jquery - Double quotes in Jquery

Question

I have read several posts regarding usinq quotes in jQuery and have not been able to form my own query. I have to check a span tag for a particular string. The string i am searching for is: role="alert" (it has double quotes around the word alert.

$("span:contains('role="alert"')").each(function() {        
        alert($(this).text());
    });

Can someone provide a query for this?
