JavaScript innerHTML
In JavaScript, innerHTML refers to the content of an HTML element. Therefore, the innerHTML property sets/returns content to/of specified HTML element. For example:
<!DOCTYPE html> <html> <body> <p>The value is <span id="x"></span></p> <script> var element = document.getElementById("x"); element.innerHTML = 10; </script> </body> </html>
The value is
In above example, the following statement:
var element = document.getElementById("x");
is used to initialize the element whose ID value is x to element variable. And using the following statement:
element.innerHTML = 10;
The value 10 set as the content of returned element. In case, if the returned element already has some content, then the content will be removed and the new content using the innerHTML will get set to it.
To set/get the content of an HTML element using the innerHTML property, we need to get the element using any of the following methods:
- getElementById()
- getElementsByClassName()
- getElementsByName()
- getElementsByTagName()
- querySelector()
- querySelectorAll()
JavaScript innerHTML Syntax
The syntax of innerHTML property in JavaScript, is:
element.innerHTML
JavaScript innerHTML Example
<!DOCTYPE html> <html> <body> <p id="cc">The name of website is: codescracker.com</p> <p>The content of P tag, with cc as its ID value is: <span id="res"></span></p> <script> content = document.getElementById("cc").innerHTML; element = document.getElementById("res"); element.innerHTML = content; </script> </body> </html>
The name of website is: codescracker.com
The content of P tag, with cc as its ID value is:
The above example, can also be written as:
<!DOCTYPE html> <html> <body> <p id="cc">The name of website is: codescracker.com</p> <p>The content of P tag, with cc as its ID value is: <span id="res"></span></p> <script> document.getElementById("res").innerHTML = document.getElementById("cc").innerHTML; </script> </body> </html>
In above example, the following JavaScript code:
document.getElementById("cc").innerHTML
returns the content of an HTML element, whose ID value is cc. And this content will be initialized to an HTML element whose ID value is res.
