HTML <textarea> required Attribute
The required attribute of the <textarea> element in HTML is used to let visitors know that this textarea field is to be filled before submitting the form. If a visitor clicks on Submit, without filling the textarea set with required attribute, then the form won’t submit.
Following is the syntax −
<textarea required>
Let us now see an example to implement the required attribute of the <textarea> element −
Example
<!DOCTYPE html> <html> <body> <h2>Subject-wise rank</h2> <form action=""> <label for="stinfo">Student:</label> <input type="text" id ="stinfo"><br> <label for="sub">Subject:</label> <input type="text"><br> <label for="rank">Rank:</label> <input type="number"><br> <label for="marks">Marks:</label> <input type="number"><br> <label for="remark">Remarks</label><br> <textarea rows="6" cols="70" required></textarea><br> <input type="submit"> </form> </body> </html>
Output
In the above example, we have a form with fields and a button −
<form action=""> <label for="stinfo">Student:</label> <input type="text" id ="stinfo"><br> <label for="sub">Subject:</label> <input type="text"><br> <label for="rank">Rank:</label> <input type="number"><br> <label for="marks">Marks:</label> <input type="number"><br> <label for="remark">Remarks</label><br> <textarea rows="6" cols="70" required></textarea><br> <input type="submit"> </form>
We have set a textarea and set it is as required, therefore if the form is submitted without filling the textarea, then a warning message would be visible. This won’t even submit the form if the textarea is empty −
<textarea rows="6" cols="70" required></textarea>
