Examples of anonymous function usage in JavaScript_javascript skills

The examples in this article describe the usage of anonymous functions in JavaScript. Share it with everyone for your reference. The specific analysis is as follows:

In JS, you don’t need to give the function a name. Instead, you can directly assign the function body to the relevant event or variable through the function when using it.

The following JS code sets an onclick event for the button, using an anonymous function

<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 will be helpful to everyone’s JavaScript programming design.
