- name
The file name.
- lastModifiedDate

- onError
A javascript function that is called if an error occurs. This function takes one parameter, e, which contains information about the error.
Description

Example
var onResult = function(properties) {
if (properties == false) {
alert("File does not exist.");
} else {
alert("File exists!");
}
};
var onError = function(e) {
alert("An error occured!");
};
var filepath = {dialog.object}.phoneGapGetLocalDirURL('private') + 'file.txt';
{dialog.object}.phoneGapFileExistsURL(filepath, onResult, onError);
