javascript 在多个元素上监听事件触发器

Posted 2021-05-03

const EL = document.querySelectorAll(".class"); // or #id or [attribute='att_name']

for (let i = 0; i < EL.length; i++) { // get the total number of elements selected and cycle through
  EL[i].addEventListener("event_type", function); // add event listener based on event type and the function to run or call
}
