如何在SVG中制作“弯曲矩形”?

Jam*_*ond 2 html css svg

我有一个正在处理的项目,要求我进行圆形导航,并使用按钮,如下图所示。我可以绘制简单的形状并足够好地按照教程进行操作,但是我不知道如何绘制带有弯曲形状的这些条,如下图所示。

我提供了一个剪切路径示例,但是我认为SVG是我需要做的。

的HTML

的CSS

.button {
    background: radial-gradient(circle at 50% 160%,transparent 45%,red 44.5%,red 85%,transparent 85%);
        -webkit-clip-path: polygon(5% 0, 100% 0, 65% 90%, 35% 90%);
        clip-path: polygon(20% 0, 80% 0, 65% 90%, 35% 90%);

首先,我创建一个段(路径)。然后我通过旋转使用它来重用它。

const SVG_NS = 'http://www.w3.org/2000/svg';
const SVG_XLINK = "http://www.w3.org/1999/xlink";
const deg = 180 / Math.PI;
let R = 50;// the outer radius
let r = 35;// the inner radius
let A = 2*Math.PI/7;// the angle for the segment + space
let a = 2*A/3; // the angle for the segment


let path = document.createElementNS(SVG_NS, 'path');
let p1 = {x:0,y:-R}
let p2 = {
  x : R*Math.cos(a - Math.PI/2),
  y : R*Math.sin(a - Math.PI/2)
}
let p3 = {
  x : r*Math.cos(a - Math.PI/2),
  y : r*Math.sin(a - Math.PI/2)
}
let p4 = {
  x : 0,
  y : -r
}
let d = `M${p1.x},${p1.y}
         A${R},${R} 0 0,1,${p2.x},${p2.y}
         L${p3.x},${p3.y}
         A${r},${r} 0 0,0,${p4.x},${p4.y}
         L${p1.x},${p1.y}Z
`;
path.setAttributeNS(null, "d", d);
path.setAttributeNS(null, "id", "arc");
defs.appendChild(path);




for(let i = 0; i < 7; i++){
 let use = document.createElementNS(SVG_NS, 'use');
  use.setAttributeNS(SVG_XLINK, "xlink:href", "#arc")
  use.setAttributeNS(null, "fill", "gold");
  use.setAttributeNS(null, "transform", `rotate(${i*A*deg})`);
  svg.appendChild(use);

或更简单:这次我正在使用stroke-dasharray,我正在计算笔触和间隙的大小

const SVG_NS = 'http://www.w3.org/2000/svg';
let R = 40;

let perimeter = 2*Math.PI*R
let dash = .7*perimeter/7;
let gap = .3*perimeter/7;


let dasharray = document.createElementNS(SVG_NS, 'circle');
dasharray.setAttributeNS(null, "r", R);
dasharray.setAttributeNS(null, "stroke-dasharray", `${dash}, ${gap}`);

svg.appendChild(dasharray);
