Mixins.js bug 修改

[to-thomassun]

merge函数中有一个bug。
options = { ...mixin, ...options } 应当修改为 options[key] = value
详情如下：

function merge (mixins, options) {
mixins.forEach((mixin) => {
if (Object.prototype.toString.call(mixin) !== '[object Object]') {
throw new Error('mixin 类型必须为对象！')
}
for (let [key, value] of Object.entries(mixin)) {
if (originProperties.includes(key)) {
options[key] = { ...value, ...options[key] }
} else if (originMethods.includes(key)) {
const originFunc = options[key];
options[key] = function (...args) {
value.call(this, ...args);
return originFunc && originFunc.call(this, ...args)
}
} else {
// options = { ...mixin, ...options }
options[key] = value
}
}
})
return options
