jca*_*web 11 php jquery nested codeigniter-2
编辑:经过很好的回答@ vadim-ashikhman.问题的结尾.
我正在使用的资源:
我设法添加类别和子类别没有任何问题.
我还能够使用可嵌套的jQuery库显示所有类别的菜单.
到现在为止还挺好.
现在,当我尝试通过拖放进行排序时.捕获整个数组,这是一个例子:
[{
"id": 1,
"children": [{
"id": 2,
"children": [{
"id": 3
}, {
"id": 6
}, {
"id": 5
}, {
"id": 7
}, {
"id": 9
}]
}, {
"id": 8,
"children": [{
"id": 10,
"children": [{
"id": 11
}, {
"id": 12
}, {
"id": 13
}, {
"id": 14
}, {
"id": 15
}]
}, {
"id": 16,
"children": [{
"id": 17
}, {
"id": 18
}, {
"id": 19
}, {
"id": 20
}]
}]
}, {
"id": 22,
"children": [{
"id": 23
}, {
"id": 24
}, {
"id": 25
}, {
"id": 26
}]
}, {
"id": 27,
"children": [{
"id": 28
}, {
"id": 29
}, {
"id": 30
}, {
"id": 31
}]
}, {
"id": 32
}, {
"id": 39
}, {
"id": 40
}]
}]

但不是如何更新位置,这让我感到困惑,我花了近16个小时运行测试,但没有任何结果.
没有任何有利的结果.
所以我来找你,看看你是否可以帮助我.

TADA!而且效果很好
当您将节点移动到新位置时,获取新位置的前一个节点和父节点:
setNodeAsNextSibling()
库中的方法。您不需要捕获和更新整个树。
