Answer 1

懒得看你代码...标题的问题回答如下...
HelloWorld
vardiv=document.getElementsByTagName("div")[0];
div.setAttribute("id","yourdiv");
alert(document.getElementById("yourdiv").innerHTML);
                            

Answer 2

这是我根据我对你的意图的猜测得出的结论functiontitles(titleNum)
{
vartitleText=newArray("上午12点","上午1点","上午2点","上午3点","上午4点","上午5点","上午6点","上午7点","上午8点","上午9点","上午10点","上午11点","下午12点","下午1点","下午2点","下午3点","下午4点","下午5点","下午6点","下午7点","下午8点","下午9点","下午10点","下午11点");
document.write(''+titleText[titleNum]+'');
}
