Ampersands in string constants

Do not forget, dear javascript-programmers, in string constants specify the ampersand as "& amp;", and not just as "&". For otherwise, the results will be very browser-dependent:

document.body.innerHTML = "http://example.org/get.php?test";
document.body.innerHTML + = "& ok";
document.body.innerHTML + = "& wonderful";

Result:

Firefox:	http://example.org/get.php?test&ok&wonderful
Chrome:	http://example.org/get.php?test&wonderful
IE:	http://example.org/get.php?test
