如何将事件侦听器添加到一行中的多个元素

问题描述：

示例1

Element1.addEventListener ("input", function() {
this function does stuff 
});

示例2

Element1 && Element2.addEventListener("input", function() {
this function does stuff
});

语法上可能不正确，但是有没有办法我可以在同一时间(同一行)为两个元素提供相同的Dom方法，而不必将它们分开书写?

it might not be correct grammatically, but is there a way i can give two elements the same Dom method at the same time (same line) instead of having to write them apart?

答

好吧，如果您有一个包含元素的数组，则可以这样做:

Well, if you have an array with the elements you could do:

let elementsArray = document.querySelectorAll("whatever");

elementsArray.forEach(function(elem) {
    elem.addEventListener("input", function() {
        //this function does stuff
    });
});
