Do you have any idea why I cannot do like my way??? Many thanks in advance!! ( ^^ ) / Hiroki Kozai
lallous Paranoid (IV) Inmate From: Lebanon Insane since: May 2001	posted 05-23-2003 13:52 Hello Hiroki, I am fine, hope you're doing fine too. You cannot do -100<x<100 comparison in Javascript or any other high-level language I seen so far... Because that is an invalid syntax. To know what syntax is correct and what is not, you would better refer to a JavaScript manual/book Elias

Hi, guys. How are you?
Well, I have been under a lot of problems, I am afraid.
Especailly today....

My mission:

quote:
It returns the suare and the square root of an entered number. The number should be between -100 and 100. Othersise alert box says whether the number is too high or too low.

code:

<html>

<head>

<script type="text/javascript">

function cal()

 {

   if(-100<theForm.num.value<100)

    {

      theForm.sq.value=theForm.num.value*theForm.num.value

      theForm.root.value = Math.round(Math.sqrt(theForm.num.value)*100)/100;

    }

   else if(theForm.num.value>=100)

     {

       alert("Your number is too big!!!")

     }

    else

       {

        alert("Your number is too small!!!")

       }

   

  }



</script>

</head>



<body >



<form name="theForm">

<p>

X=

<input type="text" name="num" size="10">



<input type="button" value="Calculate" onClick="cal()">

<input type="reset" value="Reset">

</p>



<p>

X<sup>2<sup>=

<input type="text" name="sq">

</p>



<p>

Root X=

<input type="text" name="root">

</p>



</form>

</body>

</html>

Problem is alert box never pops up when I put in invalid number....
Would you see why???
Many thanks for sharing your time. Happy Thrusday.
Cya.

code:

if(-100<theForm.num.value<100)

change this to:

code:

x = parseInt(theForm.num.value);

if ( (x >= -100) && (x <= 100))

{

  alert('yeah');

}

else

{

  alert('number not between -100 and 100');

}

Hi, lallous! Good morning. How are you today???
Many many thank you for your help!!!!
It worked!

What I did is below:

code:

if((-100<theForm.num.value) && (theForm.num.value<100))

Instead of:

code:

if(-100<theForm.num.value<100)

It worked perfectly!

But can I ask something??? Do you have any idea why I cannot do like my way???
Many thanks in advance!! ( ^^ ) /

Hello Hiroki,

I am fine, hope you're doing fine too.
