我正在使用 Vuetify 抽屉导航。打开它的元素位于标题中的单独组件(v-toobar-side-icon)中。我将抽屉的打开/关闭状态存储在商店中。我正在使用计算方法来获取抽屉的状态。我不断收到错误消息Computed property "drawerState" was assigned to but it has no setter.
我知道这是因为我必须使用 v-model控制抽屉的可见性。我不想使用计算的 setter 来更改抽屉的状态，我想使用 click 方法。
我尝试使用 :value而不是 v-model但我也无法让它正常工作。我遇到的实际问题是抽屉导航控件(打开/关闭)在主页上工作，但是一旦我导航到另一个页面，它们就会停止工作。如果我导航回主页，它们仍然无法工作。 getter 和 setter 正在改变状态并更新它们应该的方式，但是 isActive抽屉导航的属性保持 false .

最佳答案
如果您不想使用 v-model ，您可以通过 :value 将其替换为值的绑定(bind)属性，如你所说。但是如果你这样做，你将不得不收听@input。事件，当值改变时引发。
在我看来，你可以通过替换 v-model 来实现你想要做的事情。对于 :value="drawerState"并通过绑定(bind)新方法updateDrawerState到@input事件。
您的 NavDrawer.vue将从
<template lang="pug">
v-navigation-drawer(:value="drawerState" @input="updateDrawerState" dark fixed temporary)
你必须在同一个组件中添加这个方法:
updateDrawerState(state) {
if (state) {
this.closeDrawer();
}
}
仅供引用:您可以通过在您的计算中添加一个 setter 来实现几乎相同的事情:
computed: {
drawerState: {
get() {
return this.$store.getters.navDrawer;
},
set(state) {
if (state) {
this.closeDrawer();
}
},
},
},
