我想要破坏未使用的组织结构图的“四肢”。该图表看起来很好，运行良好。当我打开一个新的时候，我会希望其他肢体崩溃。显然，需要将其限制为与点击元素时父项的距离相等。
提前致谢

答案 0 :(得分：0)
尝试将点击功能修改为：
function click(d) {
root.children.forEach(collapse);
if (d.children) {
d._children = d.children;
d.children = null;
} else {
d.children = d._children;
d._children = null;
}
update(d);
}
基本上它会使所有＆＃34;肢体崩溃＆＃34;之前＆＃34;扩大＆＃34;新的那一个。可能会有一些小错误，但我可以帮助您解决，如果您可以在某处托管您的工作代码，那将更容易。
