HTML
The form attribute of the <button> element is used to specify the forms wherein the button belongs to.
Following is the syntax −
<button form="id">
The id above is the if of the form wherein the button belongs to.
Let us now see an example to implement the form attribute of the <button> element−
Example
<!DOCTYPE html> <html> <body> <h2>Points</h2> <form action="" method="get" id="form1"> Player: <input type="text"><br> Rank: <input type="number"><br> Points: <input type="number"><br> </form> <button type="submit" form="form1" value="Submit">Click to Submit</button> </body> </html>
This will produce the following output. The button is part of the form−
In the above example, we have set a form and added form elements−
<form action="" method="get" id="form1"> Player: <input type="text"><br> Rank: <input type="number"><br> Points: <input type="number"><br> </form>
With that, we have set a button outside the form−
<button type="submit" form="form1" value="Submit">Click to Submit</button>
Since we have set the form id in the button, therefore it would still belong to the same form. This is possible using the <button> form attribute.
