The File I/O API 27
Arguments
fileURL, text, {mode}
■ The fileURL argument, which is expressed as a file:// URL, is the file to which you are
writing.
■ The text argument is the string to be written.
■ The mode argument, if it is supplied, must be "append". If this argument is omitted, the
contents of the file are overwritten by the string.
Returns
A Boolean value: true if the string is successfully written to the file; false otherwise.
Example
The following code attempts to write the string "xxx" to the mydata.txt file and displays an
alert message if the write operation succeeds. It then tries to append the string
"aaa" to the
file and displays a second alert if the write succeeds. After executing this script, the mydata.txt
file contains the text
xxxaaa and nothing else.
var fileURL = "file:///c|/temp/mydata.txt";
if (DWfile.write(fileURL, "xxx")){
alert("Wrote xxx to " + fileURL);
}
if (DWfile.write(fileURL, "aaa", "append")){
alert("Appended aaa to " + fileURL);
}
