Selection API 的 selectionchange 事件在文档上的当前文本选择被改变时触发。

Bubbles	No
Cancelable	No
Target objects	Document
Interface	Event

例子

document.addEventListener("selectionchange", () => {
  console.log(document.getSelection());
});

document.onselectionchange = () => {
  console.log(document.getSelection());
};

继承

selectionchange 事件实现了 Event 接口，因此在此接口上定义的属性和方法都可使用。

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="https://developer.mozilla.org/wiki/zh-CN/docs/Web/API/Event" target="_top"><rect x="1" y="1" width="75" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="38.5" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">Event</text></a></svg></div>

  a:hover text { fill: #0095DD; pointer-events: all;}
