According to MSDN: "new variables or types defined in the
eval statement are not visible to the enclosing program."
However, in some cases under IIS 5, this is not the case.
Try the following program:
eval("var z = 12; 5;");
Response.Write(z);
According to the documentation this should be an error;
however, it prints "12".
The eval function in JScript doesn't work according to
spec. Specifically, the function C() on page 73 of the
ECMA-262 spec doesn't return the function object
correctly under IIS 5. Binding the anonymous function to
a variable name and then evaluating that works as a
workaround, e.g.
function C() {
return eval("var x = (function (x) {return x*;}); x");
}
works. However, it should be possible to simply evaluate
a function without binding it to a name using the eval
function, especially since the spec has an explicit
example of this.
Is there an equivalent function in ASP which does the same as PHP's eval function?
View Replies View RelatedI basically want to check a multiple amount of form fields to see if these are empty, and if so, set them to "none", but it just doesn't seem to work. and I have tried so many different variants without any luck, mixing the execute command and as below with the eval command.
strChecks = "frm_tel|frm_email|frm_web|frm_infoes|frm_infode"
arrChecks = split(strChecks,"|")
for i = 0 to UBound(arrChecks)
if eval(arrChecks(i)) = "" then
eval(arrChecks(i)) = "none"
end if
next
I've ran into a little trouble with Eval, hoping someone can point it out to me. This code works :
var_ktml = "textarea2"
Set ktml_textarea2 = new ktml4
Eval("ktml_" & var_ktml).Init var_ktml
This code doesn't :
var_ktml = "textarea2"
Set Eval("ktml_" & var_ktml) = new ktml4
Eval("ktml_" & var_ktml).Init var_ktml
Can anyone point out the error of my ways ?
I have some code that checks security permissions in a DB, and before my conditional statement that checks these permissions, I am writing out both values to see what the statement looks likebefore it is evaluated.
The problem is, it seems to disregard the condition and always returns True, even if the condition should be false...any ideas? I also did some testing to assure that the length of the two values I am comparing is 1, just in case they were possibly holding spaces, and I verified they are numeric as well. I am just stumped here...
Let me also preface this code snippet by saying, I am using this asp script to generate javascript menu choices...and I did include some commented debug statements so I can see what the javascript rendered.. Code:
I've been doing some reading up on ASP.NET and have come across something that really scares me. One of ASP.NET's "big new things" are ASP.NET Controls. These seem to be shortcuts for developers so, for example, you can place a Validator object on the page and specify a few parameters and ASP.NET will write all of the html/javascript for you. The reason this scares me is it seems that Microsoft is taking ASP.NET the route of Frontpage, which liked to insert code that was not very cross-browser complient.

View Replies View RelatedWould anyone be able to confirm that 'jscript.dll' is a necessary file for an .asp page on IIS 5.0 to use the <script language="JavaScipt" runat="SERVER"code? It looks like the code in this section is not working and being recognized since it keeps giving me:
"Microsoft JScript runtime (0x800A01B0)

I've started implementing my ASP pages (in JScript) using the Try/Catch error handling.
Mostly it is working very well. It gives a nice custom error page which looks somewhat more professional than the default.
However there seems to be one limitation, the error object thrown to the catch statement doesn't include the line that the error occured on. Is there any way to obtain this information?
How to convert this from vbscript to jscript?
MBRequest("File1").Save
MBRequest is a script component
I am used to doing this in VBScript. But I am not able to get this to work in JScript.
My code simply tries to add 1 a variable which holds a char and parse into an int. But instead of a value of 2 for an addition for 1+1, I see 11.
sCount = Request.Querystring("Count");
//sCount outputs a value of 1
sNextCount = parseInt(sCount + 1);
Response.Write (sNextCount);
//outputs 11 instead of 2
Is parseInt wrong?

I need to do some client-side scripting for my Intranet and was wondering if
Jscript or Javascript would be better? Everyone here uses IE 5.0 +, so I
need to make a decision...
I currently thinking of converting from my little knowledge of
VBscript to jScript ASP.
With this in mind I'm looking at my current code to see how it will
convert over to Jscript.
One thing I have spotted that I can't think of a way round is the ADO
recordset.GetRows command.
I have a VBscript class that handles my DB connections so in short I
can do things like
MyArray = clsDB.GetRecordsInArray("Stored Proc Name/SQL", other
params)
and this would return the rows into a 2 dimension array.
Problem is I've read that Jscript only has one dimension. So how is
the "getRows" solved for Jscript.
Also is there any good "Jscript" code learning sites?
I have this string:
/sites/binaer/demo/fil/Winnie-the-Pooh 1024x768.jpg
If I wanted to cut everything before Winnie-the-Pooh 1024x768.jpg, how would
I do this?
In VBScript I could find the first "/" from the back of the sentence, and
cut everything before that, but I'm not shore how to do this in JScript...
The string I want to end up with is Winnie-the-Pooh 1024x768.jpg
Any idea??
I'm stating out doing some web developing. I Know CSS, HTML, T-SQL. I can look at the client javascript code and work out what it does but I can't really write it from scratch.
I know mainly VBscript. I was wondering should I drop VBscript and learn Jscript then code both the client & server code in Javascript/Jscript. I have a couple "CLASS" files in VBscript and was wondering how does Jscript do this ?
I am quite frustrated. The mai9n reason is because I don't understand how internet works. I know VBScript and I know a little bit of Jscript. I began a program (website) with vbscript (ASP) and after coding some files, i found out that it ain't cross-browser compatible so I decided to switch to JS. Now I have started to use JS in ASP and this is what TimLensen said.
You could convert it to serverside Jscript but I wouldn't recommend it since not much asp apps are written in Jscript these days, it doesn't really have a point either. Learn the basics of asp at w3schools. Don't just look at the code and copy it and change it a bit but try to understand how the internet works.
