hi,
I have time validation for one input textfield.
this time, I am trying to check for more than one textfields. But my code does not work...
Would you please help me??
Thank you in advance
=============

<html>

<HEAD>

<SCRIPT LANGUAGE="JavaScript">

function IsValidTime() {
for (i = 0; i <= 3; i++)
{

var timeStrA = document.timeform.time +'i'.value;
var timeStr = timeStrA+'i';
var timePat = /^(\d{1,2}):(\d{2})?$/;

var matchArrayA= timeStr.match(timePat);
var matchArray = matchArrayA +'i';
if (matchArray == null) {
alert("Time is not in a valid format.");
return false;
}

var hour = matchArray[1];
var minute = matchArray[2];

if (hour < 0 || hour > 24) {
alert("Hour must be between 1 and 12. (or 0 and 23 for military time)");
return false;
}

if (minute<0 || minute > 59) {
alert ("Minute must be between 0 and 59.");
return false;
}
}
}

</script>
</HEAD>


<BODY>

<center>
<form name=timeform onSubmit="return IsValidTime()">

time1 <input type=text name="time"><br>
time2 <input type=text name="time1"><br>
time3 <input type=text name="time2"><br>
time4 <input type=text name="time3"><br>

<input type="submit" value="Submit" >
</form >
</center>

</body>
</html>

Change this:

Code: 
var timeStrA = document.timeform.time +'i'.value;

to this:

Code: 
var timeStrA = document.forms['timeform'].elements['time + 'i'].value;

Hope this helps,
Dan

if that doesn't help, try this:

Code: 
<html>

<HEAD>

<SCRIPT LANGUAGE="JavaScript">

function IsValidTime(f) {
    var theName = 'time';
    var els = f.elements;
    
    var timeStrA, timeStr, timePat, matchArrayA, matchArray, hour, minute;
    
    for ( var i = 0; i < els.length; i++ ) {
        if (els[i].name.indexOf(theName) > -1) {
            timeStrA = els[i].value;
            timePat = /^(\d){1,2}:(\d{2})?$/;
            
            matchArrayA = timeStrA.match( timePat );
            
            if (matchArrayA == null) {
                alert("Time is not in a valid format.");
                els[i].focus();
                return false;
            }
            
            hour = matchArrayA[1];
            minute = matchArrayA[2];
            
            if (hour < 0  || hour > 24) {
                alert("Hour must be between 1 and 12. (or 0 and 23 for military time)");
                els[i].focus();
                return false;
            }
            
            if (minute<0 || minute > 59) {
                alert ("Minute must be between 0 and 59.");
                els[i].focus();
                return false;
            }
        }
    }
}

and
var theName ='time' to var theName ='time0' to, Then

leave theName as time. it will check all fields with the string "time" somewhere in the name. so it will check fields with the following names:

time
time0
time1
time2

but it will not check:

submit
rdoSomething
tim
bob
