Text replace

rakeshs312

I have a text box andit will accept only time in the format 00:00(maximum value can be 12:59) . If user enter any of the value greater than this that part only needs to become 00. i have the code like this,but it will change the whole value to 00:00 . In the greater than conditions, what i have to write .

function ValidateTimeControl(s, e) {
var isValid = true;
if (e.value != null) {
if (e.value.substring(0, 1).trim() == "" || e.value.substring(1, 2).trim() == "" || e.value.substring(3, 4).trim() == "" || e.value.substring(3, 4).trim() == "") {
isValid = false;
}
else {
var hours = parseInt(e.value.substring(0, 2), 10);
var minutes = parseInt(e.value.substring(3, 5), 10);

        if (hours > 12) {alert(hours)
            isValid = false;
            
        }

        if (minutes > 59) {
            isValid = false;
        }
    }
}
else {
    isValid = false;
}

if (!isValid) {
    e.value = '00:00';
    
}

}

Thanks Rks

You need to rewrite the text value with the hours or minutes set to zero. Something like:

else {
var hours = parseInt(e.value.substring(0, 2), 10);
var minutes = parseInt(e.value.substring(3, 5), 10);

if (hours > 12) {
    alert(hours)
    hours = 0;
}
if (minutes > 59) {
    minutes = 0;

}
// I'm not sure about this but you can probably figure out the exact statement
e.value = hours.toString() + ":" + minutes.toString();

}

One of these days I'm going to think of a really clever signature.

Thanks for the reply . i Found a solution like this

function ValidateTimeControl(s, e) {
var isValidHour = true;
var isValidMin = true;
var hours, minutes;
if (e.value != null) {
if (e.value.substring(0, 1).trim() == "" || e.value.substring(1, 2).trim() == "" ) {
isValidHour = false;
}
if (e.value.substring(3, 4).trim() == "" || e.value.substring(3, 4).trim() == "") {
isValidMin = false;
}
else {
hours = parseInt(e.value.substring(0, 2), 10);
minutes = parseInt(e.value.substring(3, 5), 10);

        if (hours > 12) {alert(hours)
            isValidHour = false;
            
        }

        if (minutes > 59) {
            isValidMin = false;
            
        }
    }
}
else {
    isValidHour = false;
    isValidMin = false;
}

if (isValidHour == false && isValidMin == false) {
    e.value = '00:00';
} else if (isValidHour == false) {
    e.value = e.value.replace(hours, '00');
} else if (isValidMin == false) {
    e.value = e.value.replace(minutes, '00');
}

}
