我在 JSON 中有两个数组，例如：
proj1 proj1
taska taska
charge1 charge1
charge2 taskb
taskb charge1
charge1 charge2
proj2 proj2
taska taska
taskb charge1
charge1 taskb
charge1
taskc
proj3
taska
我希望他们合并成类似的东西：
proj1
taska
charge1
charge2
taskb
charge1
charge2
proj2
taska
charge1
taskb
charge1
taskc
proj3
taska
我尝试使用 jQuery 的extend方法递归合并，但这失败了，因为我需要合并数组，extend而是替换数组。我需要遍历每个列表的每个级别，还是有更优雅的解决方案，比如extend合并对象和数组？
编辑这里是我的列表之一的 JSON 示例：
{
"projects": [
{
"projectName": "JobIdTooManyChar",
"tasks": [
{
"name": "Process Graphics",
"charges": [
{
"date": "2012-06-18",
"hours": 1
},
{
"date": "2012-06-28",
"hours": "5"
}
]
},
{
"name": "Custom Software",
"charges": [
{
"date": "2012-06-18",
"hours": 1
},
{
"date": "2012-06-19",
"hours": 24
}
]
},
{
"name": "Consulting",
"charges": [
{
"date": "2012-06-18",
"hours": 1
},
{
"date": "2012-06-21",
"hours": 1
}
]
}
]
},
{
"projectName": "JobIdTooManyChar",
"tasks": [
{
"name": "CAD Drawings",
"charges": [

}
