when user select file from dialog, isZipFile return false

[misaz]

Good morning,
I make web application. I have small problem. User select zip file from your computer and i have blob from it. My code for load zip is:

var readerWorker = new FileReader()
var fileWorker = fileForOpen.files[0]
readerWorker.onload = function (e) {
      var text = e.target.result
      text = text.toString().substring(41)
      var zip = new JSUnzip(text)
      var isZip = zip.isZipFile()
      if (isZip) {
            zip.readEntries()
            for (var file in zip.entries) {
                  var withoutCompression
                  if (file.compressionMethod === 0) {
                        withoutCompression = file.data
                  } else if (file.compressionMethod === 8) {
                        withoutCompression = JSInflate.inflate(file.data)
                  }
            }
      }
}
readerWorker.readAsDataURL(fileWorker)

In the variable text is for example:

UEsDBAoAAAAAALKDfkLEb0P5GwAAABsAAAAIAAAAZGF0YS50eHRhYWFhYQpiYmJiCjI1CkdyYWZpawpjY2NjY2NQSwMECgAAAAAAwoN+QnOXrZQ4AAAAOAAAAAgAAABmb3RvLmpwZ3WrWopmoHv4In22rHuuEdJRjg3YQUABQCAAgAAAAD/3gAsAAAAAAUABQAAAgiMD5FnqwpSAQA4AUEsBAhQACgAAAAAAsoN+QsRvQ/kbAAAAGwAAAAgAAAAAAAAAAAAAAAAAAAAAAGRhdGEudHh0UEsBAhQACgAAAAAAwoN+QnOXrZQ4AAAAOAAAAAgAAAAAAAAAAAAAAAAAQQAAAGZvdG8uanBnUEsFBgAAAAACAAIAbAAAAJ8AAAAAAA==

If I debug it, I see in variable isZip value false. Why?

Hey!

I just deprecated this project. I was looking into fixing bugs and updating it, but I found a much better alternative that didn't exist when I created this project. Check it out :)
