Say I had links with up/down arrows for moving a table row up or down in order. What would be the most straightforward way to move that row up or down one position (using jQuery)?
There doesn't seem to be any direct way to do this using jQuery's built in methods, and after selecting the row with jQuery, I haven't found a way to then move it. Also, in my case, making the rows draggable (which I have done with a plugin previously) isn't an option.
You could also do something pretty simple with the adjustable up/down..
given your links have a class of up or down you can wire this up in the click handler of the links. This is also under the assumption that the links are within each row of the grid.
$(document).ready(function(){
$(".up,.down").click(function(){
var row = $(this).parents("tr:first");
if ($(this).is(".up")) {
row.insertBefore(row.prev());
} else {
row.insertAfter(row.next());
}
});
});
HTML:
<table>
<tr>
<td>One</td>
<td>
Up
Down
</td>
</tr>
<tr>
<td>Two</td>
<td>
Up
Down
</td>
</tr>
<tr>
<td>Three</td>
<td>
Up
Down
</td>
</tr>
<tr>
<td>Four</td>
<td>
Up
Down
</td>
</tr>
<tr>
<td>Five</td>
<td>
Up
Down
</td>
</tr>
</table>

$(document).ready(function () {
$(".up,.down").click(function () {
var $element = this;
var row = $($element).parents("tr:first");
if($(this).is('.up')){
row.insertBefore(row.prev());
}
else{
row.insertAfter(row.next());
}
});

I have a question, I am trying to make some manipulation with html tables. I have two tables,
and when I hover first row from the first table, it should highlight both rows from both tables.
I have found a solution, in making this simple function:
<script type="text/javascript">
function matchrow(){
document.getElementById('row1').style.backgroundColor='#f5f5f5';
}
function unmatchrow(){
document.getElementById('row1').style.backgroundColor='white';
}
</script>
On the first table I have:
<tr onmouseover="matchrow()" onmouseout="dismatchrow()" >
on the second table I have:
<tr id="row1" >
So when I put mouseover the first row from the first table, the first row from the second table highlights.
My question is, how to make it for the every single row, especially if it will be dynamic table.
Hope I was clear.
I've implemented this with jQuery. It doesn't use obtrusive JS and doesn't require additional IDs for rows.
Also, CSS classes are more preferable than inline styles.
HTML:
<table id="t1">
<tr><td>......</td></tr>
<tr><td>......</td></tr>
</table>
<br/>
<table id="t2">
<tr><td>......</td></tr>
<tr><td>......</td></tr>
</table>
CSS:
tr.active > td
{
background-color:#f00;
}
JS:
$(function(){
$("#t1 tr").hover(
function(){
$(this).addClass('active');
$('#t2 tr:eq(' + $('#t1 tr').index($(this)) + ')').addClass('active');
},
function(){
$(this).removeClass('active');
$('#t2 tr:eq(' + $('#t1 tr').index($(this)) + ')').removeClass('active');
}
);
});
Here is live fiddle: http://jsfiddle.net/keaukraine/KBEhA/1/
You can use the div id as a parameter in the function
<tr onmouseover="matchrow('row1')" onmouseout="dismatchrow('row1')">
function matchrow(divid){
document.getElementById(divid).style.backgroundcolor='#F5F5F5';
}
function dismatchrow(divid){
document.getElementById(divid).style.backgroundcolor='white';
}
You can use jQuery for this.
Use the .eq() and .index() functions.
A way of doing it:
HTML:
<table border="1">
<tr>
<td>Row1</td>
</tr>
<tr>
<td>Row2</td>
</tr>
<tr>
<td>Row3</td>
</tr>
<tr>
<td>Row4</td>
</tr>
</table>
<table border="1">
<tr>
<td>Row1</td>
</tr>
<tr>
<td>Row2</td>
</tr>
<tr>
<td>Row3</td>
</tr>
</table>
JS:
$('table tr').hover(function()
{
var index = $(this).index();
$('table').each(function()
{
$(this).find('tr').eq(index).css('color', 'red');
});
});
A working example can be found here.
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
});

