(JavaScript) List Files/Directories in Zip by Index
Demonstrates how to iterate over the files and directories in a zip archive by index.Note: This example requires Chilkat v11.0.0 or greater.
var success = false;
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var zip = new CkZip();
success = zip.OpenZip("qa_data/zips/sample.zip");
if (success == false) {
console.log(zip.LastErrorText);
return;
}
var numEntries = zip.NumEntries;
var entry = new CkZipEntry();
var i = 0;
while (i < numEntries) {
zip.EntryAt(i,entry);
// Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries.
// However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
// An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file.
// It usually has a directory name with a trailing slash (/) and zero-length content.
if (entry.IsDirectory) {
console.log(i + ": " + entry.FileName + " (directory)");
}
else {
console.log(i + ": " + entry.FileName);
}
i = i+1;
}
// Sample output:
// 0: aaa/ (directory)
// 1: aaa/pigs.json
// 2: bbb/ (directory)
// 3: bbb/base64Cert.txt
// 4: bbb/sub1/ (directory)
// 5: bbb/sub1/brasil_cert.pem
// 6: bbb/sub2/ (directory)
// 7: bbb/sub2/penguins.gif
// 8: bbb/sub2/starfish.jpg
// 9: hamlet.xml
// 10: hello.pdf
zip.CloseZip();
