How do I run two or more functions when using 'onclick' JavaScript?

JavascriptWeb DevelopmentObject Oriented Programming

Let’s first set a button −

<button type="submit" onclick="callTwoOtherFunctions()"> Call </button>

Above, we have set a function under “onclick” to call two other functions −

function callTwoOtherFunctions(){
   fun1();
   fun2();
}

In this way, work around the fun1() and fun2() as in the complete code below −

Example

 Live Demo

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<button type="submit" onclick="callTwoOtherFunctions()"> Call
</button>
<script>
   function callTwoOtherFunctions(){
      fun1();
      fun2();
   }
   function fun1(){
      console.log("Function1()")
   }
   function fun2(){
      console.log("Function2()")
   }
</script>
</body>
</html>

To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.

This will produce the following output −

When you click on the Call button, you will get the following output. The snapshot is as follows −
