Calling a function defined inside jQuery ready from outside of it

Question

My aspx page:-

Answer 1

Declare your function like this inside the document ready:

$(document).ready(function() {

    window.showMessage = function() {
        //...
    };

});

Then you should be able to call it from the other document like this:

window.opener.showMessage();

And because it's in the global scope, you can call it from within the main document just by calling

showMessage();
