需要幫助inArray

Question

嗨我有以下功能，我需要使其僅返回false時，其他兩個複選框之一被選中。

$.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

你的意思是這樣的嗎？

$.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." 
); 

Answer 2

讓我們試着成爲一個小的通用...

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

，那麼你可以使用它像

rules: { 
    Country : { 
     ReutersNA : $("#IQBAS, #IQPRE").is(":checked") 
    } 
} 

Answer 3

你的問題有點不清楚。我認爲你的意思是它應該返回false（顯示消息），如果它被選中並且該元素不在數組中。

$.validator.addMethod( 
"ReutersNA", 
function(value, element) { 
    var selectedCountry = $("#Country").val(); 
    var NorthAmerica = new Array("USA","CAN","MEX"); 
    // Valid (true) if neither checked, or element is found in array. 
    return !$("#IQBAS, #IQPRE").is(":checked") || $.inArray(selectedCountry,NorthAmerica) > -1); 
}, 
"Cannot select Reuters News outside of North America." 
);
