How to access a JavaScript function parameter in another function

Question

I have two different JavaScript functions in same file, like this:

function functionOne(a)
{
   if(a)
   {
       return true;
   }
   else
   {
       return false;
   }
}

function functionTwo(b)
{
   //I want to access if condition parameter a here
}

I want to access functionOne if condition parameter a in functionTwo.

functionTwo(functionOne(a)) will pass the returned value of functionOne as functionTwo's parameter. — Patashu

i don't think it works... the parameter passed to functioneOne() is local to that function... it is better to declare a common vairable and check accordingly... — Pavan Kumar K

so i put it like as function functionTwo(b) { functionTwo(functionOne(a)) } — Bhagirath Singh

You can call function functionOne two time with different parameter like functionOne(a),functionOne(b). Why write another function ? — Hkachhia

The following are the two ways....

Option 1:

<script>
var newVar = "";
function functionOne(a)
{

if(a) { newVar = true; return true; } else { return false; } }

function functionTwo(b)
{
 //user newVar vairalbe to get the value
 //i want to access if condition parameter a here
}

Option 2:

<script>
function functionOne(a)
{
if(a)
{
    return a;
}
else
{
    return false;
}
}
function functionTwo(b)
{
//   call functionOne(a) to get the value;
//i want to access if condition parameter a here
}
</script>
