I Have 3 html files & 3 js files

index.html,rank.html,score.html

global.js,rank.js,score.js

In index.html I have included rank.html and score.html using iframe.

In global.js I have declare Var rank; & global.js included in rank.html & score.html.

I am updating the value of rank in rank.js and i want to access the updated value in score.js. In score.js I dont get the Updated value It gives UNDEFINED value.

I dont want to include rank.js in score.html so i created global.js & included in html file.

Here is my code,

Index.html

<html>
    <head>

    </head>
    <body>
<iframe src="../rank/rank.html" frameborder = "0" scrolling="no" width="50%" height = "100%"></iframe>
<iframe src="score.html" frameborder = "0" scrolling="no" width="50%" height = "100%"></iframe>

    </body>
</html>

global.js

var rank;

score.js

$(document).ready(
        function(){     


                    setInterval(dataupdate, 10000);


    });
function dataupdate() { 

alert(rank) 

};

rank.js

$(document).ready(
            function(){     


                        setInterval(dataupdate, 10000);


        });
    function dataupdate() { 

    rank = "first";

    };

    When you declare a global variable like you’ve done it gets created as a property of the window object, i.e window.rank. Your main window and the 2 iframes have separate window objects and therefore window.rank assigned from the main frame is not the same window.rank accessed from one of the iframes.

    For accessing the rank property of the main window object from inside an iframe, you can use parent.rank instead of window.rank
