## Methods

<table class="standard-table">
  <tbody>
    <tr>
      <td>{{domxref("HTMLElement.blur()", "blur()")}}</td>
      <td>
        Removes focus from the input element; keystrokes will subsequently go
        nowhere.
      </td>
    </tr>
    <tr>
      <td>{{domxref("HTMLElement.click()", "click()")}}</td>
      <td>Simulates a click on the input element.</td>
    </tr>
    <tr>
      <td>{{domxref("HTMLElement.focus()", "focus()")}}</td>
      <td>
        Focuses on the input element; keystrokes will subsequently go to this
        element.
      </td>
    </tr>
    <tr>
      <td>
        {{domxref("HTMLInputElement.select()", "select()")}}
      </td>
      <td>
        Selects all the text in the input element, and focuses it so the user
        can subsequently replace all of its content.
      </td>
    </tr>
    <tr>
      <td>
        {{domxref("HTMLInputElement.setSelectionRange()", "setSelectionRange()")}}
      </td>
      <td>
        Selects a range of text in the input element (but does not focus it).
      </td>
    </tr>

    <tr>
      <td><code>setCustomValidity()</code></td>
      <td>
        Sets a custom validity message for the element. If this message is not
        the empty string, then the element is suffering from a custom validity
        error, and does not validate.
      </td>
    </tr>
    <tr>
      <td><code>checkValidity()</code></td>
      <td>
        Returns a {{jsxref("Boolean")}} that is <code>false</code> if the
        element is a candidate for constraint validation, and it does not
        satisfy its constraints. In this case, it also fires an
        {{event("invalid")}} event at the element. It returns
        <code>true</code> if the element is not a candidate for constraint
        validation, or if it satisfies its constraints.
      </td>
    </tr>
    <tr>
      <td><code>reportValidity()</code></td>
      <td>
        Runs the <code>checkValidity()</code> method, and if it returns false
        (for an invalid input or no pattern attribute provided), then it reports
        to the user that the input is invalid in the same manner as if you
        submitted a form.

- {{domxref("HTMLInputElement.stepDown()")}}

  - : Decrements the {{htmlattrxref("value","input")}} by ({{htmlattrxref("step","input")}} \* n), where n defaults to 1 if not specified. Throws an INVALID_STATE_ERR exception:

    - if the method is not applicable to for the current {{htmlattrxref("type","input")}} value,
    - if the element has no {{htmlattrxref("step","input")}} value,
    - if the {{htmlattrxref("value","input")}} cannot be converted to a number,
    - if the resulting value is above the {{htmlattrxref("max","input")}} or below the {{htmlattrxref("min","input")}}.

- {{domxref("HTMLInputElement.stepUp()")}}

  - : Increments the {{htmlattrxref("value","input")}} by ({{htmlattrxref("step","input")}} \* n), where n defaults to 1 if not specified. Throws an INVALID_STATE_ERR exception:

    - if the method is not applicable to for the current {{htmlattrxref("type","input")}} value.,
    - if the element has no {{htmlattrxref("step","input")}} value,
    - if the {{htmlattrxref("value","input")}} cannot be converted to a number,
    - if the resulting value is above the {{htmlattrxref("max","input")}} or below the {{htmlattrxref("min","input")}}.

- {{domxref("HTMLInputElement.mozSetFileArray()")}} {{non-standard_inline}}
  - : Sets the files selected on the input to the given array of {{domxref("File")}} objects. This is an alternative to `mozSetFileNameArray()` which can be used in frame scripts: a chrome script can [open files as File objects](/en-US/docs/Extensions/Using_the_DOM_File_API_in_chrome_code) and send them via [message manager](/en-US/Firefox/Multiprocess_Firefox/The_message_manager).
- {{domxref("HTMLInputElement.mozGetFileNameArray()")}} {{non-standard_inline}}
  - : Returns an array of all the file names from the input.
- {{domxref("HTMLInputElement.mozSetFileNameArray()")}} {{non-standard_inline}}
  - : Sets the filenames for the files selected on the input. Not for use in [frame scripts](/en-US/Firefox/Multiprocess_Firefox/Limitations_of_frame_scripts), because it accesses the file system.

## Events

Listen to these events using [`addEventListener()`](/en-US/docs/Web/API/EventTarget/addEventListener) or by assigning an event listener to the `oneventname` property of this interface:

- [`input`](/en-US/docs/Web/API/HTMLElement/input_event)
  - : Fires when the `value` of an {{HTMLElement("input")}}, {{HTMLElement("select")}}, or {{HTMLElement("textarea")}} element has been changed. Note that this is actually fired on the {{domxref("HTMLElement")}} interface and also applies to [`contenteditable`](/en-US/docs/Web/HTML/Global_attributes/contenteditable) elements, but we've listed it here because it is most commonly used with form input elements.
    Also available via the [`oninput`](/en-US/docs/Web/API/GlobalEventHandlers/oninput) event handler property.
- [`invalid`](/en-US/docs/Web/API/HTMLElement/invalid_event)
  - : Fired when an element does not satisfy its constraints during constraint validation.
    Also available via the [`oninvalid`](/en-US/docs/Web/API/GlobalEventHandlers/oninvalid) event handler property.
- [`search`](/en-US/docs/Web/API/HTMLInputElement/search_event)
  - : Fired when a search is initiated on an {{HTMLElement("input")}} of `type="search"`.
    Also available via the [`onsearch`](/en-US/docs/Web/API/GlobalEventHandlers/onsearch) event handler property.
