我想在svg文件中添加一個圓形元素。我通過d3.xml導入文件並在svg中添加了圓圈元素,但圓圈沒有顯示在svg圖片上。當我試圖打印svgNode時,我能夠查看圓形元素,但它不會顯示在屏幕上?無法更改現有的svg文件
d3.xml("img/myImage.svg", function(error, documentFragment) {
if (error) {console.log(error); return;}
var svgNode = documentFragment
.getElementsByTagName("svg").contentDocument;
d3.select(svgNode)
.selectAll("g")
.append("circle")
.attr("cx", 500)
.attr("cy", 25)
.attr("r", 150)
.style("fill", "purple");
console.log(svgNode);
?
MyImage.svg文件看起來像這樣

附加圓圈後,您如何顯示SVG? – Mark
