If else function

**m960** · 05-14-2012 05:43 AM

Hello, guys. I'm a new student in programming class. We're studying "if else functions" right now, and i've got a project to turn in soon. The objective is to be able to tell where i'm at, at a given time. Please look at my codes and help me in correcting it.

<html>
<head>
 Where is Mishaal? 
<title>Mishaal Locator</title>
<body>

<script type= "text/javascript">

var d= new Date() ;
var time= d.getHours() ;
var minute= d.getMinutes() ;

if (time<=7 && minute>=35)
{
document.write("Mishaal is in Fitness class");
}
else if (time>= 8 && minute>=15)
{
document.write(" Mishaal is in the hall");
}
if (time<=8 && minute>=20)
{
document.write(" Mishaal is in Arabic Class");
}
else if (time>=9 && minute>=40)
{
document.write(" Mishaal is in the hall");
}
if (time<=9 && minute>=50)
{
document.write(" Mishaal is in Biology Class ");
}
else if ( time>=11 && minute>=10)
{
document.write(" Mishaal is out for Lunch");
}
if (time<=11 && minute>=50)
document.write(" Mishaal is in Spanish Class");
{
else if (time>=13 && minute>=5)
document.write(" Mishaal is in the hall");
}
if (time<=13 && minute>=15)
document.write(" Mishaal is in Programming");
{
else (time>=14 && minute>=30)
document.write(" Mishaal's going home");
}

</script>
</body>
</html>

thank you for your time.

You probably want to keep saying "else if" instead of rotating every other statement.

Ex:

Code:

if (time<=7 && minute>=35)
{
document.write("<b>Mishaal is in Fitness class</b>");
}
else if (time>= 8 && minute>=15)
{
document.write("<b> Mishaal is in the hall</b>"); 
}
else if (time<=8 && minute>=20)
{
document.write("<b> Mishaal is in Arabic Class</b>");
}

Also, you want to put a catch all at the end to account for any time in between your classes.

Code:

else if (time<=13 && minute>=15)
document.write("<b> Mishaal is in Programming</b>"); 
{
else if (time>=14 && minute>=30)
document.write("<b> Mishaal's going home</b>");
} else {
document.write('<b>Mishaal is in between classes.</b>');
}

thank you for your help, i really appreciate it. If i may, i just have one more question to ask. If i were to do this schedule for two days, with different classes would this method work properly?

You'll have to implement another check to see what day of the week it is.

Do yourself a favor and preview all of your javascript in a syntax checker. There is one here: http://jslint.com/

It will most likely hurt your feelings at first. But it is great for someone learning the language. Make sure to read the instructions.
