How to push data into a JSON variable
提问by Pacuraru Daniel
I have a JSON variable which looks like this :
我有一个 JSON 变量，如下所示：
{"events": [
{"event_id": "1", "event_name": "Breakfast"},
{"event_id": "1", "event_name": "Calling Bob"}
]}
I need to push another attribute in each event with javascript and make it look like this:
我需要使用 javascript 在每个事件中推送另一个属性，并使其看起来像这样：
{"events": [
{"event_id": "1", "event_name": "Breakfast", "event_type": "calendar"},
{"event_id": "1", "event_name": "Calling Bob", "event_type": "calendar"}
]}
回答by Alexander Pavlov
If you have
如果你有
var obj = {"events": [....
then just use
然后只需使用
for (var i = 0; i < obj.events.length; ++i)
obj.events[i].event_type = "calendar";
Or to optimise:
或者优化：
for (var i = 0, len = obj.events.length; i < len; ++i)
obj.events[i].event_type = "calendar";

Convert it to an Objectfirst:
将其转换为Object第一个：
var obj = JSON.parse(theJSON);
for(var i = 0; i < obj.events.length; ++ i)
obj.events[i].event_type = "calendar";
theJSON = JSON.stringify(obj);

var yourJson = {"events": [
{"event_id": "1", "event_name": "Breakfast"},
{"event_id": "1", "event_name": "Calling Bob"}
]};
for(var eventKey in yourJson.events) {
yourJson.events[eventKey]['event_type'] = 'calendar';
}
