Question

我有一个SVG图像，我放置了更多的图像（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d3js，但它无法正常工作。

 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);
        })

以下是SVG图像示例
