HTML Input Types

This chapter describes the different types for the HTML element.

HTML Input Types

Here are the different input types you can use in HTML:

Tip: The default value of the type attribute is «text».

Input Type Text

defines a single-line text input field:

Example

This is how the HTML code above will be displayed in a browser:

Input Type Password

defines a password field:

Example

This is how the HTML code above will be displayed in a browser:

The characters in a password field are masked (shown as asterisks or circles).

Input Type Submit

defines a button for submitting form data to a form-handler.

The form-handler is typically a server page with a script for processing input data.

The form-handler is specified in the form’s action attribute:

Example

This is how the HTML code above will be displayed in a browser:

If you omit the submit button’s value attribute, the button will get a default text:

Example

Input Type Reset

defines a reset button that will reset all form values to their default values:

Example

This is how the HTML code above will be displayed in a browser:

If you change the input values and then click the «Reset» button, the form-data will be reset to the default values.

Input Type Radio

defines a radio button.

Radio buttons let a user select ONLY ONE of a limited number of choices:

Example

Choose your favorite Web language:

This is how the HTML code above will be displayed in a browser:

Input Type Checkbox

defines a checkbox.

Checkboxes let a user select ZERO or MORE options of a limited number of choices.

Example

This is how the HTML code above will be displayed in a browser:

I have a bike
I have a car
I have a boat

Input Type Button

defines a button:

Example

This is how the HTML code above will be displayed in a browser:

Input Type Color

The is used for input fields that should contain a color.

Depending on browser support, a color picker can show up in the input field.

Example

Input Type Date

The is used for input fields that should contain a date.

Depending on browser support, a date picker can show up in the input field.

Example

You can also use the min and max attributes to add restrictions to dates:

Example

Input Type Datetime-local

The specifies a date and time input field, with no time zone.

Depending on browser support, a date picker can show up in the input field.

Example

Input Type Email

The is used for input fields that should contain an e-mail address.

Depending on browser support, the e-mail address can be automatically validated when submitted.

Some smartphones recognize the email type, and add «.com» to the keyboard to match email input.

Example

Input Type Image

The defines an image as a submit button.

The path to the image is specified in the src attribute.

Example

Input Type File

The defines a file-select field and a «Browse» button for file uploads.

Example

Input Type Hidden

The defines a hidden input field (not visible to a user).

A hidden field lets web developers include data that cannot be seen or modified by users when a form is submitted.

A hidden field often stores what database record that needs to be updated when the form is submitted.

Note: While the value is not displayed to the user in the page’s content, it is visible (and can be edited) using any browser’s developer tools or «View Source» functionality. Do not use hidden inputs as a form of security!

Example

Input Type Month

The allows the user to select a month and year.

Depending on browser support, a date picker can show up in the input field.

Example

Input Type Number

The defines a numeric input field.

You can also set restrictions on what numbers are accepted.

The following example displays a numeric input field, where you can enter a value from 1 to 5:

Example

Input Restrictions

Here is a list of some common input restrictions:

Attribute	Description
checked	Specifies that an input field should be pre-selected when the page loads (for type=»checkbox» or type=»radio»)
disabled	Specifies that an input field should be disabled
max	Specifies the maximum value for an input field
maxlength	Specifies the maximum number of character for an input field
min	Specifies the minimum value for an input field
pattern	Specifies a regular expression to check the input value against
readonly	Specifies that an input field is read only (cannot be changed)
required	Specifies that an input field is required (must be filled out)
size	Specifies the width (in characters) of an input field
step	Specifies the legal number intervals for an input field
value	Specifies the default value for an input field

You will learn more about input restrictions in the next chapter.

The following example displays a numeric input field, where you can enter a value from 0 to 100, in steps of 10. The default value is 30:

Example

Input Type Range

The defines a control for entering a number whose exact value is not important (like a slider control). Default range is 0 to 100. However, you can set restrictions on what numbers are accepted with the min , max , and step attributes:

Example

Input Type Search

The is used for search fields (a search field behaves like a regular text field).

Example

Input Type Tel

The is used for input fields that should contain a telephone number.

Example

Input Type Time

The allows the user to select a time (no time zone).

Depending on browser support, a time picker can show up in the input field.

Example

Example

Input Type Week

The allows the user to select a week and year.

Depending on browser support, a date picker can show up in the input field.

How to use the HTML5 range input type

Before the introduction of HTML5, thinking about having a range slider on a webpage was equivalent of a crime. You needed a bunch of custom javascript code and still it didn’t work well on all devices.

However, HTML5 brought with it numerous new attributes and features that added the flavor that HTML missed for ages. Not many would have expected something like the range element to make its entrance with HTML5, but once it did, hardly any have raised any concerns with its working. Creating anything close to the sliding range element takes tons of lines of coding in JavaScript, but the same can be achieved with just a single element in HTML5. How often do you hear that something could be done better in HTML than JavaScript?

As the name suggests, the most common use of the slider input is when we know the lowest and the highest inputs that can be given as a response. For instance, if we are developing a website that only permits users in the age group 18-40. We can have the birth year as a sliding input range with the lowest value being 1986 and the highest being 1998. The slider input is a highly intuitive user interface that projects itself as an alternative to a plain textbox input or a drop-down with fixed values.

The range input is best when you have calculations associated with it. The flexibility of sliding the controls and seeing the result ’live’ is unmatchable.

How to create input sliding range element in HTML?

Here is the sample code for creating the input range element:

input name="weight" type="range" min="100" max="500" step="10" /> 

Here are the key attributes:

• min (The lowest accepted value in the range)
• max (The highest accepted value in the range)
• step (The increment/decrement step value default is 1)
• value (The starting or default value of the slider)

Displaying the current value

The default range element will only display the current position of the slider and the user has to guess the exact value. So in order to avoid the guesswork, you have to use one of the alternatives to display the current value. Here is a mostly HTML solution. (it uses Javascript in the attribute though)

A jQuery Solution to Display values for all range input elements

A more reusable solution would be to create a jquery snippet that handles the change event for all range input elements. Here is the code:

Negative & decimal values in the range input

Yes, you can have negative and decimal values in the range input see below for some examples:
