我想要在數字<10的狀況加一個0
<!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>定时器</title> <script type="text/javascript"> var attime; function clock(){ var time=new Date(); var SecondsAlt; if (parseInt(time.getSeconds()) <10){ SecondsAlt = "0"+time.getSeconds() }; else{ SecondsAlt = time.getSeconds() } attime=time.getHours()+":"+time.getMinutes()+":"+SecondsAlt; document.getElementById("clock").value = attime; } setInterval(clock,100) </script> </head> <body> <form> <input type="text" id="clock" size="50" /> </form> </body> </html>
請問我這樣寫,哪裡有bug,謝謝
目的:12:50:1 -> 12:50:01
