Subject: [Javascript] Pre-load images
Message-ID: <p06240807c4c8c027e384@[192.168.1.101]>

Hi gang:

I have a script that pre-loads images (who doesn't?).

Without the pre-load, I get major flashes on image roll-overs.

With pre-load, it cuts the flashes down to almost nothing. But I 
still notice flashes occasionally on image roll-overs  -- is that to 
be expected? Is that a browser thing or should it not happen at all?

Thanks,

tedd

I don't know what your images are like, but have you considered image
sprites as a solution to "rollover flash" ?

If you are using CSS for image rollovers, this might be of interest as well:

This can happen if you clear the browser cache while your page 
containing the rollover is still open...
When you go to the open page, call the rollover again, the image is not 
there anymore so the browser calls the image again and that's probably 
why you get the flash...
The simplest explanation I have from my experience...
Hope this helps.

I don't.

If I need to pre-load images, I put them in a DIV that's off-lefted
(use your favorite off-left technique for this.) For good measure,
I include image attributes '<img ...width="1" height="0">' --
but this may not be necessary.

There is some JS mumbo-jumbo that can take care of this[1], but
I suggest putting a far future "expires" header on your images if you
can. This not only prevents the browser from trying to download images
a second or third time, but improves the speed of your pages on
subsequent visits:

Message-ID: <0K5V0046D35TQUD0@mta5.srv.hcvlny.cv.net>

I was wondering how folks handle the case where the document has not yet
loaded and you want to manipulate dynamic elements and do things like resize
the frame in an onload trigger function.

 

What I wound up doing was seeing if critical elements existed yet and things
like checking the height of an image to make sure it's loaded.

 

I wasn't sure how else to see if the document was ready in the onload
trigger.

 

Better ways?

 

I found a jquery dom.ready function, but I didn't want to download jquery
just for that.

It would be a general thing.

Ajax in the classic form creates an xml object and calls a php script.

When the server finishes with the php script, it returns xml.

However, if the page that originally called the php script is no longer in
the client's browser and error is generated by the xml.

You can look at the website: http://www.wantedgaming.com/shop.

Click the right box alternating breaking/game news over repeatedly.  They
are both ajax pages.  Eventually, the xml error will occur because the
client is switching out the pages faster than the server is returning the
xml object.

Maybe, I should switch to the script element version of Ajax instead.

This would not be a normal use of the website.

Not quite. In the classic form, it creates an XMLHttpRequest object  
and makes a request to the server, which returns XML. XML doesn't need  
to be passed, and PHP doesn't need to be used to generate the response.

These days (i.e. the non-classic form), its generally accepted that  
Ajax means any use of JavaScript to make an HTTP request and update  
the page based on the response.

The XMLHttpRequest object should have been destroyed when the browser  
discarded the page. The response from the server should be ignored.

I can't reproduce the problem. The only complaints my debugger gives  
are warnings that you are using document.all.

Hey Nagendra,
A little heads up it wud have been mentioning the browser causing this
problem.
The snippet (provided by u) works well on FF.
A little bit of googling, makes me arrive to the following snippet to make
it work on IE:

<html>
> <head>
> <script>
> function foo(){
>     var d = document.createElement("div");
>     d.innerHTML = "<nobr>aaa</nobr>";
>     document.getElementById('aaa').appendChild(d);

Hi Nagendra,
 
This is an example of bad nesting of html tags.
Are you presuming that your code is correct?
 
<nobr> is a proprietary html tag.
Never a part of any standard.
 
Have you tested if <nobr> can have children?
 
On what base do you expect that you can put a block level container
element inside a nobreak tag instrucion, when next first encountered
element is a generically line-breaking element.
 
Using <nobr><div>... is frankly illegall, but
<div><nobr>...content...</nobr>...content...</div> might be. 
 
Try nesting your elements the correct way.
 
Cause there's no logic, nor a practicall reason in placing a <div> inside
a <nobr> tag. For what purpose?
 
The 
<div id='aaa' style='display:inline;'><nobr>...</nobr></div>will work hust fine, but will not validate.
 
consider using css white-space:no-wrap instead.
 
Regards

Message-ID: <8c6efe180808291939h3be3fce4s7095c4556e4c24ce@mail.gmail.com>

Hi,

In my aspx page, I have two tabs. I have written a javascript in such a way
that if the user clicks on first tab, it will go to the previous page
visited and that will be the required behaviour which is working perfectly
fine.

Sometimes the previous history will not be available. In the sense, there is
an option that the user can directly visit the page by making changes in the
url without going to login and home page. In such a case, I need to show the
user the home page. How will I do that? Can anybody provides any logic to me
for this?

I have used the following JS code for going to previous page.
function UltraWebTabMain_Click(oWebTab,oTab,oEvent)
{
var wTab = igtab_getTabById("ctl00_TabControl1_UltraWebTab1");
if(wTab!=null)
{
var tab = wTab.getSelectedTab();
if(tab!=null)
{
var tabtext = tab.getText();
var FirstTab = 0;
if ((oTab.Key == "Search") && (tabtext != "Search"))
{
window.history.go(-1);
wTab.setSelectedIndex(FirstTab);

}

}
}
}

Can I do any modification to the above JS code so that the user should be
directed to Home Page if history not present? Can anybody provide any help
please?

Thanks

Subject: [Javascript] Need Javascript logic for going to homepage if
theprevious history not available

Hi,

In my aspx page, I have two tabs. I have written a javascript in such a way
that if the user clicks on first tab, it will go to the previous page
visited and that will be the required behaviour which is working perfectly
fine.

Sometimes the previous history will not be available. In the sense, there is
an option that the user can directly visit the page by making changes in the
url without going to login and home page. In such a case, I need to show the
user the home page. How will I do that? Can anybody provides any logic to me
for this?

I have used the following JS code for going to previous page.
function UltraWebTabMain_Click(oWebTab,oTab,oEvent)
{
var wTab = igtab_getTabById("ctl00_TabControl1_UltraWebTab1");
if(wTab!=null)
{
var tab = wTab.getSelectedTab();
if(tab!=null)
{
var tabtext = tab.getText();
var FirstTab = 0;
if ((oTab.Key == "Search") && (tabtext != "Search"))
{
window.history.go(-1);
wTab.setSelectedIndex(FirstTab);

}

}
}
}

Can I do any modification to the above JS code so that the user should be
directed to Home Page if history not present? Can anybody provide any help
please?

Thanks
