javascript - 如何在 lodash 中使用数组过滤条件来对抗对象？

Question

如何在lodash中过滤object ageist another object？但是条件对象是数组..

var form = { type: ['xyz', 'abc'], name: 'pre-1' }

var items = [
 { type: 'xyz', name: 'pre-1' },
 { type: 'abc', name: 'pre-1' }, 
 { type: 'xyz', name: 'pre-2' }, 
]

const results = lodash.filter(items, form);

结果应该是xyz和abc:

results = [{ type: 'xyz', name: 'pre-1' }, { type: 'abc', name: 'pre-1' }]

我可以使用 filter 方法做些什么吗？

好吧，您可以在 lodash 中使用自定义过滤器方法。尝试以下:

var form = { type: ['xyz', 'abc'], name: 'pre-1' }

var items = [
 { type: 'xyz', name: 'pre-1' },
 { type: 'abc', name: 'pre-1' }, 
 { type: 'xyz', name: 'pre-2' }, 
]

let filtered = _.filter(items, (item)=>{
    return form.type.indexOf(item.type) >= 0 && form.name == item.name
});

console.log(filtered);
