<p>我有两个对象的动态数组，如下所示（这是一个包含n个对象的动态数组）：</p> <pre class="brush:php;toolbar:false;">serverArray = [ {"id":"field1","mandatory":false,"visible":false}, {"id":"field2","mandatory":false,"visible":false}, {"id":"field3","mandatory":false,"visible":false}, {"id":"field4","mandatory":false,"visible":false} ] localArray = [ {"id":"field1"}, {"id":"field2","mandatory":false}, {"id":"field3","mandatory":true,"visible":false}, {"id":"field4","mandatory":false,"visible":true}, {"id":"field5","mandatory":false,"visible":true}, {"id":"field6","mandatory":true,"visible":false}, ]</pre> <p>我将这两个数组合并为具有相同ID的对象，如下所示：</p> <pre class="brush:php;toolbar:false;">for (let x = 0; x < serverArray.length; x++) { for (let y = 0; y < localArray.length; y++) { if (serverArray[x].id == localArray[y].id) { // serverArray[x].id/localArray[y].id = 'field1', 'field2' for (let key in localArray[y]) { //key = 'id', 'mandatory', etc serverArray[x][key] = localArray[y].hasOwnProperty(key) ? localArray[y][key] : serverArray[x][key]; //Override with local field attribute value (if present) in final returned response } } } }</pre> <p>然而，我还希望在最终的<code>serverArray</code>中包含那些不在<code>serverArray</code>中的ID（即上面示例中的<code>field5</code>，<code>field6</code>），并且这些字段也会失败上述条件（即<code>serverArray[x].id == localArray[y].id</code>），我希望这些字段也作为最终<code>serverArray</code>的一部分，即在我的最终<code>serverArray</code>中还应包含以下两个对象：</p> <pre class="brush:php;toolbar:false;">{"id":"field5","mandatory":false,"visible":true}, {"id":"field6","mandatory":true,"visible":false},</pre> <p>有没有办法实现这个要求？</p>

let mergedFields = {};

// 根据共同的ID进行初始合并
for (let y = 0; y < localArray.length; y++) {
    const localField = localArray[y];
    const serverField = serverArray.find(field => field.id === localField.id);

    if (serverField) {
        mergedFields[localField.id] = {
            ...serverField,
            ...localField
        };
    } else {
        mergedFields[localField.id] = localField;
    }
}

// 添加在mergedFields中不存在的剩余localArray字段
for (let y = 0; y < localArray.length; y++) {
    const localField = localArray[y];
    if (!mergedFields.hasOwnProperty(localField.id)) {
        mergedFields[localField.id] = localField;
    }
}

// 将mergedFields对象转换回数组
const mergedServerArray = Object.values(mergedFields);

console.log(mergedServerArray);
