Show HN: Tip Calculator – A simple project I made to learn jQuery
- codedestroyer 7y agoto reduce dom transversal you should assign selectors to variables. var tipBtn = $(".tip_btn"); then anytime you use tipBtn it has a saved reference to the dom node, if you repeat selectors they recalculate each use.
