在这种情况下，我试图调用shoppingClickHandler(buyItem)期望它运行子switch语句以分配feature为buyItem.
但是我返回了错误Uncaught ReferenceError: buyItem is not defined。
我应该只向函数发送字符串吗？
function shoppingClickHandler(feature){
var msg;
var itemIdentifier = $(this).parent().attr('class');
switch(feature) {
case buyItem: msg = "You bought Item #" + itemIdentifier;
break;
case tryItem: msg = "You tried Item #" + itemIdentifier + " on";
break;
case suggestItem: msg = "You suggested Item #" + itemIdentifier;
break;
case giftItem: msg = "You gifted Item #" + itemIdentifier;
break;
case add_to_wishlist: msg = "You added Item #" + itemIdentifier + " to your wishlist";
break;
}
makeEntry(msg);
}
//Buy button test
$('.buy').click(function(){
shoppingClickHandler(buyItem);
})
//Try button test
$('.try').click(function(){
})
//Suggest button test
$('.suggest').click(function(){
})
//Gifting button test
$('.gift').click(function(){
})
//Add to wisthlist test
$('.add_to_wishlist').click(function(){
})
