Javascript new random number everytime function is run

Question

I simply set up JSFiddle wrong, I'm new to Javascript and JSFiddle. Please forgive me.

When I open my app I want a random number appear. And I want a new random number to appear everytime I call the function. But so far I get the same number over and over again.

    function number(){
        var number= Math.floor(Math.random() * 230) + 90;
        document.getElementById("div").innerHTML = number;
    }

JSFiddle: http://jsfiddle.net/e6VFQ/3/

That code should work. Can you supply a fiddle that shows it not working? — Strikeskids, Jul 12 '14 at 20:36
Sry typo, should be `.innerHTML` that's what I wrote in the actuall code. — Carl, Jul 12 '14 at 20:41
You set up the jsfiddle wrong. Set the second dropdown on the left to "no wrap". http://jsfiddle.net/e6VFQ/4/ — JJJ, Jul 12 '14 at 20:44

@Juhana You're right. I had no idea the problem was in JSFiddle. — Carl, Jul 12 '14 at 20:50

Here's the quick fiddle : http://jsfiddle.net/hepc4/

No major changes though. Changed the way to show number, just to prove that the random numbers are properly getting generated.

js

function number(){
        var number= Math.floor(Math.random() * 230) + 90;
        document.getElementById("no").value= number;
    }

html

<input type="text" id="no"/>
<input type="button" onclick="number()" value="Generate Rnd No"/>

Its working just fine.

Here's a working fiddle:

You don't get anything in your div because the "content" property applies only to :before and :after pseudo elements. You should use innerText:

document.getElementById("div").innerText = number;
