Lets see if I can explain it. I have an INPUT html element, and I has stored some value on it. This value is a javascript function name like this:

<input id="myinput" value="doSomething();" type="hidden">

In a javascript function I'm getting the variable this way:

var aFunction = document.getElementById('myinput');

If aFunction  is not null then I need to call the function stored on it, in other words, I need to call

"doSomething();"

. The problem is that the value of 'myinput' is variable and at this point I don't know it. I wonder if there is a way to do something like this in javascript. Thank you for any suggestion.
