I am new to this Javascript
I want to design a webpapge using javascript which would find the square root of number using prompt dialog box from user.
I had written code as below but cannot get number through prompt.
How to get number through prompt function in java script
<script>
function myFunction()
{
var x;

var x=prompt("Enter number for square root","enter number");

if (x!=null)
{
x="Square root of " + x;
document.getElementById("demo").innerHTML=Math.sqrt(x);
}
}
</script>

Thanks a lot in advance

x="Square root of " + x;
document.getElementById("demo").innerHTML=Math.sqrt(x);

Didn't you see you have written text into X before getting sqrt of it? obviously this will fail...
