Board index » Web Programming » Escaping escape characters in JScript

Web Programming261
Hi,



I have been getting hopelessly confused with escaping escape characters in

JScript! All I want to do is write a simple funtion:



function DoubleUpBackSlash(inputString)

{

???????

}



which will do the following:



<%

var inputString = "D:\Internet\test2.txt"

Response.Write(DoubleUpBackSlash(inputString));

%>



...printing out the following on the screen:

D:\\Internet\\test2.txt



Can anyone fill in the blanks in the function for me?



TIA,



JON

By the time you're passing the value to your function, you have to already

have the \s escaped. So, if you're hard-coding in the string value, which

you're currently doing, hard-code it with the \s doubled up already.



What are you trying to do with the value afterwards? Are you putting it in

a client-side javascript function? If so, escaping will have to be handled

again, but tell us what you're doing first before we worry about that.

Hi Ray,



This is what I'm after (see my comments in the code):



<%

var fso = Server.CreateObject("Scripting.FileSystemObject");



//doesn't work

var wfile = fso.CreateTextFile("D:\Internet\test2.txt", true);



//works

var wfile = fso.CreateTextFile(" D:\\Internet\\test2.txt", true);



//want this to work!

var wfile =

fso.CreateTextFile(DoubleUpBackSlash("D:\Internet\test2.txt"), true);



wfile.WriteLine("This is a test.");

wfile.Close();

fso = null;

%>



Thanks,



JON

The //want this to work won't work in jscript! Is there any particular

reason that you don't want want to use the built-in escape functionality

that is required? You can't just elect to not use it. If you share the

reason for your desire, you may be surprised by a creative solution!

Unfortunately, it can't be done. It's the equivalent of trying to create the

DoubleUpQuote function in VBScript. By the time you construct the string to

pass to the function it's already too late. Sort of a weird catch-22

situation.

If you are supplying a string literal (as above) you would have had to

already have typed in the \\ in order to get the string properly

interpreted. It's the same as if you typed in a string literal containing a

quote in vbscript:



s = "he said "something""



This would not be correctly interpreted either until you doubled the quotes.

s = "he said ""something"""

Hi Ray,



Reason's simple - it was a pain in the you-know-where copying file paths out

of a browser address window and manually doubling up the back slashes, so I

just thought I'd try to automate the process instead...



Cheers,

Hi Bob & Chris,



Thanks, that explains what was screwy in my logic!



Cheers,

Wouldn't the browser address use a /?



If your values are already in variables, you don't have to escape the \. If

you have a variable with a value of "D:\Path" you don't have to escape that.



Again, if you show us what you're doing, you may find an answer.

Sorry Ray, I meant the Windows Explorer address bar, not browser address

bar.

How are you pulling in a Windows Explorer address bar from ASP code?

The backslash indicates the following character to be printed as is. In

this case you just have "D:Internettest2.txt". However, you may use

another web typical syntax with slashes:



fso.CreateTextFile(makeLocalePath("D:/Internet/test2.txt"), true);



function makeLocalePath(path) {

return path.replace(/\//g,"\\");

}

I'm not doing it from code, I'm doing it with the help of a mouse....



I think Bob & Chris, in another branch of this thread, have explained that

what I was trying to do is actually impossible...

Thanks, Daniel.

Daniel Kirsch <Iwillnotread_daniel@gmx.de>writes:



Actually, a backslash followed by another character together form an

"escape sequence", which stands for a single character. Some escape

sequences for non-printing characters are

\n - newline

\r - return

\t - tab

(there are more, but not many). For characters which are not defined

as part of a special escape sequence, the escape sequence just becomes

the second character itself.



So, in this case, "\t" becomes a tab character, and you have:

"D:Internet est2.txt"

^ This is a tab character, ASCII 8.
