Vue JS 2.6.10
我读过很多关于如何创建自定义指令的帖子,以便您可以检测到弹出菜单外部的单击,以便可以将其关闭。我无法完全让它工作,因为我有一个打开菜单的按钮,单击它会触发“关闭”行为。
这是我的主视图Logbook.vue,其中包含打开菜单的按钮:

// --- Logbook.vue ---
<script>
export default {
name: 'Logbook',
components:{
Years
},
methods:{
clickYears: function(){
this.$refs.Years.show = true
}
}
}
</script>
<template>
<div id="current-year">
<a href="#year" ref="yearButton" v-on:click.prevent="clickYears">{{ currentYear }}</a>
<Years ref="Years" v-on:selectYear="yearSelected" />
</div>
</template>

//--- Years.vue ---
<script>
import Vue from 'vue'
//Custom directive to handle clicks outside of this component
Vue.directive('click-outside', {
bind: function (el, binding, vnode) {
window.event = function (event) {
if (!(el == event.target || el.contains(event.target))) {
vnode.context[binding.expression](event)
}
};
document.body.addEventListener('click', window.event)
},
unbind: function (el) {
document.body.removeEventListener('click', window.event)
}
})
export default{
name: 'Years',
data() {
return {
show: false
}
},
methods:{
close: function(){
this.show = false
}
}
}
</script>
<template>
<div id="years" v-show="show" v-click-outside="close">
<!-- Years listed here... -->
</div>
</template>

close当我单击组件外部时,该方法会正确触发Years,但问题是我无法从一开始就打开菜单,Years因为单击按钮也会触发该close行为,因为它也Years 组件之外。
有人克服了这个问题吗?有任何想法吗?
尝试这个
...
methods:{
clickYears: function(event){
this.$refs.Years.show = true
event.stopPropagation();
}
}
