javascript - Array.every 函数并未在 Object 的所有元素上运行

Question

我正在尝试使用以下代码在 temp1 内搜索是否有任何值具有字符串“processado”

let temp1 = [{
    "id":7089,
    "value":"R$ 50,00",
    "name":"Daiany Nascimento",
    "date":"18/03/2019",
    "type":"Cobrança",
    "status":{
        "status":"Paga",
        "icon":"paid"
    },
    "credit_release_date":"Não Processado",
    "credit_release_description":"— — — —"
}]

let b = []

temp1.forEach((a,index_a) => { 
Object.values(a).every((value,index,array) => {
    let expression = new RegExp("processado", "i") //expression to search
    if (typeof value == "object") {
      Object.values(value).every(valueOfObject => {    
        if (expression.test(valueOfObject)) {
          b.push(temp1[index_a])
          return false;
        } else {
          return true
        }
      })
    }
    else if (expression.test(value)){ 
      b.push(temp1[index_a])
      return false
    }
      else {
      return true
    }
  })
})

但是，数组 b 仍然为空。如果我尝试搜索字符串“Cobrança”，数组 b 就会被填充，正如它应该的那样。我认为，如果我尝试搜索存储在状态键键之后上的值，则会出现错误.

您需要在 if (typeof value == "object") 内返回 Object.values(value).every(valueOfObject....

let temp1 = [{"id":7089,"value":"R$ 50,00","name":"Daiany Nascimento","date":"18/03/2019","type":"Cobrança","status":{"status":"Paga","icon":"paid"},"credit_release_date":"Não Processado","credit_release_description":"— — — —"}]

let b = []

temp1.forEach((a,index_a) => { 
Object.values(a).every((value,index,array) => {
    let expression = new RegExp("processado", "i") //expression to search
    if (typeof value == "object") {
      return Object.values(value).every(valueOfObject => {    
        if (expression.test(valueOfObject)) {
          b.push(temp1[index_a])
          return false;
        } else {
          return true
        }
      })
    }
      else if (expression.test(value)){ 
      b.push(temp1[index_a])
      return false
      }
      else {
      return true
      }
  })
})
console.log(b)

更简单、更清晰的方法是使用递归和 filter() 和 some()。 every() 对我来说没有任何意义

let temp1 = [{"id":7089,"value":"R$ 50,00","name":"Daiany Nascimento","date":"18/03/2019","type":"Cobrança","status":{"status":"Paga","icon":"paid"},"credit_release_date":"Não Processado","credit_release_description":"— — — —"}]

function check(obj,regex){
  return Object.values(obj).some(x =>{
      let y;
      if(typeof x === "object") y = check(x,regex);
      return y || regex.test(x);
   });
}

let b = temp1.filter(x => check(x,/Processado/i))
console.log(b)
