The article submission wizard is messing around with my Code Dowload link, so here is the code in GitHub:. Please ignore the FancyTree project in the source.
That is an article in early progress and will feature here very soon. The user needs to select a folder for backup to another location. JQuery and family have plenty, and one that deserves honourable mention is jQuery FancyTree.
It is, of course, also free and open source. My adaptation of this widget for my folder browser is far from feature perfect and has some drawbacks, but it was very quick and easy to implement, it works, and it allows me to choose a folder, the only real requirement here. This part of the article covers setting up a treeview to show file system data.
At the end of this part, you should be able to create a web page on which people can browse folders. Once the important stuff is out of the way, in Part 2I will show you how to package up all this cool into a new Folder Browser widget, with more features and more reusability.
This is as simple as downloading or installing Bootstrap Treeview and referencing scripts and styles in your view or layout page. The package is available via npm and boweror you can clone or download the whole repo from github. My style references for this project, for the Development environment, look like below. I always try and use non-minified files for development, but there is no non-minified file is this case:.
I also only normally use non-minified scripts for development, except when not available, like here. Place a container and script on your view, ideally a divin which the Treeview must appear:.
The Bootstrap Treeview is very simplistic but tricky. It requires the tree graph data to be ready before you initialize the Treeview.

The fact that we must have the data before initializing the widget means we can do the initialization of the treeview in the done jQuery Ajax method or equivalent :. My simplified node class, TreeNodeis designed to represent a tree node, and is a very small subset of the full specification for a node object, as seen on the home page for the widget, under the heading Data Structure. No other icons are visible on the online examples either, so I chose to omit the icon properties totally, to keep things as small and tidy as possible.
This treeview requires a recursive data structure JSON to represent a whole folder tree as the widget does not support lazy loading, or any Ajax beyond the initial load. It, therefore, needs all the data at once. I find this unnerving, because nesting is rife on a filesystemto who knows what depth, and building and transferring huge JSON documents only hurts performance.
I think the above code is readable, given we know its exact purpose, so no more explanation is required. It seems ideal to have a browsing root, set to a file system folder, that the user cannot browse beyond. They can, using relative paths, but the complexity of checking these paths is beyond the scope of this simple exercise. I have a config setting called BaseDirwhich is the path to where the root of the treeview must begin. The Path. Combine in the controller code helps establish this as the root for the treeview.
If you have followed along this article together with the official documentation for the Bootstrap Treeviewyou should easily be able to put together, if not a real browser widget, at least a page e. Figure 1- Example Folder Browsing that can browse folders. In the second and last part of this article, I will show you how to use your code to build a proper, reusable widget that can be plugged in anywhere you need folder picking or browsing.Use the options in the right panel to change values of corresponding TreeView settings and view result of your changes within the TreeView.
