This change from mootools drives me crazy.
HTML
<tr class="teamicon">
<td style="text-align: center;" width="100%" valign="middle">
//Blahblah
</td>
</tr>
<tr class="teamval">
<td valign="middle" width="100%">
//Blahblah
</td>
</tr>
What I want to achieve. When with class "teamicon" is clicked I want to show/hide tr with class teamval with animation. However, I can't make it animate properly. Looks like inside "teamval" must be animated first (or am I wrong?).
My try:
jQuery(document).ready(function(){
$('.teamval').slideUp(400);
$('.teamicon').click(function(){
if ($(this).next('tr').is(":hidden"))
{
$(this).next('tr.teamval').$('td').slideDown(400, function(){
$(this).next('tr.teamval').slideDown(400);
});
}
else
{
$(this).next('tr.teamval').$('td').slideUp(400, function(){
$(this).next('tr.teamval').slideUp(400);
});
}
});
});
OFC. This is wrong ("$(this).next('tr.teamval').$('td')" returns error in firebug). How can I achieve this?
I can't swap to div though.
You could do one of:
$(this).next('tr.teamval').slideDown(...) // whole tr
$(this).next('tr.teamval').find('td').slideDown(...) // td descendant
The error is because you are trying to access a $ property on the jQuery element set, which doesn't exist. Instead we can use find, which searches for matching descendants of elements in the current set.
EDIT:
Okay, I think you want:
if ($(this).next('tr').is(":hidden"))
{
var nextTeamval = $(this).next('tr.teamval');
nextTeamval.find('td').slideDown(400, function(){
nextTeamval.slideDown(400);
});
}
The only potential problem is if teamval contains a td within a td (nested table). You can try this jsFiddle demo.

If I do the following is fine:
<div id="results">
<p>Hello<br>there</p>
</div>
$($("#results p").children('br').get(0).nextSibling).remove();
I get: hello
But if I do:
<th class="infobox">Head</th>
<td>Hello<br>there</td>
var newLineRemove = $(".infobox td").children('br').get(0).nextSibling();
$wikiDOM.find(newLineRemove).remove();
Gives me
Uncaught TypeError: Cannot read property 'nextSibling' of undefined
That is because .get(...) returns a DOM element not a jQuery object.
In the first example you're using $(...) to convert that DOM element to a jQuery object but you're not doing that in the second example.
This will convert the DOM element to a jQuery element and get rid of the error
var newLineRemove = $($(".infobox td").children('br').get(0).nextSibling);
But it won't do what you want it to do because as #Forty3 said "the <td> isn't inside the ..infobox"
This seems to work but I've probably made things more complicated then they have to be:
$(function(){
var td = $(".infobox").next();
if(td.find("br").length){
$(td.contents().get().reverse()).each(function(){
$(this).remove();
if(this.tagName == "BR"){
return false;
}
});
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<th class="infobox"></th>
<td>Hello<br>there</td>
</table>
I've simplest solution for this, try this one:
$('td').each(function() {
$(this).html($(this).html().split('<br>')[0]);
});
li {
margin-bottom: 10px;
}
#usp-custom-3 {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<table>
<tr>
<th class="infobox"></th>
</tr>
<tr>
<td>Hell
<br>there</td>
</tr>
<tr>
<td>Hello
<br>there<br>there</td>
</tr>
</table>
Your code doesn't work because the ".infobox td" selector is looking for a td element inside an .infobox element, but in your HTML the td immediately follows the .infobox.
If you want something that is very similar to your existing JS but working with that HTML (noting that td and th elements need to be inside a tr in a table) you can do this:
$($(".infobox").next().children("br")[0].nextSibling).remove()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
<tr>
<th class="infobox"></th>
<td>Hello<br>there</td>
</tr>
</table>
That is, use .next() to get the element following the .infobox, get that element's child br elements, take the first one's .nextSibling, then wrap it in a jQuery object so that you can call .remove().
EDIT: Note that if there were multiple rows with similar elements the above code would only do the removal on the first one. If it were my code I would probably select all of the relevant elements and then update their HTML something more like this:
$(".infobox").next("td").html(function(i, h) { return h.split('<br>')[0] })
I am using jQuery.
I want to select a cell from a table.
So I tried the following codes.
// First line works fine for me. I can get a list of columns at the correct target row.
var targetColumns = $(elemClicked).closest("tr").find("td");
// I want to get the cell with the class named "draftstatus". This line has problem. I cannot get what I want.
var targetCell = columnsAtTargetRow.$(".draftstatus");
The targetColumns inspected from browser looks like the following:
The 5th td above is my target cell.
I also try to use find() function. It won't work either because find() will start from next children level.
columnsAtTargetRow.find(".draftstatus"); // this does not work.
What functions should I used to get that cell within that "list of td".
Thanks in advance.
You just need to figure out which selectors to use.
var targetColumns = $(elemClicked).closest("tr").find("td");
this goes up the DOM to the "tr" and selects the tds. If the elemClicked is inside a td you can select the tds with closest("td"), and then use siblings(".draftstatus");
If the elemClicked is a td, then you can just use siblings(".draftstatus");
Here is some example code to help demonstrate some selectors. Hope this helps some and not confused you more.
$(function(){
//reference all cells with myclass class using filter
$("#table1 tbody td").filter(".myclass").addClass("red");
// click events for all tds reference the .target class cell using siblings
$("#table1 tbody td").on("click",function(e){
$(this).siblings(".target").toggleClass("red");
});
//items inside a table cell click event
$("#table1 tbody td a").on("click",function(e){
//toggle bold class
$(this).closest("td").siblings(".target").toggleClass("bold");
//prevent event from bubbling up
e.stopPropagation();
});
})
.red {
background-color:red;
}
.bold { font-weight:bold; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table border="1" id="table1">
<tbody>
<tr>
<td>foo</td>
<td>bar</td>
<td class="myclass target">value2</td>
<td>Two link</td>
</tr>
<tr>
<td>foo</td>
<td>bar</td>
<td class="myclass target">value2</td>
<td>Two link</td>
</tr>
</tbody>
</table>
This is incorrect:
columnsAtTargetRow.$(".myclass");
This should be:
columnsAtTargetRow.find(".myclass");
I have a table structure as follows;
<tr>
<td><div class="icon-chevron-right"></div></td>
<td><div>List 1</div></td>
</tr>
<tr>
<td><div class="icon-chevron-right"></div></td>
<td><div>List 2</div></td>
</tr>
Now on click of the icon image (chevron), I want the details row to be displayed immediately below the clicked row (It should be a tr containing child table). This should be inserted/appended dynamically on click of any of the list row.
How do I do this using jQuery? Any examples for reference would be really helpful..
the following example creates a new tr (if does not exists) containing table element under the tr where the clicked icon exists.
function createChildTable(string)
{
return $('<table>').append(
$('<tr>').append(
$('<td>').append(string)
)
);
}
$('.icon-chevron-right').click(function() {
var details = $(this).closest('tr').next('tr.details');
if (details.length) details.show();
else {
// first time clicked
details = $('<tr>').append( createChildTable('child table details') ).addClass('details');
$(this).closest('tr').after(details);
}
});

