我有 SVG 多边形，对于某些多边形，我使用图案作为填充。但我想要那个图案的背景颜色。就像背景颜色上的图案。 

var pattern = me.canvas.append('defs')
    .append('pattern')
    .attr('id', 'diagonalHatch')
    .attr('patternUnits', 'userSpaceOnUse')
    .attr('width', 4)
    .attr('height', 4)
    .append('path')
    .attr('d', 'M-1,1 l2,-2 M0,4 l4,-4 M3,5 l2,-2')
    .attr('stroke', '#010101')
    .attr('stroke-width', 1)
    .attr("opacity",0.5);


var polyObj = polygonLayer.append("polygon")
        .attr('stroke','black')
        .attr('stroke-width','2')
        .style('fill','url(#diagonalHatch)');

我有这个fiddle .我想要这个图案背后的颜色。

请帮忙。

最佳答案

正如我在评论中提到的，一种方法是在 pattern 中(在 path 之前)添加一个 4x4 rect 并且然后给 rect 所需的填充。

<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.11/d3.min.js"></script>

<head>
  <div id='myDiv'></div>

  <script type="text/javascript">
    var canvas = d3.select('#myDiv')
      .append('svg')
      .attr('width', '400px')
      .attr('height', '400px');

    canvas.append('defs')
      .append('pattern')
      .attr('id', 'diagonalHatch')
      .attr('patternUnits', 'userSpaceOnUse')
      .attr('width', 4)
      .attr('height', 4)
      .append('rect')
      .attr('width', 4)
      .attr('height', 4)
      .attr('x', 0)
      .attr('x', 0)
      .attr('fill', 'blue');

    d3.select('#myDiv svg pattern#diagonalHatch').append('path')
      .attr('d', 'M-1,1 l2,-2 M0,4 l4,-4 M3,5 l2,-2')
      .attr('stroke', '#010101')
      .attr('stroke-width', 1)
      .attr("opacity", 0.5);



    var polygon = canvas.append('polygon')
      .attr('fill', 'none').attr('points', '282.0000915527344,104,280.0001220703125,165.00009155273438,349,174.99998474121094,345.00006103515625,105.99999237060547,282.0000915527344,104')
      .attr('stroke', 'black')
      .attr('stroke-width', '2')
      .style('fill', 'url(#diagonalHatch)')
  </script>
</head>
