FAJAX

FAJAX or Fake-Ajax is an implementation that forces IE to render page in a different manner. It has the word "AJAX" in it because you get rid of that nasty page load effect that gives you a blank screen until the content is loaded in browser instance.

 

All you have to do is, add a <meta> tag in <head> element of your HTML page. Transition can be applied at 4 stages...

Page Enter

Page Exit

Site Enter

Site Exit

 

Meta tag for same are as following...

meta http-equiv=”Page-Enter“
meta http-equiv=”Page-Exit“
meta http-equiv=”Site-Enter“
meta http-equiv=”Site-Exit“

 

In a simple implementation, you can use the following tags in head element to avoid flicker...

<meta http-equiv="Page-Enter" content="blendTrans(Duration=0)">
<meta http-equiv="Page-Exit" content="blendTrans(Duration=0)">

 

And if you are interested in some more effects, you can use DirectX Transformations and add some flavour to your site.

Example...

<HEAD>

<meta http-equiv=”Page-Exit” content=”progid:DXImageTransform.Microsoft.Fade(duration=.5)” />

</HEAD>

The way I understand this works is that IE sends a request for the new page but does not clear the page you have on your screen right now. When IE has the second page ready in the buffer, it just uses DirectX to transform the image of the previous page into the image of the new page.

 

 

You can try these other effects too :

content=”progid:DXImageTransform.Microsoft.Wheel(duration=0.5,spokes=5)“
content=”progid:DXImageTransform.Microsoft.Barn(duration=0.5,orientation=horizontal)”
content=”progid:DXImageTransform.Microsoft.Blinds(duration=0.5,bands=5)”
content=”progid:DXImageTransform.Microsoft.CheckerBoard(duration=0.5)”
content=”progid:DXImageTransform.Microsoft.Fade(duration=0.5)”
content=”progid:DXImageTransform.Microsoft.GradientWipe(duration=0.5,wipeStyle=0)”
content=”progid:DXImageTransform.Microsoft.Iris(duration=0.5,irisStyle=STAR)”
content=”progid:DXImageTransform.Microsoft.Iris(duration=0.5,irisStyle=CIRCLE)”
content=”progid:DXImageTransform.Microsoft.Pixelate(duration=0.5,maxSquare=40)”
content=”progid:DXImageTransform.Microsoft.Wheel(duration=0.5,spokes=5)”
content=”progid:DXImageTransform.Microsoft.RandomDissolve(duration=0.5)”
content=”progid:DXImageTransform.Microsoft.Spiral(duration=0.5)”
content=”progid:DXImageTransform.Microsoft.Stretch(duration=0.5,stretchStyle=push)”
content=”progid:DXImageTransform.Microsoft.Strips(duration=0.5,motion=rightdown)”

Get rid of Page Transitions

 

Recently I was facing this problem. I used AJAX in .NET and posting was very smooth without any flicker. But the page transitions were painful. So I found this small piece of code over net.

 

This is two line implementation that will reduce page flicker during transition to minimum possible time. The only flicker that will remain intact will be if you are using heavy images on page. For textual stuff, you can never judge the difference.

 

Put following lines in the <HEAD> element of HTML page.

<meta http-equiv="Page-Enter" content="blendTrans(Duration=0)">
<meta http-equiv="Page-Exit" content="blendTrans(Duration=0)">

 

Now I am trying to display a loader during page load. I know that this is very easy as we are just calling a javascript function during Page-Enter and Page-Exit. I can call my own javascript function during these events who will start loader and then call blendTrans function.

I'll do it soon and will post that code over this blog as well.

 

By the way, this technique is called:

FAJAX

or

Fake-Ajax

 

Happy Coding
