[jQuery] How to Reset a Form with jQuery

Clearing a form is something that you often need to do on a website, for example if you want to empty the form fields after submitting a form with Ajax.

Resetting a form using JavaScript is pretty straightforward, you can just call:

document.getElementById("#myform").reset();

But calling the reset() function on a jQuery object will not work. You’ll get an error saying TypeError: $(...).reset is not a function.

Why is that?

Well, the reset() function is a regular JavaScript function, not a jQuery function, and therefore won’t work on a jQuery object.

To get it to work, we need to extract the underlying DOM element from the jQuery object, and then we can call the function.

A jQuery object contains one or more DOM elements, and you can access the elements in it with normal array syntax, so this will work:

$("#myform")[0].reset();

Another way is to trigger the reset event by calling

$("#myform").trigger('reset');

Note that these methods will only reset the form fields to their initial values. It will not empty fields that has default values set on them.
