HTML checked Attribute
The checked attribute in HTML is used to set that an <input> element is pre-selected when the page loads.
This works for input type radio and checkbox.
Let us work on the checked attribute for checkbox i.e. input type checkbox. Following is the syntax −
<input type=”checkbox” checked>
Above, we have set it checked since we wanted the checkbox to be selected when the web page loads. Let us now see an example to implement the checked attribute of the <input> element −
Example
<!DOCTYPE html> <html> <body> <h2>Register</h2> <form action="" method="get"> Id: <input type="text" name="id" placeholder="Enter UserId here..." size = "25"><br> Password: <input type="password" name="pwd" placeholder="Enter password here..."><br> DOB: <input type="date" name="dob" placeholder="Enter date of birth here..."><br> Telephone: <input type="tel" name="tel" placeholder="Enter mobile number here..."><br> Email: <input type="email" name="email" placeholder="Enter email here..." size = "35"><br><br> <input type="checkbox" name="vehicle" value="Bike" checked>Newsletter Subscription: <br> <button type="submit" value="Submit">Submit</button> </form> </body> </html>
Output
In the above example, we have a form with input elements and a button −
<form action="" method="get"> Id: <input type="text" name="id" placeholder="Enter UserId here..." size = "25"><br> Password: <input type="password" name="pwd" placeholder="Enter password here..."><br> DOB: <input type="date" name="dob" placeholder="Enter date of birth here..."><br> Telephone: <input type="tel" name="tel" placeholder="Enter mobile number here..."><br> Email: <input type="email" name="email" placeholder="Enter email here..." size = "35"><br><br> <input type="checkbox" name="vehicle" value="Bike" checked>Newsletter Subscription: <br> <button type="submit" value="Submit">Submit</button> </form>
We have set a checkbox using the input type checkbox. To set it checked when the web page loads, the checked attribute is used −
<input type="checkbox" name="vehicle" value="Bike" checked>Newsletter Subscription:
