javascript读书札记
1.javascript对大小写敏感
2.JavaScript 会忽略多余的空格。所以可以在代码中添加适当的空格，使得代码的可读性更强，下面两行是等效的：
<html><body><script type="text/javascript">var d=new Date()var weekday=new Array(7)weekday[0]="星期日"weekday[1]="星期一"weekday[2]="星期二"weekday[3]="星期三"weekday[4]="星期四"weekday[5]="星期五"weekday[6]="星期六"document.write("今天是" + weekday[d.getDay()])</script></body></html>今天是星期三
