Question

I have about 20 links with a specific class for links I want to target. If the 10th link is clicked, how can I get it’s index value (I need “10” to be returned)?

I am using plain JavaScript so no jQuery!

Answer 1

Loop throught the elements, example

function linkOnClick(el) {

    var elements = document.getElementsByClassName('className');
    for (var i = 0; i < elements.length; i++) {
        if (elements[i] == el) {
            alert(i); // index of element
        }
    }
}
