vk-uview-ui/libs/function/deepMerge.js

同时支持 Vue3.0 和 Vue2.0，你没看错，现在 uView 支持 Vue3.0 了！（不支持nvue，此版本为uView1.0的分支）

import deepClone from "./deepClone";

// JS对象深度合并
function deepMerge(target = {}, source = {}) {
	target = deepClone(target);
	if (typeof target !== 'object' || typeof source !== 'object') return false;
	for (var prop in source) {
		if (!source.hasOwnProperty(prop)) continue;
		if (prop in target) {
			if (typeof target[prop] !== 'object') {
				target[prop] = source[prop];
			} else {
				if (typeof source[prop] !== 'object') {
					target[prop] = source[prop];
				} else {
					if (target[prop].concat && source[prop].concat) {
						target[prop] = target[prop].concat(source[prop]);
					} else {
						target[prop] = deepMerge(target[prop], source[prop]);
					}
				}
			}
		} else {
			target[prop] = source[prop];
		}
	}
	return target;
