vue-async-computed With this plugin, you can have computed properties in Vue that are computed asynchronously. Without using this plugin, you can't do this: exportdefault{ data () {return{userId:1} },computed: { username () {returnfetch(`/get-username-by-id/${this.userId}`)// This...

vue中computed属性值的计算函数只能是同步的,于是有了vue-async-computed 这个插件。其实我觉得这个插件非常有用,相比较之下这个项目的star就比较少了。 处于练习的目的(我不想三十岁就上天台),我试着实现这个这个插件的功能。有这么几个问题需要解决: 1。如何获取开发者定义的asyncComputed? 使用$options属性。之前我...
在Vue 3中,computed属性是一个强大的特性,用于声明式地计算依赖于其他响应式状态的值。然而,直接在computed属性中使用async函数是不被支持的,因为computed属性需要返回一个同步的结果,而async函数总是返回一个Promise。下面我将详细解释这一点,并提供替代方案。 1. Vue3中computed属性的基本作用和行为 computed属性在Vu...
