Form Name Variable?

[barkster]

Why doesn't this work

 

var f = document.form1;
function1 () {
   alert(f.tb1.value);
}
fuction2 () {
   alert(f.tb2.value);
}

 

but this does?

 

function1 () {
   f = document.form1;
   alert(f.tb1.value);
}
fuction2 () {
   f = document.form1;
   alert(f.tb2.value);
}

defining a variable inside of a function makes it available within that function.

defining a variable outside of a function makes it available within a function ONLY IF you pass that variable to the function (in the parenthesis after the function's name)
