javascript - 使用新键合并特定对象数组

Question

我正在尝试将两个对象合并为一个(obj1 和 obj2 合并为 objResult):

var obj1 = {
 0: [{obj1key1: 'obj1value1'}, {obj1key2: 'obj1value2'}],
 1: [{obj1key3: 'obj1value3'}, {obj1key4: 'obj1value4'}],
 2: [{obj1key5: 'obj1value5'}, {obj1key6: 'obj2value6'}]
};
var obj2 = {
 0: [{obj2key1: 'obj2value1'}, {obj2key2: 'obj2value2'}],
 1: [{obj2key3: 'obj2value3'}, {obj2key4: 'obj2value4'}],
 2: [{obj2key5: 'obj2value5'}, {obj2key6: 'obj2value6'}]};
var objResult = {
 0: {
   0: [{obj1key1: 'obj1value1'}, {obj1key2: 'obj1value2'}],
   1: [{obj2key1: 'obj2value1'}, {obj2key1: 'obj2value1'}]
 },
 1: {
   0: [{obj1key3: 'obj1value3'}, {obj1key4: 'obj1value4'}],
   1: [{obj2key3: 'obj2value3'}, {obj2key4: 'obj2value4'}]
 },
 2: {
   0: [{obj1key5: 'obj1value5'}, {obj1key6: 'obj1value6'}],
   1: [{obj2key5: 'obj2value5'}, {obj2key6: 'obj2value6'}]
 }
}

我尝试了 jQuery 和 lodash 的合并功能，但没有成功。 您能建议将这两个对象合并为一个的最佳方法吗？使用纯 JS 或 jquery/lodash。

Answer 1

迭代其中一个对象中的键，对于每个对象，将结果对象上的该键设置为包含两个原始对象中的值的对象。

function merge(obj1, obj2) {
    var objResult = {};

    Object.keys(obj1).forEach(function(key) {
        objResult[key] = {
            0: obj1[key],
            1: obj2[key]
        }
    })

    return objResult;
}

这假设两个对象具有相同的键集。如果不存在，您可以迭代两个对象的键，当该对象不包含该键时，这会将 undefined 设置为值。
