Thevalue attribute is a string that contains the current value of the text entered into the text field. You can retrieve this using theHTMLInputElementvalue property in JavaScript.

let theText = myTextInput.value;

If no validation constraints are in place for the input (seeValidation for more details), the value may be an empty string ("").

In addition to theglobal attributes and the attributes that operate on all<input> elements regardless of their type, text inputs support the following attributes.

The values of the list attribute is theid of a<datalist> element located in the same document. The<datalist> provides a list of predefined values to suggest to the user for this input. Any values in the list that are not compatible with thetype are not included in the suggested options. The values provided are suggestions, not requirements: users can select from this predefined list or provide a different value.

The maximum string length (measured inUTF-16 code units) that the user can enter into thetext input. This must be an integer value of 0 or higher. If nomaxlength is specified, or an invalid value is specified, thetext input has no maximum length. This value must also be greater than or equal to the value ofminlength.

The input will failconstraint validation if the length of the text value of the field is greater thanmaxlengthUTF-16 code units long. Constraint validation is only applied when the value is changed by the user.

The minimum string length (measured inUTF-16 code units) that the user can enter into thetext input. This must be a non-negative integer value smaller than or equal to the value specified bymaxlength. If nominlength is specified, or an invalid value is specified, thetext input has no minimum length.

The input will failconstraint validation if the length of the text entered into the field is fewer thanminlengthUTF-16 code units long. Constraint validation is only applied when the value is changed by the user.

Thepattern attribute, when specified, is a regular expression that the input'svalue must match for the value to passconstraint validation. It must be a valid JavaScript regular expression, as used by theRegExp type, and as documented in ourguide on regular expressions; the'u' flag is specified when compiling the regular expression so that the pattern is treated as a sequence of Unicode code points, instead of asASCII. No forward slashes should be specified around the pattern text.

If the specified pattern is not specified or is invalid, no regular expression is applied and this attribute is ignored completely.

SeeSpecifying a pattern for further details and an example.

Theplaceholder attribute is a string that provides a brief hint to the user as to what kind of information is expected in the field. It should be a word or short phrase that demonstrates the expected type of data, rather than an explanatory message. The textmust not include carriage returns or line feeds.

If the control's content has one directionality (LTR orRTL) but needs to present the placeholder in the opposite directionality, you can use Unicode bidirectional algorithm formatting characters to override directionality within the placeholder; seeHow to use Unicode controls for bidi text for more information.

A Boolean attribute which, if present, means this field cannot be edited by the user. Itsvalue can, however, still be changed by JavaScript code directly setting theHTMLInputElementvalue property.

Thesize attribute is a numeric value indicating how many characters wide the input field should be. The value must be a number greater than zero, and the default value is 20. Since character widths vary, this may or may not be exact and should not be relied upon to be so; the resulting input may be narrower or wider than the specified number of characters, depending on the characters and the font (font settings in use).

This doesnot set a limit on how many characters the user can enter into the field. It only specifies approximately how many can be seen at a time. To set an upper limit on the length of the input data, use themaxlength attribute.

Thespellcheck global attribute is used to indicate whether to enable spell-checking for an element. It can be used on any editable content, but here we consider specifics related to the use ofspellcheck on<input> elements. The permitted values forspellcheck are:

false

Disable spell-checking for this element.

true

Enable spell-checking for this element.

"" (empty string) or no value

Follow the element's default behavior for spell-checking. This may be based upon a parent'sspellcheck setting or other factors.

An input field can have spell-checking enabled if it doesn't have thereadonly attribute set and is not disabled.

The value returned by readingspellcheck may not reflect the actual state of spell-checking within a control, if theuser agent's preferences override the setting.

<input> elements of typetext create basic, single-line inputs. You should use them anywhere you want the user to enter a single-line value and there isn't a more specific input type available for collecting that value (for example, if it's adate,URL,email, orsearch term, you've got better options available).

<form>  <div>    <label for="uname">Choose a username: </label>    <input type="text" name="name" />  </div>  <div>    <button>Submit</button>  </div></form>

This renders like so:

When submitted, the data name/value pair sent to the server will bename=Chris (if "Chris" was entered as the input value before submission). You must remember to includename attribute on the<input> element, otherwise the text field's value won't be included with the submitted data.

