How can I remove a child node in HTML using JavaScript?

Question

Is there a function like document.getElementById(\"FirstDiv\").clear()?

Answer 1

    var p=document.getElementById('childId').parentNode;
    var c=document.getElementById('childId');
    p.removeChild(c);
    alert('Deleted');

p is parent node and c is child node
parentNode is a JavaScript variable which contains parent reference

Easy to understand
