js递归如何生成该数据的预览json格式?-灵析社区
古典研发君需求就是通过json生成json，简化后的格式如下，如何通过递归的方式生成这些数据表示的最终格式？求教 //这个是各个类型生成的默认值 const defaultVal = { string:"默认值", int:1, float:0.1, double:10.34, boolean:false, array:null } //这个是json待转化的 [ { "type": "object", "propertyName": "user", "children": [ { "type": "string", "propertyName": "name", "children": null }, { "type": "int", "propertyName": "age", "children": null, }, { "type": "array", "propertyName": "data", "children": [ { "type": "object", "name": "name", "children": null } ] } ] } ] //上述转化结果为： { name:'默认值', age:1, data:[{}] }
生成头像function toData(rule, defVal, init) {
const copy = val => JSON.parse(JSON.stringify(val));
const initial = init ?? copy(defVal[rule.type]);
return rule.children ? rule.children.reduce((res, v) => {
if(Array.isArray(res)) res.push(toData(v, defVal));
else if({}.toString.call(res) == '[object Object]') toData(v, defVal, res[v.propertyName] = copy(defVal[v.type]))
return res;
}, initial) : initial;
}
toData(
{
"type": "object",
"propertyName": "user",
"children": [
{
"type": "string",
"propertyName": "name",
"children": null
},
{
"type": "int",
"propertyName": "age",
"children": null,
},
{
"type": "array",
"propertyName": "data",
"children": [
{
"type": "object",
"name": "name",
"children": null
}
]
}
]
},
{
string:"默认值",
int:1,
float:0.1,
double:10.34,
boolean:false,
array:[],
