javascript click on class code example

Example 1: javascript class click event

var elements = document.getElementsByClassName("classname");

var myFunction = function() {
    var attribute = this.getAttribute("data-myattribute");
    alert(attribute);
};

for (var i = 0; i < elements.length; i++) {
    elements[i].addEventListener('click', myFunction, false);
}

// If you have ES6 support you can replace your last line with:

    Array.from(elements).forEach(function(element) {
      element.addEventListener('click', myFunction);
    });

Example 2: click on div with class javascript

<!--In html:-->
<div class="myDiv with_this_class" > any text </div>
<script>
  var divClicked = document.querySelector('.myDiv.with_this_class').click();
</script>
