How do I make this random?

 I'm creating this game where you can pick a number between 1 and 10, but if someone guesses the right number, they'll always know it. How do I make it so that it will choose a different number everytime?

Here's the code:

Code:
 
<script type="text/javascript">
//pick a number between 1 and 10
var x=prompt("Enter a number between 1 and 10:","");
try
{
if(x>10)
{
throw "Err1";
}
else if(x<0)
{
throw "Err2";
}
else if(isNaN(x))
{
throw "Err3";
}
else if(x<4 && x>0)
{
throw "Err5";
}
else if(x>=5 && x<6)
{
throw "Err4";
}
else if(x>5 && x<11)
{
throw "Err6";
}
}
catch(er)
{
if(er=="Err1")
{
alert("Sorry, that's to high");
}
if(er=="Err2")
{
alert("Sorry, that's to low");
}
if(er=="Err3")
{
alert("Error! The value is not a number");
}
if(er=="Err5")
{
alert("Try again");
}
if(er=="Err4")
{
alert("good job!");
}
if(er=="Err6")
{
alert("Try again");
}
}
</script>

 Google is awesome.

Code:
 

Math.round(Math.random()*9+1)


You could probably find a better solution than that somewhere on Google, but that is what I could find.

Code:
 
<script type="javascript">

$("td:contains('Display emoticons in your post')").append("<br /><input type='checkbox' onclick='Dice_Is(this.checked)'> Enable Attack?");

function Dice_Is(really){
if(really==true){
document.forms['posting'].onsubmit=function(){
document.forms['posting'].post.value+="\n\n\Your Attack did [b]"+Math.floor(Math.random()*30)+"[/b] Damage!";
}
}
}
</script>


This is what i use which is fairly similar.
Its Javascript. But you could take out parts which arent needed.
The code basically allows the member to use the option of using the Random feature, and after they have posted the number comes up inbetween the text either side 'Your attack did' & 'damage!'

Code:
 
Math.floor(Math.random()*30)

Change the Number to the maximum number.

 The basic formula for getting a range is Math.random()*(max-min)+min. And, if you want a whole number, us Math.floor, Math.round, etc. to round it.

 Fission.. you don't need a minimum number unless you want it from 10-20, Also the code which i posted is already Whole Numbers, no decimals etc.

 I want to know who's right. All I want is place to put part of a code that makes it do a random number between 1 and 10.

Fission
 
Code:
 
Math.round(Math.random()*9+1)


Where would I put this?

 They're both right, just Fission's example allows the range to be between y and x, not 1 and [x.

You can put that wherever you want.

 Fission's method is useless if you are going from 1 - another number.
However it is great for when you are trying to go from say number 5 to number 8.

My method just goes from number 1 - another number.

 Sorry for bumping this back...

None of these things are working for me. When ever I type in 5, it always says it's right, instead of picking a different number. Can someone give me the code I created, with the added part that will make it a random number each time?