I'd say there are two main ways to do this, and you'll have to figure out which one is best for you; it depends.
What you're talking about is ADDING a row into the DOM. This is fine in some cases, it depends on what this collapsed row is used for. If you want to be able to remove the collapsed row and add it again, it could make your life difficult if you have to reconstruct all the inner HTML via JavaScript every time.
var collapseHTML = '<tr class="collapse"><td colspan="2">This is my new row</td></tr>';
$('.icon-chevron-right').click(function() {
$('.collapse').remove(); // Deletes all rows that has class "collapse"
collapseHTML.insertAfter( $(this).closest('tr') ); // Inserts what's stored in collapseHTML after "this closest tr"
});
Then, as someone else said, you can solve this by adding those rows from the get go like so:
<tr>
<td><div class="icon-chevron-right"></div></td>
<td><div>List 1</div></td>
</tr>
<tr class="collapse">
<td colspan="2">This is my new row</td>
</tr>
Then, your css should loook something like this:
.collapse {
display: none;
}
.collapse.active {
display: block;
}
This means that when you add the active class to the collapse row, it goes from display: none; to display: block;. This you do via JavaScript/jQuery:
$('.icon-chevron-right').click(function() {
$('.collapse.active').removeClass('active'); // Removes active from all active collapsed rows
$(this).closest('tr').next().addClass('active'); // adds active class to "this closest tr's next element" (which is the collapse row)
});
Hope this helps!
So here's my problem, I'm new to jQuery. What I am trying to do here is check for user to click on a certain table cell/row and it would then display a div named popup of an index the same as the table cell votes. Without having to make separate functions of all the rows in my table.
Using some numerical value will display all the dialogs from a click of the cell of the same value the first time and from the second time only the correct one.
I bet there's some other way to do it and maybe there's just a stupid error.
Using the index value in the click and dialog function won't work.
I am open to suggestions on improvement also.
The scripts:
<script type='text/javascript'>
$(document).ready( function() {
$('.votes').each(function(index) {
$('.votes:eq(index)').click(function() {
$('.popup:eq(index)').dialog();
});
});
});
</script>
HTML for the table part, only a snippet
<td class='votes'>5</td>
<td class='votes'>15</td>
<td class='votes'>25</td>
HTML for the div part, only a snippet of the div:
<div class='popup'>
<ul>
<li>John Johnsson</li>
<li>John Doe</li>
</ul>
</div>
<div class='popup'>
<ul>
<li>Matt Theman</li>
<li>Peter Watley</li>
</ul>
</div>
jsFiddle Demo
You don't have to iterate using each for .click, that will happen internally. You can use .index() to get the index of the element clicked with reference to its parent.
$('.votes').click(function() {
$('.popup').eq($(this).index()).dialog();
});
Initially, the main problem is that you are not using string concatenation to apply the index to the selector (demo):
$('.votes:eq(index)')
// the Sizzle selector engine doesn't know what the string "index" is.
instead of
$('.votes:eq(' + index + ')')
// using concatenation calls the .toString() method of index to apply "0" (or "1", "2", etc.)
// so that the parsed string becomes '.votes:eq(0)' which the Sizzle selector engine understands
Once the Sizzle selector engine understands which elements to target (demo), the second problem is how jQueryUI changes the DOM with the .dialog method.
Inital markup:
<table>
<tbody>
<tr>
<td class="votes">5</td>
<td class="votes">15</td>
<td class="votes">25</td>
</tr>
</tbody>
</table>
<div class="popup">
<ul>
<li>John Johnsson</li>
<li>John Doe</li>
</ul>
</div>
<div class="popup">
<ul>
<li>Matt Theman</li>
<li>Peter Watley</li>
</ul>
</div>
Once the first click event is handled, one of the div.popup elements is transformed into a jQueryUI Dialog and is appended to the body, removing it from its initial position, like so:
<table>
<tbody>
<tr>
<td class="votes">5</td>
<td class="votes">15</td>
<td class="votes">25</td>
</tr>
</tbody>
</table>
<div class="popup">
<ul>
<li>Matt Theman</li>
<li>Peter Watley</li>
</ul>
</div>
<div class="ui-dialog ui-widget ..."> ... </div>
So your initial indexes no longer apply. Fortunately, there are several solutions to both problems (a few of which I've listed below).
Solutions to Problem 1:
Use string concatenation as described above.
Use the .eq method instead, which will accept the index variable as-is
Use a delegate handler instead and grab the index from within the handler:
Example of 2:
$('.votes').eq(index);
Example of 3:
$('table').on('click', '.votes', function (e) {
var vote = $(this),
index = vote.parent().index(vote);
});
Solutions to Problem 2:
Create all of the dialogs initially and open them as needed.
Create the dialogs using a deep clone of the div element. (Not recommended)
Remove the td element to match the removed and re-appended div element. (Not recommended)
Example of 1:
var popups = [];
$('.popup').each(function (i, elem) {
var popup = $(elem).data('index', i).dialog({
"autoOpen": false
});
popups.push(popup)
});
$('table').on('click', '.votes', function (e) {
var vote = $(this),
index = vote.index();
popups[index].dialog('open');
});
I'm sure there are other solutions as well, but these are the ones I thought of of the top of my head.
Functional demo: http://jsfiddle.net/2ChvX/2/
UPDATE:
With your chosen table structure, you're actually looking for the index of the parent tr element as that is what corresponds with the div.popup element. To get the index of the parent tr element, change the line that gets the index from:
index = vote.index();
to:
index = vote.parent().index();

