Difficulty reading file into variable.

[tjlahr10]

I'm having trouble reading a file into a string and can't figure out why.

var myFile = new File( '/path/to/my/file.xml' );

var myFileString = myFile.read();

alert( myFileString.length ); // displays 0

Does anybody know what could be going on here? It seems like such a simple operation.

Thanks.

I think I figured it out.

The file has be opened first with myFile.open('r');

Yes you are right.

Here is Javascript reference for file.Open()

fileObj.open (mode[,type][,creator])

mode A string indicating the read/write mode. One of:

➤ r: (read) Opens for reading. If the file does not exist or cannot be found, the call fails.

➤ w: (write) Opens a file for writing. If the file exists, its contents are destroyed. If

the file does not exist, creates a new, empty file.

➤ e: (edit) Opens an existing file for reading and writing.

➤ a: (append) Opens the file in Append mode, and moves the current position to the end of the file.

type Optional. In Mac OS, the type of a newly created file, a 4-character string. Ignored in Windows and UNIX.

creator Optional. In Mac OS, the creator of a newly created file, a 4-character string. Ignored in Windows and UNIX.

and you must close a file after opening it.

var myFile = new File( '/path/to/my/file.xml' );
myFile.open("r");//for open real only
var myFileString = myFile.read();
myFile.close();
alert( myFileString.length);
