Sometimes the key name in the JSON object changes

But every time there is a pattern of change.

Contains a specific string prefix

So if you want to get its value, but

By traversing key-value pairs

If it is determined that the key name contains a specific string, the value of the key is taken out.

The source code is as follows

Import console

Var str = / / {"value": {"element-6066-11e4-a52e-4f735466cecf": "cb830670-0e36-4593-96c8-e119febcb0a1"}}

Import web.json

Var tab = web.json.parse (str)

Var the value you want to take = ""

For (KJO v in tab.value) {

/ / console.log (kpene v)

If (string.find (k, "element")) {

/ / console.log (v)

The value you want to take is v

}

}

Console.log (the value you want)

Console.pause (true)
