QUESTION
I have SVG icons of some elements. These elements are for example road signals on the level crossing. If a road signal is shining RED light, I change the appropriate SVG element's fill to red.
Now I have these elements in a menu, and I want each of them to have it's icon, but also that this icon represents its lamp state. So when the lamp state changes, the icon at the appropriate element also changes.
I did this before in Java (GWT) and I did it by loading the icon into a variable in a helper class (SvgHelper) and then anytime I wanted to display icon of particular element anywhere, I called svgHelper.getIcon(element) and it modified the svg, that it has stored in a variable, (in the background) and then returned me new cloned SVGImage that I could the put anywhere. So I only had one icon, changed its state, cloned it and returned.
Now when I want to do it in javascript, it seems, that to work with the SVG in any way, it has to be in the DOM first.
Is there a way to work with the SVG "in the background" so that it is not in the DOM? Because I would rather change multiple SVG properties and once finished then put the SVG in the DOM. Also I target the elements by ID and there can be multiple of those icons on a single page, so the IDs would collide.
I tried using svg.js and import my svg from string, but from what I understood the library actually requires some div to work in, so it adds it to the DOM.
In java I was doing it using this library and since it is in the end compiled to JS, there should be a way to do it.
...ANSWER
Answered 2019-Sep-24 at 08:38Since even the GWT library adds the SVG to the DOM, I ended up doing just that. So I have some object which I have in a DOM somewhere outside of the screen, target the element by ID, change its properties. Onec the SVG is ready, I put it in its destination using vuejs's v-html directive.
