Javascript 当光标位于内部svg元素上时，d3缩放中断

我已经实现了d3缩放以下简要说明

我正在使用。这是我与d3的第一个项目

我的目标是要有一种平面图，显示场馆内的展位。与教程类似，我从数组中绘制了形状元素。在我的例子中，我将一组展位信息输入到一个元素网格中

缩放功能工作正常，除非光标位于某个矩形的边框或填充上，或者位于元素的文本上。如果光标的点接触这些元素中的任何一个，缩放行为将停止工作

尝试用鼠标滚轮缩放，光标在空白处，而不是触摸形状或文本

我尝试在某个地方安装一个console.log，以查看事件中没有传递的内容，但在找到可以获取事件参数的位置时遇到了困难

非常感谢您的帮助！这是我的密码：

var svg = d3.select("#venue-svg"); // this is my svg element

// the zoom rectangle. from the tutorial: 'The zoom behavior is applied 
// to an invisible rect overlaying the SVG element; this ensures that it 
// receives input, and that the pointer coordinates are not affected by 
// the zoom behavior’s transform.'

svg.append("rect")
  .attr("width", "100%")
  .attr("height", "100%")
  .style("fill", "none")
  .style("pointer-events", "all")
  .call(
    d3
      .zoom()
      .scaleExtent([1 / 2, 4])
      .on("zoom", zoomed)
  );

function zoomed() {
  g.attr("transform", d3.event.transform);
}

// a parent <g> that holds everything else and is targeted
// for the transform (from the tutorial). 
var g = svg.append("g");

// the groups that hold each booth table, associated org name, etc.
var tables = g
  .selectAll("g")
  .data(venueBooths)
  .enter()
  .append("g")
  .attr("transform", function(d) {
    return "translate(" + d.x + " " + d.y + ")";
  });

var tableRects = tables
  .append("rect")
  .attr("stroke", "steelblue")
  .attr("stroke-width", "2px")
  .attr("width", function(d) {
    return d.w;
  })
  .attr("height", function(d) {
    return d.h;
  })
  .attr("fill", "none")
  .attr("fill", function(d) {
    return $.isEmptyObject(d.reservation) ? "none" : "#FF5733";
  })
  .attr("id", function(d) {
    return "table-" + d.id;
  });

tables
  .append("text")
  .text(function(d) {
    return "Booth " + d.id;
  })
  .attr("dx", 5)
  .attr("dy", 60)
  .attr("font-size", "8px");

tables
  .append("text")
  .text(function(d) {
    return d.reservation.orgName ? d.reservation.orgName : "Available";
  })
  .attr("dy", 15)
  .attr("dx", 5)
  .attr("font-size", "9px")
  .attr("font-weight", "bold");

最后尝试创建rect，使DOM如下所示：

<svg>
    <g></g>
    <rect></rect>
</svg>

谢谢，下面的valangar给出了一个有效的解决方案，并将更改推送到了我链接的演示中。我更新了帖子以保存并删除了链接。
