Accessing JSON object properties directly and log it
提问by Anna
I'm trying to access JSON Object properties directly and log it, here is my function :
我正在尝试直接访问 JSON 对象属性并记录它，这是我的函数：
loadProcesses(filter?){
this._postService.getAllProcess(filter)
.subscribe(
res=> {
this.processListe = res;
// console.log(this.processListe.)
}
,null,
() =>{
console.log("get processes liste" + filter)
});
So this.processListe contain a JSON Object, and my JSON format is like this:
所以 this.processListe 包含一个 JSON Object，我的 JSON 格式是这样的：
{"Person": {
"id": "A256",
"name": "GET",
"status": "active",
"description": "hardworking, openminded",
...
So it will contains exactly the same things, for example if i want to simply print the label on a console log how can i do it ??
所以它将包含完全相同的东西，例如，如果我想简单地在控制台日志上打印标签，我该怎么做？

Are you looking for something like this:
你在寻找这样的东西：
function parseObject(obj)
{
for(var key in obj)
{
console.log("key: " + key + ", value: " + obj[key])
if(obj[key] instanceof Object)
{
parseObject(obj[key]);
}
}
}just call parseObject(res) in the subscribe method.
只需在 subscribe 方法中调用 parseObject(res) 即可。

parse it and access the fields.
解析它并访问字段。
var obj = JSON.parse(filter);
obj.Person.id;
//etc
回答by Jarod Moser
parse it in the .subscribe:
在 .subscribe 中解析它：
res => this.processListe = res.json();
回答by Brahim LAMJAGUAR
a better solution is to declare your response with any :
更好的解决方案是使用 any 声明您的响应：
loadProcesses(filter?){
this._postService.getAllProcess(filter)
.subscribe(
(res: any)=> {
this.processListe = res;
// console.log(this.processListe.)
}
,null,
() =>{
console.log("get processes liste" + filter)
});
this way you can access any attirbute in your response
这样你就可以在你的回复中访问任何属性
