问题是我无法遍历jsons并推送json1.i中不匹配的键想要比较json1和json2而json1中缺少的那些键应该用键更新当我从json2复制到json1时，我想更新密钥candisplay。请帮助我是javascript的新手，我对编程没有任何了解

答案 0 :(得分：0)

var L = json1.length;
var L1 = json2.length;
 for (var i = 0; i < L; i++) {
  var obj = json1[i];
   for (var j in obj) {
    for (var x = 0; x < L1; x++) {
        var obj1 = json2[x];
        for (var k in obj1) {
            if (i == x && j == k) {
                if (obj[j] == obj1[k]) {
                    continue;
                } 
                else 
                {
                    json1[i][j] = json2[x][k];
                }
            }
        }
    }
  }
}

for(i in json1){
 var obj2=json1[i]
 for( j in obj2)
 if(json1[i][j]===false)
json1[i][j]=true

}

是我试图迭代上面给出的json并且还添加缺失值的代码
