I have a table where a row gets added every time I press a "Add" button. I have an "Edit" button which is placed in the first cell of the newly created row.
I want to highlight the row that is being edited. I know that I can get the current <tr> element like
var par = $(this).parent().parent();
But when I use,
par.css('border-color', 'red');
It does not change the color.
What mistake am I making and how should I highlight that particular row?
This is really about the styling of the <tr>. CSS doesn't like to style <tr>'s because they really only exist for semantics. In order to add a border to one, you need to make it display: block;.
Here is a jsFiddle and example code.
HTML
<table>
<tbody>
<tr><td>Some Content</td></tr>
<tr><td>Some Content</td></tr>
<tr>
<td>
Edit
</td>
</tr>
<tr><td>Some Content</td></tr>
<tr><td>Some Content</td></tr>
</tbody>
</table>
Javascript
$(".edit").click(function(e) {
$(this).closest('tr').toggleClass('editting');
e.preventDefault();
});
CSS
table tr {
display: block;
border: 1px solid rgba(0, 0, 0, 0);
}
.editting {
background: #FAA;
border: 1px solid red;
}
Please note how I used an rgba color to make the border opaque. There are other ways to do this, but if you leave the border off it causes the table to "jitter."
Assuming this refers to an element within the tr, then it will be better to use .closest() here
var par = $(this).closest('tr')

I have a table with multiple lines, e.g.:
<table>
<tr id="line1"><td>Line</td><td>1</td></tr>
<tr id="line2"><td>Line</td><td>2</td></tr>
<tr id="line3"><td>Line</td><td>3</td></tr>
</table>
Now, in javascript (based on a radio input field) I want to remove (e.g.) #line3 by adding a visibility:collapse, something like:
document.getElementById("line3").style = "visibility:collapse";
The special thing about #line3 is that it has a border-top:
<style>
table {
border-collapse: collapse;
}
#line3 {
border-top:1px solid black;
}
</style>
The problem I have with that: When I "collapse" #line3 the border persists, eventhough the element "does not exist". I guess this should be due to the border-collapse in the table style "inheriting" a border element on the previous tr element? How can I fix that issue?
EDIT: I'd like to keep the javascript like that. Of course I could remove/readd the style element but there should be a different way to solve this?!
Of course I could remove/readd the style element
I think this means you don't want to mess with the border-top property when changing the row's visibility, correct?
In that case, it looks like your only option is to use display:none instead of visibility:collapse[1], which is unfortunate because then your table might have the wobbly effect that visibility:collapse was designed to prevent.
[1] https://drafts.csswg.org/css-tables-3/#visibility-collapse-track-rendering is not crystal clear, but looks like the spec prescribes the behavior you don't want. And chrome and firefox act a bit differently in the visibility:collapse case. https://jsfiddle.net/dgrogan/gLqo9s4w/2
let visible = 1;
toggle.onclick = function() {
line3.style.visibility = visible ? "collapse" : "visible";
//line3.style.display = visible ? "none" : "table-row";
visible = !visible;
}
table {
border-collapse: collapse;
}
td {
border: 1px solid lime;
}
#line3 {
border-top: 2px solid black;
}
<table>
<tr id="line1">
<td>Line</td>
<td>1</td>
</tr>
<tr id="line2">
<td>Line</td>
<td>2</td>
</tr>
<tr id="line3">
<td>Line</td>
<td>3</td>
</tr>
</table>
<br><br>
<button id=toggle>toggle</button>

Have you tried "display: none"?
document.getElementById("line3").style = "display: none";
Or maybe you could try setting the border-top to 0 which should hide it.
document.getElementById("line3").style = "visibility:collapse; border-top: 0";
.cssText
You can edit the whole inline [style] attribute by using .cssText:
document.getElementById("line3").style.cssText = "visibility:collapse; border-top:0px";
This allows you to set visibility and border properties (and more if you want) in one line.
Demo
document.getElementById("line3").style.cssText = "visibility:collapse; border-top:0px";
table {
border-collapse: collapse;
}
#line3 {
border-top: 1px solid black;
}
<table>
<tr id="line1">
<td>Line</td>
<td>1</td>
</tr>
<tr id="line2">
<td>Line</td>
<td>2</td>
</tr>
<tr id="line3">
<td>Line</td>
<td>3</td>
</tr>
</table>
You have several solutions to do this, with Jquery:
$('#line1').hide();
//OR
$('#line1').css('visibility','collapse');
//OR
$('#line1').css('display','none');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr id="line1"><td>Line</td><td>1</td></tr>
<tr id="line2"><td>Line</td><td>2</td></tr>
<tr id="line3"><td>Line</td><td>3</td></tr>
</table>
You can also use Javascript directly with the getElementById property:
document.getElementById("line1").style.display = "none";
Or
document.getElementById("line1").style.visibility = "collapse";
I have been struggling to create a html table(I also use bootstrap). To make it easier to understand what I want to achieve, see picture below.
https://s15.postimg.org/ulq2gxap7/Hiro_Table.jpg
Depending on how many elements(lets say cars), the user selects, I want to create a column for each car. I have an array with the id of the selected itmes.
