Javascript Array not working in IE7 and older versions but working in IE10

Javascript Array not working in IE7 and older versions but working in IE10 Here is my code which is working in IE10 but not working in IE7.

    number = "123";
    var j=0;
    alert(number[j]);

Please let me know how to call the variable values as single dimension array in older browsers.

Javascript Array not working in IE7

This is not an array “not working” – you have a string value here (the browser will convert it to one, because for numbers no such kind of access is defined), and are trying to access it’s single characters with a zero-based index.

Older IE simply don’t support this – so cast it to a string (implicitly/explicitly) and then use the charAt method of the String object instead .

(''+number)[j] should work in any browser, assuming that number is something that can be coerced to a String anyway.
