[解决办法]
<script type= "text/javascript ">
function GetWeekday()
{
var weekday = new Array( "星期日 ", "星期一 ", "星期二 ", "星期三 ", "星期四 ", "星期五 ", "星期六 ");
var arrInput = document.getElementById( "t1 ").value.split( "- ");
if (arrInput.length < 3)
alert ( "error input ");
else
{
var d = new Date(arrInput[0], arrInput[1] - 1, arrInput[2]);
document.getElementById( "t2 ").value = weekday[d.getDay()];
}
}
</script>
<input type= "text " id= "t1 ">
<input type= "button " value= "go " onclick= "javascript:GetWeekday(); ">
<input type= "text " id= "t2 ">
[解决办法]
验证格式的函数没写
<script type= "text/javascript ">
function GetWeekday()
{
var arrInput = document.getElementById( "t1 ").value.split( "- ");
var d = new Date(arrInput[0], arrInput[1] - 1, arrInput[2]);
document.getElementById( "t2 ").value = "星期 "+ "日一二三四五六 ".charAt(d.getDay());
}
</script>
<input type= "text " id= "t1 ">
<input type= "button " value= "go " onclick= "javascript:GetWeekday(); ">
<input type= "text " id= "t2 ">
[解决办法]
<body> 格式为：2007/04/16
<input id= "txt " type= "text " onblur= "a() "> </br>
<input id= "txt1 " type= "text " value= " " >
<script language= "javascript ">
function a(){
var wek=new Array(7);
wek[0]= "星期日 ";
wek[1]= "星期一 ";
wek[2]= "星期二 ";
wek[3]= "星期三 ";
wek[4]= "星期四 ";
wek[5]= "星期五 ";
wek[6]= "星期六 ";
var txt=document.getElementById( "txt ");
var txt1=document.getElementById( "txt1 ");
var txt_value=txt.value;
alert(txt_value);
ind=(new Date(txt_value)).getDay();
txt1.value=wek[ind];
}
</script>
</body>

常用公历日期处理程序
"星期 " + "日一二三四五六 ".charAt(date.getDay());
