How do you store a file locally using Apache Cordova 3.4.0

Question

I am having a problem storing a file locally on an iOS (or android) device using apache cordova\'s \"file\" plugin. The problem I believe is setting the path properly.

Answer 1

So far I have only tested this on Android, but I believe it should work as-is, or with little modification on IOS:

var url = 'example.com/foo'

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSystem){
    fileSystem.root.getFile('foo_file', {create: true, exclusive: false},
        function(file_entry){
            var ft = new FileTransfer()
            ft.download(url, file_entry.toURL(), function(fe){
                fe.file(function(f){
                    reader = new FileReader()
                    reader.onloadend = function(ev){
                        console.log('READ!', ev.target.result)
                    }
                    reader.readAsText(f)
                })
            })
        }
    )
})

Note that I also needed the contents of the file, so the bit at the end may be omitted if you don't need the contents at the time of downloading.

Also note that there is a far simpler method using window.saveAs but it's only available in Android 4.4.
