A single function can be bound to multiple elements at once. For example, let's say we have the following function:
function func() {
console.log('!!!');
}
There are also two buttons:
<input id="button1" type="submit" value="button1">
<input id="button2" type="submit" value="button2">
Get references to these buttons into variables:
let button1 = document.querySelector('#button1');
let button2 = document.querySelector('#button2');
And now let's bind our function func
to both the first and the second button:
button1.addEventListener('click', func);
button2.addEventListener('click', func);
Given 5
paragraphs:
<p id="elem1">text</p>
<p id="elem2">text</p>
<p id="elem3">text</p>
<p id="elem4">text</p>
<p id="elem5">text</p>
Given the following function:
function func() {
console.log('message');
}
Bind this function to all 5
paragraphs.
