需要帮助inArray

Question

您好，我具有以下功能，只有在选中其他两个复选框之一时，才需要使它返回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."   
);  

Answer 2

让我们尝试成为通用的...

$.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."   
);

那么你可以像这样使用它

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

Answer 3

您的问题有点不清楚。 我认为您的意思是，如果选中它并且该元素不在数组中，则它应该返回false（显示消息）。

$.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."   
);
