在我的greasemonkey脚本中,我想检查GM值:用户名和密码是否设置,但是当我尝试以下代码时它会给我回错:

TypeError: GM_getValue(...) is undefined    
...f (GM_getValue ("username").length == 0 + GM_getValue ("password").length == 0 )

码:

if (GM_getValue ("username").length == 0 + GM_getValue ("password").length == 0 ){
var username = $('input[name=username]');
var password = $('input[name=password]');

//Username en Password in Firefox zetten met GM_setValue
$(".button").click(function(){

GM_setValue ("username", username.val() );
GM_setValue ("password", password.val() );

});
}
