You are developing a customer web form that includes the following HTML.
<input id = “txtValue” />
A customer must enter a value in the text box prior to submitting the form.
You need to add validation to the text box control.
Which HTML should you use?
A.
<input id=”txtValue” type=”text” required=”required”/>
B.
<input id=”txtValue” type=”text” pattern=”[A-Za-z]{3}” />
C.
<input id=”txtValue” type=”required” />
D.
<input id=”txtValue” type=”required” autocomplete=”on” />

Despite the most correct seems answer A, it is bad formatted because the “required” attribute is a boolean value and when present, it specifies that an input field must be filled out before submitting the form.
Should be like this:
“”
A is correct but not nice.
