I'm facing a little problem with my code :
<style>
.btn_remove{
position:absolute;
right:-25px;
}
.test:hover > table{
background-color:#708ab3;
}
</style>
<a href="page/ABC" class="test" ng-mouseenter="showRemove = true" ng-mouseleave="showRemove = false">
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>mercedes class a</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Color: Red</td>
</tr>
</table>
</a>
So as you can see I have a table into a <a href>. When I pass my mouse over the table it calls the class .test:hover > table and also set the angular variable showRemove = true which will then show the absolute div on the right of the table.
My problem is when I mouse over the absolute div, it has the href from the parent (page/ABC).
If I try to write
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
then nothing is working because the first link isn't closed.
How could i manage to get :
Mouseover on table = background change + link (page/ABC) + show remove image on the right.
Mouseover on remove image = JS function to be called or whatever but do not be part of the parent link.
Mouseout of table or remove image = remove "remove image" and remove background change.
All this without using jquery. JS or angular, but i guess it's mostly div and css.
Solution:
<style>
.test{
position:absolute;
right:-25px;
visibility:hidden;
}
.wrapper:hover table{
background-color:#708ab3;
}
.wrapper:hover .test
{
visibility:visible;
}
</style>
<div class="wrapper">
<div class="test"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<a href="table link">
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>Mercedes Class A</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Red</td>
</tr>
</table>
</a>
</div>

Glad to hear you got it working.
for reference you can add javascript:; to the href of an anchor to make it not do anything.
You can select a child element on hover using:
.parent:hover .child
{
the hover styles for the child
}
here is the fiddle for anyone else who needs to select a child element on hover jsfiddle.net/jE7J6

I want to show multiple tables in a web page with header and the image displayed inside the table cell.
To achieve that i have created one table and used <div> tag to assign the width and height of the <td>.
Please find the code below
<table width="100%" height="100%"><tr><td>
<div style="position:absolute;border: 1px solid black;width:200px;height:200px";>
<section>
<header style="background: gray;width:198.5px;text-align: center">Header1</header>
</section>
<img style="display:block;" width="100%" height="100%" src="http://hearstcommerce.ca/customcontent/members/premium/sample.jpg" alt="tableDemo2" />
</div></td>
<td>
<div style="position:absolute;border: 1px solid black;width:200px;height:200px";>
<section>
<header style="background: gray;width:198.5px;text-align: center">Header2</header>
</section><br><br>
<br><br> <img style="display:block;" width="100%" height="100%" src="http://hearstcommerce.ca/customcontent/members/premium/sample.jpg" alt="" />
</div></td>
</tr></table>
I want to display that image in the whole cell of <td>. The header section should be displayed follwed by the image in the whole space. Please suggest what code do i need to add to make it work. Currently i could not able to set properly the image inside the border of the <td>. Or is there any good approach to achieve this.
jsfiddle:http://jsfiddle.net/4S6gR/103/
I want to achieve this using html/css.
After looking at you fiddle I think you meant you want the image to cover rest of the area in the cell other than header.
If so:
Check this Fiddle
Added a new div to cover the div, gave a height to the header 18px, as was rendered by browser and then gave height of 182px to the div containing image.
I want to display that image in the whole cell of td.
Forget img tags, there is a way easier way.
<td style="background-image:url('asd.jpg');">
you should use th instead of formatting inside td with div to create header, also you'll need to remove the height width from header
.mytable{
width:100%;
height:100%;
}
.mytable header{
background: gray;
text-align: center;
}
.mytable img, header{
width:200px;
}
.mytable td img{
display:block;
}
<table class="mytable">
<tr>
<th>
<section>
<header>Header1</header>
</section>
</th>
<th>
<section>
<header>Header2</header>
</section>
</th>
</tr>
<tr>
<td>
<img src="http://hearstcommerce.ca/customcontent/members/premium/sample.jpg" alt="" />

