Google Map API搜索过滤器

Question

我正在尝试过滤搜索框，土耳其只有3个区“Sarıyer”，“Beşiktaş”，“Şişli”。我在address_components中为long_name做了条件，但它无法正常工作。

我认为通过写这个条件，如果用户搜索这三个区域标记将在地图上设置。或者，如果用户搜索其他地方，则会显示弹出消息“您只能在这3个区域中搜索”

如何过滤搜索框

    var addCom1 = place.address_components[0].long_name;
    var addCom2 = place.address_components[1].long_name;
    var addCom3 = place.address_components[2].long_name;
    var addCom4 = place.address_components[3].long_name;
    var addCom5 = place.address_components[4].long_name;
    var addCom6 = place.address_components[5].long_name;

    if(addCom1 == "Şişli" || addCom1 == "Beşiktaş" || addCom1 == "Sarıyer" ||
    addCom2 == "Şişli" || addCom2 == "Beşiktaş" || addCom2 == "Sarıyer" ||
    addCom3 == "Şişli" || addCom3 == "Beşiktaş" || addCom3 == "Sarıyer" ||
    addCom4 == "Şişli" || addCom4 == "Beşiktaş" || addCom4 == "Sarıyer" ||
    addCom5 == "Şişli" || addCom5 == "Beşiktaş" || addCom5 == "Sarıyer" ||
    addCom6 == "Şişli" || addCom6 == "Beşiktaş" || addCom6 == "Sarıyer"){

     // Here i need set the marker

    }else{

     // Pop up messsage "You can only search these 3 districts"

    }
