有一个对象数组（489个对象）。对象具有一个具有另一个对象（子对象）的键。子对象的数量是不确定的。
我也创建了a fiddle。请在下面找到搜索功能：
function getObjects(obj, key, val) {
var objects = [];
for (var i in obj) {
if (!obj.hasOwnProperty(i)) continue;
if (typeof obj[i] == 'object') {
parent = obj;
objects = objects.concat(getObjects(obj[i], key, val));
} else {
if(obj[i].toString().toLowerCase().indexOf(val.toString().toLowerCase()) > -1) {
objects.push(obj);
}
}
}
return objects;
}
这里我想在包含嵌套对象（asset_info）的对象数组中搜索搜索字符串。没有getObjects的搜索可以正常使用以下功能。
this.data.filter(function(row){
var flag;
for(var prop in (columns.length > 0 ? columns : row)){
flag = false;
flag = row[columns.length > 0 ? columns[prop] :
prop].toString().toLowerCase().indexOf(searchString.toString().toLowerCase()) > -1;
if(flag)
break;
}
return flag;
在上面的函数中，我无法在嵌套对象（asset_info）中搜索。所以我一直在使用我在网上找到的getObject函数。
现在问题是我无法搜索包括asset_info但无法返回其父级。例如，如果我搜索emc，搜索应该从data返回第二个对象。
更新 still not able to return parent of a child where search string has been found

如果我搜索字符串＆＃39; emc＆＃39;，它应该返回2个对象。第一个对象只有一个孩子，因为只有一个对象有＆＃39;制造商＆＃39;作为＆＃39; emc＆＃39;。
输出应为：

如果在子对象中找到搜索字符串，如何在包括嵌套对象和返回父对象的对象数组中搜索字符串？
答案 0 :(得分：3)
You could use an iterative and recursive approach and return the result of the check and build new objects and arrays if the children matches the search value.
function getValue(item) {
if (Array.isArray(item)) {
return item.reduce(iterA, undefined);
}
if (item && typeof item === 'object') {
return iterO(item);
}
if (typeof item !== 'object' && item.toString().toLowerCase().indexOf(search) !== -1) {
return item;
}
}
function iterO(o) {
var temp = Object.keys(o).reduce(function (r, k) {
var value = getValue(o[k]);
if (value) {
r = r || {};
r[k] = value;
}
return r;
}, undefined);
if (temp) {
Object.keys(o).forEach(function (k) {
if (!(k in temp)) {
temp[k] = o[k];
}
});
}
return temp;
}
function iterA(r, a) {
var value = getValue(a);
if (value) {
r = r || [];
r.push(value);
}
return r;
}
