Last updated at Posted at 2022-05-02

コード


//varを使用すると再宣言、初期化によるバグを起こしやすくなるため、今は非推奨だから使わないほうが良い
let items = [];
const results = [
    {'name' : '田中',  'japanese' : 83, 'math' : 57, 'science' : 43,  'social' : 72, 'english' : 78},
    {'name' : '渡部',  'japanese' : 62, 'math' : 88, 'science' : 70,  'social' : 66, 'english' : 38},
    {'name' : '品川',  'japanese' : 23, 'math' : 33, 'science' : 53,  'social' : 17, 'english' : 07},
    {'name' : '滝谷',  'japanese' : 93, 'math' : 89, 'science' : 79,  'social' : 96, 'english' : 91},
    {'name' : '川原田','japanese' : 55, 'math' : 56, 'science' : 60,  'social' : 54, 'english' : 66},
    {'name' : '一色',  'japanese' : 27, 'math' : 47, 'science' : 100, 'social' : 42, 'english' : 38},
];

 results.forEach(function(result) {
    if(result.japanese > 80) items.push(result);
 })

// jqueryなら

$.each(results,function() {
      if(this.japanese > 80) items.push(this);
})
 
console.log(items);

結果

[
  {
    name: '田中',
    japanese: 83,
    math: 57,
    science: 43,
    social: 72,
    english: 78
  },
  {
    name: '滝谷',
    japanese: 93,
    math: 89,
    science: 79,
    social: 96,
    english: 91
  }
]
