doDownload() Method
As you previously saw, downloading a file is implemented in the downloadFile.jsp file, so the
question is, how do we get the user there? The answer is found in the doDownload() method:
this.doDownload = function(inSelectedDirectory, inSelectedItem) {
// Only do something if both a directory and an item in the grid are
// selected.
if (inSelectedDirectory == null || inSelectedItem == null ||
inSelectedDirectory == "" || inSelectedItem == "") {
alert("Please select a file to download");
return;
}
// Make sure the selected item is a file.
var itemType = fileGrid.cells(inSelectedItem, 2).getValue();
if (itemType == "Directory") {
alert("Sorry, only files can be downloaded");
return;
}
// Get the name and path of the selected file.
var directoryPath = directoryTree.getUserData(inSelectedDirectory, "path");
var fileName = fileGrid.getUserData(inSelectedItem, "name");
