D3 размыть/уменьшить непрозрачность несвязанных ссылок при перетаскивании определенного узла

Я пытаюсь размыть / понизить непрозрачность несвязанных ссылок при перетаскивании определенного узла. Таким образом, при перетаскивании нужно выделять только связанные ссылки и узлы и размывать те, которые не относятся к перетаскиваемому узлу. Он работает, если он находится вне функции перетаскивания, но он несовместим, когда я держу его внутри него. Просто хаотично мигает. Это должно происходить в перетаскивании?

Ответ принят как подходящий

dragged вызывается во время перетаскивания, поэтому имеет смысл обновлять непрозрачность ссылки в dragstarted и dragend, т.е. минимальное количество раз.

Например. в dragstarted запустите тест на то, подключены ли ссылки, и соответствующим образом обновите непрозрачность (например, 1 для подключенных ссылок, 0,1 для несвязанных ссылок):

const dragstarted = (event) => {
  if (!event.active) simulation.alphaTarget(0.3).restart();
  event.subject.fx = event.subject.x;
  event.subject.fy = event.subject.y;

  // update link opacity to 0.1 for non-connected nodes
  link.each(function(d) {
    const test = d.source.id === event.subject.id || d.target.id === event.subject.id;
    d3.select(this).attr("opacity", test ? 1 : 0.1);
  });
}

Затем в dragended вы можете вернуть ссылки к исходному состоянию непрозрачности:

const dragended = (event) => {
  if (!event.active) {
    simulation.alphaTarget(0)
  };
  event.subject.fx = null;
  event.subject.fy = null;

  // reset link opacity to 1
  link.attr("opacity", 1);
}

Я обновил несколько элементов в вашем коде: data для краткости, длина ссылки для демонстрационных целей, уменьшение непрозрачности с 1 до 0,1 (по вашему вопросу) и использование кругов, а не крестов для узла, поскольку кресты кажутся очень сложными для манипулирования. В противном случае рабочий пример соответствует вашему вопросу:

// SVG dimensions set to full width and height of the screen
const width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
const height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

const drawChart = (data) => {

  // Create detached <svg> element.
  const vis = d3.select('.main_container')
    .append("svg")
    .attr("width", width)
    .attr("height", height);

  const g = vis.append("g");
  const simulation = d3.forceSimulation(data.nodes)
    .force("charge", d3.forceManyBody().strength(-300))
    .force("link", d3.forceLink(data.links).id(d => d.id).distance(100)) // reduced from 300 for demo purpose
    .force("center", d3.forceCenter(width / 2, height / 2))
    .force("collide", d3.forceCollide().strength(10))

  const link = vis.selectAll("line")
    .data(data.links)
    .join("line")
    .attr("stroke", 'grey')
    .attr("fill", "red")
    .attr("opacity", 1) // changed to 1 so we can lower opacity


  const drag = (simulation) => {
    const dragstarted = (event) => {
      if (!event.active) simulation.alphaTarget(0.3).restart();
      event.subject.fx = event.subject.x;
      event.subject.fy = event.subject.y;

      // update link opacity to 0.1 for non-connected nodes
      link.each(function(d) {
        const test = d.source.id === event.subject.id || d.target.id === event.subject.id;
        d3.select(this).attr("opacity", test ? 1 : 0.1);
      });
    }

    const dragged = (event) => {
      event.subject.fx = event.x;
      event.subject.fy = event.y;


    }

    const dragended = (event) => {
      if (!event.active) {
        simulation.alphaTarget(0)
      };
      event.subject.fx = null;
      event.subject.fy = null;

      // reset link opacity to 1
      link.attr("opacity", 1);
    }

    return d3.drag()
      .on("start", dragstarted)
      .on("drag", dragged)
      .on("end", dragended);
  }

  // for demo purpose replaced cross with circle
  // as the crosses are difficult to drag

      .attr("x2", d => d.target.x)
      .attr("y2", d => d.target.y)
  })

  // zoom block  
  const handleZoom = (e) => {
    d3.select('svg g')
      .attr('transform', e.transform);
  }

  const zoom = d3.zoom()
    .scaleExtent([0.1, 3.5]) //[k0, k1] where k0 is the minimum allowed scale factor and k1 is the maximum allowed scale factor, and returns this zoom behavior. If extent is not specified, returns the current scale extent, which defaults to [0, ∞]. The scale extent restricts zooming in and out.

Большое спасибо, Робин. Поэтому нет необходимости задействовать узлы, просто работайте напрямую со ссылками, но как в dragStarted, так и в dragEnded .
