如何从JS数组提取icon类名并添加到HTML的a元素中
Quick Tips to Connect Your Array to DOM Elements
Hey there! Glad you’ve already managed to log each icon value and the corresponding <a> elements—you’re already making great progress 😊
Here are some targeted hints to move forward:
- First, make sure you have a collection of all your
<a>elements (like usingdocument.querySelectorAll('ul li a')). Double-check that the length of this collection matches yourlistarray (both should be 5 items). - Both
forloops andArray.prototype.forEach()work perfectly here! If you go withforEach, you can use its second parameter (the index) to link the array item to the right<a>element. For aforloop, just use the loop index to access both the array object and the DOM element. - The key action you need is to add the icon class to each
<a>. Look into the DOM element’sclassList.add()method—it’s a clean way to add multiple classes at once. (Alternatively, you can useclassName, butclassListis more flexible for adding/removing classes later.) - Don’t forget to set the
aria-hidden="true"attribute on each<a>element. ThesetAttribute()method on DOM elements will let you do this easily.
Try focusing on linking each array index to the corresponding <a> element first, then applying those two properties one by one. You’ve got this!
