JavaScript-da bitta ishlovchi ko'p elementlarga

Bitta funktsiyani bir vaqtning o'zida bir nechta elementlarga bog'lash mumkin. Misol uchun, quyidagi funktsiyamiz bor:

javascriptfunction func() {
  console.log('!!!');
}

Shuningdek, ikkita tugma mavjud:

html<input id="button1" type="submit" value="button1">
<input id="button2" type="submit" value="button2">

Ushbu tugmalarning havolalarini o'zgaruvchilarga olaylik:

javascriptlet button1 = document.querySelector('#button1');
let button2 = document.querySelector('#button2');

Endi func funktsiyamizni ham birinchi, ham ikkinchi tugmaga bog'laymiz:

javascriptbutton1.addEventListener('click', func);
button2.addEventListener('click', func);

html<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>

javascriptfunction func() {
  console.log('message');
}
