Example of anonymous function usage in JavaScript

This article illustrates the use of anonymous functions in JavaScript as an example. Share with you for your reference. The specific analysis is as follows:

Instead of giving a function a name, JS allows you to assign the body of a function to a related event or variable directly through function.

The JS code below sets an onclick event for the button, using anonymous functions

<form action="#">
<input type="button" value="Click Me" id="anonbutton" />
</form>
<script type="text/javascript">
var anonbutton = document.getElementById("anonbutton");
anonbutton.onclick = function() {
  alert("anonymous function called.");
}
</script>

I hope this article is helpful to you in javascript programming.
