从lodash

Question

我让它在代码段中工作但不在我的打字稿代码中。我得到了

  

属性colorId和sizeId在类型{}

上不存在

 const ids = [
        {
            "skuId": 693194,
            "sizeId": "12M",
            "colorId": "ROSE"
        },

            "colorId": "ROSE"
        },
        {

            "sizeId": "6M",
            "colorId": "GREEN"

     ]
     
     const sku = _.result(_.find(ids, function(sku) {
                  return sku.colorId === 'ROSE' && 
                    sku.sizeId === '14M';
                                    }), 'skuId');
                                    
                                    console.log(sku);

如果您正在使用打字稿和角度，请尝试使用：

# -*- coding: utf-8 -*-
import scrapy

from scrapy.spiders import CrawlSpider
from scrapy.spiders import Rule
from scrapy.linkextractors import Linkextractors

class MpuDivsSpider(CrawlSpider):
    name = 'mpu_divs'
    allowed_domains = ['www.capitalfm.com']
    start_urls = ['http://www.capitalfm.com/']

    rules = [

        Rule(LinkExtractor(allow=[r'/7-august-2017/\w*'])
        callback='parse_item',
        follow = True)
    ]

    def parse_item(self, response):
        print response.url

希望它可以帮到你

Answer 2

通过将id转换为Array

解决了这个问题

_.result(_.find(<Array<any>>ids, function(sku) {
              return sku.colorId === 'ROSE' && 
                sku.sizeId === '14M';
                                }), 'skuId');

                                console.log(sku);
