Animate SVG with Javascript - javascript

I'm currently testing different options to animate SVG Files directly in the .svg File. RIght now I'm testing animation with includet javascript. The Problem is, i don't get a proper rotation around the origin working.
My Code is currently looking like that:

So what am I missing, or does there a better solution exist? Maybe it is possible to include jquery in the svg File?
Thanks in advance


Maybe you should stick to normal SVG tools and not over complicate things for something as trivial as a rotation.
It wasn't clear to me what you want to spin, so I made them both spin:

Here you go, a version with scripting, impractical, but since you wanted it...
dz.setAttribute("transform", "rotate(" + zpos + " 32 32)");

Notes:
I couldn't make it work with changing the style property. Not sure why.
You don't need to reset from 359 to 0. Degrees are anyway computed mod 360.

it looks like:
eventually it should look like:

As #AKX commented you need to find the point in the middle of the path. You can do it using the getTotalLength and getPointAtLength methods.
As for the tag you can put it inside a symbol and use the symbol with <use>. The use element can take an x and y attributes, the x and y of the point in the middle of the path. In order to center the use element around the point you need also to translate the use element backward half width and height
//the path length
let l = thePath.getTotalLength();
//the point in the middle of the path
let p = thePath.getPointAtLength(l/2);
//set the x andy attributes in the middle of the path
theUse.setAttribute("x", p.x);
theUse.setAttribute("y", p.y);

How can I make a toggle to toggle the visibility of an inline SVG?

I'm making a website where you can create your own character in order to learn more about SVGs. I want the user to be able to select different poses.
I was wondering how I could toggle the visibility of an SVG on the website to make one disappear and another appear.
Here is my SVG code:

The SVG is just a sample right now before I make the actual assets.

svg path fill animation

The general idea is this: you draw the path you clip it as you need and next you animate the stroke-dashoffset of the clipped path. You make sure that the animation for the next path begins after the previous one ends: begin="a.end + .5s".
However in this case you will need to rewrite the paths. For example in the case of the lace I would use 2 paths and 2 different clip-paths or even 3. Otherwise you get an unaesthetic bleeding effect where the path overlaps.

Your semicircle is drawn using a double path see image below
Therefore, you can animate figure drawing only with the help of filter ormask
I suggest using the technique of drawing a figure from the top point to a semicircle, by changing the 'stroke-dasharray' of the middle line of the figure.
The middle line turned out - a circle with the center of (70.70) and a radius of 50
Next, set stroke-width ="20" and stroke-dasharray = "157 157" to get half the circle
Turn the semicircle counterclockwise 90 degrees so that its beginning is at the top

SVG: Trigger a click event on animateTransform after clicking a button

I would like to have my svg animation run when clicking an html button. I thought I could make that work by setting begin="click in my animateTransform and then trigger a click event on the animateTransform (or the svg element containing the animateTransform, I tried both) using js.
Any advice would be a great help.
var needle = $('#needle'),
tape = $('#tape'),
btn = $('#muhBtn');
btn.on('click', function() {
needle.click();
tape.click();
});
#tape {
fill: #ED1C24;

#needle {

If you want to start the animations just do it directly via javascript and the beginElement method, no need for all that click event rigmarole. Note that I've changed the begin on the animation from click to indefinite to make it clearer what's happening.
var needle = $('#animateNeedle'),
tape = $('#animateTape');
btn = $('#muhBtn');
btn.on('click', function(){
needle[0].beginElement();
tape[0].beginElement();
});
