Why I can not get the updated "cars" array in my new popped up window
Question
My index.html has a button( id="my-btn" ):
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>My INDEX PAGE</title>
</head>
<body>
<br><input type="button" id="my-btn" value="OPEN NEW WINDOW"/>
<script src="js/my.js"></script>
</body>
</html>
above page include my.js which handles button click event, when button clicked, a new browser window will be opened with a new page( test.html )
my.js:
$('#my-btn').click(function(){
window.open('test.html', 'testwindow');
});
The new page ( test.html ) opened/popped up in new browser window: test.html:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>TEST</title>
</head>
<body>
<div id="cars"></div>
<script src="js/jquery-1.5.1.js"></script>
<script src="js/mycar.js"></script>
<script src="js/test.js"></script>
</body>
</html>
In the new page, test.js is included which will call functions in MyTest and append the text of number of cars as the content of this pop-up page:
js/test.js
$(document).ready(function(){
MyTest.updateCars(); //MyTest is a function defined in mycar.js
var cars = MyTest.getCars();
$("#cars").append("<strong>number of cars: "+cars.length+"</strong>");
});
Function MyTest is defined in mycar.js:
js/mycar.js
var MyTest = function(){
var cars=[];
var updateCars=function(){
cars.push('car 1', 'car 2');
};
return{
updateCars: function(){
updateCars();
},
getCars: function(){
console.log(cars.length);
return cars;
}
};
}();
But, when the test.html page popped up in a new browswer window, the number of cars is always 0.
As you saw above I have called updateCars() function of mycar.js in test.js but the pop up window does not show the updated cars number , how can I get the updated cars(that's 2 cars, car1 and car2) in the new popped up window?
(I have jquery-1.5.1.js under "js/" directory)

hey i pasted your code in a page and it displayed
number of cars: 2
it seems to work are you just referencing the script wrong? have you tried the debugger on chrome or firebug?
