单击另一个按钮时如何显示一个按钮？

Question

For example, if we have btn 1 and btn 2.

Is it possible (with the onclick event) to click on btn 1, and then btn 2 appears?

Answer 1

Yes .

Any element, including button elements, can have events set which trigger styling properties of other elements to change.

An Example:

 let get = document.querySelector.bind(document), btn1 = get("#btn1"), btn2 = get("#btn2"); btn1.addEventListener("click", function() { btn2.style.display = "initial"; }); 

 .hidden { display: none; } 

 <button id="btn1">Click Me</button> <button id="btn2" class="hidden" >I'm a button</button>
