javascript常用例子

1.判断是否为日期
//是否是日期格式 
function isDateString(sDate)
{ 
	var iaMonthDays =[31,28,31,30,31,30,31,31,30,31,30,31]
	var iaDate = new Array(3)
	var year, month, day
		
	if (arguments.length != 1) return false
	iaDate = sDate.toString().split("-")
	if (iaDate.length != 3) return false
	if (iaDate[1].length > 2 || iaDate[2].length > 2) return false
		
	year = parseFloat(iaDate[0])
	month = parseFloat(iaDate[1])
	day=parseFloat(iaDate[2])
		
	if (year < 1900 || year > 2100) return false
	if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) iaMonthDays[1]=29;
	if (month < 1 || month > 12) return false
	if (day < 1 || day > iaMonthDays[month - 1]) return false
	return true
	}


2.javascript中的提示确认对话框 
function rusure_agree()
{  
	question = confirm("是否确定批准该声请?")  
	if (question !="0")
	{
	document.v_AddVacationForm.action="v_ProcessVacation.do?vacation_id=<%=tv.getVacationId()%>";
	document.v_AddVacationForm.submit();
	} 
}


3.javascript提交action
(1)提交带form的action 
document.v_AddVacationForm.action="../../v_AddVacation.do";
   document.v_AddVacationForm.submit();

(2)提交不带form的action,可以说是个链接 
window.location.href="v_AddVacation.do";


4.html中的超链接提交 
<a style="cursor: pointer" onclick="check();" >submit</a>
