<form> / <input> autocomplete Attribute

 

The autocomplete attribute specifies whether a form or input field should have autocomplete on or off.

 

When autocomplete is on, the browser automatically complete values based on values that the user has entered before.

 

Tip: It is possible to have autocomplete "on" for the form, and "off" for specific input fields, or vice versa.

 

Note: The autocomplete attribute works with <form> and the following <input> types: text, search, url, tel, email, password, datepickers, range, and color.

 

Example

 

An HTML form with autocomplete on (and off for one input field):

<form action="demo_form.asp" autocomplete="on">
  First name:<input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  E-mail: <input type="email" name="email" autocomplete="off"><br>
  <input type="submit">
</form> 

 

Tip: In some browsers you may need to activate the autocomplete function for this to work.

 

<form> novalidate Attribute

 

The novalidate attribute is a boolean attribute.

 

When present, it specifies that the form-data (input) should not be validated when submitted.

Example

 

Indicates that the form is not to be validated on submit:

<form action="demo_form.asp" novalidate>
  E-mail: <input type="email" name="user_email">
  <input type="submit">
</form> 

 

<input> autofocus Attribute

 

The autofocus attribute is a boolean attribute.

 

When present, it specifies that an <input> element should automatically get focus when the page loads.

Example

 

Let the "First name" input field automatically get focus when the page loads:

First name:<input type="text" name="fname" autofocus>

 

<input> form Attribute

 

The form attribute specifies one or more forms an <input> element belongs to.

 

Tip: To refer to more than one form, use a space-separated list of form ids.

Example

 

An input field located outside the HTML form (but still a part of the form):

<form action="demo_form.asp" id="form1">
  First name: <input type="text" name="fname"><br>
  <input type="submit" value="Submit">
</form>

Last name: <input type="text" name="lname" form="form1">

 

<input> formaction Attribute

 

The formaction attribute specifies the URL of a file that will process the input control when the form is submitted.

 

The formaction attribute overrides the action attribute of the <form> element.

 

Note: The formaction attribute is used with type="submit" and type="image".

Example

 

An HTML form with two submit buttons, with different actions:

<form action="demo_form.asp">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <input type="submit" value="Submit"><br>
  <input type="submit" formaction="demo_admin.asp"
  value="Submit as admin">
</form> 

 

<input> formenctype Attribute

 

The formenctype attribute specifies how the form-data should be encoded when submitting it to the server (only for forms with method="post")

 

The formenctype attribute overrides the enctype attribute of the <form> element.

 

Note: The formenctype attribute is used with type="submit" and type="image".

Example

 

Send form-data that is default encoded (the first submit button), and encoded as "multipart/form-data" (the second submit button):

<form action="demo_post_enctype.asp" method="post">
  First name: <input type="text" name="fname"><br>
  <input type="submit" value="Submit">
  <input type="submit" formenctype="multipart/form-data"
  value="Submit as Multipart/form-data">
</form> 

 

<input> formmethod Attribute

 

The formmethod attribute defines the HTTP method for sending form-data to the action URL.

 

The formmethod attribute overrides the method attribute of the <form> element.

 

Note: The formmethod attribute can be used with type="submit" and type="image".

Example

 

The second submit button overrides the HTTP method of the form:

<form action="demo_form.asp" method="get">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <input type="submit" value="Submit">
  <input type="submit" formmethod="post" formaction="demo_post.asp"
  value="Submit using POST">
</form> 

 

<input> formnovalidate Attribute

 

The novalidate attribute is a boolean attribute.

 

When present, it specifies that the <input> element should not be validated when submitted.

 

The formnovalidate attribute overrides the novalidate attribute of the <form> element.

 

Note: The formnovalidate attribute can be used with type="submit".

Example

 

A form with two submit buttons (with and without validation):

<form action="demo_form.asp">
  E-mail: <input type="email" name="userid"><br>
  <input type="submit" value="Submit"><br>
  <input type="submit" formnovalidate value="Submit without validation">
</form> 

 

<input> formtarget Attribute

 

The formtarget attribute specifies a name or a keyword that indicates where to display the response that is received after submitting the form.

 

The formtarget attribute overrides the target attribute of the <form> element.

 

Note: The formtarget attribute can be used with type="submit" and type="image".

Example

 

A form with two submit buttons, with different target windows:

<form action="demo_form.asp">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <input type="submit" value="Submit as normal">
  <input type="submit" formtarget="_blank"
  value="Submit to a new window">
</form> 

<input> height and width Attributes

 

The height and width attributes specify the height and width of an <input> element.

 

Note: The height and width attributes are only used with <input type="image">.

 

Tip: Always specify both the height and width attributes for images. If height and width are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the images load).

Example

 

Define an image as the submit button, with height and width attributes:

<input type="image" src="img_submit.gif" alt="Submit" width="48" height="48"> 

 

<input> list Attribute

 

The list attribute refers to a <datalist> element that contains pre-defined options for an <input> element.

Example

 

An <input> element with pre-defined values in a <datalist>:

<input list="browsers">

<datalist id="browsers">
  <option value="Internet Explorer">
  <option value="Firefox">
  <option value="Chrome">
  <option value="Opera">
  <option value="Safari">
</datalist> 

 

<input> min and max Attributes

 

The min and max attributes specify the minimum and maximum value for an <input> element.

 

Note: The min and max attributes works with the following input types: number, range, date, datetime, datetime-local, month, time and week.

Example

 

<input> elements with min and max values:

Enter a date before 1980-01-01:
<input type="date" name="bday" max="1979-12-31">

Enter a date after 2000-01-01:
<input type="date" name="bday" min="2000-01-02">

Quantity (between 1 and 5):
<input type="number" name="quantity" min="1" max="5">

 

<input> multiple Attribute

 

The multiple attribute is a boolean attribute.

 

When present, it specifies that the user is allowed to enter more than one value in the <input> element.

 

Note: The multiple attribute works with the following input types: email, and file.

Example

 

A file upload field that accepts multiple values:

Select images: <input type="file" name="img" multiple>

 

<input> pattern Attribute

 

The pattern attribute specifies a regular expression that the <input> element's value is checked against.

 

Note: The pattern attribute works with the following input types: text, search, url, tel, email, and password.

 

Tip: Use the global title attribute to describe the pattern to help the user.

Example

 

An input field that can contain only three letters (no numbers or special characters):

Country code: <input type="text" name="country_code" pattern="[A-Za-z]{3}" title="Three letter country code">

 

<input> placeholder Attribute

 

The placeholder attribute specifies a short hint that describes the expected value of an input field (e.g. a sample value or a short description of the expected format).

 

The hint is displayed in the input field when it is empty, and disappears when the field gets focus.

 

Note: The placeholder attribute works with the following input types: text, search, url, tel, email, and password.

Example

 

An input field with a placeholder text:

<input type="text" name="fname" placeholder="First name">

 

<input> required Attribute

 

The required attribute is a boolean attribute.

 

When present, it specifies that an input field must be filled out before submitting the form.

 

Note: The required attribute works with the following input types: text, search, url, tel, email, password, date pickers, number, checkbox, radio, and file.

Example

 

A required input field:

Username: <input type="text" name="usrname" required>

 

<input> step Attribute

 

The step attribute specifies the legal number intervals for an <input> element.

 

Example: if step="3", legal numbers could be -3, 0, 3, 6, etc.

 

Tip: The step attribute can be used together with the max and min attributes to create a range of legal values.

 

Note: The step attribute works with the following input types: number, range, date, datetime, datetime-local, month, time and week.

Example

 

An input field with a specified legal number intervals:

<input type="number" name="points" step="3">
