]问题是我无法遍历 JSON 并推送 json1 中不匹配的键.我想比较 json1 和 json2，而 json1 中缺少的那些键应该使用 json2 中的键进行更新，我还想在从 json2 复制到 json1 时更新密钥candisplay。 请帮忙 我是JavaScript的新手，我没有编程知识
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
}
是我尝试遍历上述给定 JSON 并添加缺失值的代码
