我怀疑如何创建动态组件，而不是标签<component :is=''>，如果没有，则该组件在DOM中不存在，并通过javascript插入。
在jquery中添加$("body").append("<div class="modal"></div>")，以添加新的模式
示例：https://jsfiddle.net/yu9oca2n/
代码：https://codesandbox.io/embed/vue-template-5cx5l?fontsize=14
代码示例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>

</body>
</html>伴侣父母
<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>
组件模式
<template>
<div>MODAL {{num}}</div>
</template>
<script>
export default {
name: "modal",
props: ["num"],
data: function() {
return {};
},
methods: {}
};
</script>
在组件数据中创建一个数组，并为数组中的每个项目显示一个模态
<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>
