I have one variable in function, I want to access it from other function. I cannot define this variable out of function. I set the example code for review. http://jsfiddle.net/VC6Wq/1/
function one(){
var zero= 500;
}
function two(){
alert(zero)
}

I think this is what you are looking for.
function one() {
var zero = 500;
two(zero);
}
function two(a) {
alert(a);
}

You can make your variable underneath the window global variable, if this is in a browser. So like this:
function one() {
window.zero = 500;
}
function two() {
alert(window.zero)
}

Try like this
function one(){
var zero= 500;
return zero;
}
function two(){
var alt = one();
alert(alt);
}

You can declare that variable globally in Javascript and then use/modify/access as needed
function one()
{
myVar = 0;
alert(myVar);
two();
}
function two()
{
alert(myVar);
}

Try this :
function one(){
var zero = 500;
return zero;
}
function two(){
alert(one());
}
two();
Or define any other variable globally and assign it the value of the 'zero' :
var zero_2;
function one(){
var zero = 500;
var zero_2 = zero;
}
function two(){
alert(zero_2);
}
two();

I cannot define this variable out of function.
Since you cannot define the variable globally, one approach is simulate a global variable, attaching it to a DOM node, like this:
//note the notation 'data-'
<div id="node" data-zero='500'/>
To set the value:
// Store the value into data var within the div
$('#node').data('zero', value);
To get value:
var value = $('#node').data('zero');
alert(value);
Example: http://jsfiddle.net/VC6Wq/4/
two? Why you can not define it globally?data()like<div id="node" data-zero='myvalue'/> method. Then accessing to its value using$('#node').data('zero');
