我有以下指令:
import Vue from 'vue'
const Dialog = Vue.extend({
template: `
<div v-if="show" class="modal">
<div class="modal-body">
<div class="modal-header"><h3>Aktion bestätigen</h3></div>
<div class="modal-content">
<div class="uk-flex">
<div class="uk-margin-small-right">
<span uk-icon="icon: question; ratio: 3"></span>
</div>
<div>
Are You sure?
</div>
</div>
<hr>
<div class="uk-flex uk-flex-right">
<button class="uk-button uk-button-danger uk-margin-small-right" @click="confirmed">Yes</button>
<button class="uk-button uk-button-default" @click="show = false">Cancel</button>
</div>
</div>
</div>
</div>
`
});
Vue.directive('confirm', {
bind(el, binding, vnode) {
let confirm_method = binding.value;
el.handleClick = (e) => {
const data = { confirmed: confirm_method , show: true};
let dialog = new Dialog({data: data}).$mount();
document.getElementsByTagName('body')[0].appendChild(dialog.$el);
}
el.addEventListener('click', el.handleClick);
},
unbind(el) {
el.removeEventListener('click', el.handleClick);
}
});
这很好用。当我点击“取消”时,模态关闭。当我单击“是”时,在Vue模板中定义的方法
<button v-confirm="delete">delete</button>
已执行。
但是模态没有出现。如何在方法执行后告诉模态关闭,并在出现错误时显示错误消息?

您可以将methods
传递给Dialog:
Vue.directive('confirm', {
bind(el, binding, vnode) {
let confirm_method = binding.value;
el.handleClick = (e) => {
const data = { confirmed: confirm_method , show: true};
let dialog = new Dialog({
data: data,
methods: {
confirmedInternal() {
this.show = false
this.confirmed()
}
}
}).$mount();
document.getElementsByTagName('body')[0].appendChild(dialog.$el);
}
el.addEventListener('click', el.handleClick);
},
unbind(el) {
el.removeEventListener('click', el.handleClick);
}
});
然后在点击confirmedInternal
按钮时调用yes
<button class="uk-button uk-button-danger uk-margin-small-right" @click="confirmedInternal">Yes</button>

Vue文档有pretty good example of modal
关键选项是$emit('close')
。您可以在方法成功时调用$emit('close')
。
// register modal component
Vue.component('modal', {
template: '#modal-template'
})
// start app
new Vue({
el: '#app',
data: {
showModal: false
}
})

.modal-mask {
position: fixed;
z-index: 9998;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, .5);
display: table;
transition: opacity .3s ease;
}
.modal-wrapper {
display: table-cell;
vertical-align: middle;
}
.modal-container {
width: 300px;
margin: 0px auto;
padding: 20px 30px;
background-color: #fff;
border-radius: 2px;
box-shadow: 0 2px 8px rgba(0, 0, 0, .33);
transition: all .3s ease;

}
.modal-header h3 {
margin-top: 0;
color: #42b983;
}
.modal-body {
margin: 20px 0;
}
.modal-default-button {
float: right;
}
/*

.modal-enter {
opacity: 0;
}
.modal-leave-active {

}
.modal-enter .modal-container,
.modal-leave-active .modal-container {
