Reply to: Ajax anyone know anything

[Sysman]

IF you roll your own Ajax (which I do, by preference) you get nice trim efficient packets of data (JSON, XML, pipe-delimeted, whatever you want) - .NET Ajax has wrapped up the nice simple functionality in its usual MS Bloat, sends back Viewstate and a whole load of other gubbins with every call, and a whole load of gubbins comes back - much MUCH more than is actually required to implement the dynamic client changes.

Good 'ole MS, got to keep those PC sales going, haven't we?

It's worth noting that older kit can be painfully slow with Ajax stuff. It's something to consider if your site is aimed at Joe Public or international audiences. This is something the BBC hasn't cottoned on to with their "Please turn on JavaScript. Media requires JavaScript to play." messages.

Well, presumably the Ajax calls to the server will just return a bit of JSON for the client JavaScript to deal with, thus avoiding all that .NET mumbo-jumbo completely - which has to be an improvement straight away.

the big sell is that it will improve client side performance, what about that ?

Depends Beware using MS Ajax, it will send back a Viewstate + other lengthy gubbins on every call, even if you just want to update one lousy little textbox.

It saves screen refreshes, but it makes your http traffic bitty.

ahhh is not a programmer what

morning all,

one of the .net components is going to support ajax

I am told it will improve performance server side by upto 30%

anyone know anything about it ?

Milan.

If you cannot research this much, I am not too confident you can implement the technology.

Mind you, these days all programmers copy the code by googling for it.

So they finally bought the auto tape changer then?

...and what about Vim?

Off to technical with you!

This is Milan we're talking about. I don't think Technical is the right place for him

As an Ajax developer of several years experience, I can tell you that it won't improve server side by anything much at all.

Well, presumably the Ajax calls to the server will just return a bit of JSON for the client JavaScript to deal with, thus avoiding all that .NET mumbo-jumbo completely - which has to be an improvement straight away.

Although they do say that a lot of people have JavaScript switched off, or use browsers that barely support it, especially AJAX. Something like 2 in 10 users I heard the other day, which seems absurdly high, but that's what they said. If you include mobile browsers, games console and TV based browsers and old browsers which people keep for years and years without updating.

Ajax couldn't beat Hector.

thanks Dim,

not too worried

we're gonna put it in anyway

another thing new and shiny for the cv

Milan, if you want a sensible answer from people who know what they are talking about technically, rather than a bunch of chancers who are only in it for the money, try a professional technical forum.

If you want to know about Global Warming, immigrants, tax rises and the life of sock puppets, you are in the right place.

Ajax? Wasn't that what Colin Grigson thought Alan Metcalfe's Bad News alter-ego was and not Vim (Fuego)?

"OK then. it's my brother's PA and I say you all can't use it..."

[milanbenes]

BigYinYang,

well .net said it would and the customer wants it

so that's good enough for us :-)

onwards an upwards

Yep. General Kala dispatched the war rocket Ajax to retrieve Flash Gordon’s body, thinking that Flash had died in the rocket attack. But Flash survived, giving us the immortal line ‘Gordon’s alive’.

Then Gordon saved the world.
