File Directory Dialog Box

[rockocubs]

Is there a way in Javascript to bring up dialog boxes for both opening and
then also saving a file?

You can. On Windows-boxes, you can use any language supported by the
Windows Scripting Host. E.g., make a file called "test.js" containing:

alert("this works!");

and run it with "wscript test.js".

However, Javascript itself has no method of working with files, or any
other I/O for that matter. All of that is provided by the environment
the script is run in. The environment in browsers is the one assumed
by people in this group unless something else is stated.

If you run your scripts using "wscript", you should consult the
documentation for the Windows Scripting Host to find out what features
are available.

and run it with "wscript test.js".

And get the error:
Script: \path\test.js
Line: 1
Char: 1
Error: Object expected
Code: 800A138F

The error encountered above is precisely because of this fact. alert()
is a method provided by the default global object to scripts executing
in Internet Explorer. alert() is not a method available to scripts
running in wscript/cscript because the host does not expose/provide such
a method.

To popup a dialog in wscript, you'd use:

WScript.Echo("t his works!");

(note this echos to the console when the script is executed with cscript
test.js).

To have a version that does the equivlent of alert() for both wscript
and cscript, you'd use:

var wshShell = new ActiveXObject(' WScript.Shell') ;
wshShell.Popup( "this works!");
If you run your scripts using "wscript", you should consult the

Indeed.

For relatively clean list of available WSH objects, properties and
methods, I prefer <url:
http://www.devguru.com/Technologies/...h_objects.html />

All the objects available there are instatiated (with the exception of
TextStream, which is returned by the StdErr, StdIn and StdOut properties
of the WScript object) in JScript using:

var wshWhatever = new ActiveXObject(' WScript.Whateve r');

There are also all sorts of other ActiveXObjects which are available
from WSH, such as the FileSystemObjec t <url:

/>

Note that these references are in no way intended to be a complete list
of references, only a sample of the types of references available on the
Web. Other references can be obtained by using Google to search for
something like:

"<object you are interested in> activexobject site:microsoft. com"
