从一个函数调用变量到另一个

Question

I have a create person button, and some radio buttons where I can assign a gender to the person. Ie: Male or Female.

$('#BtnCreatePerson').click(function(e)
{   
var sPersonGender = $("#gender input[type='radio']:checked").val();
}

What do I do if I need to call the variable in another function in an external js file and place it in an if statement. Like

if (gender == Male && gender == Female)
{
   do something
}

UPDATE: I still can't get it to work. I've created a JSFIDDLE . It's a bit messy, i know.

Answer 1

Generally you would store the value outside of the function, possibly as a property of an object you have created, or the window object.

Person = {};

$('#BtnCreatePerson').click(function(e) {   
   Person.gender = $("#gender input[type='radio']:checked").val();
});

And in your other file:

if (Person) {
   if (Person.gender === "Male") {
       // some code...
   } 
}

Answer 2

Why Not?

if ($("#gender input[type='radio']:checked").val()== Male && 
$("#gender input[type='radio']:checked").val()== Female)
{
   do something
}

Also I think that's an OR, since they can't be both male AND female :p
