The 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".
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.
The item counter is helper 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.
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 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.
The color to use from your application's color palette. Default options are: "primary", "secondary", "tertiary", "success", "warning", "danger", "light", "medium", and "dark". For more information on colors, see theming.
A regular expression that the value is checked against. The pattern must match the entire value, not just some subset. Use the title attribute to describe the pattern to help the user. This attribute applies when the value of the type attribute is "text", "search", "tel", "url", "email", "date", or "password", otherwise it is ignored. When the type attribute is "date", pattern will only be used in browsers that do not support the "date" input type natively. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date for more information.
Instructional text that shows before the input has a value. This property applies only when the type property is set to "email", "number", "password", "search", "tel", "text", or "url", otherwise it is ignored.
The initial size of the control. This value is in pixels unless the value of the type attribute is "text" or "password", in which case it is an integer number of characters. This attribute applies only when the type attribute is set to "text", "search", "tel", "url", "email", or "password", otherwise it is ignored.
