Imagine I have a vuejs component named child-component that is inserted into a parent component in the following manner.
<child-component>
<div>Hello</div>
</child-component>
Please note, this does not represent the template of the child component. Instead, it shows how the child component is included within the parent.
Is there a way to retrieve the innerHTML, for example <div>Hello</div>, from the child component as a string?
When working inside the component called child-component, you can access the HTML content in the mounted lifecycle hook using this.$el.innerHTML. The parsed virtual nodes (vnodes) can be accessed through this.$slots.default.
console.clear()
Vue.component("child-component",{
template: `<div><slot/></div>`,
mounted(){
console.log("HTML", this.$el.innerHTML)
}
})
new Vue({
el: "#app"
})<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.3/vue.min.js"></script>
<div id="app">
<child-component>
<div>Hello</div>
</child-component>
</div>If you are looking to access the innerHTML of a child component from the parent component in Vue, you can consider using Vue Child Component Refs.
To achieve this, simply add a ref attribute to your child component:
<child-component ref="mychildcomponent">
<div>Hello</div>
</child-component>
Then in the parent methods, you can use the following code:
let childEl = this.$refs.mychildcomponent
This will allow you to reference the entire child component. To get the innerHTML, you can go a step further with code like this:
let childEl = this.$refs.mychildcomponent.$el.innerHTML
By doing so, you will obtain a string containing the innerHTML of the child component.
For more information on this topic, you can refer to the following link: https://v2.vuejs.org/v2/guide/components.html#Child-Component-Refs
Alternatively, if you want to retrieve the innerHTML directly from the child component itself, you can use the following method:
let componentHTML = this.$el.innerHTML
I hope this explanation proves useful to you.
