Call multiple JavaScript functions in single onclick event

You might have a situation where you need to call multiple JavaScript functions in a single onclick event. So in this post, we are going to tackle the same situation.

There are two methods to to call multiple JavaScript functions :

1. Call the functions by separating them by “;”. for example: onclick=”funca();funcb();”
2. Wrap all functions in a new JavaScript function and call it.

First solution:

function a() {
    console.log("a");
}

function b() {
    console.log("b");
}

Then in HTML, you can call these functions as mentioned below:

<button>Click Me</button>

In the above example we have called two functions a() and b() by separating them “;”. This is very easy and there is no extra code in this approach.

Second solution:

function a() {
    console.log("a");
}

function b() {
    console.log("b");
}

function c() {
    a();
    b();
}

Then in HTML, you can call these functions as mentioned below:

<button>Click Me</button>

In this second approach, we have wrapped our functions in new function c(). You might have noticed that in this approach we have written extra code to achieve the same result.
