要在 G6 中实现将已存在的边拖动到另一个节点,可以通过监听边的点击事件,然后在拖动过程中更新边的目标节点。以下是一个简单的实现步骤:
以下是一个简单的代码示例: // 假设 graph 是已经初始化的 G6 图实例
let draggingEdge = null;
graph.on('edge:click', (evt) => {
const { item } = evt;
draggingEdge = item;
});
graph.on('mousemove', (evt) => {
if (draggingEdge) {
const point = { x: evt.x, y: evt.y };
// 更新边的目标位置为鼠标当前位置
graph.updateItem(draggingEdge, {
target: point,
});
}
});
graph.on('mouseup', (evt) => {
if (draggingEdge) {
const targetNode = graph.findNearestNode(evt);
if (targetNode) {
// 更新边的目标节点为最近的节点
graph.updateItem(draggingEdge, {
target: targetNode.getID(),
});
}
draggingEdge = null;
}
}); 请注意,这只是一个基本的实现,可能需要根据具体需求进行调整和优化。 如果有其他问题或需要进一步的帮助,请随时告诉我! 🪧 TipsFor further assistance, please describe your question in the comments and @petercat-assistant to start a conversation with me. |