</td>
</tr>

I have a table with each row representing a song.
When a song is clicked, the parent td should be highlighted a light blue color with the .active class and if any song was highlighted previously the parent td's .active class should be removed.
This part works fine and is represented with this jquery:
$(".songs").click(function(){
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
I also want to have a next button and a previous button. This where I am having issues. When the next button is clicked, the next song on the list should be highlighted and the previously highlighted song should be unhighlighted (I am using the class .active to do the highlighting and unhighlighting). This part is not working:
$('#next_button').click(function(){
var current = $('td.active');
$('.songs').parents('td').removeClass('active');
current.nextAll('td:first').addClass('active');
});
Here is the jsfiddle link:

The trick is to get the row index of the current song, add 1, and then do a modulo with number of rows that way if the current row+1 overflows the number of rows, it will start from the beginning:
$().ready(function() {
$(".songs").click(function(){
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
$('#next_button').click(function(){
//here .parent() will get the current <tr>
//.parent().index() will get the index of the current <tr>
var currentID = $('td.active').parent().index();
//here .parent() will get the <tr>
//.parent().parent() will get the <tbody>
//.parent().parent().children() will get all the rows
//.parent().parent().children().length will get the row count
var nextID=(currentID+1)%($('td.active').parent().parent().children().length)
$('.songs').parents('td').removeClass('active');
$('td').eq(nextID).addClass('active');
});
});
.active{
background-color: #D9FAFA;
}
table{
text-align: center;
height: 100px;
width: 200px;

#table_head{

Something like this? http://jsfiddle.net/y5ntap04/3/
You needed to go up the DOM and then where all the siblings are, you can go to the next() one.
Plus added a previous button for you.
$().ready(function () {
$(".songs").click(function () {
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
$('#next_button').click(function () {
$('.songs').parents('td.active').removeClass('active').closest('tr').next().find('td').addClass('active');
});
$('#previous_button').click(function () {
$('.songs').parents('td.active').removeClass('active').closest('tr').prev().find('td').addClass('active');
});
});
in your code you have each td in its own tr meaning there is no next td to go to.
you should adjust your jquery to focus on the rows, as in this fiddle (shown below)
$().ready(function() {
$(".songs").click(function(){
$('.songs').parents('tr').removeClass('active');
$(this).parents('tr').addClass('active');
});
$('#next_button').click(function(){
var current = $('tr.active');
$('.songs').parents('tr').removeClass('active');
current.next('tr').addClass('active');
});
});
You'll also notice I'm using .next() which will just grab the next element or the next element which matches the argument (in this case tr) - no need to get all then restrict to just the first.
All this will make your fiddle behave as expected, however, if you want to target the td's within each of the tr's you'll have to add .find('td') to get the td out of the retrieved tr, like this. Here the only line that is changed is the one that adds the class on click of next, which is now: current.parent().next('tr').find('td').addClass('active');
Refactoring out $('.songs').parents('tr').removeClass('active'); into it's own function would also clear your code a bit and make it easier to follow, a good habit! (also +1 for using a variable to store a returned JQuery DOM object - var current = $('tr.active'); - another good habit for code clarity and efficiency, especially when you are deraling with more complicated DOM structures and functions)
I'm new to Javascript and I'm working on a project. Thanks to help from a online help website, I'm able to show/hide my table successfully.
When I click the h3 element, it opens up and append the anchor (in this situation, #1, #2, #3) to the URL.
I want to use this anchor element to open up the specific table from an external link from another web page. (e.g. at Home Page, I clicked on this testing.html#1, I want it automatically open the 1st table when I reach the page)
Thank you very much!