For now I do like this:
For(selected){
//get data from my object with id
.....
$('table thead tr').append(html);
$('table tbody').append(htmlData);
}
Which outputs:
-----car1-------------car2--------------car3
----1911-------------Italian------------Red
----1923 ------------Italian------------Yellow
----1923 -----------Swedish------------Green
I want as the picture I link to.
You didn't supplied the full HTML and JS code but basically between each TR with three TDs you need to append tr with td that have collspan=3
for example:
table td {
border: 1px solid #CCC;
text-align: center;
}
<table>
<tr>
<td colspan="3">italian</td>
</tr>
<tr>
<td>Fiat</td>
<td>Ferarri</td>
<td>1992</td>
</tr>
<tr>
<td colspan="3">German</td>
</tr>
<tr>
<td>BMW</td>
<td>VW</td>
<td>Mercedes</td>
</tr>
</table>
I have a dynamic table that I made with javascript. Depending on different user events, some rows will be hidden, rearranged, ect. To be more specific, I'm using display:none; to do this. The issue is the rows always keep their original background color (imagine if all the rows were visible, then you could see the alternating colors). That would be fine if I had the entire table visible, but like I mentioned, sometimes certain rows will be hidden or appear at different positions. This often results in two or more rows of the same color being stacked on top of each other.
There is a similar post:
Alternate table row color even if row is removed
I tried as many of those solutions as I could. However my problem persists. Probably due to the following reasons:
I'm not removing the columns, I'm simply setting display:none;
I'm not working in a jquery environment, so I am limited to native javascript solutions
My code is:
tr:nth-child(even) {
background:gray;
}
tr:nth-child(odd) {
background:lightgray;
}
I have tried tr:nth-of-type(odd) and many similar variants. Is there anything else in CSS or native javascript I can try?
More on Visbility/Selection:
CSS:
tr:not(.selected) {
display: none;
}
JS:
my_circles.each(function(d,i) {
if (my_bool===true) {
d3.select(this).classed('selected',true);
tableRows.get(this).classed("selected", true);
}
});
I'm using d3.js, but I think I will omit the d3 tag, because this seems more of a css or js issue. This is a small snippet, mostly for context, but essentially we should be able to infer the visibility is toggled by a class assignment. If you are curious, it is whenever the user selects a circle on my adjacent scatter plot.
Unfortunately, there is no straight-forward CSS only solution for this problem. Primarily because the :not selector does not go together with nth-... selectors.
Your best bet would be to re-stripe your rows everytime via Javascript.
Stripe your rows as soon as your page is loaded. After that, whenever you change display on any row, you fire your stripe function again.
Here is a crude example:
var tab = document.getElementById("tab"),
btns = tab.getElementsByTagName("a"),
show = document.getElementById("show"),
rows
;
stripe(); // Stripe the rows in beginning
// The stripe function itself
function stripe() {
// select all rows which are not hidden
rows = tab.querySelectorAll('tr:not(.hidden)');
// add a class for every second such row
for(var x = 0; x < rows.length; x++) {
if (x % 2 == 0) { rows[x].classList.add('alt'); }
else { rows[x].classList.remove('alt'); }
}
}
// dummy buttons to hide each row in this demo
[].forEach.call(btns, function(elem) {
elem.addEventListener('click', hide);
});
// your actual code where you hide your rows
function hide(e) {
e.target.parentNode.parentNode.classList.add('hidden');
stripe(); // fire re-striping when hiding rows
}
// dummy button to show rows in this demo
show.addEventListener('click', function(e) {
rows = tab.querySelectorAll('tr.hidden');
[].forEach.call(rows, function(row) {
row.classList.remove('hidden');
});
stripe(); // fire re-striping when showing rows
});
table { width: 70%; border: 1px solid gray; border-collapse: collapse; }
td { border: 1px solid gray; padding: 4px; }
tr.hidden { display: none; }
#tab tr.alt { background-color: #ddd;}
<table id="tab"><tbody>
<tr><td>Row 1</td><td>Hide</td></tr>
<tr><td>Row 2</td><td>Hide</td></tr>
<tr><td>Row 3</td><td>Hide</td></tr>
<tr><td>Row 4</td><td>Hide</td></tr>
<tr><td>Row 5</td><td>Hide</td></tr>
</tbody></table><br />
<a id="show" href="#">Show All</a>

It is not a CSS or native JS solution but here is a d3 based solution. You could change classes of the rows every time the rows in your table change.
d3.selectAll("tr.selected").classed("grey",function(d,i){return i%2 == 0});
It adds the grey class to every second row and removes it from all the rest. Then you can color rows using css.
