HTML | DOM Paragraph Object

The DOM paragraph object is used to represent the HTML <p> element. The p element is accessed by getElementById().

Syntax:

document.getElementById("id");

Where ‘id’ is the ID assigned to the p tag.

Below programs illustrate the p object:

Example-1: In the below program the paragraph element is assigned the id = “s”. On click of the button, the paragraph element is accessed and the color of the paragraph text is changed.

<!DOCTYPE html>  
<html>  
<body>  
    <center>  
        <h1 style = "color:green;" >  
          GeeksForGeeks  
        </h1>  
        <h2>DOM paragraph Object</h2>  
  
        <button onclick="Geeks()">Click Here</button> 
  
        <p id="s">A computer science   
        portal for geeks.</p> 
          
        <script> 
        function Geeks() { 
          var txt = document.getElementById("s"); 
          txt.style.color = "green"; 
        } 
        </script> 
</body>  
</html>  

Output:
Before clicking on button:
paragraph
After clicking on button:

Example-2: Paragraph Object can be created by using the document.createElement method. In the below program we create a paragraph element and append a text node to it.

<!DOCTYPE html>  
<html>  
<body>  
<center> 
        <h1 style = "color:green;" >  
          GeeksForGeeks  
        </h1>  
  
        <h2>DOM paragraph Object</h2>  
  
        <button onclick="Geeks()">Click Here!</button><br><br> 
  
        <div id="p"></div> 
  
        <script> 
        function Geeks() { 
          var txt = document.createElement("P"); 
  
          var t = document.createTextNode("A computer  
                               science portal for geeks."); 
  
          txt.appendChild(t); 
  
          document.getElementById("p").appendChild(txt); 
        } 
        </script> 
</body>  
</html>  

Output:
Before clicking on button:
