How to define web form submission (submit) in JS_javascript skills

The example in this article describes the method of defining web form submission (submit) in JS. Share it with everyone for your reference. The details are as follows:

This code means that when the web form is submitted, it is not submitted to the specified page, but executes a specific function

<script>
function saveInfo() {
 localStorage.setItem("name",$("#name").val());
}
</script>
<form id=register onSubmit="return saveInfo()">
 <label for="name">Name:</label>
 <input type=text name=name id=name>
 <input type=submit value=save>
</form>

I hope this article will be helpful to everyone’s JavaScript programming design.
