Question

我正在尝试将 d3-tip 导入我的一个打字稿类。

d3-tip 的

index.d.ts如下

import { Primitive } from "d3";

declare module "d3" {
    type TooltipDirection = ("n" | "s" | "e" | "w" | "nw" | "ne" | "sw" | "se");
    interface Tooltip {
        hide(): Tooltip;
        show(): Tooltip;
        show<Datum>(data: Datum[]): Tooltip;
        show(target: SVGElement): Tooltip;
        show<Datum>(data: Datum[], target: SVGElement): Tooltip;
        attr(name: string): string;
        attr(name: string, value: Primitive): Tooltip;
        attr<Datum>(name: string, value: (datum: Datum, index: number, outerIndex: number) => Primitive): Tooltip;
        attr<Datum>(obj: { [key: string]: Primitive | ((datum: Datum, index: number, outerIndex: number) => Primitive) }): Tooltip;
        style(name: string): string;
        style(name: string, value: Primitive, priority?: string): Tooltip;
        style<Datum>(name: string, value: (datum: Datum, index: number, outerIndex: number) => Primitive, priority?: string): Tooltip;
        style<Datum>(obj: { [key: string]: Primitive | ((datum: Datum, index: number, outerIndex: number) => Primitive) }, priority?: string): Tooltip;
        offset(): [number, number];
        offset(tuple: [number, number]): Tooltip;
        offset<Datum>(func: (datum: Datum, index: number, outerIndex: number) => [number, number]): Tooltip;
        direction(): TooltipDirection;
        direction(direction: TooltipDirection): Tooltip;
        direction<Datum>(func: (datum: Datum, index: number, outerIndex: number) => TooltipDirection): Tooltip;
        html(): string;
        html(content: string): Tooltip;
        html<Datum>(func: (datum: Datum, index: number, outerIndex: number) => string): Tooltip;
        rootElement(): HTMLElement;
        rootElement(element: HTMLElement): Tooltip;
        rootElement<Datum>(func: (datum: Datum, index: number, outerIndex: number) => HTMLElement): Tooltip;
        destroy(): Tooltip;
    }
    export function tip(): Tooltip;
}

我试图这样导入

import * as d3tip from 'd3-tip';

或类似的

import tip from 'd3-tip';

但在任何情况下我都无法使用tip函数。

Answer 1

您可以尝试通过这种方式做到这一点：

import d3Tip from "d3-tip";
d3.tip = d3Tip;

Answer 2

导入，对我有用：我正在使用d3v5和angular 8

从“ d3-tip”导入d3Tip； const tip = d3Tip（）;

无法将d3-tip导入Typescript类
