javascript - 需要有关 inArray 的帮助

Question

您好，我有以下函数，仅当选中其他两个复选框之一时，我才需要使其返回 false。

$.validator.addMethod(
"ReutersNA",
function(value, element) {
    var selectedCountry = $("#Country").val();
    var NorthAmerica = new Array("USA","CAN","MEX");
    if($.inArray(selectedCountry,NorthAmerica) > -1) {
    return true;
    } else return false;
    }, "Cannot select Reuters News outside of North America."
);

I need to add if($("#IQBAS, #IQPRE").is(":checked") && the above function = return true    

Answer 1

你的意思是这样的吗？

$.validator.addMethod(   
"ReutersNA",   
function(value, element) {   
    var selectedCountry = $("#Country").val();   
    var NorthAmerica = new Array("USA","CAN","MEX"); 
     return ($("#IQBAS, #IQPRE").is(":checked") && $.inArray(selectedCountry,NorthAmerica) > -1);
}, 
"Cannot select Reuters News outside of North America."   
);
