Preserved Topic: javascript (Page 1 of 1)

is there any servers besides the netscape ones that support server side javascript

You can use JScript & VBScript in Microsoft ASP (Active Server Pages - similar to PHP)...

when u use jscript with asp does it have the same objects as if u were using vbscript....session etc...

btw i was wondering if it was possible to have static variables in a javascript

btw i was wondering if it was possible to have static variables in a javascript functions

on the server side?

either , i thought the core language was the same for both

For all questions about ASP, visit Microsoft's web site...

• http://msdn.microsoft.com/asp/
• http://msdn.microsoft.com/library/default.asp?URL=/library/psdk/iisref/aspguide.htm
• http://msdn.microsoft.com/net/aspnet/

Not many of us here support ASP...

It is just an ugly language (IMO)

Just a small correction to WarMage's post above. ASP *is not* programming language. ASP is server-side technology used for creating dynamic web sites. ASP relies on other programming languages when generating pages. At the moment you can use VBScript and JScript (both of them are Microsoft creations) to program ASP pages. And it's a well known fact that Visual Basic is the worst programming language ever invented. VB is the thing that sux here, big time!

You can't really have static variables in JavaScript. You can certainly pretend a variable is static, by not changing it, but it's not *really* static.

i found a way to simulate a static variable

test.variable=0;
function test(){
variable++
}

A static variable is a variable that stays the same over all instances of an object class, correct?

How completely does javascript support OOP restrictions such as private & static variables?

I'd have to think not very.

I've never used JS on the server side so I'm not aware of any differences.

In regards to scope. I (and most) don't use the "var" keyword. it's been my experiece that any variable set without the var keyword is global in scope. whether defined within a function or outside in the general scripting space.

randy.

I don't believe you need the "test." in this example. it should work fine
like so:

variable = 0;
function test(){
variable++;
}

I believe assigning the varaible within a function using "var" makes it local to the function.

I'm just writing this off the top of my head though

Oop! I was confusing "static" with "constant". Yeah, if you want a variable that remains the same the next time you call a function, you just want to define it *outside* the function, in a larger scope.

var myvar = 1; // myvar is defined outside the function, so it's remembered before and after the function is called.
function doSomething()
{
myvar = myvar + 1;
alert(myvar);
}
doSomething(); // alerts '2'
doSomething(); // alerts '3'

(sorry slime you had var = var+1 not trying to step on toes)

Yeah, I think the concept of a static variable doesn't make much sense if you aren't defining classes. In a situation like this, a global variable would seem to be the appropriate method...

while on the subject of javascript i was wondering how to set a block of javascript to execute after a certain defined period of time.

setTimeout()

easist thing to do is wrap the block of code in a function and then use setTimeout()

setTimeout('function()','time in ms');
I like to name my timeouts

myvar = setTimeout('myfunc()',3000);

because then you can clear them like so
clearTimeout(myvar);
