Please use the FileTransfer API from Phonegap or CoreDova. Here is the sample code from the same source:

var fileTransfer = new FileTransfer();
var uri = encodeURI("http://some.server.com/download.php");

fileTransfer.download(
    uri,
    filePath,
    function(entry) {
        console.log("download complete: " + entry.fullPath);
    },
    function(error) {
        console.log("download error source " + error.source);
        console.log("download error target " + error.target);
        console.log("upload error code" + error.code);
    }
);

To save the file on SDCard use FileWriter

function gotFileWriter(writer) {
    writer.onwriteend = function(evt) {
        console.log("contents of file now 'some sample text'");
        writer.truncate(11);  
        writer.onwriteend = function(evt) {
            console.log("contents of file now 'some sample'");
            writer.seek(4);
            writer.write(" different text");
            writer.onwriteend = function(evt){
                console.log("contents of file now 'some different text'");
            }
        };
    };
    writer.write("some sample text");
}

function fail(error) {
    console.log(error.code);
}
