我有以下问题。我喜欢根据fruits数组过滤这个fruitsCollection。 我希望结果是,例如:
filteredFruits1 [ all fruits with the
exception of those which are in
fruitsToCut array
]
示例:
var fruitsToCut = [ 'egzotic', 'other'],
fruitsCollection = [ {name: papaya, type: 'egzotic'},
{name: orange, type: 'citrus'},
{name: lemon, type: 'citrus'}
]
也许有一些下划线功能?
答案 0 :(得分:2)
在现代浏览器上,您可以使用原生filter
:
fruitsCollection.filter(function(fruit) {
return fruitsToCut.indexOf(fruit.type) === -1;
} );
否则,你可以用几乎相同的方式使用underscore filter:
_.filter( fruitsCollection, function(fruit) {
return !_.contains(fruitsToCut, fruit.type);
} );
此外,您的水果名称需要引用:
fruitsCollection = [ {name: 'papaya', type: 'egzotic'},
{name: 'orange', type: 'citrus'},
{name: 'lemon', type: 'citrus'}
];