You can provide a useful placeholder inside your text input that can provide a hint as to what to enter by including using theplaceholder attribute. Look at the following example:

<form>  <div>    <label for="uname">Choose a username: </label>    <input      type="text"           name="name"      placeholder="Lower case, all one word" />  </div>  <div>    <button>Submit</button>  </div></form>

You can see how the placeholder is rendered below:

The placeholder is typically rendered in a lighter color than the element's foreground color, and automatically vanishes when the user begins to enter text into the field (or whenever the field has a value set programmatically by setting itsvalue attribute).

The physical size of the input box can be controlled using thesize attribute. With it, you can specify the number of characters the text input can display at a time. This affects the width of the element, letting you specify the width in terms of characters rather than pixels. In this example, for instance, the input is 30 characters wide:

<form>  <div>    <label for="uname">Choose a username: </label>    <input      type="text"           name="name"      placeholder="Lower case, all one word"      size="30" />  </div>  <div>    <button>Submit</button>  </div></form>

<input> elements of typetext have no automatic validation applied to them (since a basic text input needs to be capable of accepting any arbitrary string), but there are some client-side validation options available, which we'll discuss below.

There are useful pseudo-classes available for styling form elements to help the user see when their values are valid or invalid. These are:valid and:invalid. In this section, we'll use the following CSS, which will place a check (tick) mark next to inputs containing valid values, and a cross (X) next to inputs containing invalid values.

div {  margin-bottom: 10px;  position: relative;}input + span {  padding-right: 30px;}input:invalid + span::after {  position: absolute;  content: "✖";  padding-left: 5px;}input:valid + span::after {  position: absolute;  content: "✓";  padding-left: 5px;}

The technique also requires a<span> element to be placed after the form element, which acts as a holder for the icons. This was necessary because some input types on some browsers don't display icons placed directly after them very well.

You can use therequired attribute as an easy way of making entering a value required before form submission is allowed:

<form>  <div>    <label for="uname">Choose a username: </label>    <input type="text" name="name" required />    <span></span>  </div>  <div>    <button>Submit</button>  </div></form>

div {  margin-bottom: 10px;  position: relative;}input + span {  padding-right: 30px;}input:invalid + span::after {  position: absolute;  content: "✖";  padding-left: 5px;}input:valid + span::after {  position: absolute;  content: "✓";  padding-left: 5px;}

This renders like so:

If you try to submit the form with no search term entered into it, the browser will show an error message.

You can specify a minimum length (in characters) for the entered value using theminlength attribute; similarly, usemaxlength to set the maximum length of the entered value, in characters.

The example below requires that the entered value be 4–8 characters in length.

<form>  <div>    <label for="uname">Choose a username: </label>    <input      type="text"           name="name"      required      size="10"      placeholder="Username"      minlength="4"      maxlength="8" />    <span></span>  </div>  <div>    <button>Submit</button>  </div></form>

div {  margin-bottom: 10px;  position: relative;}input + span {  padding-right: 30px;}input:invalid + span::after {  position: absolute;  content: "✖";  padding-left: 5px;}input:valid + span::after {  position: absolute;  content: "✓";  padding-left: 5px;}

This renders like so:

If you try to submit the form with less than 4 characters, you'll be given an appropriate error message (which differs between browsers). If you try to enter more than 8 characters, the browser won't let you.

You can use thepattern attribute to specify a regular expression that the inputted value must match in order to be considered valid (seeValidating against a regular expression for a crash course on using regular expressions to validate inputs).

The example below restricts the value to 4-8 characters and requires that it contain only lower-case letters.

<form>  <div>    <label for="uname">Choose a username: </label>    <input      type="text"           name="name"      required      size="45"      pattern="[a-z]{4,8}" />    <span></span>    <p>Usernames must be lowercase and 4-8 characters in length.</p>  </div>  <div>    <button>Submit</button>  </div></form>

div {  margin-bottom: 10px;  position: relative;}p {  font-size: 80%;  color: #999;}input + span {  padding-right: 30px;}input:invalid + span::after {  position: absolute;  content: "✖";  padding-left: 5px;}input:valid + span::after {  position: absolute;  content: "✓";  padding-left: 5px;}

This renders like so:
