我今天遇到了Vue的一个问题。
在函数中,我无法从状态获取元素。 但是,当我使用console.log()状态时,该元素在那里。 如何解决?
代码:
export const actions: ActionTree<IState, IState> = {
getUsers(context) {
// eslint-disable-next-line no-console
console.log('getUsers().context=', context);
// eslint-disable-next-line no-console
console.log('getUsers().context.state=', context.state);
// eslint-disable-next-line no-console
console.log('getUsers().context.state.baseURL=', context.state.baseURL);
// do something...
}
}
控制台的日志:
第一个日志正常。我可以看到 baseURL 的值。

感谢@acdcjunior和@TimWickstrom,
我终于找到了原因和解决方案。这是代码比较。主要区别在于在何处加载配置值。
原始代码(有问题):
new Vue({
router,
store,
vuetify,
render: h => h(App),
}).$mount('#app');
store.commit(UPDATE_BASE_URL, {
baseURL: process.env.VUE_APP_BASE_URL,
});
工作代码:
new Vue({
router,
store,
vuetify,
created() {
this.$store.commit(UPDATE_BASE_URL, {
baseURL: process.env.VUE_APP_BASE_URL,
});
},
render: h => h(App),
}).$mount('#app');
