如何使所有svg元素适合div，不溢出和隐藏元素？

标签： javascript html d3.js svg

我的页面中有svg图表，我使用的是d3。我无法获取svg中的元素（圆圈）以适应html，换句话说，我不希望元素溢出。我尝试更改viewport和viewBox属性但是没有用。

这就是发生的事情 Pictrue of the problem

svg属性的定义

     var myChart = d3.select('#bubbles')
    .append("div")
    .style("transition", "all", "1s")
    .classed("svg-container", true)
  .append('svg')
    .attr("id", "svgId")
    .attr("viewport", "0 0 300 300")
    .attr("viewBox", "2 2 400")
    .attr("width", "80%")
    .attr("height", getBubblesHight() + "px")
    .classed("svg-content-responsive", true)
    .style("float","right")


  var link = myChart.selectAll('line')
    .data(links).enter().append('line')
    .attr('stroke', palette.gray)
    .attr('strokewidth', '1');

  var node = myChart.selectAll('circle')
    .data(nodes).enter()
    .append('g')
    .call(force.drag);

  node.append('circle')

  .attr('cx', function(d) {
      return d.x;
    })
    .attr('cy', function(d) {
      return d.y;
    })
    .attr('r', function(d, i) {
      console.log(d.value);
      if (d.group) {
        return 38;
      } else  if(d.main){
        return 68;
      }else{
        return 50;

      }
    })
    .style("fill", function(d,i){
                  if(d.main&&!d.group){
                    return    "#f5f5f5";
                  }else {
                    return "#dcdcdc";
                  }
              })

  .attr('strokewidth', function(d, i) {
      if (i > 0) {
        return '0';
      } else {
        return '0';
      }
    })
    .attr("class", function(d) {
      if (d.project) {

      } else {
        return "bubble";
      }
    })
    .attr("id", function(d, i) {
      return d.id;

    })

  .attr('stroke', function(d, i) {
    if (i > 0) {
      return '';
    } else {
      return '';
    }
  })

  ;

  force.on('tick', function(e) {
    node.attr('transform', function(d, i) {
      return 'translate(' + d.x + ',' + d.y + ')'
    })

    link
      .attr('x1', function(d) {
        return d.source.x;
      })
      .attr('y1', function(d) {
        return d.source.y;
      })
      .attr('x2', function(d) {
        return d.target.x;
      })
      .attr('y2', function(d) {
        return d.target.y;
      })
  });
      node.append('text')
    .text(function(d) {
      return d.name;
    })
    .attr("class", "text")
    .attr('font-family', 'PT Sans', 'sans-serif')
    .attr('fill', "#3d3d3d")
    .attr('text-anchor', function(d, i) {
      return 'middle';
    })
    .attr('font-size', function(d, i) {
      if (i > 0) {
        return '.8em';
      } else {
        return '.8em';
      }
    })

  force.start();

由于你没有粘贴你的d3.layout.force()（假设这是v3.x），很难说什么，但我猜你错过了{ {1}}，或者设置不正确。
