Trouble with getElementsByClassName not targeting several divs at once

<a id="backgroundenamel_realbutton_powderblue"
 href="javascript:set_radio('radio_bgenamel_powderblue');" 
 class="radio-picture-enamel" style="background-color: #97b4d2;"
 onclick="document.getElementsByClassName('cx00ringbuilder_topinsidecolor_img')[0].style.backgroundColor='#97b4d2';">&nbsp;</a>

I am looking for a solution to modify the color of multiple divs using the code snippet above. I understand that I need to convert [0] to an array in order to achieve this, but I'm not sure how to do it. Any assistance on this matter would be greatly appreciated.

Answer №1

When trying to set a value for multiple objects simultaneously, it is essential to iterate through each object individually:

let items = document.getElementsByClassName('cx00ringbuilder_topinsidecolor_img');
for (let j = 0; j < items.length; j++) {
  items[j].style.backgroundColor='#97b4d2';
}
