Lecture Notes Of Class 7 - Forms
Part 2 (Advanced Elements)
Introduction
to Form Controls
Forms are essential in web
development for collecting user input. Advanced form elements like checkboxes,
radio buttons, and select menus provide better user interactivity and cater to
various types of data inputs.
1.
Checkboxes
A checkbox allows users to select
one or more options from a list. Unlike radio buttons, checkboxes are not
mutually exclusive, meaning multiple checkboxes can be selected simultaneously.
HTML
Syntax:
<label>
<input type="checkbox"
name="interests" value="sports"> Sports
</label>
<label>
<input type="checkbox"
name="interests" value="music"> Music
</label>
<label>
<input type="checkbox"
name="interests" value="reading"> Reading
</label>
Key
Points:
- The name
attribute groups checkboxes together.
- Each
checkbox has a unique value to represent the selected option.
- Use
a checked attribute to set a checkbox as selected by default.
2. Radio
Buttons
Radio buttons allow users to
select only one option from a group.
HTML
Syntax:
<label>
<input type="radio"
name="gender" value="male"> Male
</label>
<label>
<input type="radio"
name="gender" value="female"> Female
</label>
<label>
<input type="radio"
name="gender" value="other"> Other
</label>
Key
Points:
- The name
attribute groups radio buttons, ensuring only one option is selectable at
a time.
- Each
radio button must have a unique value.
- Use
the checked attribute to preselect an option.
3. Select
Menus
A select menu provides a dropdown
list of options.
HTML
Syntax:
<select
name="country">
<option value="usa">United
States</option>
<option value="uk">United
Kingdom</option>
<option
value="india">India</option>
</select>
Key
Points:
- Use
the select element to create a dropdown menu.
- Each
option inside the select tag has a value attribute.
- Use
the selected attribute in an option tag to set the default selection.
4. Form
Groups and Inline Forms
Form groups and inline forms
enhance the layout and readability of forms.
Form
Groups:
Form groups organize related
inputs into logical sections for better user experience.
HTML
Syntax:
<div>
<label
for="username">Username:</label>
<input type="text"
id="username" name="username">
</div>
<div>
<label
for="password">Password:</label>
<input type="password"
id="password" name="password">
</div>
Inline
Forms:
Inline forms arrange inputs and labels
horizontally in a single line.
HTML
Syntax:
<form>
<label
for="email">Email:</label>
<input type="email"
id="email" name="email">
<label
for="password">Password:</label>
<input type="password"
id="password" name="password">
<button type="submit">Submit</button>
</form>
