我有一个对象 A 和 B 。对象 B 将与 A 进行比较。 B 中的新内容应添加到 A 中。如果 A 和 B 处的键相同,则 B 的内容将替换为 A 。
简而言之: A 是我的默认对象,对象 B 应该覆盖内容或再次将其添加到对象 A 。
正确的方法是搜索重复的条目并将其删除。然后将对象B完全添加到A中。这是正确的吗?我该怎么办?
对象A如下:
{
"slidesPerView": 3,
"direction": "vertical",
"roundLengths": true,
"keyboard": {
"enabled": true,
"onlyInViewport": true
},
"breakpoints": {
576: {
"direction": "horizontal",
"slidesPerView": "auto"
}
}
}
对象B如下:
{
"slidesPerView": "auto",
"direction": "horizontal",
"roundLengths": false,
"breakpoints": {
576: {
"direction": "vertical",
"slidesPerView": 5
}
}
}
结果将是以下内容:
{
"slidesPerView": "auto",
"direction": "horizontal",
"roundLengths": false,
"keyboard": {
"enabled": true,
"onlyInViewport": true
},
"breakpoints": {
576: {
"direction": "vertical",
"slidesPerView": 5
}
}
}

实际上,您不需要搜索重复的密钥。您可以直接遍历objectB
,并将其每个密钥添加到objectA
for (var key in objectB) {
objectA[key] = objectB[key]; // If key exists in objectA, it will be overwritten with the value from objectB. If it doesn't, it will be created (with the value from objectB)
}
console.log(JSON.stringify(objectA)); // This should output the result you were looking for
