Question

I am trying to get first character from the clsName i.e. ‘+’ or ‘-‘ in variable n.
This works in IE 8 but in IE 7 I get ‘undefined’.
Please let me know how do I fix it.

var clsName = $(this).attr("class");
var n = $('.'+clsName).text()[0];
alert(n);

Answer 1

String[index] is not supported in IE7-. Use charAt instead:

var n = $('.'+clsName).text().charAt(0);
