Posted By:Athira Sreejith       Posted Date: March 19, 2009    Points: 10    Category: Javascript    URL: http://www.dotnetspark.com  
 

This function is used to validate Date using Javascript in client side.

function isDate(dtStr){
 var daysInMonth = DaysArray(12)
 var pos1=dtStr.indexOf(dtCh)
 var pos2=dtStr.indexOf(dtCh,pos1+1)
 var strMonth=dtStr.substring(0,pos1)
 var strDay=dtStr.substring(pos1+1,pos2)
 var strYear=dtStr.substring(pos2+1)
 strYr=strYear
 if (strDay.charAt(0)=="0" && strDay.length>1) strDay=strDay.substring(1)
 if (strMonth.charAt(0)=="0" && strMonth.length>1) strMonth=strMonth.substring(1)
 for (var i = 1; i <= 3; i++) {
  if (strYr.charAt(0)=="0" && strYr.length>1) strYr=strYr.substring(1)
 }
 month=parseInt(strMonth)
 day=parseInt(strDay)
 year=parseInt(strYr)
 if (pos1==-1 || pos2==-1){
  alert("The date format should be : mm/dd/yyyy")
  return false
 }
 if (strMonth.length<1 || month<1 || month>12){
  alert("Please enter a valid month")
  return false
 }
 if (strDay.length<1 || day<1 || day>31 || (month==2 && day>daysInFebruary(year)) || day > daysInMonth[month]){
  alert("Please enter a valid day")
  return false
 }
 if (strYear.length != 4 || year==0 || yearmaxYear){
  alert("Please enter a valid 4 digit year between "+minYear+" and "+maxYear)
  return false
 }
 if (dtStr.indexOf(dtCh,pos2+1)!=-1 || isInteger(stripCharsInBag(dtStr, dtCh))==false){
  alert("Please enter a valid date")
  return false
 }
return true
}
