Hey

I'd like to know how you can create a variable inside a function and then use it inside a different function. for example...

function getName()
{
var name=prompt("your name","")
}
function alertNamed()
{
alert(name)
}

Very simple example, and I know it doesn't work. I know it's because the name variable is local, but I know you can declare a variable and then use it inside other functions. It has something to do with return variablename or something similar...

I know it's a really basic quesiton but I've scoured the web and can't find an answer anywhere.

Help?

Cheers :-)

I see how you ment, but I'm not sure how you could do that.

I was hoping the 'global' bit would make the variable available to other functions, rather than just passing it.

I would be something like this, I think.

function alertNamed('name') {
alert(name);
}

but I'm not sure how to get the variable out of the first function, unless you call alertNamed(name) from inside the function .... but I was under the impression you don't want that???

You'll need to pass the value of the variable from one function over to the next.
No idea how to do it in JS though :-)

go on MSN and I'll annoy you about it.

Actually I think you may have misunderstood me, CJH...

What I need to do is create a variable inside a function and then pass it to another function. I'm sure it involves putting the variable name in the function name like: function rar(a_variable)
{
some stuff to decide the variable value then...

return a_variable
}
function use_the_variable_I_created(a_variable)


I'm sure it's something along those lines. I know I'm not maiing myself crystal clear though...

Nope, global doesn't work.

Lana - Making it global would just compromise what I need it for as it needs to be made on the call of a function.

I think ... *THINK* (not 100% sure) that you just add the word global to the beginning of the variable.

function getName() {
global var name = prompt("your name","")
}

Not totally sure but I would imagine you have to make the variable global, instead of being local to the method it is in.
Are they going to be within the same bit of code?

why not declare the variable before the methods and see if that works.

...and I know I used the phrase "I know" a lot in the last post ;-)
