HTML DOM Figcaption用法及代碼示例

HTML DOM中的Figcaption對象用於表示HTML <figcaption>元素。 figcaption元素由getElementById()訪問。

用法:

document.getElementById("ID");

其中ID代表元素ID。

範例1：

<!DOCTYPE html>  
<html>  
    <head>  
        <title> 
            HTML DOM figcaption Object 
        </title>  
          
        <style>  
            body {  
                text-align:center;  
            }  
            h1 {  
                color:green;  
            }  
        </style>  
    </head>  
      
    <body>  
        <h1>GeeksforGeeks</h1>  
          
        <h2>DOM Figcaption Object</h2>  
          
        <figure>  
            <img src=  
    "https://media.geeksforgeeks.org/wp-content/uploads/geeks-25.png"
            alt="gfglogo" style="width:50%">  
              
            <figcaption id = "GFG"> 
                GeeksforGeeks Logo 
            </figcaption>  
        </figure> 
          
        <button onclick = "Geeks()"> 
            Submit 
        </button> 
          
        <script> 
        function Geeks() { 
            var gfg = document.getElementById("GFG"); 
            gfg.style.color = "green"; 
            gfg.style.fontSize = "20px";

            alt = "gfglogo" style = "width:50%"> 
        </figure>  
          
        <button onclick = "Geeks()"> 
            Submit 
        </button> 
          
        <!-- script to add figcaption object -->
        <script> 
            function Geeks() { 
                var x = document.createElement("FIGCAPTION"); 
                var y = document.createTextNode("GeeksForGeeks Logo") 
                x.appendChild(y); 
                x.style.color = "green"; 
                document.body.appendChild(x);