tr.grey {
background:gray;
}
tr:not(.grey) {
background:lightgray;
}
Here is a jsbin that shows this strategy in action.
this is not a perfect solution, but you can use gradient background in table to get desired result.
below is sample using gradient background in table.
tr:not(.selected) {
display: none;
}
table {
background-color: gray;
background-image: linear-gradient(transparent 50%, lightgray 50%);
background-size: 100% 36px;
}
<table width="500" cellpadding="0" cellspacing="0">
<tr class="selected">
<td>A</td>
<td>B</td>
</tr>
<tr class="selected">
<td>C</td>
<td>D</td>
</tr>
<tr>
<td>E</td>
<td>F</td>
</tr>
<tr class="selected">
<td>G</td>
<td>H</td>
</tr>
<tr>
<td>I</td>
<td>J</td>
</tr>
<tr>
<td>E</td>
<td>F</td>
</tr>
<tr class="selected">
<td>G</td>
<td>H</td>
</tr>
<tr class="selected">
<td>G</td>
<td>H</td>
</tr>
<tr class="selected">
<td>G</td>
<td>H</td>
</tr>
<tr>
<td>I</td>
<td>J</td>
</tr>
</table>
As you correctly pointed out, the reason that the css alternating stripes dont work is that your rows are remaining in place, and just being hidden using display:none.
The trick is to "group" the visible and hidden rows together so that we dont end up with un-event striping. Given that the order of your rows is not important, what we can do is move the hidden rows to either the top (using .insertBefore) or bottom (using .appendChild) of their containing parent. Something similar to this:
my_circles.each(function(d,i) {
if (my_bool===true) {
d3.select(this).classed('selected',true);
var row = tableRows.get(this);
row.parentNode.appendChild(row);
row.classed("selected", true);
}
});
I have an AngularJS module with a page that shows a table of topics and subtopics. Each topic is a tbody element with 2 rows: one representing the topic name, and one containing a nested table where the rows are the subtopics. Each topic has an expand / collapse button that controls the subtopics, i.e. ng-shows / hides the row where the subtopics table is:
<table>
<tbody ng-repeat="topic in topics">
<tr>
<td>{{topic.name}}</td>
<td class="toggle-subtopics" ng-click="toggleSubtopics(topic)">Expand / collapse</td>
</tr>
<tr class="test-height" ng-show="topic.expanded">
<td colspan=2>
<table>
<tr ng-repeat="subtopic in topic.subtopics">
<td>{{subtopic.name}}</td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
I'd like the subtopics row to appear / disappear with ng-animation, but the main problem is that no matter what I do, I can't seem to control the height of this row.
Fiddle
In order to control a td height you need to work on the line-height instead of height
Fiddle
Code Snippet:
.test-height {
line-height: 40px !important; /* This doesn't affect the height of the row */
}
Option 1:
Updated Code:
.table > tbody > tr >td {
line-height: 40px !important;
}
Updated Fiddle Option 1
Option 2:
If you do not want to mess with bootstrap global space you can create your own class and assign that to individual td
Updated Code:
.fixed-height {
line-height: 40px !important;
}
Updated Fiddle Option 2
Try This:
.test-height {
height: 3px;
overflow:hidden;
display:block;
}
I am trying to apply the following CSS to multiple divs under a given div ID.
.strikeout
{
background : blue;
}
I am using the following javascript code to change the color of the selected row in the grid,
$("#jqxGridInvoiceEntry").on("cellvaluechanged", function (event){
var rowindex = event.args.rowindex;
var checkboxState=event.args.value;
var rowTag=$("#row"+rowindex+"jqxGridInvoiceEntry div");
if(checkboxState==true)
{
rowTag.addClass("strikeout");
}
else
if(checkboxState==false)
{
rowTag.removeClass("strikeout");
}
});
See the screeshot below. When I select the checkbox in first row, its background color changes to blue. The problem is when I select the checkbox in second row, its background color changes blue but the previously selected row's background color disappears. The first row ID will be row0jqxGridInvoiceEntry and so on for subsequent rows.
I am using JQWidgets framework. The HTML code is,
<div style="float: left;" id="jqxGridInvoiceEntry"></div>
The only possibility, judging from the code you posted, is that the cellvaluechanged event also fires for the first row, perhaps because the checkbox in it is unchecked when you check the other checkbox in row 2.
This code:
else
if(checkboxState==false)
{
rowTag.removeClass("strikeout");
}
will remove the background color.
I think the way jquery implemented is little confusing. Here I am coming with different way of implementing the same result.
HTML
<table cellpadding="0" cellspacing="0" border="0" width="100%" id="MainTable">
<tr>
<td>First</td>
<td><input type='checkbox' /></td>
<td>Some INformation</td>

look to me like, your page is kind of reloaded when your callback is over.
if found this. they say you should use preventDefault() to forbid this behavior. hope it helps
