Description

Excuse me if I did something stupid - I'm new to Cordova and JS.

I thought that calling write() after checking readyState != WRITING would work.

function writeQueue(c) {
        while ( !(logWriter.readyState === FileWriter.WRITING) ) {
            var msg = logQueue.dequeue();
            if (!msg) {
                return;
            }

            var blob = new Blob([msg+c], { type: 'text/plain' });
            logWriter.write(blob);
        }
    }
}

But I get:
0 277161 log log writer: cdvfile://localhost/files/bala.log
1 277199 log log writer: onwriteend
2 283616 log log writer: onwriteend
3 283629 log log writer: onwriteend
4 283651 error Uncaught #<FileError>, http://192.168.1.200:8100/plugins/cordova-plugin-file/www/FileWriter.js, Line: 130

Line 130 is:

    // Throw an exception if we are already writing a file
    if (this.readyState === FileWriter.WRITING) {
        throw new FileError(FileError.INVALID_STATE_ERR);
    }

How can readyState change to WRITING ?