FWIW, here's an example using the jQueryUI dialog (which I presume you are using?) and javascript sectionRowIndex and cellIndex.
Reusable code allowing you to identify the cell the user clicked in and perform appropriate action.

<td class='votes'>25</td>

<td class='label'>Voters</td>
<td class='voters'>5,000</td>
<td class='voters'>15,000</td>
<td class='voters'>25,000</td>

$('#myTable tr td').click(function() {
myTr = $(this).closest('td').parent()[0].sectionRowIndex;
myCell = this.cellIndex;
myState = $('#myTable').find('tr:eq(0)').find('th:eq(' +myCell+ ')').html();
myVoters = $('#myTable').find('tr:eq(' +myTr+ ')').find('td:eq(' +myCell+ ')').html();

//California
$('#msg').html('There are ' +myVoters+ ' voters in ' +myState);

}else if(myTr==1 && myCell==1){
$('#msg').html('There were ' +myVoters+ ' votes made in ' +myState);

I have a dynamically loaded table with the following tr's:
<tr>
<td><span class="active">Task Name</span><br /><span class="icons_small">U</span><span class="contact_name tiny">Contact Name</span><span class="user_number tiny">(111111)</span><span class="icons_small" style="visibility:hidden;">!</span></td>
<td><span class="date_assigned">13/12/2012</span><br /> <div id="progressbar"></div></td>
<td class="icons_small"><span class="flag_task">f</span></td>
<td class="icons_small"><span class="set_reminder">A</span></td>
<td><span class="warning tiny" style="visibility:hidden;">Delete</span></td>
</tr>
Im trying to set the td with the spanclass "flag_task" (3rd td down) to toggleclass an additonal class, but only on the selected td with the spanclass "flag_task, not all instances of that class. This is what im currently using:
<script>
$(document).ajaxSuccess(function () {
$(".flag_task").click(function () {
$(".flag_task").toggleClass("warning");
});
});
</script>
Could someone please clarify how to effect only the selected instance.
Thanks,
Mark
In this section of the code, you're saying "grab all elements with a class of flag_task" instead of just "grab the clicked element."
$(".flag_task").click(function () {
$(".flag_task").toggleClass("warning");
});
So, to fix this issue, you just have to select the element that was clicked on.
This line:
$(".flag_task").toggleClass("warning");
Can be changed to:
$(this).toggleClass("warning");
