I would like to set opacity of some element to 0 through JavaScript, using GetElementById function. This is my short code inside body of HTML:
<script>
document.getElementById("element").style.opacity="0";
</script>
<div id="element">
noopacity
</div>
It doesn't seem to work, what am I doing wrong?
i am working with opacity. i dont want to include child tr with the table element opacity.
View 1 Replies View RelatedIn order to design a custom select element look in my site, I was messing with the css and opacity value to fade the actual select box and put a background image in a div right above the select element. The functionality of the select box is preserved no matter if opacity is set to 0, so I was able to accomkplish my goal.But, that worked for every other browser around except IE6.Is there a please someone there that encountered this problem and possibly knows some kind of workaround?
View 2 Replies View RelatedI recently wrote some code, which involves a list. Elements can be picked by up/down arrow keys.To highlight the elements, I'm using a similar call to objects[focus]stop (true,true).animate({'opacity': 1}, 200);(As you can see, all DOM elements are cached)the same call goes to the element which lost the focus, with an opacity value of 0.2.Whatsoever, I noticed on testing that the performance is just fine on firefox 2/3, IE 7/8, even Safari has good results.Only exception so far is Chrome, it's terribly slow on those calls with a CPU load of 40-50%.I didn't further investigate that behavior since it still works "OK" on Chrome, but SIGNIFICANT slower.
View 12 Replies View RelatedI've been trying to get opacity reporting working in IE 5.5 but the
Microsoft documentation does seem to work as I interpret it even though
this documentation page seems have been written for IE 5.5
<URL: http://msdn.microsoft.com/workshop/author/filter/filters.asp>
In the html page listed below I see an error "Library not registered"
in IE 5.5. In IE 6 I see an alert that says "50" as expected.
Some of microsoft's demos on the above page also show the "Library not
registered" error in IE 5.5 but work in IE 6.
Has anyone else experienced these problems with filters? Any idea why
IE 5.5 doesn't work as advertised? Code:
In IE I have a routine that dynamically assigns objects' opacity. This works
fine for some elements but not for others.
It works for buttons and inputs but not for img, span and select.
This is the line that sets opacity from a loop through all elements:
document.forms[0].elements[i].style.filter =
"progid:DXImageTransform.Microsoft.Alpha(opacity=" + FadeOpacity + ")";
I want to amke something fade out, if and only if it is already set at 100% opacity.
I need to make a function that will allow me to do this.
Here is my current code:
//Time=millisecond Start and End = Amount of Opac to start with. Id = which div to affect
function opacity(id, Start, End, time) {
//frame speed here
var speed = Math.round(time / 100);
var timer = 0;
//
if(Start > End) {
for(i = Start; i >= End; i--) {
setTimeout("Opac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
} else if(Start < End) {
for(i = Start; i <= End; i++)
{
setTimeout("Opac(" + i + ",'" + id + "')",(timer * speed));
timer++;
}
}
}
function Opac(opacity, id) {
var obj = document.getElementById(id).style;
obj.opacity = (opacity / 100);
obj.MozOpacity = (opacity / 100);
obj.KhtmlOpacity = (opacity / 100);
obj.filter = "alpha(opacity=" + opacity + ")";
}
How would I write a function that would allow me to fade out if opacity was already 100, otherwise it does nothing?
I've got two problems with these functions:[code]The first is that they fade in and out as expected, unless I mouse over any of the text in the div. Then the fadein and fadeout functions seem to compete with each other.The second is that showcount keeps getting set to undefined, so it never gets to 4, where upon fadeout should return without fading the div into the background.I should say that I believe the first problem has to do with mouseover seeing the html as a separate entity from the div, but that seems odd because it's a child of the div!

how to implement it in a site with a mouseover, mouseout events?
here is my [URL].. Basically when mouseover I animate the opacity. Works well in Firefox but in IE 8, the shadow appear on the text. Is there anything I miss out or is there any problem with my PNG file?

View 2 Replies View RelatedI have a bunch of thumb nails that will be at full opacity when a user gets to the page. Users will be able to select their favorite. What I want to have happen is when a user selects their first favorite all of the there thumbnails will be lowered in opacity then when they select other favorites the opacity of that thumbnail will be brought to full. Each thumbnail is in a div. I am at a complete lose on how I can achieve this.

I want to show a few products, (3 columns x 2 rows), when user clicks some links (LINK 1, LINK 2, LINK 3), these productos change for another six.
To show new products, Im using scriptaculous opacity effect. Everything works correctly on firefox and chrome, but on IE it shows 1 column x 6 rows.

I've been told i can use the jQuery effect fadeTo() which will work, however i'm not sure how to adapt my animate() code to use the fadeTo() function at the same time as moving.
I have a real problem with the google maps API in IE7/8, the "powered by google" which i can't remove due to the t&c's loses its alpha transparency when i apply opacity to it "to acheive the sliding in effect" seen here: [URL] I'm trying to set the alpha back using this:
Code:
$('#map_canvas div div a div div').css("filter","progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop,src=http://maps.gstatic.com/intl/en_gb/mapfiles/poweredby.png)");
(jQuery)
But this does not seem to do anything, and looking at the source in firebug Lite for IE, it seems this is already set on multiple div's surrounding the logo anyhow.
I am writing a small script to fade the opacity of an image/object.
The script itself works fine only I do have some unwanted behaviour.
I do use a tablecell object and the mouseover/mouseout to activate the
script.
In the same cell are some links listed and when you move the cursor
over the links the image starts to flicker. This is because of the
getElementById that identifies each link as an object.
Anyone knows how I can solve this behaviour? (Below is the sourcecode I use)
I cannot succeed in getting any key event on a div that's been set
invisible by the style's MozOpacity property under firefox. I'm using
this method so that I can capture the mouse events. Unfortunately, it
appears to do so only with mouse events, not key events.
Is there a better solution than the following?:
I have several images as thumbnails on my page and applied the 'changeImg()' function the onmouseover event. It then shows the thumbnail image as 'big' image at a certain position. It looks kind of boaring and it would be nice to apply jquery to have a nice effect problem: after quite some time I still don't seem to be able to integrate it into the existing javascript function.
