switch statement in Jquery and List

Solution

You code doesn't work because the variables are scoped to the function `HotelQuery`. I think what you might want to do is return an object with properties from the function, and also use the unobtrusive JavaScript approach to bind an click event handler to the `<a>` element.

Something like

$(function() {
    $('a').click(function() {
        var hotel = HotelQuery('TetrisHotel');

        alert(hotel.name) // alerts 'Tetris Hotel'
    });
});

function HotelQuery(HotelName) {
    var strHotelName;
    var strHotelDesc;
    var strHotelPrice;
    var strHotelRoomType;

    switch (HotelName) { 
        case 'TimelessHotel': 
            strHotelName = 'Timeless Hotel';
            strHotelDesc = 'Hotel Description Timeless Hotel';
            strHotelPrice = ['980.00', '1,300.00', '1,600.00', '1,500.00', '1,800.00', '300.00', '150.00', '200.00'];
            strHotelRoomType = ['Single Room', 'Delux Room','Twin Room', 'Matrimonial Room', 'Presidential Suites', 'Extra Bed', 'Free Breakfast', 'Extra Person']; 
            break; //end Timeless Hotel  

        case 'ParadiseInn': 
            strHotelName = 'Paradise Inn';
            strHotelDesc = 'Hotel Description Paradise Inn';
            strHotelPrice = ['980.00', '1,300.00', '1,600.00', '1,500.00', '1,800.00', '300.00', '150.00', '200.00'];
            strHotelRoomType = ['Single Room', 'Delux Room','Twin Room', 'Matrimonial Room', 'Presidential Suites', 'Extra Bed', 'Free Breakfast', 'Extra Person'];    
            break; //end Paradise Inn

        case 'TetrisHotel': 
            strHotelName = 'Tetris Hotel';
            strHotelDesc = 'Hotel Description Tetris Hotel';
            strHotelPrice = ['980.00', '1,300.00', '1,600.00', '1,500.00', '1,800.00', '300.00', '150.00', '200.00'];
            strHotelRoomType = ['Single Room', 'Delux Room','Twin Room', 'Matrimonial Room', 'Presidential Suites', 'Extra Bed', 'Free Breakfast', 'Extra Person'];  
            break; //end Tetris Hotel 

        case 'JamstoneInn': 
            strHotelName = 'Jamstone Inn';
            strHotelDesc = 'Hotel Description Jamstone Inn';
            strHotelPrice = ['980.00', '1,300.00', '1,600.00', '1,500.00', '1,800.00', '300.00', '150.00', '200.00'];
            strHotelRoomType = ['Single Room', 'Delux Room','Twin Room', 'Matrimonial Room', 'Presidential Suites', 'Extra Bed', 'Free Breakfast', 'Extra Person'];    
            break; //end Jamstone Inn 
    }
    return {
        name: strHotelName,
        desc: strHotelDesc,
        price: strHotelPrice,
        roomType: strHotelRoomType 
    }
};

Just noticed that you're also returning the same values other than the hotel name and description each time (you might have done this just as an example, I'm not sure). You could just assign all variables their value on declaration (or assign the values as properties of the returned object), other than the hotel name and description, which you could assign from the value of the argument for parameter `HotelName`. Something like

function hotelQuery(hotelName) {
    return {
        name: hotelName,
        desc: 'Hotel Desciption' + hotelName,
        // Keep prices as numbers and have a function to display them 
        // in the culture specific way. Numbers for prices will be easier to deal with
        price: [980, 1300, 1600, 1500, 1800, 300, 150, 200],
        roomType: ['Single Room', 'Delux Room','Twin Room', 'Matrimonial Room', 'Presidential Suites', 'Extra Bed', 'Free Breakfast', 'Extra Person']
    } 
}
