Add svg on exists path-CodePudding

I had an exsits path that represent line with arrow:

<path {...lineProps} id={id} />

it looks like:

is there a chance to add the next svg in the middle of the current link:

it looks like:

eventually it should look like:

CodePudding user response：

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);
