如何在svg圈内添加链接

Question

我用svg画了一个圆圈.这个圆圈有悬停效果.我想在圆圈内添加一个链接,并在链接文本中添加颜色以及悬停效果.

svg#circle {
  height: 250px;
  width: 250px;
}

circle {
  stroke-dasharray: 700;
  stroke-dashoffset: 700;
  stroke-linecap: butt;
  -webkit-transition: all 2s ease-out;
  -moz-transition: all 2s ease-out;
  -ms-transition: all 2s ease-out;
  -o-transition: all 2s ease-out;
  transition: all 2s ease-out;
}

circle:hover {
  fill: pink;
  stroke-dashoffset: 0;
  stroke-dasharray: 700;
  stroke-width: 10;
}

<svg id="circle">
        <circle cx="125" cy="125" r="100" stroke="darkblue" stroke-width="3"     fill="green" />
     </svg>

Answer 1

您需要添加text包含在锚链接中的元素.

请注意,位于该text顶部的元素circle会阻止该圆圈上的悬停操作.所以,我把整个事情包裹在一个g组中,然后将悬停捕获放在那个上面.

svg#circle {
  height: 250px;
  width: 250px;
}
g circle {
  stroke-dasharray: 700;
  stroke-dashoffset: 700;
  stroke-linecap: butt;
  -webkit-transition: all 2s ease-out;
  -moz-transition: all 2s ease-out;
  -ms-transition: all 2s ease-out;
  -o-transition: all 2s ease-out;
  transition: all 2s ease-out;
}
g:hover circle {
  fill: pink;
  stroke-dashoffset: 0;
  stroke-dasharray: 700;
  stroke-width: 10;
}
text {
  fill: pink;
  font-size: 24px;
}
a:hover text {
  fill: blue;
}

<svg id="circle">
   <g>
  <circle cx="125" cy="125" r="100" stroke="darkblue" stroke-width="3" fill="green" />
  <a xlink:href="https://www.google.co.uk/" target="_top">
    <text x="50%" y="50%" style="text-anchor: middle">google</text>
  </a>
     </g>
</svg>

Answer 2

我认为这会奏效:

<svg id="circle">
  <a xlink:href="https://www.google.com" style="cursor: pointer" target="_blank">
    <circle  cx="125" cy="70" r="60" stroke="darkblue" stroke-width="3" fill="green" />
  </a>
</svg>

编辑:动态添加到SVG的链接Circle.

function addAnchor(){
  var dummyElement = document.createElement("div");
  dummyElement.innerHTML = '<a xlink:href="https://www.google.com" style="cursor: pointer" target="_blank"></a>';
  
  var htmlAnchorElement = dummyElement.querySelector("a");

  var circleSVG = document.getElementById("circle");

  htmlAnchorElement.innerHTML = circleSVG.innerHTML;

  circleSVG.innerHTML = dummyElement.innerHTML;
  
}

<svg id="circle">
    <circle  cx="125" cy="70" r="60" stroke="darkblue" stroke-width="3" fill="green" />
</svg>

<button onclick="addAnchor()">Add Anchor</button>
