HTML | DOM Paragraph Object

Last Updated : 22 Jan, 2019

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:
