How to set value to global variable in javascript from html.?

Question

I have html page that takes input from user in textbox and when user clicks on "Connect" javascript is called and value is passed for system to connect, i am able to send the value to that function but cant use that value for any other function in that script, so i want to pass it to global vaiable so that it is accesible for the whole script.

Answer 1

Have you tried to declare the variable outside the function?

var outside = null;

function setoutside(value)

{

outside = value;

}

From your html page, you can now call <script>setouside('newvalue');</script>

The global value will now be 'newvalue', and can be used by other functions.
