JavaScript 通过数组进行过滤，并且仅根据一个值的匹配返回

Question

我有一个对象数组，它们都有一个阶段键，我只想返回与特定阶段值匹配的对象，然后将其他几个键/值映射到最终返回中。这是我到目前为止所拥有的:

phaseToBlocks (toggle, phase) {
  this.phaseBlocks = this.$store.state.addresses.salesRepPhases
  return this.phaseBlocks
    .filter(fiber_phase === phase)
    // .map(({id, phase, name, min_number, max_number}) => ({id: id, phase: fiber_phase, name: name, min_number: min_number, max_number: max_number}))
}

当前不会过滤掉任何对象并返回原始对象数组。这是对象数组的片段:

[ { "fiber_phase": "101", "parsed_hash": "1bc7fb114ee10d7cb9cea10693d238b5", "min_number": 400, "max_number": 499, "sales_rep": "164", "id": "abd90d6b-28a8-2be6-d6c1-abd9007aef38", "name": "48TH ST E", "block_minimum": 400, "block_maximum": 498 }, { "fiber_phase": "101", "parsed_hash": "1bc7fb114ee10d7cb9cea10693d238b5", "min_number": 400, "max_number": 499, "sales_rep": "164", "id": "abd90d6b-28a8-2be6-d6c1-abd9007aef38", "name": "48TH ST E", "block_minimum": 401, "block_maximum": 499 }, { "fiber_phase": "103", "parsed_hash": "1e002ef82be950696f9053dc77b621cf", "min_number": 4700, "max_number": 4799, "sales_rep": "164", "id": "a1d58c9c-6ba7-ebc6-8a74-a1d5806e0bcf", "name": "11TH AVE S", "block_minimum": 4700, "block_maximum": 4798 }]

Answer 1

filter() 采用回调函数来检查条件并执行过滤:

return this.phaseBlocks
    .filter(item => item.phase === phase);
