root
Using the root property to access the root node of an element.
On a webpage, the root node of ordinary elements is an instance of document.

<ul>
<li id="target">I am target</li>
</ul>
<div id="logger" style="padding:16px;color:green;"></div>
<script>
setTimeout(()=>{
$('#logger').text = $("#target").root.ele === document;
}, 500);
</script>
Elements Inside Shadow DOM
Because the elements inside a component are isolated from the external environment, the root property of the elements inside the shadow node is the shadow root node.
<template component>
<ul>
<li>item 1</li>
<li id="target">item 2</li>
<li>item 3</li>
</ul>
<h3>logger1:</h3>
<div id="logger1" style="color:red;">{{l1}}</div>
<h3>logger2:</h3>
<div id="logger2" style="color:green;">{{l2}}</div>
<script>
export default {
tag: "test-root",
data: {
l1: "",
l2: ""
},
ready() {
this.l1 = this.shadow.$("#target").root === this.shadow;
this.l2 = this.root.ele === document;
}
};
</script>
</template>
