Get multiple JSON values from search in JS
问题
console.log(event.pos[0]['$'].a, event.pos[0]['$'].x, event.pos[0]['$'].z);
英文:
I need to loop thru json data looking for a keyword. Once found I need to pull 3 values to my console.log
This is for a Node.js project. The json is a local file.
How the data is laid out.
{"eventposdef": {"event": [{"$": {"name": "FIND THIS"},"pos": [{"$": {"a": "THIS VALUE 1","x": "THIS VALUE 2","z": "THIS VALUE 3"}},]}
Ive tried the following but it only returns the name.
// result is the entire file loaded. The below code does get part of the inquiryvar json = result;json.eventposdef.event.forEach(event => {if (event["$"].name === var2){console.log(event.name) //returns the nameconsole.log(event.pos) // returns nothingconsole.log(event.pos.a) //returns nothing}})
I expect to return...
"a" THIS VALUE 1"x" THIS VALUE 2"z" THIS VALUE 3

我不确定您是要按事件名称筛选还是打印所有位置，但您可以使用Object.keys(pos.$)来获取对象的所有属性并将它们打印到控制台上。这是我的参考代码，我跳过了null和undefined的检查条件。
const data = {"eventposdef": {"event": [{"$": {"name": "FIND THIS"},"pos": [{"$": {"a": "THIS VALUE 1","x": "THIS VALUE 2","z": "THIS VALUE 3"}},]}]}};// 遍历事件data.eventposdef.event.forEach(event => {// 检查事件名称是否是我们想要的if (event.$.name !== 'FIND THIS') {return;}event.pos.forEach(pos => {Object.keys(pos.$).forEach(key => {console.log(`"${key}" ${pos.$[key]}`);});});});
这段代码会遍历事件，检查事件名称是否为“FIND THIS”，然后遍历位置属性并将它们打印到控制台上。

I'm not sure if you want to filter by event name or print all pos, but you can use Object.keys(pos.$) to get all the properties of an object and print them to the console. This is my reference code, I skipped null and undefined check conditions.
