I loaded a directory using file input and webkitdirectory as mentioned below.
<input id="file_input" type="file" webkitdirectory directory />
After directory selected I can read file size and other information. My question is how to read this directory using DirectoryReader interface.
I tried with below code, but not success. results.length becomes zero. Am I missing anything?
window.requestFileSystem(TEMPORARY, 1024*1024 /*1MB*/, function(fs) {
var dirReader = fs.root.createReader();
var entries = [];
// Call the reader.readEntries() until no more results are returned.
var readEntries = function() {
dirReader.readEntries(function(results) {
// If no more results are returned, we're done.
if (!results.length) {
// Sort list by name of entry.
entries.sort(function(a, b) {
return a.name < b.name ? -1 :
b.name < a.name ? 1 : 0;
});
// listResults(entries); // Render the list.
} else {
// Add in these results to the current list.
entries = entries.concat(toArray(results));
readEntries();
}
}, errorHandler);
};
readEntries(); // Start reading the directory.
}, errorHandler);
Any help is appreciated.
To read the content of a directory :
fs.root.getDirectory('Documents', {}, function(dirEntry){
var dirReader = dirEntry.createReader();
dirReader.readEntries(function(entries) {
for(var i = 0; i < entries.length; i++) {
var entry = entries[i];
if (entry.isDirectory){
console.log('Directory: ' + entry.fullPath);
}
else if (entry.isFile){
console.log('File: ' + entry.fullPath);
}
}
}, errorHandler);
}, errorHandler);
In the code above, the isDirectory and isFile properties are used in order to obtain a different output for directories and files, respectively. Additionally, we use the fullPath property in order to get the full path of the entry, instead of its name only.
