求助高手指导,先谢为敬.
用简单的json来测试是可以的过滤的:
import console;
var tab = {}
tab.a = 1;
tab.b = {1;2;3}
tab.c = 3;
console.varDump(tab)
//tab.a = null;
for k,v in table.eachName(tab){
if(k="b"){
tab[k] = null;
}
}
console.varDump(tab)
console.pause(true);
然后用复杂点的json来测试,过滤不了,
我只需要保留
"name":"叶子节点232",
"open":false,
"nocheck":false,
等几个特定键名的

输出:
参数位置:1
数据类型:table
变量值: {
check_Child_State = null
check_Focus = null
checkedOld = null
children = null
chkDisabled = null
editNameFlag = null
getCheckStatus = null
getIndex = null
getNextNode = null
getParentNode = null
getPath = null
getPreNode = null
halfCheck = null
isAjaxing = null
isFirstNode = null
isHover = null
isLastNode = null
isParent = null
level = null
name = null
nocheck = null
open = null
parentTId = null
tId = null
zAsync = null
}
为什么会变成这样,不是应该把键名不等于"name"和"children"的键值对清除掉吗?为何全变成了值为null?
- Admin Time:2018-04-28 15:02:38感谢群友炸二串帮解决了
winform.button2.oncommand = function(id,event){
//这个可以成功过滤了
var tab = web.json.parse(jsonStr)
var fields = {name ="name"; open="open"; nocheck = "nocheck"}
fieldsFilter = function(data){
var arr = {}
for(k,v in data){
var field = fields[ k ]
if(field) arr[field] = v
if(type(v) === "table"){
arr.children = {}
for(kk,vv in v){
table.push(arr.children, fieldsFilter(vv))
}
}
}
return arr
}
console.dumpJson( fieldsFilter(tab) )
} - Admin Time:2018-04-28 16:17:55aardio官方新出的函数,可以很简洁地解决json过滤的问题:
winform.button3.oncommand = function(id,event){
//aardio的table库新函数
var tab = web.json.parse(jsonStr)
var fields = {name ="name"; open="open"; nocheck = "nocheck"}
tab = table.mapr(tab,lambda(v,k) fields[k] ? v );
winform.edit.print(tab)