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');
}
I have a table like this:
<table class="thisTable">
<tr>
<td class="firstColumn">First</td>
<td>Apple</td>
<td>Ant</td>
</tr>
<tr>
<td class="firstColumn">Second</td>
<td>Banana</td>
<td>Bear</td>
</tr>
<tr>
<td class="firstColumn">Third</td>
<td>Citrus</td>
<td>Cat</td>
</tr>
</table>
What I wanted to do is to be able to click the link in td.firstColumn even if I click on the other cells in the same row. How do I do this in Dojo? Thanks a lot!
Give the rows a unique class name, then query the domNode and add connect's to them with a loop.
var that = this;
dojo.query('rowClass', this.domNode).forEach(function (node, index, arr) {
dojo.connect(node, "onclick", function (evt) {
that.handleEvent(evt);
});
});
I'm looking for some help on the Javascript angle of this problem. I have a table that goes like...
<table>
<tbody>
<tr> (Row 1)
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr> (Row 1a)
<td>
<select option>
</td>
</tr>
<tr> (Row 2)
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr> (Row 2a)
<td>
<select option>
</td>
</tr>
<tr>
<td colspan="3">
<p>This Says Something</p>
</td>
</tr>
<tr>
<td>
<select option>
</td>
</tr>
<tbody>
</table>
There are actually more like 20 rows and row a's but I didn't think I'd want to copy them all.
I basically need to add a container row (a single row) around every two rows (# and #a). Something like:
<tr> (Container Row 1)
<td>
+<tr> (Row 1)
+<tr> (Row 1a)
</td>
</tr>
It needs to cycle through the whole table. Somehow it has to retain the HTML data inside since all of the "a"s have options.
I hope this makes sense...
Any help would be greatly appreciated, as I'm at a loss. I'm novice at best at javascript and am struggling my way through the DOM and TOM methods.
Thank you so much in advance for any help or headway.
[EDIT] For clarification, the table is already constructed from a third party database, I am editing it after it's constructed. I guess this clarifies why it would have to be javascript to be done through the DOM.
Embed another table:
<tr> (Container Row 1)
<td>
<table>
<tr><td>(Row 1a)</td></tr>
<tr><td>(Row 1b)</td></tr>
</table>
</td>
</tr>
Or if you are wanting to do that via Javascript, you can give the parent <td> an id and set it's innerHTML.
<tr> (Container Row 1)
<td id='rowX'>
</td>
</tr>
document.getElementById('rowX').innertHTML = "<table><tr><td>(Row 1a)</td></tr><tr><td>(Row 1b)</td></tr></table>";
As mentioned in another answer you can't add tr elements directly in td like you are trying.
You would first create an inner table.
If you were using jQuery you would do something like this:
//setup some click actions just to prove that they remain attached even after moving
$('#outterTable tr').click(function(){
alert('You clicked on row: '+$(this).text());
});
//update the table (group each even row with the one after it)
$('#outterTable tr:even').each(function() {
var $tr1 = $(this),
$tr2 = $tr1.next('tr'),
$t = $('<table></table>');
$('<tr></tr>').append($t).insertBefore($tr1);
//click actions will remain attached
//if that is not required, than use $tr1.remove()
$t.append($tr1).append($tr2);
});
See this live jsFiddle example.
without jQuery it may look like that:
<script type="text/javascript">
<!--
function fx(table)
{
var tmp=document.createElement('table');
tmp.appendChild(document.createElement('tbody'))
while(table.rows.length)
{
if(table.rows.length%2==0)
{
var wrapper=tmp.lastChild.appendChild(document.createElement('tr'));
wrapper.appendChild(document.createElement('td'));
wrapper.getElementsByTagName('TD')[0].appendChild(document.createElement('table'));
wrapper.getElementsByTagName('TD')[0].lastChild.appendChild(document.createElement('tbody'));
}
wrapper.getElementsByTagName('TD')[0].lastChild.lastChild.appendChild(table.getElementsByTagName('TR')[0])
}
table.parentNode.replaceChild(tmp,table);
tmp.setAttribute('border',1);
}
window.onload=function(){fx(document.getElementsByTagName('table')[0]);}
//-->
</script>

But: why do you need this grouping?
If the only benefit is a visible grouping I would prefer to do this by setting the borders of the cells .
Give all cells a border and to the even a border-top:none / to the odd a border-bottom: none
I have a table structure:
<table style="width: 100%;">
<tr>
<td>
one
</td>
<td>Two</td>
<td>Three</td>
</tr>
<tr>
<td>
Four
</td>
<td>Five</td>
<td>Six</td>
</tr>
<tr>
<td>
Seven
</td>
<td>Eight</td>
<td>Nine</td>
</tr>
</table>
CSS:
.yy
{
background-color: red;
}
Now the problem is if I click on the <a> its corresponding <tr> element (<tr> that holds the <a>) background should be red, again if I click on the same <a> it should come back to normal.
How to identify the the <tr> on which the <a> is clicked.
EDIT:
I tried:
$(".yy").not($(this).parent().parent()).removeClass("yy");
$(this).parent().parent().toggleClass("yy");
it worked.
$('a').live('click', function(){
$(this).parent().parent() //this is how you select the <tr> that the <a> is in
//first .parent() gets the <td> second .parent() gets the <tr>
});
Let me know if you need more. There might be a better way but I'm not positive.
I think closest() should get what you are looking for.
$('a').click(function() {
var tr = $(this).closest('tr');
tr.toggleClass('yy');
});
This way you do not have to assume anything about how nested the anchor is in the containing tr.
