JavaScript日期，今天9.29，它显示8.2

<script language="javascript">
function printdate(){
    var now=new Date();
    var year=now.getYear();
    var month=now.getMonth();
    var day=now.getDay();
var hour=now.getHours();
var min=now.getMinutes();
var sec=now.getSeconds();
var timeStr=""+year+"年";
timeStr=timeStr+month+"月";
timeStr=timeStr+day+"日 ";
timeStr+=hour;
timeStr+=((min <10)?":0":":")+min;
timeStr+=((sec <10)?":0":":")+sec;
document.clock_form.clock_text.value=timeStr;
clockId=setTimeout("printdate()",1000);

}
</script>


这段代码有什么错误吗？为什么今天是8.29，它却显示是8月2日呢？

月是从0开始的~·所以timeStr=timeStr+month+1+"月";把它再加1就成了

HTML code:

<script language="javascript">
function printdate(){
var now=new Date();
var year=now.getYear();
var month=now.getMonth();
var day=now.getDay();
var hour=now.getHours();
var min=now.getMinutes();
var sec=now.getSeconds();
var timeStr=""+year+"年";
timeStr=timeStr+month+"月";
timeStr=timeStr+day+&q
