Consider the following line of code...
var path = location.pathname;
...after execution, the variable "path" contains something like
"file:///C:/Documents%20and%20Settings/user/Desktop/Test/fileread.htm"
How do I parse this down to "C:\Documents and Settings\user\Desktop\Test"
...or at least to "C:/Documents%20and%20Settings/user/Desktop/Test"
Is there a better function to retrieve the source folder containing the
current HTML document?
I need to know the path to the current folder to reference other files in
the same directory using a FileSystemObject.
Thanks!
Hi Phred,
I used a different variable name because "path" looks too much like a
reserved word to me.
p="file:///C:/Documents%20and%20Settings/user/Desktop/Test/fileread.htm";
alert( p = p.substring(p.indexOf('C:'), p.lastIndexOf('/')) );
while( p.indexOf('/')+1 ) p=p.replace(/\//,'\\');
while( p.indexOf('%20' )+1) p=p.replace(/%20/,' ');
alert( p );
Different string method are used here, to begin with indexOf and
lastIndexOf. You can hardcode the string 'C:' only if you are certain
everything will indeed be under C...
These two methods return integers, numbers that is, which form the arguments
for the third method, the substring, which cuts off the superfluous bits at
start and end.
The bit "p=p.substring(...)" not only assigns a value to p, but also returns
this value to any function willing to receive it. In this case there is one:
the alert is which the whole is wrapped.
Next two lines cycle through the variable, replacing matching substrings as
they go. The first argument of the replace method is a regular expression.
These are often delimited by slashes instead of quotes, and can have a
global and case insensitive flag.
Because it is slashes we are looking to replace, these must be escaped
inside the regex string. Special characters are escaped by preceding them
with a backslash. The backslash is also a special character.
No alpha characters here, so case doesn't matter, and I opted for the while
loop instead of the global flag for when you start using double spaces in
your urls.
The global flag doesn't catch immediate repeats.
