If I want Neighbourhood only I do that :

if($.inArray("neighbourhood", address) !== -1){
                    console.log(' neighbourhood only ');
                    result = address.neighbourhood;
                }

Generally I need only city but neighbourhood display too (This last is used for capital and big city).

if($.inArray("city", response) !== 0){
                    console.log(' city only ';
                    result = address.city;
                }

My function ($.inArray) or the condition (!== -1) seems wrong because even the object doesn't exist the condition return true and consider the condition

With this array object and these two condition the console display: neighbourhood only and city only (but 'city' doesn't exist)

this problem can be repeated with other key : suburb and town. if two or more key object exist inside array object there are a conflict and nothing display (using the same condition)

CodePudding user response：

$.inArray is for arrays, use in for objects

if("city" in adress){
    console.log(' city only ';
    result = address.city;
}
