create dynamic components VUE
Question
I have a doubt on how to create dynamic components, and not by the label <component:is=''> , if not, this component does not exist in the DOM, and through javascript insert it.
As in jquery add a $("body").append("<div class="modal"></div>") , to add a new modal
Example: https://jsfiddle.net/yu9oca2n/
Code: https://codesandbox.io/embed/vue-template-5cx5l?fontsize=14
JQuery
code example JQuery
$("#button").click(function() { $("#modals").append("<div class='modal'>modal</div>"); });
<:doctype html> <html> <head></head> <body> <div id="modals"></div> <hr> <button id="button">add input tag</button> <script src="https.//cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> </body> </html>
VUE
Componet Parent
<template>
<div>
<p>Hello</p>
<hr>
<a @click="insertModal">Insert Modal</a>
<hr>
<modal num="1"></modal>
</div>
</template>
<script>
export default {
name: "HelloWorld",
props: {},
methods: {
insertModal() {
/**
* How to do so that when you enter here,
* add one more modal, without putting this in a list,
* because this modal can be called from anywhere on the web
*
* MODAL : <modal num="_x_" @clickEvent="eventClick"></modal>
*/
// ??
}
},
eventClick() {
/** modal event click */
}
};
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
</style>
Component modal
<template>
<div>MODAL {{num}}</div>
</template>
<script>
export default {
name: "modal",
props: ["num"],
data: function() {
return {};
},
methods: {}
};
</script>

Create an array in component data and show a modal per every item in array
<template>
<div>
<p>Hello</p>
<hr>
<a @click="insertModal">Insert Modal</a>
<hr>
<modal v-for="num in modals" :num="num" :key="num" @clickEvent="eventClick($event, num)"></modal>
<modal num="1"></modal>
</div>
</template>
<script>
export default {
name: "HelloWorld",
props: {},
data() {
return {
modals: [],
};
},
methods: {
insertModal() {
this.modals.push(this.modals.length)
}
},
eventClick($event, modalNumber) {
/** modal event click */
}
};
</script>
