script language = "js", "jscript", "javascript ", "vj#" What to use

[RFS666]

Hello,

I would like to use variables with a type in jscript.NET.
I declare them as follows:
var x : double = 5.03;

This doesn't work in my script, that I write to the page in codebehind with
"registerClient ScriptBlock" as follows:
string script = "<script language=jscrip t>";
script += "function test()";
script += ...
Page.RegisterCl ientScriptBlock ("usefulName ", script);

I can only use untyped variables like "var x = 5;" in these scripts what is
not useful for me.
For each function in the registered script block, I add an onclick-event to
a webcontrol button:
button1.Attribu tes.Add("OnClic k", "return function1();");

This works when using the statement <script language="jscri pt"> in the
script block that I want to write to the page with
"Page.RegisterC lientScriptBloc k"

But when I change the script language to "js", the functions are not called
anymore when I click the corresponding buttons. An error message appears,
that an object does not exist. But with "js" as script language, I can use
variables with a type.
The same with the "vj#"-tag

With the one tag (vj#, js) , I can use variables with a type, but call no
functions,
with an other tag (jscript, the one I am using), I can call the functions,
but use no typed variables.
I need both "features", so I hope, somebody can tell me what I'm doing wrong.
As variables with a type are only available since jscript.NET, I don't know,
if
<script language="jscri pt"> specifies jscript.NET.

I hope somebody can help.

Thanks in advance & kind regards

not sure if you are getting a bit confused abt the client side and server
side programming..

the jscript.net is for server side programming... the code should be either
in <script language=jscrip t runat=server> block or in a code behind page...

This is client side script. I don't know if possible but even though it
would run only if the browser has .NET installed. IMO stick to javascript
for client side scripting...

Found :

Although browsers support most JScript .NET features, the new features that
target the .NET Framework, class-based objects, data types, enumerations,
conditional compilation directives, and the const statement, are supported
only on the server-side. Consequently, you should use these features
exclusively in server-side scripts.

So it looks like this is javascript client side and Jscript.NET server
side...

Ok,

thanks for your replies. Now, I'm sure, that I use clientside scripting.
The codebehind file is in C#, but I've read that this is also called
"serverside scripting". This is very confusing for me, as I didn't consider
C# as a scripting language. I think it depends on the perspective. I should
mention that this is my first project with a scripting language. Ok, let's
go...

There are three ways to use clientside script (I think):
in <script> </script> block in an aspx-page or in a separate .js-file with
<script src="filename.j s"> (in the aspx-page too) or dynamically created in
codebehind with Page.RegisterCl ientScriptBlock or Page.RegisterSt artupScript.
I use the second and the third.

The third brings me to the following problem.
I need a double value in a jscript-variable, whose value I comes from a
codebehind double-value as follows.
script += "<script language=jscrip t>"
.....
script += "var aDouble = " + "\"" + aDoubleFromCodb ehind + "\"" + ";";
.....
Page.RegisterCl ientScriptBlock ("usefulName ", script);

The problem is, that this assignment implicitly casts the double value that
comes from codebehind to a string. If I omit the two "\"", I receive an error
message on page_load:
Error: identifier expected

I also tried a conversion with:
script += "var aDouble = (Number)" + "\"" + aDoubleFromCode behind + "\"" +
";";
but this gives me the following error message:
Error: ';' expected.

I can't believe, that explicit casting is not possible at client side.

So, I hope, somebody can bring some clearance into this

Thanks in advance & best regards

If your double value holds 2.5 you'll want to create the following ligne :

var aDouble=2.5;

So just suppress the double quotes for a start...

It's not - JavaScript (like VBScript) has only only type of variable:
variant.
So, I hope, somebody can bring some clearance into this

var dblTest1 = "100.12";
var dblTest2 = "10.1";

alert(parseFloa t(dblTest1) * parseFloat(dblT est2));

I think, I found out what the problem with:
script += "var aDouble = " + aDoubleFromCode behind + ";";
is:
After receiving the error message and starting the debug mode, I realized,
that the double value contains a comma instead of a point: 0,8 instead of
0.8. But the double variable in codebehind contains a point, so where comes
the comma from? I cannot influence it.
Could it have something to do with the codepage of the aspx-file?

Thanks & regards

Don't worry was expected ;-) Now that I'm sure that you don't work with the
decimal point, let's proceed with the next step :

DoubleValue.ToS tring(System.Gl obalization.Cur ltureInfo.Invar iantCulture)
(of course you can do an import to shorten the expression).

It will write down the value with the decimal point instead of a comma.

The problem is that as soon as you write down values such as decimal and/or
date, the text representation depends on national settings. The default
culture is defined in the web.config file and is suitable for displaying
data unlike programming languages. The InvariantCultur e allows to avoid
using the current national setting...
