问题描述
我正在尝试向自定义vue组件添加一个简单的。我没有使用webpack所以我想避免现成的 .vue 组件，而我更了解如何添加简单的javascript到vue。
I'm trying to add a simple date-picker to a custom vue component. I'm not using webpack so I want to avoid ready made .vue components and I rather understand how to add simple javascript to vue.
我正在关注
我也见过但我无法设置日期选择器。
I've also seen this codepen but I can't manage to make the date picker appear.
这是我的：
Html：
<div class="app">
<datepicker id='date-elem'></datepicker>
</div>
app.js：
Vue.component('date-picker', {
extends: Flatpickr,
mounted () {
this.Flatpickr(date-elem, {})}
})
如何在Vue组件中轻松集成vanilla js而无需.vue文件，webpack等？
How can I easily integrate vanilla js in a Vue component without the need of .vue files, webpack etc?
推荐答案
所以你在这里有一些误解。要使它成为一个组件（一个非常基本的组件），你可以这样做。
So you have a few misconceptions here. To make this a component (a very basic component), this is how you might do it.
在Vue中，你通常不会扩展外部Javascript库。您通常会将其称为包装器组件。本质上，Vue组件处理与外部库的所有交互。在这种情况下，您想使用Flatpickr。从中，您需要使用新的Flatpickr（元素） ，选项）。所以我们可以在挂载的事件中执行此操作，传递这个。$ el ，它将指向根Vue组件元素。
In Vue, you're not going to typically extend an external Javascript library. What you will typically make is called a wrapper component. Essentially, a Vue component that handles all the interaction with the external library. In this case you want to use Flatpickr. From the documentation, you need to use new Flatpickr(element, options). So we can do that in the mounted event, passing this.$el which will point to the root Vue component element.
Vue.component('date-picker', {
template: "<input type='text'>",
mounted () {
new Flatpickr(this.$el, {})
}
})
这是您更新的。
但是这个组件做的不多。它只允许你选择一个日期。要允许该日期在组件之外，我们希望将其扩展为支持 v-model 。以下是你可以这样做的方法。
But this component doesn't do very much. It just allows you to pick a date. To allow that date to be used outside the component, we want to extend it to support v-model. Here's how you might do that.
Vue.component('date-picker', {
props:["value"],
data(){
return {
selectedDate: this.value
}
},
template: "<input type='text' v-model='selectedDate' @input='onInput'>",
methods:{
onInput(){
this.$emit('input', this.selectedDate)
}
},
mounted () {
new Flatpickr(this.$el, {})
}
})
现在，您可以像这样使用它。
Now, you can use it like this.
<date-picker v-model="selectedDate"></date-picker>
且selectedDate将收到您选择的日期。
And selectedDate will receive the date you pick.
显示了这一点。