Note this only work if you are loading from a html page in the same domain.
JQuery's .load function is very versatile. To load the first table from testing.html, we can do:
$('#tableContainer').load('testing.html table:eq(0)');
2nd table:
$('#tableContainer').load('testing.html table:eq(1)');
and so on.
demo
Note that the 3 tables in the demo are loaded from here
If the URL ends with #1, and you need showonlyone('newboxes1') automatically executed:
if (window.location.hash.substr(1) == '1') {
showonlyone('newboxes1');
}
I have the following site:
http://www.pachamber.org/www/advocacy/index.php
When a user clicks the 'General Commerce' href tag towards the bottom, it should slide out the hidden contents. All of the other tags work correctly except this one.
The function behaves unexpectedly only in IE. It looks to be fine in Chrome and FF. When debugging the function, it seems not not grab the height attribute from the div:
<div id="general" style="display: none; height: 30px; overflow: hidden">
The height attribute is showing as 1px on this line:
this.height = parseInt(this.obj.style.height);
Here is the snippit of HTML and the function call:
<table width="100%" border="0" cellspacing="0" cellpadding="6">
<tr>
<td colspan="2" style="width: 100%;">
<div class="subheading2" style="border-bottom: thin solid gray; cursor: pointer; color: #000099" onClick="doSlideOut('general');"><a name="general"></a>General Commerce</div>
</td>
</tr>
</table>
<div id="general" style="display: none; height: 30px; overflow: hidden">
<table width="100%" border="0" cellspacing="0" cellpadding="6">
<tr>
<td width="53%">
• <a href="gc/testimony/index.php" >Testimony & Comments</a>
</td>
<td width="47%"> </td>
</tr>
</table>
</div>
Any ideas what I am missing?
Thanks.
Beware of id and name attribute when using getElementById in Internet Explorer describes the stupid behaviour of IE which causes the problem of yours.
If there are two elements with the same value for id and name (in your case its the div with id general-commerce and the link General Commerce) IE will grab one of both of them when using getElementById.
The solution would be to change either the name-attribute of the link or the id of the div-container.
One thing I saw was and error in your script.
Errors like these break JS from running properly.
Check out one of my websites to see how to do this with jQuery (look at the links under "Our Curriculum").
$('.lgroup').on('click', function () {
if ($(this).hasClass('directLink')) {
return true
} else {
$('.links').slideUp();
$('.lgroup').removeClass('lactive');
if ($(this).next().css('display') == 'block') {
$(this).next().slideUp()
} else {
$(this).addClass('lactive').next().slideDown()
}
}
});
I'm having a problem while trying to dynamically change a table cell's styling class using JavaScript.
The following issue happens on FF, I opened the page on other browsers too and it worked fine.
I have a html page that contains a 4x4 table. I would like when I click on a cell, to zoom it in and when I click on it again to zoom it out. I defined 2 CSS classes, one for the normal size cell and one for the zoomed cell. I am using JS to change the CSS class when a cell is clicked.
The issue on FF is that when changing from zoomClass to normalClass all the cells to the right of the clicked cell are shifted to the right...
I can't find a solution or a workaround for this problem, if somebody has any ideas please post them here.
Next, I will attach the html, css and js files.
Thanks :)
util.js
function zoom(id) {
if (document.getElementById(id).className == "zoomClass") {
document.getElementById(id).className = "normalClass";
} else {
document.getElementById(id).className="zoomClass";
}
}

Unfortunately "position" doesn't work on table cells. You could try putting a div inside the table cell and positioning that.
Edit: Something like this should do the trick:
td.normalClass div {
display: none;
}
td.zoomClass div {
display: block;
position: absolute;
width: 320px;
height: 240px;
}
Make sure the div is the first thing in the td and it'll be positioned at the td's top left corner. You might need to play with relative positioning on the td if you need to change the top and left values further.
This is how tables work. I possible I would try and do the same thing using divs and then you should be able to deal with the problem using position:absolute so the expanded div will overlay the others. This could work the same for a table cell.
A few comments on your code, if I may. I would keep the layout in the CSS file and not in the HTML, so I'd remove all of those align="right" and valign="top". Also, you can reference the cells in your table much more efficiently. Then you won't have to set the class for each cell.
#main_table td{
padding:0;
font-size:4px;
color:#3333FF;
}
I would also keep all of the behaviour of the page in a separate script file (Javascript). So no more onclick="zoom(x)" at every cell. You can use event binding to do that.
Also, if you use event binding, you can just "read" the id of the clicked cell, so you don't have to pass that value in statically in the call of the zoom function.
Lastly: I can highly recommend using jQuery to do this kind of DOM manipulation as it's a lot easier, the code is shorter and more readable and your scripts work across browsers pretty much out of the box.
I don't have a solution for this specific problem but using jQuery it's quite easy to insert a new DOM element, a div for instance, with the content of the clicked cell, float over the table and simulate the zoom effect. That div would be be absolutely positionable and can be styled a lot better than the cell the user clicked on.
