<form name="orario" method="post" action="">

<input type="text" name="hour" size="20">

<input type="text" name="dates" size="20">

<input type="submit" value="Invia" name="B1">

</form>
</body>

</html>
    I need one function javascript check date and time insert in the form.

    If date is same the date now and the hour is less two hours the hours now, the form is stopped.

    For example:

    hours now = 14:50

    date = 22/09/2008
    hours = 15:30 ===> KO

    date = 22/09/2008
    hours = 16:49 ===> KO

    date = 22/09/2008
    hours = 16:50 ===> OK

    Can you help me?
    kind regards
    viki

          * Date register is same at today;
          * Hours register is less two hours the now

          Do you understand?

              Create a new Date object which will default to the current date and time. Then you can compare by creating another Date object using the input.

                              Which part do you not understand? It shows how to create a Date object, it shows how you can set a date, and shows how to compare. OK, since you want to compare time, you will also need to set the time which you can do with setHours/setMinutes/setSeconds - see a full reference.

                                  OK, I try this but not working... :

                                  Code:
                                  <script language="javascript">
<!--

function controllo_data(stringa){
    	var espressione = /^[0-9]{2}\/[0-9]{2}\/[0-9]{4}$/;
    	  if (!espressione.test(stringa))
    	  {
        	return false;
    	  }
	  else{
             anno = parseInt(stringa.substr(6),10);
             mese = parseInt(stringa.substr(3, 2),10);
             giorno = parseInt(stringa.substr(0, 2),10);
        
	     var data=new Date(anno, mese-1, giorno);
               if(data.getFullYear()==anno && data.getMonth()+1==mese && data.getDate()==giorno){
            		return true;
        		}
	       else{
                 return false;
               }
    	   }
}
	
function confronta_data(data1)

{
	dataCorr = new Date();
	giorno = dataCorr.getDate();
	mese = dataCorr.getMonth();
	anno = dataCorr.getYear();
	data = anno+mese+giorno;
	
    	if(controllo_data(data1))
    	
    	{
		
          data1str = data1.substr(6)+data1.substr(3, 2)+data1.substr(0, 2);
			

	  if (data1str-data<0) 
	  
	  {
            	alert("Error Date");
          }
        }

else{
       alert("KO");
	   document.orario.ggInizio.focus();
	   return false;

                                      You forgot the time part. Add the user inputted hours and minutes to the Date object too. When comparing, you can add 2 hours to the now date using setHours().

                                          Hi Viki, u can do it very well in this way.

                                          [HTML]var usrDate = new Date(year,month ,day,hour*,min* ,sec*,milli* );[/HTML]

                                          This is a parameterized constructor which will return u a date object.
                                          Note: The args with * are optional one but it will be useful for u to create a date obj with user given hour and minutes. Any soubts post back i will try to help u out.

                                          Regards
                                          Ramanan Kalirajan
