如何比较两个多维数组并合并为一个数组
如何比较两个多维数组并合并为一个数组
提问于 2020-01-02 22:17:27
我正在寻找一种方法来比较和组合两个基于课程值的多维对象数组。我可以使用顶层的过滤方法让它工作，但不确定如何确保所有具有技能的级别都被深度合并。下面是一个示例：
var array1 = [
{

var array2 = [

const sameData = array1.map(
obj =>
array2.map(obj2 => {
if (obj.course === obj2.course) {
return {
...obj,
levelwithskills: obj.levelwithskills.map(
xlvl =>
obj2.levelwithskills.map(ylvl => {
if (xlvl.name === ylvl.name) {
return {

xskill =>
ylvl.skills.map(yskill => {
if (xskill.name === yskill.name) {
return {
...xskill,

}
return xskill;
})[0]
)
};
}
return xlvl;
})[0]
)
};
}
})[0]

console.log(sameData);
我正在寻找这样的东西，并将其合并为：

深度合并对象/数组：
摘自drupal - drupal_array_merge_deep_array并用JS重写)
function array_merge_deep_array(arrays) {
let result = [];
for (let i in arrays){
for (let key in arrays[i]){
const value = arrays[i][key];
// Renumber integer keys
if (typeof(key) === 'number') {
result.push(value);
}
else if (result[key] && typeof(result[key]) === 'object' && typeof(value) === 'object') {
result[key] = array_merge_deep_array([
result[key],
value,
]);
}
else {
result[key] = value;
}
}
}
return result;
