resolveInject()函数就是解析标准格式 inject 配置,并将上层组件的provide的值或者default默认值绑定到函数返回对象中;如果这两个都没有,则会提示错误信息 “injection xx not found” 2. initProvide 注入数据初始化 初始化注入数据的过程也很简单,整个过程其实与initInjection类似。其函数定义如下: export function in...

}elseif(process.env.NODE_ENV!=='production') {warn(`Injection "${key}" not found`, vm) } } }returnresult } } 从源码上看,可以看出provide/inject的实现很简单,代码量也很少,几十行就搞定了。 下面我们来分析代码逻辑,结合上面的链路图一起看, 初始化Vue,首先初始化inject,如果是根组件,则是没有...

This object contains the properties that are available for injection into its descendants. You can use ES2015 Symbols as keys in this object, but only in environments that natively support Symbol and Reflect.ownKeys. The inject option should be either: an array of strings, or an object where ...
