如何從輸入時間html標記獲取第二個值到JavaScript變量

Question

s1變量沒有獲得秒值，請在此處輸入代碼

 function fun() { time=document.getElementById("time").value; h1=time[0]; h2=time[1]; m1=time[3]; m2=time[4]; s1=time[6];// Not Working document.getElementById("print").value=h1+""+h2+""+":"+m1+""+m2+":"+s1; } setInterval(fun,1000); 

 <p>Time:<p> <input type="time" id="time" name="time" step="1"></input><br> <input type="text" id="print"></input> 

Answer 1

這是你想要的嗎？

 function fun() { time=document.getElementById("time").value; h1=time[0]; h2=time[1]; m1=time[3]; m2=time[4]; s1=time[6]; s2=time[7]; document.getElementById("print").value = h1+""+h2+""+":"+m1+""+m2+":"+s1+""+s2; } 

 <p>Time:</p><input type="time" id="time" name="time" step="1"></input><br> <input type="text" id="print"></input>
