geekisthenewsexy · November 15, 2010

hi guys. as stated in my question above, i want to be able to highlight a table row when i click on it and unhighlight when i click on another row. i'm totally new to javascript and jquery so i don't know where to begin. i've used php also on this one to display the records in the table. hope you guys can help. just tell me if something is lacking in the code i've posted or if i need to post javascript. here's the html&php code..

<div id="tableheader">		
        	<div class="search">
                <select id="columns" onchange="sorter.search('query')"></select>

You can try onFocus and onBlur events.

eg:

Try it for yourself

geekisthenewsexy · November 15, 2010

thanks for the response TrueColors.

but uhm, i'm not sure where i will put this code.. i kind of queried the records into <td> like this

echo "<td>".implode('<td/>',$OutLine);

.. :-\

TrueColors · November 15, 2010

Sorry about the wait. I got a solution.

Example CSS:

    <style>
	.highlighted { background:black; color: white; }
	tr { cursor: pointer; }
</style>

Example JS:

	<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
	function myfunction (myTD)
	{
   			$(".highlighted").removeClass("highlighted");
    		$(myTD).addClass("highlighted");
	}
</script>

Example HTML:

	<table style="border:2px solid blue;" cellspacing="0">
    	<tr onclick="myfunction(this)">
        	<td>TD Box 1</td>
            <td>TD Box 2</td>
        </tr>
    	<tr onclick="myfunction(this)">
        	<td>TD Box 1</td>
            <td>TD Box 2</td>
        </tr>
    </table>

This is set so that when you click a row (TR) it'll add the class .highlighted which means the background will be black, text will be white. When clicking the other row (TR) - (Two in this example) it'll remove the class from the previous row (TR) and add it on the one you just clicked.

If you want it for TD, just remove the onclick from the TR's and place them in the TD's.

There is an easier method that doesn't require onclicks if you'd prefer that but I'd need some time alone to code it first

Hope this is what you're looking for.

TrueColors · November 15, 2010

To do the same as the above. Remove the onclicks, and use this JS instead.

    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script type="text/javascript">
        $(function() {
            $('tr').click(function() {
                   $('.highlighted').removeClass("highlighted");
                $(this).addClass("highlighted");
            });
        });
    </script>

To do it with TD's instead of TR's just change 'tr' to 'td'

geekisthenewsexy · November 17, 2010

hey, thanks!

okay i'll try it out.

geekisthenewsexy · November 20, 2010

hi, sorry for the delay.

i tried your code but unfortunately it doesn't seem to work with mine. or maybe i just don't know how to?

so i figured posting the entire jscript here..

see the comment?i think that's the part where the table is highlighted on mouseover. i tried inserting your code there but then, the highlight on mouseover didn't work anymore..maybe you know what to do? :-\

logicslab · November 23, 2010

Hi Geek,

I think to give one Highlight to a Row when mouse is over is simple .... You can Study following code, and not make things complex it's not much

complex ....

<html>
<head>
<style type="text/css">
<!--
#mytable {
  border-collapse: collapse;
  width: 300px;
}
#mytable th,
#mytable td
{
  border: 1px solid #000;
  padding: 3px;
}
#mytable tr.highlight {
  background-color: #eee;
}
//-->
</style>
<script type="text/javascript" src="jquery-1.4.4.js"></script>
<script type="text/javascript">
// var oldHistLength = history.length;
// setInterval ( "checkHistory()", 100 );
  
$(
function()
{
  $("#mytable tr").hover(
   function()
   {
    $(this).addClass("highlight");
   },
   function()
   {
    $(this).removeClass("highlight");
   }
  )
}
);




</script>
</head>

<body >

<table id="mytable">
<tr>
  <th>Foo</th>
  <td>Lorem</td>
  <td>Ipsum</td>
</tr>
<tr>
  <th>Bar</th>
  <td>Dolor</td>
  <td>Sit</td>
</tr>
<tr>
  <th>Baz</th>
  <td>Amet</td>
  <td>Consectetuer</td>
</tr>
</table>
</body>

Don't Worry abt PHP , it has no hand in highlighting !!! .... be happy coding

Bye Anes

hi there, sorry for the delay. been busy again with work.

thanks for the response logicslab.

but highlight on mouse over isn't exactly the problem..it's highlighting a row when it's clicked.

i've posted the javascript because i don't know what part of the script to modify,or where to put a highlight on click script there..here,let me show you the image of the table..

as you can see, the first row's been highlighted on mouse over. and in the last column on the right, are image button i've placed for adding,deleting,etc..

now my goal is, when i click on one of these buttons, say the one with the "plus" sign on the last row, that row should automatically be highlighted and depending on which row i click. of course, the highlight on mouse over should still remain.. i hope that's clear.. :-\
