HTMLInputElement: showPicker() method
The HTMLInputElement.showPicker()
method displays the browser picker for an input
element.
This is the same picker that would normally be displayed when the element is selected, but can be triggered from a button press or other user interaction.
Commonly browsers implement it for inputs of these types: "date"
, "month"
, "week"
, "time"
, "datetime-local"
, "color"
, or "file"
.
It can also be prepopulated with items from a <datalist>
element or autocomplete
attribute.
More generally, this method should ideally display the picker for any input element on the platform that has a picker.
Syntax
showPicker()
Parameters
None.
Return value
None (undefined
).
Exceptions
InvalidStateError
DOMException
-
Thrown if the element is not mutable, meaning that the user cannot modify it and/or that it cannot be automatically prefilled.
NotAllowedError
DOMException
-
Thrown if not explicitly triggered by a user action such as a touch gesture or mouse click (the picker requires Transient activation).
SecurityError
DOMException
-
Thrown if called in a cross-origin iframe, except for file and color pickers (exempt for historical reasons).
Security
Transient user activation is required. The user has to interact with the page or a UI element in order for this feature to work.
Examples
Feature Detection
The code below shows how to check if showPicker()
is supported:
if ("showPicker" in HTMLInputElement.prototype) {
// showPicker() is supported.
}
Normal input pickers
This example shows how this feature can be used for color
and file
input pickers.
Note: Pickers for date
, datetime-local
, month
, time
, week
are launched in the same way.
They cannot be shown here because live examples run in a cross-origin frame, and would cause a SecurityError
HTML
<p>
<input type="color" />
<button id="color">Show the color picker</button>
</p>
<p>
<input type="file" />
<button id="file">Show the file picker</button>
</p>
JavaScript
The code simply gets the previous element of the selected button and calls showPicker()
on it.
document.querySelectorAll("button").forEach((button) => {
button.addEventListener("click", (event) => {
const input = event.srcElement.previousElementSibling;
try {
input.showPicker();
} catch (error) {
window.alert(error);
}
});
});
Result
Click the button next to each input type to show its picker.
showPicker() for a datalist input
showPicker()
can launch the picker for a list of options defined in a <datalist>
.
First we define a <datalist>
in HTML consisting of a number of internet browsers, an input of type text
that uses it, and a button.
<datalist id="browsers">
<option value="Chrome"></option>
<option value="Firefox"></option>
<option value="Opera"></option>
<option value="Safari"></option>
<option value="Microsoft Edge"></option>
</datalist>
<input type="text" list="browsers" />
<button>Select browser</button>
The code below adds an event listener that calls showPicker()
when the button is clicked.
const button = document.querySelector("button");
const browserInput = document.querySelector("input");
button.addEventListener("click", () => {
try {
browserInput.showPicker();
} catch (error) {
// Fall back to another picker mechanism
}
});
showPicker() for autocomplete
showPicker()
can launch a picker for an autocomplete
input.
Here we define an input that takes an autocomplete option of "name".
<input autocomplete="name" /> <button>Show autocomplete options</button>
The code below shows the picker for the input when the button is clicked.
const button = document.querySelector("button");
const browserInput = document.querySelector("input");
button.addEventListener("click", () => {
try {
browserInput.showPicker();
} catch (error) {
// Fall back to another picker mechanism
}
});
