a>baz</a></td>
</tr>

I've created a table. Now I'm trying to have an onClick event add an option where I can click the squares inside the table to select them and click again to deselect them. At the end I wish to have it to display the total amount, by that I mean that it adds together the selected squars like a calculator would do.
<style>
table, td, th {
border: 1px solid black;
}
table {
border-collapse: collapse;
}
</style>
<table>
<tr>
<td bgcolor="b8cce4">Modell</td>
<td>Trend</td>
<td>Titanum</td>
<td>Familiepakke</td>
<td>Førerassistentpakke</td>
<td>Stilpakke</td>
<td>Final price</td>
</tr>
<tr>
<td bgcolor="b8cce4"><b>Kuga</b></td>
<td>401000</td>
<td>420000</td>
<td>1000</td>
<td>10200</td>
<td>9200</td>
<td>$</td>
</tr>
<tr>
<td bgcolor="b8cce4"><b>C-max</b></td>
<td>320000</td>
<td>335000</td>
<td>1000</td>
<td>9400</td>
<td>3600</td>
<td>$</td>
</tr>
<tr>
<td bgcolor="b8cce4"><b>Focus</b></td>
<td>255000</td>
<td>325000</td>
<td>900</td>
<td>12500</td>
<td>9000</td>
<td>$</td>
</tr>
<tr>
<td bgcolor="b8cce4"><b>Mondeo</b></td>
<td>281000</td>
<td>361000</td>
<td>1100</td>
<td>9900</td>
<td>7200</td>
<td>$</td>
</tr>
I'm trying to make it so that I can click on one of the slots, able to select multiple, and at the end it will display the total price for all selected options.
I'd suggest you add/remove a class to your TD's. The "selected" can then have a different background color.
If you're using jQuery, you can use something like this (not tested):
$('td').click(function() {
$(this).toggleClass('selected');
console.log($(this).text());
});
Now you can use the CSS class to indicate it is selected.
I've added a JSFiddle here:
https://jsfiddle.net/vhwLxhsg/
I hope this is what you are looking for :-)
UPDATE:
Added calc. for each row, as requested: https://jsfiddle.net/vhwLxhsg/2/

Say I have a table:
<table id="table1" border="1">
<tr>
<td id='id1' style="width:200px"></td>
<td id='id2' style="width:200px">2222</td>
</tr>
</table>
I am using following code to add images to these table cells
$('#id1').append('<img src=images/image1.jpg />');
$('#id1').append('<img src=images/image2.jpg />');
$('#id1').append('<img src=images/image3.jpg />');
$('#id2').append('<img src=images/image4.jpg />');
Now what I want to achieve is this:
1. for cell "id2", i want the image always align to the right so it's not next to the text.
2. for cell "id1", since those 3 images has different sizes (24x24, 32x32, 24x24), i don't want them to be next to each other. what I want is that as if there are 3 small cells in that cell, each with size 32x32, and put those images into those small cells one by one.
I am not good at html or javascript. is it possible to do so?
CSS
#id2 img { float: right; }
HTML
<table id="table1" border="1">
<tr>
<td id='id1' style="width:200px"><table><tr></tr></table></td>
<td id='id2' style="width:200px">2222</td>
</tr>
</table>
Javascript
$('#id1').find('tr').append('<td><img src=images/image1.jpg /></td>');
...
Based off item #2 I'd say you're not done defining your table. You need to add a nested table in #id2 (the merits of this approach can be debated later).
So your table would be
<table>
<tr>
<td id="id1"></td>
</tr>
<tr>
<td>
<table>
<tr>
<td id="id1a"></td>
<td id="id1b"></td>
<td id="id1c"></td>
</tr>
</table>
</td>
</tr>
</table>
From there you'd append your images to the sub-cells.
