在Javascript中通过递归迭代映射嵌套JSON
想象一下,这个JSON包含注释并通过AJAX接收:在Javascript中通过递归迭代映射嵌套JSON,javascript,json,coffeescript,iterator,nested,Javascript,Json,Coffeescript,Iterator,Nested,想象一下,这个JSON包含注释并通过AJAX接收: json = 'comments': [ {'id':1,'parent':0}, {'id':2,'parent':1}, {'id':3,'parent':2}, {'id':4,'parent':0}] 要渲染它们,我需要如下映射它们: target_object= comments: [ {id:1,parent:0, children:[ {id:2,parent:1, childre
json = 'comments': [
{'id':1,'parent':0},
{'id':2,'parent':1},
{'id':3,'parent':2},
{'id':4,'parent':0}]
要渲染它们,我需要如下映射它们:
target_object= comments: [
{id:1,parent:0, children:[
{id:2,parent:1, children: [
{id:3,parent:2}]}]},
{id:4,parent:0, children:[]}]
问题:
我花了一些时间终于解决了这个问题:
target = []
recurs = (id,json,form, single = []) ->
for com in json.comments
if com.parent is id
single.push com
if !single[single.length - 1].children?
single[single.length - 1].children = []
shingle = single[single.length - 1].children
recurs(com.id,json,form, shingle)
target[0] = single if !target[1]?
return
recurs(0, json, target)
如果有人能重新考虑代码或给出建议,将很高兴听到!
编辑
也许有人会发现它很有用,下面是通过上述方法格式化注释的脚本:
target = $('.comments')
recurs = (id,json,form) ->
for com in json.comments
if com.parent is id
form.append($("<div class='well'>#{com.id}</div>"))
if !form.children('.well:last-child').children('.children:last-child').length
form.children('.well:last-child').append('<div class="children"></div>')
shingle = form.children('.well:last-child').children('.children')
recurs(com.id,json,shingle)
return
recurs(0, json, target)
target=$('.comments')
递归=(id,json,form)->
用于json.comments中的com
如果com.parent是id
append($(“#{com.id}”))
如果form.children('.well:last child')。children('.children:last child')。长度
form.children('.well:last child')。append('')
shingle=form.children('.well:last children')。children('.children'))
递归(com.id、json、shingle)
回来
递归(0,json,目标)
