我的塞子无法启动

Question

In my code after click 'start ' I would like to see counting.

 var h = 0; var m = 0; var s = 0; function stoper() { s++; if (s == 60) { s = 0; m++; if (m == 60) { m = 0; h++; } } refresh(); } function refresh() { czas = h + ":" + m + ":" + s document.getElementById("czas").innerHTML = czas; } 

 <div id="czas"> <button onclick="setInterval(refresh,1000)">Start</button> </div> 

Answer 1

您应该致电stoper而不refresh ：像这样：

<button onclick="setInterval(stoper,1000)">Start</button>
