HTML5 Date Input with jQuery Fallback

HTML5 introduced a new date input type which allows a user to enter a date using a date picker.

<input id="date" type="date" value="2018-05-26">

This is what it looks like in Chrome:

However, not all browsers support this input type. In unsupported browsers, such as Internet Explorer, you will simply see a text input field.

In this post, I will show how you can detect if a browser supports the date input type and how you can fall back to using jQuery's date picker if it doesn't.

Checking if the browser supports date input:

The following code creates an input element and sets its type to date. If the browser does not support date input, this operation will not work and the input type will degrade to text.

var input = document.createElement("input");
input.setAttribute("type", "date");
if (input.type !== "date") {
    console.log("browser does not support date input");
}
Alternatively, use the Modernizr library, which makes it easy to detect the features that a browser supports:
if (!Modernizr.inputtypes.date) {
    console.log("browser does not support date input");
}
Falling back to jQuery's date picker:

The JSFiddle below shows how you would use jQuery's date picker if the browser does not support date input.
