javascript 移动后 SVG 路径保持不变

Question

我的 SVG 中有一个矩形，我有一个像飞机一样的图形，我想使用蒙版并将其移动到随机轨道上。我正在寻找解决方案。

编辑：我想得到一个 javascript ，它使黑色路径像 SVG 中的蒙版一样。想移动并复制元素。

这是我的svg，我想移动飞机并在移动后复制：

<svg id="Layer_1" xmlns="http://www.w3.org/2000/svg" xml:space="preserve" height="500px" viewBox="0 0 500 500" width="500px" version="1.1" y="0px" x="0px" xmlns:xlink="http://www.w3.org/1999/xlink" enable-background="new 0 0 500 500">

我不确定我是否完全理解您想要什么。但这里有一个小演示，希望至少能帮助您入门。

// Get references to the various elements in the SVG
var svg = document.getElementById("Layer_1");
var blackpath = svg.getElementById("blackpath");
var redplane = svg.getElementById("redplane");

// Add an event listener to the SVG that captures mouse move events
svg.addEventListener("mousemove", function(evt) {
  // Convert the mouse position from screen coords to SVG coords.
  var pt = svg.createSVGPoint();
  pt.x = evt.clientX;
  pt.y = evt.clientY;
  pt = pt.matrixTransform(svg.getScreenCTM().inverse());

  // Move the red plane to the mouse mosition
  redplane.setAttribute("x", pt.x);
  redplane.setAttribute("y", pt.y);

  // Create a <use> element to add a cloned "copy" of the plane to the "blackpath" group.
  var useElement = document.createElementNS("http://www.w3.org/2000/svg", "use");
  useElement.setAttributeNS("http://www.w3.org/1999/xlink", "href", "#plane");
  // Position the clone at the mouse coords
  useElement.setAttribute("x", pt.x);
  useElement.setAttribute("y", pt.y);
  // Add it to the blackpath group
  blackpath.appendChild(useElement);
});

<svg id="Layer_1" xmlns="http://www.w3.org/2000/svg" height="500px" viewBox="0 0 500 500" width="500px" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink">
