您的代码不起作用,因为变量的作用域是函数HotelQuery.我认为您可能想要做的是返回一个具有该函数属性的对象,并使用不显眼的JavaScript方法将click事件处理程序绑定到该<a>元素.
就像是
$(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
}
};
只是注意到你每次都返回除了酒店名称和描述之外的相同值(你可能只是作为一个例子,我不确定).您可以将所有变量的值分配给声明(或将值指定为返回对象的属性),而不是酒店名称和描述,您可以从参数的参数值中指定HotelName.就像是
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']
}
}
几个问题.
1)没有必要将函数放在内部$(document).ready,摆脱它.
2)每个案例陈述应该后跟一个break,而不是一个;.例如:
function HotelQuery(HotelName) {
switch (HotelName) {
case 'TetrisHotel':
// stuff goes here ...
break; //end Tetris Hotel
};
}
3)你的处理程序中alert不应该跟a ::onclick
alert: (strHotelName, strHotelDesc, strHotelPrice);
应该
alert(strHotelName, strHotelDesc, strHotelPrice);
此外,alert只需要一个参数,因此您需要将其分解:
alert(strHotelName); alert(strHotelDesc); alert(strHotelPrice);
3)你在假设strHotelName,strHotelDesc并且strHotelPrice在全球范围内,他们不是.
总而言之,您可能想尝试这样的事情:
