Kevin H Posted March 28, 2019 Report Share Posted March 28, 2019 Hi all, I am trying to work with tabs and using the How to Create Tabs page on the w3 site below. I am unclear on one part. In the HTML code, what is the event parameter referring to in the onclick function. I've copied on of the relevant lines below. If someone could elaborate further it would be much appreciated. <button class="tablinks" onclick="openCity(event, 'London')">London</button> https://www.w3schools.com/howto/howto_js_tabs.asp Link to comment Share on other sites More sharing options...
