更改svg图像的颜色

Question

我有一个SVG图像，其中放置了更多图像（它们也是svg图形）。我需要在鼠标悬停时更改颜色。

现在我正在尝试以下与d3js但它不工作。

graph 
     .selectAll('g') 
     .data(Operators) 
     .enter() 
     .append('g') 
     .selectAll('image') 
     .data(function (d) { 
      //console.log('image d', d); 
      return d; 
     }) 
     .enter() 
     .append('image') 
     .attr('id', function (d) { 
      return d.name; 
     }) 
     .attr('x', function (d) { 
      return d.x; 
     }) 
     .attr('y', function (d) { 
      return d.y ; 
     }) 
     .attr('width', function (d) { 
      return d.width; 
     }) 
     .attr('height', function (d) { 
      return d.height; 
     }) 
     .attr("xlink:href", function (d) { 
      return base_url + "/assets/svg/" + d.src; 
     }) 
     .style('fill', function (d) { 
      //return d.hoverColor; 
     }) 
     .on('mouseover', function (d) { 
      var img = d3.select(this); 
      console.log('hoverColor: ', d.hoverColor); 
      img.style('fill', d.hoverColor); 
     }) 

下面是一个简单SVG图像

谁能帮助我？

Answer 1

用简单的CSS：

添加到您的路径元素的类名像class="svgimg"

，然后在CSS

svg:hover .svgimg { fill: darkslateblue; }
