Question

<script language="javascript"> 
function printdate(){
    var now=new Date();
    var year=now.getYear();
    var month=now.getMonth();
    var day=now.getDay();

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？

Answer 1

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

Answer 2

<script language="javascript">
function printdate(){

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+=((parseInt(min,10) <10)?":0":":")+min;
timeStr+=((parseInt(sec,10) <10)?":0":":")+sec;
document.clock_form.clock_text.value=timeStr;
clockId=setTimeout("printdate()",1000);}
</script> 

Answer 3

function printdate(){ 
    var now=new Date();
    var year=now.getFullYear(); 
    var month=now.getMonth()+1; 
    var day=now.getDate(); 
    var hour=now.getHours(); 
    var min=now.getMinutes(); 
    var sec=now.getSeconds(); 
    var timeStr=""+year+"年"; 
    timeStr=timeStr+month+"月";

    timeStr+=hour; 
    timeStr+=((min <10)?":0":":")+min; 
    timeStr+=((sec <10)?":0":":")+sec; 
    document.clock_form.clock_text.value=timeStr; 
    clockId=setTimeout("printdate()",1000); 
} 

Answer 4

写错<script language="javascript">
    function printdate(){
        var now=new Date();
        var year=now.getYear();
        var month=now.getMonth()+1;
        var day=now.getDate();
        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+=((parseInt(min,10) <10)?":0":":")+min;
        timeStr+=((parseInt(sec,10) <10)?":0":":")+sec;
        alert(timeStr)
        //document.clock_form.clock_text.value=timeStr;
        //clockId=setTimeout("printdate()",1000);    }
    printdate()
</script> 

Answer 5

1.getMonth()函数得到的时间少1
2.日用getDate()函数

Answer 6

getDay()是获取星期几，月份要加1
<script language="javascript"> 
function printdate(){ 
    var now=new Date(); 
    var year=now.getYear(); 
    var month=now.getMonth()+1; 
    var day=now.getDate(); 
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; 
alert(timeStr)
//document.clock_form.clock_text.value=timeStr; 
//clockId=setTimeout("printdate()",1000); } 
printdate();
</script>

Answer 8

getDay是星期几，今天是星期二，所以显示成2。改成getDate就是当月的的日期。
getMonth和楼上说的正确

Answer 9

有两个错误
第一：var month=now.getMonth();这里得到的月份应该要+1才行
第二：得到当前日不是  var day=now.getDay();
     应该是 var day = now.getDate();
