我需要遍历所有级别并按"id"匹配并获取"内容"的值。
var id = "0-1-0-0-0";
如果 JSON id与 id 匹配，则返回 content 的值。应该返回10667,10668
提前感谢！
基本上，您可以遍历对象中的所有元素，如果找到所需的id，则停止迭代。
这个问题的问题是第一级的半级，id像1(0级(，1-(1级(和1-0(2级(以及下一个级别都用破折号隔开。
此建议使用 String#indexOf 并检查路径，所需索引为 0，并迭代该检查是否为真。如果找到完整路径，则返回对象。如果未找到，则继续迭代和递归。
function getObject(object, path) {
function getPart(o) {
if (!path.indexOf(o.id)) {
if (path === o.id) {
result = o;
return true;
}
return Array.isArray(o.item) && o.item.some(getPart);
}
return false;
}
var parts = path.split('-'),
result;
getPart(object);
return result;
}
