Vue js So schließen Sie das Bootstrap-Dropdown-Menü, wenn Sie außerhalb des Menüs klicken
Dec 18 2020
Ich versuche, das Dropdown-Menü zu schließen, wenn der Benutzer außerhalb des Dropdown-Menüs klickt
header_component.vue
<div class="dropdown d-inline-block">
<a href="#" class="logo logo-dark">
<a href="javascript:void(0);" class="Logo-plus" @click="toggleMainMenu()">+</a>
<span class="logo-lg">
<img src="" alt="" height="25" id="topnav_heading_image">
</span>
</a>
<div class="dropdown-menu dropdown-menu-right" style="left: 0;right: auto;" v-bind:class="show_main_menu ? 'd-block' : ''">
..............
</div>
</div
Bisher habe ich versucht, dem Text beim Klicken einen addeventlistener hinzuzufügen und das Ereignis beim Schließen zu entfernen. Body Event wird nicht ausgelöst. Wie füge ich ein Ereignis zum Body Onclick hinzu?
methods:{
toggleMainMenu(){
this.show_main_menu = !this.show_main_menu;
this.show_sub_menu = false;
this.setBodyClass();
},
openSubMenu(menu_key){
let formData = new FormData();
formData.append("access_token", window.settings.access_token);
formData.append('menu_key',menu_key);
this.show_main_menu = false;
axios.post('/api/get_sub_menus', formData).then((response) => {
if(response.is_sub_menu == 0){
window.location.href = response.route;
}else{
this.sub_menus = _.chunk(_.toArray(response.data.sub_menu), 3);
this.show_sub_menu = true;
}
});
},
setBodyClass() {
var body = document.body;
body.classList.toggle('open');
if(this.show_main_menu){
body.addEventListener('click', e => {
this.toggleMainMenu;
});
} else {
body.removeEventListener('click', e => {
console.log('closed');
});
}
}
},
directives: {
"my-directive": {
bind: function(el, binding) {
alert('hello');
this.el.addEventListener('click', e => {
this.toggleMainMenu;
});
},
unbind: function(el) {
// Remove Event Listener
this.el.removeEventListener('click', e => {
console.log('closed');
});
}
}
Ich habe es auch mit Direktiven versucht, es funktioniert nicht
<body class="container-fluid p-0" v-my-directive="1">\
<body

Unten Code als mein Problem gelöst
mounted(){
document.addEventListener('click', this.close);
},
methods:{
toggleMainMenu(){
this.show_main_menu = !this.show_main_menu;
this.show_sub_menu = false;
},
openSubMenu(menu_key){
let formData = new FormData();
formData.append("access_token", window.settings.access_token);
formData.append('menu_key',menu_key);
this.show_main_menu = false;
axios.post('/api/get_sub_menus', formData).then((response) => {
if(response.is_sub_menu == 0){
window.location.href = response.route;
}else{
this.sub_menus = _.chunk(_.toArray(response.data.sub_menu), 3);
this.show_sub_menu = true;
}
});
},
close (e) {
if (!this.$el.contains(e.target)) {
this.show_main_menu = false;
}
}
},
beforeDestroy () {
document.removeEventListener('click',this.close);
},
