Have a look at the element and it’s four attributes. You define your graphic in one place and reference it in another. We’ve seen this before with patterns, symbols, and groups. The id is then referenced by the rectangles’s fill property. Some of the style for the stroked circle is in the CSS.The example defines a linear gradient inside tags and gives the gradient an id of linear. NewStroke.addEventListener("click", animateClip) Let newStroke = document.createElementNS(svgns, "circle") Why? I’m adding a 4 unit stroke so I subtract the 2 units from the radius since strokes are center aligned. This one has the same center as the base-color circle, but the radius is a bit smaller.
We need an empty target to click so we create a second circle in our loop. The only change is they get appended to a group, instead of the root SVG. The base circles with color are created the same way as the last demo so I won’t cover that again. Finally, we’ll add a rectangle for each base circle and add it to the clipPath. I’ll also add a second transparent circle that will not be clipped and has a stroke. We append the base circles to the baseGroup, which is clipped by the clipPath group. We then add another loop around that loop for the rows.
Our old loop from the last section will become the columns. This will also be used for adding numbers in the next section.Ĭonst svgHeight = height * rows Loop around your loop I’m using a counter variable for the color array. We’ll change the math a bit to correctly size the SVG. Instead of a simple number of targets, we’ll use rows and columns variables. A few minor changes and we’ll be good to go. Okay, what if we want something like a grid? No problem.

After that, it’s the same rectangle creation code from above except it’s now in a loop. In this case, I’ve set the width to 90vw in the CSS. If you applied the width & height as an inline style, the SVG would no longer be responsive. set attributes of new rectangleĪttr: wrapper for the SVG width, height and viewBox. Using the core GreenSock tools (GSAP) and the attrPlugin (short for attribute plugin), we can accomplish the same thing from above in a more concise syntax. This is what I’ll be using for the rest of this article and all the demos. You can use the setAttribute() method I showed above (if you like), but I animate everything with GSAP so I’ll be taking advantage of those tools and using the set() method to style my elements. Pretty easy, but not too exciting yet, is it? Well, we have to learn to walk before we can run. targeting the svg itselfĬonst svg = document.querySelector("svg") ĭynamic SVG Element Creation #1 by Craig Roblewsky ( CodePen. To append the rectangle to the SVG, you target the SVG and use the appendChild() method. To style the rectangle, you can use the setAttribute() method. Let newRect = document.createElementNS(svgns, "rect") Īgain, nothing showing yet as it has no style and has not been appended to the SVG. The new code looks like this: // variable for the namespace We also don’t want to keep typing out the SVG namespace so we assign that to a variable. The code above won’t show anything as we haven’t styled the rectangle or added it to the SVG document yet. Let newRect = document.createElementNS("", "rect") Creating a rectangle looks like this: // make a simple rectangle We won’t worry about the optional options parameter. That just says, “Hey, we’re creating SVG elements here.” The qualified name is the element we’re creating - rect, text, circle etc. The syntax from the MDN docs reads: var element = document.createElementNS(namespaceURI, qualifiedName) Ĭool, but what does that mean? The namespace is simply “”. To create SVG elements, we need to use the createElementNS() method. I also used a background rectangle so we can see what we’re doing. I’ve manually added it, but you can create and add it via JavaScript as well. Starter infoĪll of the following demos have an empty SVG element in the HTML. In this tutorial, we’ll take a look at creating dynamic SVG elements. In those cases, it is often faster, easier and more flexible to let JavaScript do the heavy lifting for you. But what if you want a whole bunch of repeating shapes? That can be a bit cumbersome. You’re probably used to creating your SVG masterpieces in your vector software.
