<html><head><script>function startTime(){var today=new Date()var h=today.getHours()var m=today.getMinutes()var s=today.getSeconds()// add a zero in front of numbers<10m=checkTime(m)s=checkTime(s)document.getElementById('txt').innerHTML=h+":"+m+":"+st=setTimeout('startTime()',500)}function checkTime(i){if (i<10)?? {i="0" + i}? return i}</script></head><body onload="startTime()"><div id="txt"></div></body></html>這段代碼中function checkTime(i){if (i<10) ?{i="0" + i}return i}這個循環是什么意思還有這個checkTime（i）代表著什么?。?
哪位大神能夠幫忙解決一下這個問題？
