Hello! Just started learning javascript:
anyway just messing around trying to make a program where you enter a value into each of the two prompt boxes and the multiplied value of the two is show. I've got this:
function showprompt()
{
r=prompt("Enter first number:","");
if(r!=null && r!="")
{
x=r;
}
{
r2=prompt("Enter second number","");
if(r2!=null && r2!="")
{
y=r2
}
{
document.write(x*y);
}
}
}
So, it works. But the button (I use a button in the html
<button type="button" onclick="showprompt()">Hello!</button>
) Dissapears. Also any optimisation of the code would be cool to see, but make that seperate to the solution as to how to make the button not dissapear!!
Any help greatly appreciated!
