Sau đây là mã để giải cấu trúc lồng nhau trong JavaScript -
Ví dụ
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
.sample,.result {
font-size: 18px;
font-weight: 500;
color: red;
}
.result {
color: rebeccapurple;
}
</style>
</head>
<body>
<h1>Nested de-structuring in JavaScript.</h1>
<div><pre class="sample"></pre></div>
<div><pre class="result"></pre></div>
<button class="Btn">CLICK HERE</button>
<h3>Click on the above button to destructure the above nested array and object</h3>
<script>
let sampleEle = document.querySelector(".sample");
let resultEle = document.querySelector(".result");
let obj = {
Name: {
firstName: "Rohan",
lastName: "Sharma",
},
age: 22,
};
let arr = [22, 33, ["a", "b"]];
sampleEle.innerHTML = '{Name:{firstName: "Rohan", lastName: "Sharma"},age: 22} <br>';
sampleEle.innerHTML += "[22,33,['a','b']";
let {
Name: { firstName, lastName },
age,
} = obj;
let a, b, c, d;
[a, b, [c, d]] = arr;
document.querySelector(".Btn").addEventListener("click", () => {
resultEle.innerHTML += `firstName=${firstName} lastName=${lastName} age=${age}
'<br>`;
resultEle.innerHTML += `a=${a} b=${b} c=${c} d=${d} '<br>`;
});
</script>
</body>
</html>
