JavaScript - Function Fadeout

Hi guys,

Im trying to get the hover to fade in the 'hover.png' image and to fade out when leaving the 'hovering' item.

The code I am using is the following

Code:

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js' type='text/javascript'></script>
<script type="text/javascript">

function mainmenu(){
	$("#neon li.root").hover(function(){
			$(this).fadeOut('500');
			},function(){	
		$(this).fadeIn('500');
			});	
	}

$(document).ready(function () {		
mainmenu();		
});
</script>

<style type="text/css">


 /* remove the margin and bullets, set the padding and margin for this demo only*/
.neon {margin:50px auto 200px auto; padding:25px 0 100px 15px; list-style:none; background:#000; width:720px;}

 /* display the list items inline with a right margin to space the buttons. Use this to pre-load the hover image */
.neon li {display:inline; float:left; background:url(hover.png);}

/* style the links and place the background image to start from left edge */
.neon li a {display:block; height:32px; float:left; background:url(menu.png); text-decoration:none; font-size:10px; font-family:arial, sans-serif; letter-spacing:1px; line-height:36px;}

/* style the b element to posiition it to the right by 20 pixels and even out the text with 20 pixel right padding */
.neon li a b {margin:0 0 0 40px; display:inline; float:left; height:32px; background:url(menu.png) right top; padding:0 40px 0 0; color:#fff;}

/* style the link hover and the link hover b to replace the background image - border:0 needed for IE6 to work */
.neon li a:hover, .neon li a:hover b {border:0; background-image:url(hover.png); cursor:pointer; color:#000;}

.neon li a.current, .neon li a.current b, .neon li a.current:hover , .neon li a.current:hover b {background-image:url(hover.png); color:#000; cursor:default;}

</style>

  <ul id="neon" class="neon">
    <li class="root"><a href="#nogo"><b>MENU ITEM1</b></a></li>
    <li class="root"><a href="#nogo"><b>MENU ITEM2</b></a></li>
    <li class="root"><a href="#nogo"><b>MENU ITEM3</b></a></li>
    <li class="root"><a href="#nogo" class="current"><b>MENU ITEM4</b></a></li>
    <li class="root"><a href="#nogo"><b>MENU ITEM5</b></a></li>
  </ul>

Any help would be appreciated!

Thanks!

Hi Guys,

I'm using jcarousellite to show my newsitems in a vertical carousel.
http://www.gmarwaha.com/jquery/jcarousellite/

The carousel itself works perfectly, now I'm trying to add that before the news scrolls upwards the top news-item fades-out first.

Now it is fading out the complete list and I simply can't seem to figure out how to 'talk' to the 'active/top' <li> in the list.


Can someone give me a hint?

Thanks in advance,
Marcel


-- Code Below --

Code:

$(function() {
	$(".widgetCarousel").jCarouselLite({
		circular: true,
		vertical: true,
		visible: 3,
		scroll: 1,
		start: 1,
		auto: 500,
		speed: 1000,
		beforeStart: function(a) {
			$(a).parent().fadeTo(100, 0);
    		},
		afterEnd: function(a) {
			$(a).parent().fadeTo(100, 1);
		}
    	});

});

<div class="widgetCarousel">
	<ul>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>	
	</ul>	
</div>

How can I add fadeIn and fadeOut with a duration that I can set/adjust to this javascript?
The site is using Zencart and the the Image Hover effect comes from the Image Handler 2 Add-on.

Thank you in advance for your help. Your time and attention in helping me with this is greatly appreciated.

Here is a link to the site residing on a subdomain I use to build sites on http://test3.fullspecweb.com

I read the "Read Before Posting" and it said to only post the code you are having trouble with, but I have no idea which section that would be so I apologize for being such a noob

Here is the script from the jscript_imagehover.js file...

var padding=10; // padding must by larger than specified div padding in stylessheet

// Global variables for sizes of hoverimg
// Defined in "showtrail()", used in "followmouse()"

Is it possible to have a form's textarea background image fadeout to an alternate bg image, when that textarea is selected (by clicking the textarea or tabbing to it)? I've never seen this done before, but I'd really like to do it..

I've got a <ul> w/ 6 <li> items and CSS to make them 104x228 side blocks, which hold 2 images, one on top of the other. The 6 rows of images look like this:

X X X X X
X X X X X

This is what I want: The top row of images to be opacity:0 (or hidden), and then when you mouseover the bottom images, the top images come to 100 opacity. When you mouseout, the opacity is back to 0.

