要求找出包含关键字key的项并生成新数组，如何处理？

Question

        var key = "760";
        var obj ={"code":1,"msg":"success","list":
        [
          {"cc":"1<text style=\"color:red\">3322<\/text>057549","number":"13322057549"},
          {"cc":"1<text style=\"color:red\">3337<\/text>606240","number":"13337606240"},
          {"cc":"1<text style=\"color:red\">3337<\/text>684403","number":"13337684403"},
          {"cc":"1<text style=\"color:red\">3337<\/text>560941","number":"13337560941"},
          {"cc":"1<text style=\"color:red\">3337<\/text>658540","number":"13337658540"},
          {"cc":"1<text style=\"color:red\">3337<\/text>553743","number":"13337553743"},
          {"cc":"1<text style=\"color:red\">3337<\/text>602824","number":"13337602824"},
          {"cc":"1<text style=\"color:red\">3337<\/text>608045","number":"13337608045"},
          {"cc":"1<text style=\"color:red\">3337<\/text>698326","number":"13337689326"},
          {"cc":"1<text style=\"color:red\">3337<\/text>601734","number":"13337601734"}
        ]
      };

参考GPT和自己的思路：

可以使用 JavaScript 中的 filter() 方法来筛选包含关键字 key 的项，并且生成新的数组。具体的实现方法如下：

var key = "760";
var obj = {"code":1,"msg":"success","list":
[
    {"cc":"1<text style=\"color:red\">3322<\/text>057549","number":"13322057549"},
    {"cc":"1<text style=\"color:red\">3337<\/text>606240","number":"13337606240"},
    {"cc":"1<text style=\"color:red\">3337<\/text>684403","number":"13337684403"},
    {"cc":"1<text style=\"color:red\">3337<\/text>560941","number":"13337560941"},
    {"cc":"1<text style=\"color:red\">3337<\/text>658540","number":"13337658540"},
    {"cc":"1<text style=\"color:red\">3337<\/text>553743","number":"13337553743"},
    {"cc":"1<text style=\"color:red\">3337<\/text>602824","number":"13337602824"},
    {"cc":"1<text style=\"color:red\">3337<\/text>608045","number":"13337608045"},
    {"cc":"1<text style=\"color:red\">3337<\/text>698326","number":"13337689326"},
    {"cc":"1<text style=\"color:red\">3337<\/text>601734","number":"13337601734"}
]
};

var newList = obj.list.filter(function(item){
    return item.cc.includes(key);
});

console.log(newList);

在上面的代码中，我们先定义了关键字 key 和包含数据的对象 obj，然后使用 filter 方法来筛选包含 key 的项，并且生成新的数组 newList。在 filter 方法中，我们使用 includes 方法来判断一个字符串是否包含另一个字符串。最后，我们使用 console.log 方法来输出 newList 数组。
