let toggleForm = function() {
// code here
}
document.getElementById('one').addEventListener("click", toggleForm, false);
document.getElementById('two').addEventListener("click", toggleForm, false);
In toggleForm I'd like to know whether element one or two fired the event. How would you go about doing that?
Use e.target:
<button id = 'one'>One</button>
<button id = 'two'>Two</button>
<script>
var one = document.getElementById('one'),
two = document.getElementById('two');
let toggleForm = function(e) {
if (e.target === one) alert('One');
else alert('Two');
};
one.addEventListener("click", toggleForm, false);
two.addEventListener("click", toggleForm, false);
</script>
