Question

在下面的javascript对象中，我想检查数组中的每个问题id是否在数组1中找到

arrayOne=[{"question":"100","response":"aaaa"},
             {"question":"200","response":"aaaa"}]  

arrayTwo=[{"question":"100","output":true},
             {"question":"200","output":true}]

示例

如果是arrayTwo

 arrayTwo=[{"question":"100","output":true}]

返回false

如果是arrayTwo

    arrayTwo=[{"question":"100","output":true},
             {"question":"200","output":true}]  

return true.

如何使函数检查两个数组？

Answer 1

您可以使用every()和find()执行此操作，结果会返回true/false。

var arrayOne = [{
  "question": "100",
  "response": "aaaa"
}, {
  "question": "200",
  "response": "aaaa"
}]

var arrayTwo = [{
  "question": "100",
  "output": true
}, {
  "question": "200",
  "output": true
}]

var result = arrayTwo.every(function(e) {
  return arrayOne.find(function(a) {
    return a.question == e.question;
  })
})

console.log(result)
