Assume that
`elements` is a NodeList that matches given selector:js
const elements = document.querySelectorAll(...);You can loop over
`elements` by using one of the approach below:#1. Use the ES6 spread operator
js
[...elements].forEach(function(ele) {
...
});#2. Use the Array methods
js
// `Array.from` is not supported on IE
Array.from(elements).forEach(function(ele) {
...
});
// Or
[].forEach.call(elements, function(ele) {
...
});
// Or
[].slice.call(elements, 0).forEach(function(ele) {
...
});#3. Use the forEach method
If you don't have to support Internet Explorer, then use the
`forEach` method:js
elements.forEach(function(ele) {
...
});#See also
