How to call a function in javascript using onclick of a link

My code(Of course, not working): --HTML-- <a onclick="return putOnMap(this)">Purple Frog</a> --JAVASCRIPT-- function putOnMap(obj){ let name = obj.getAttribute('data-name'); for (let i = 0; i<locations.length; i++) { if(name == locations[i].name){ putOnMapUtil(locations[i].lat, locations[i].lng); alert(name); } } } I have tried href="#" also, but that also hasn't worked!

preventDefault() cancels the redirect <a href="#" onclick="putOnMap(event, this)"></a> function putOnMap(event, dom) { //code event.preventDefault(); }

When I just have an alert("hello") inside your function, clicking on the link calls the function. Have you checked the console for error messages?

Ya, It's working. Sorry to disturb. And my code is this now, can I eliminate href="#"? <a href="#" onclick="putOnMap(this)" data-name="Purple Frog">Purple Frog</a>