Here's the HTML and CSS:

Code:

<ul class="carz">
<li><img src="img/impreza2.jpg" class="imgtophidden"/><img src="img/impreza.jpg" /></li>
<li><img src="img/wrx.jpg" class="imgtophidden"/><img src="img/wrx.jpg" /></li>
<li><img src="img/legacy2.jpg" class="imgtophidden"/><img src="img/legacy.jpg" />/li>
<li><img src="img/outback2.jpg" class="imgtophidden"/><img src="img/outback.jpg" /></li>
<li><img src="img/forester2.jpg" class="imgtophidden"/><img src="img/forester.jpg" /></li>
<li><img src="img/tribeca2.jpg" class="imgtophidden"/><img src="img/tribeca.jpg" /></li>
</ul>

The classes are like so:

Code:

.imgtophidden {
opacity: 0;
}
.imgtop {
opacity: 100;
}

I am new to jQuery coding (but loving learning) and I want to figure out: how do I make this in jQuery? Here's what I have so far:

Code:

$(function() {
$("ul.carz li").hover(function() {
	$(this).find('img.imgtophidden').addClass('imgtop')
	} , function() {
	$(this).find('img.imgtop').addClass('imgtophidden')
});
});

Hi,

I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it?

intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\'

I am posting my javascript function he

<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>


function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}

thank you,

I was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on:

Code:

		function handleFileSelect(e){
			var files = e.target.files;
			var output = [];
			for(var i=0,f;f=files[i];i++){
				if(f.type.match('image.*')){
					var reader = new FileReader();
					
					reader.onload = (function(theFile){
						return function(e){
							var span = document.createElement('span');
							span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
							document.getElementById('list').insertBefore(span,null);
						};
					})(f);
					
					reader.readAsDataURL(f);
				}
			}
			document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
		}
		document.getElementById('files').addEventListener('change',handleFileSelect,false);

To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is:

Code:

class.event = (function(arguments){
     //stuff you put in a function...
})(more Arguments?);

I tried to customize a simple one to learn for myself and I wrote this:

Code:

var a = 'A';
var b = 'B';

test = (function(t){
     alert(t);
     alert(b);
})(b);

test(a);

The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused.

The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works.

Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion. Here is the converted anonymous function which fails: https://gist.github.com/2587613 and here is the original anonymous function which works: https://gist.github.com/2587667

Any help would be greatly appriciated

Hi!

I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe.

Link to the page:
Franklin Township Soccer Club - Change Field Status

My sad, sorry attempt =|

Code:

	$( "li.open" ).click(function() {
	$( this ).toggleClass( "closed" );
	});
	
	$( "li.closed" ).click(function() {
	$( this ).toggleClass( "open" );
	});

The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so!

In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission!

I do appreciate any help given!

Dave

I found this script, and it works great:
Code:

<script type="text/javascript">
  function disable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","true");
    }
  }
</script>

I tried to make the inverse by simply reversing the setAttribute() like so:
Code:

<script type="text/javascript">
  function enable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","false");
    }
  }
</script>

But that didn't do it.
Can someone show me why, and how to fix it?

Here's the sample form which I'm trying to test it on:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" /> disable<br/>
  <input type="radio" name="test" onclick="enable('D1')" /> enable<br/>
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" /><br/>
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" /><br/>
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" /><br/>
  </fieldset>
</form>

Edit:
The ultimate goal which I'm working toward now (step by step =) is to have a form more like:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" />
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D2')" />
  <fieldset id="D2">
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D3')" />
  <fieldset id="D3">
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" />
  </fieldset>
</form>

And have the fieldsets enable and disable according the selection of the radio buttons.

Also, the fieldsets (and their ID's) will be dynamically generated via PHP



Thanks-a-bunch,
~ Mo

Thank you in advance if someone can help. I have been banging my head against the wall for hours now.

Here is the code:

Code:

for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
        var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
        var type = {
                value: BS_crm['activityTypes'][i]['id'],
                label: "Add New "+BS_crm['activityTypes'][i]['label'],
                css: BS_crm['activityTypes'][i]['css']+"_16",
                onClick: clickFunc
        };
        previewLinks.items.push( type );

}

Now, basically what I am doing here is running through one array to
create an array of objects, that will be used to create links that
will use whatever onClick function I pass it. The problem is that on
the second line I need the BS_crm['activityTypes'][i]['id'] to be a
value, not a reference. If that line was simply changed to:

Code:

var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };

then everything would work as I need.

How can I make this happen? I would really appreciate any help.

Thank you again in advance.

How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way.
Any suggestions?

PHP Code:
<?php
function phpQuery(){

     $query = mysql_query("INSERT INTO mytable VALUES('','name','email')");

}
?>
<script type="text/javascript">
function delayQueries()
{
  timeoutID = window.setTimeout(doQueries, 2000);
}

function doQueries()
{
  var runQuery = "<?php phpQuery(); ?>";    
}
</script>

I made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example:
Code:

function unhighlight(x) {
x.style.backgroundColor="transparent"
}

Function ActivationFuction()
{
activate.function="unhighlight"
}

thanks
