JSDoc:返回对象结构

2020/11/12 04:22 · javascript ·  · 0评论

如何将返回的对象的结构告诉JSDoc。我找到了@return {{field1: type, field2: type, ...}} description语法并尝试了它:

/**
 * Returns a coordinate from a given mouse or touch event
 * @param  {TouchEvent|MouseEvent|jQuery.Event} e    
 *         A valid mouse or touch event or a jQuery event wrapping such an
 *         event. 
 * @param  {string} [type="page"]
 *         A string representing the type of location that should be
 *         returned. Can be either "page", "client" or "screen".
 * @return {{x: Number, y: Number}} 
 *         The location of the event
 */
var getEventLocation = function(e, type) {
    ...

    return {x: xLocation, y: yLocation};
}

成功解析后,最终的文档仅说明:

Returns: 
    The location of an event
    Type: Object

我正在开发一个API,需要人们知道他们将返回的对象。在JSDoc中可以吗?我正在使用JSDoc3.3.0-beta1。

使用@typdef分别定义您的结构

/**
 * @typedef {Object} Point
 * @property {number} x - The X Coordinate
 * @property {number} y - The Y Coordinate
 */

并将其用作返回类型:

/**
 * Returns a coordinate from a given mouse or touch event
 * @param  {TouchEvent|MouseEvent|jQuery.Event} e    
 *         A valid mouse or touch event or a jQuery event wrapping such an
 *         event. 
 * @param  {string} [type="page"]
 *         A string representing the type of location that should be
 *         returned. Can be either "page", "client" or "screen".
 * @return {Point} 
 *         The location of the event
 */
var getEventLocation = function(e, type) {
    ...

    return {x: xLocation, y: yLocation};
}

除了已经发布的建议之外,您还可以使用以下格式:

/**
 * Get the connection state.
 *
 * @returns {Object} connection The connection state.
 * @returns {boolean} connection.isConnected Whether the authenticated user is currently connected.
 * @returns {boolean} connection.isPending Whether the authenticated user's connection is currently pending.
 * @returns {Object} connection.error The error object if an error occurred.
 * @returns {string} connection.error.message The error message.
 * @returns {string} connection.error.stack The stack trace of the error.
 */
getConnection () {
  return {
    isConnected: true,
    isPending: false,
    error
  }
}

这将提供以下文档输出:

    Get the connection state.

    getConnection(): Object

    Returns
    Object: connection The connection state.
    boolean: connection.isConnected Whether the authenticated user is currently connected.
    boolean: connection.isPending Whether the authenticated users connection is currently pending.
    Object: connection.error The error object if an error occurred.
    string: connection.error.message The error message.
    string: connection.error.stack The stack trace of the error.

一个干净的解决方案是编写一个类并将其返回。

/** 
 *  @class Point
 *  @type {Object}
 *  @property {number} x The X-coordinate.
 *  @property {number} y The Y-coordinate.
 */
function Point(x, y) {
  return {
        x: x,
        y: y
    };
}

/**
 * @returns {Point} The location of the event.
 */
var getEventLocation = function(e, type) {
    ...
    return new Point(x, y);
};
