How to Call Multiple JavaScript Functions in a Single click Event

Today I'm going to share some tips on how to call multiple JavaScript functions in a single click event.

Call Multiple JavaScript Functions in a Single click Event#

The first thing you'll need is a function which will contain the code necessary for executing all other functions when it's called upon. To do this, create an empty main function like so:

<script>  	
  function mainFunction() {  
     // Code goes here
  } 
</script> 

Once you have your main function set up, add each of your other individual functions inside of it using the following syntax:

<script>  	
  function mainFunction() {  
     childFunction1();
     childFunction2();
  } 
</script> 

Now all you need to do is attach an onclick event listener with our newly created main handler as its callback parameter - like so:

<button type="button" onclick="mainFunction()">
 Click Me
</button>

When clicked by a user, this button will now execute every single one of our individual JavaScript functions at once!
