scopedThe input component is a wrapper to the HTML input element with custom styling and additional functionality. It accepts most of the same properties as the HTML input, but works great on desktop devices and integrates with the keyboard on mobile devices.
The input component is meant for text type inputs only, such as "text", "password", "email", "number", "search", "tel", and "url". It supports all standard text input events including keyup, keydown, keypress, and more. The default type is "text".
Labels should be used to describe the input. They can be used visually, and they will also be read out by screen readers when the user is focused on the input. This makes it easy for the user to understand the intent of the input. Input has several ways to assign a label:
label property: used for plaintext labelslabel slot: used for custom HTML labels (experimental)aria-label: used to provide a label for screen readers but adds no visible label
Labels will take up the width of their content by default. Developers can use the labelPlacement property to control how the label is placed relative to the control.
While plaintext labels should be passed in via the label property, if custom HTML is needed, it can be passed through the label slot instead.
Note that this feature is considered experimental because it relies on a simulated version of Web Component slots. As a result, the simulated behavior may not exactly match the native slot behavior.
If no visible label is needed, developers should still supply an aria-label so the input is accessible to screen readers.
Inputs offer two options for clearing the input based on how you interact with it. The first way is by adding the clearInput property which will show a clear button when the input has a value. The second way is the clearOnEdit property which will clear the input after it has been blurred and then typed in again. Inputs with a type set to "password" will have clearOnEdit enabled by default.
Material Design offers filled styles for an input. The fill property on the input can be set to either "solid" or "outline".
Since the fill styles visually defines the input container, inputs that use fill should not be used in ion-item.
Filled inputs can be used on iOS by setting Input's mode to md.
Helper & Error Text
Helper and error text can be used inside of an input with the helperText and errorText property. The error text will not be displayed unless the ion-invalid and ion-touched classes are added to the ion-input. This ensures errors are not shown before the user has a chance to enter data.
In Angular, this is done automatically through form validation. In JavaScript, React and Vue, the class needs to be manually added based on your own validation.
The input counter is text that displays under an input to notify the user of how many characters have been entered out of the total that the input will accept. When adding counter, the default behavior is to format the value that gets displayed as inputLength / maxLength. This behavior can be customized by passing in a formatter function to the counterFormatter property.
The counter and counterFormatter properties on ion-item were deprecated in Ionic 7 and should be used directly on ion-input instead.
Inputs with a counter add a border between the input and the counter, therefore they should not be placed inside of an ion-item which adds an additional border under the item. The ion-padding-start class can be added to align the counter inputs with inputs inside of items.
Developers can use the ionInput event to update the input value in response to user input such as a keypress. This is useful for filtering out invalid or unwanted characters.
When storing the value in a state variable, we recommend updating both the state variable and the ion-input component value. This ensures that the state variable and the ion-input component value remain in sync.
Input masks are expressions that constrain input to support valid input values. Ionic recommends using Maskito for input masking. Maskito is a lightweight, dependency-free library for masking input fields. It supports a wide range of masks, including phone numbers, credit cards, dates, and more.
To get started with Maskito, install the library:
npm install @maskito/core @maskito/{angular,react,vue}
The start and end slots can be used to place icons, buttons, or prefix/suffix text on either side of the input.
In most cases, Icon components placed in these slots should have aria-hidden="true". See the Icon accessibility docs for more information.
If slot content is meant to be interacted with, it should be wrapped in an interactive element such as a Button. This ensures that the content can be tabbed to.
Note that this feature is considered experimental because it relies on a simulated version of Web Component slots. As a result, the simulated behavior may not exactly match the native slot behavior.
Setting the color property changes the color palette for each input. On ios mode, this property changes the caret color. On md mode, this property changes the caret color and the highlight/underline color.
Input uses scoped encapsulation, which means it will automatically scope its CSS by appending each of the styles with an additional class at runtime. Overriding scoped selectors in CSS requires a higher specificity selector. Targeting the ion-input for customization will not work; therefore we recommend adding a class and customizing it that way.
A simpler input syntax was introduced in Ionic 7.0. This new syntax reduces the boilerplate required to setup an input, resolves accessibility issues, and improves the developer experience.
Developers can perform this migration one input at a time. While developers can continue using the legacy syntax, we recommend migrating as soon as possible.
Using the modern syntax involves three steps:
- Remove
ion-label and use the label property on ion-input instead. The placement of the label can be configured using the labelPlacement property on ion-input. - Move input-specific properties from
ion-item on to ion-input. This includes the counter, counterFormatter, fill, and shape properties. - Remove usages of the
helper and error slots on ion-item and use the helperText and errorText properties on ion-input instead.

Ionic uses heuristics to detect if an app is using the modern input syntax. In some instances, it may be preferable to continue using the legacy syntax. Developers can set the legacy property on ion-input to true to force that instance of the input to use the legacy syntax.

ionBlur | Emitted when the input loses focus. |
ionChange | The ionChange event is fired when the user modifies the input's value. Unlike the ionInput event, the ionChange event is only fired when changes are committed, not as the user types.
Depending on the way the users interacts with the element, the ionChange event fires at a different moment: - When the user commits the change explicitly (e.g. by selecting a date from a date picker for <ion-input type="date">, pressing the "Enter" key, etc.). - When the element loses focus after its value has changed: for elements where the user's interaction is typing. |
ionFocus | Emitted when the input has focus. |
ionInput | The ionInput event is fired each time the user modifies the input's value. Unlike the ionChange event, the ionInput event is fired for each alteration to the input's value. This typically happens for each keystroke as the user types.
For elements that accept text input (type=text, type=tel, etc.), the interface is InputEvent; for others, the interface is Event. If the input is cleared on edit, the type is null. |
| Description | Returns the native <input> element used under the hood. |
| Signature | getInputElement() => Promise<HTMLInputElement> |
| Description | Sets focus on the native input in ion-input. Use this method instead of the global input.focus().
Developers who wish to focus an input when a page enters should call setFocus() in the ionViewDidEnter() lifecycle method.
Developers who wish to focus an input when an overlay is presented should call setFocus after didPresent has resolved. |
| Signature | setFocus() => Promise<void> |
No CSS shadow parts available for this component.
