[chuck clark]

Hi,
I would like to enter a folder path like this
C:\Documents and Settings\chuckl arge\Desktop
and get this
C:\\Documents and Settings\\chuck large\\Desktop\ \

this is what i have tried but can not get it right

function preparePath(fol derPath)
{ var len = folderPath.leng th;
if(folderPath[len - 1] != '\\')
{ folderPath += '\\';
}
return folderPath.repl ace(\\, '\\\');
}

sourceFolderPat h = preparePath("C: \Documents and
Settings\chuckl arge\Desktop");


Any Help is appreciated,
Chuck

Here ya go... I think you are getting confused about escape characters.
Whenever you have a string with a \, there needs to be another
character, so "\\\\" evaluates to \\. In your function, you are
replacing \\ with "\\\" which is guaranteed to break, since you are
escaping the second double-quote, and the string never closes.

Also, in your test, you need to add \\ in the path, because it will be
evaluated as \ before you send it into the function. _THIS IS
DIFFERENT_ from if you are handed a string with a \ in it. The escape
character \ is only used by the inputting user.

function preparePath(fol derPath)
{
if(folderPath[folderPath.leng th - 1] != "\\")
folderPath += "\\";

return folderPath.repl ace(/\\/g, "\\\\");
}

sourceFolderPat h = preparePath("C: \\Documents and
Settings\\chuck large\\Desktop" );

folderPath = folderPath.repl ace(/\\/g,"\\\\");
