Interactive jQuery Menu

A few days ago I was asked to update the layout of the website for a store I used to work at.

I thought this was a good chance to get to know jQuery animations, so I put together a bunch of stock images as background, edited pictures of frames and put some text in the frames for the icons.

I worked with artboards in Affinity Designer so I could export multiple images to different files, I also worked with groups and a transparent background so I could make .png files of the frames and put them on top of the background images.

That way I used the background-image css property, with display set to block and could superimpose a png with transparency over another image.

With jQuery I selected all images, where each image has a class “RT” and I used the reserved word this to select the particular instance for mouseover and mouseleave events.

With this I managed to make a fun little menu where the frame with the text grows and shrinks according to mouse-events.

The result can be seen here.

A tiny online vector graphics application.

As a small project to familiarise myself with JavaScript, jQuery and SVG I started working on a small vector graphics app using the SVG.js library.

At first I was thinking of manipulating SVG-text directly as I had done with my desktop Java applications, but since I found that simply appending or updating the inner html of divs didn’t refresh the SVG canvas and other annoying things I found it was smarter to just use a simple JavaScript library for this.

In addition to learning a lot of jQuery and JavaScript, especially understanding the specifics of JavaScripts idiosyncratic approach to OOP, I learned a bit about which existing libraries there are and how to use them. For this small application, SVG.js did nicely, but I also learned about a larger library called Raphaël, and an interesting little script called Flowtype, that automagically resizes the font size in relation to the window size.

I put the source code of my little application on GitHub here.

Up to now I’ve only managed to do the most basic rectilinear polygons, with the foundations set for snapping and I’m planning to create a simple colour-picker functionality for the stroke, fill and opacity.

The hotkeys are:

cmd+z – UNDO (mac)

ctrl+z – UNDO (windows, linux)

D – Delete the last polygon.

S – Show data on the selected polygon.

Polygons are created by closing the path.

This is done by creating a line where the end coordinate is the same as the first coordinate of the polygon.
