javascript - Dynamically create nested json objects

Question

I want to be able to create and object like this

{'someKey':
 [{'someSubKey1': 'value1'},
 {'someSubKey2': 'value2'},
 {'someSubKey3': 'value3'}]
}

I tried a lot but I think I'm missing something

first of all I created an array and pushed the elements, then I did a JSON parse and finally a join (","), but the result wasn't the expected.

Some help?

• emed: The format is a little different: {'someKey': {'someSubKey1': 'value1', 'someSubKey2': 'value2', 'someSubKey3': 'value3'} }
• Felix Kling: That is not a valid object. Do you want to create an array of objects each with a single property? Or should someSubKey1, someSubKey2, etc all be part of the same object? I recommend to read a tutorial about data structure in JS: eloquentjavascript.net/04_data.html . Also, what has JSON to do with it?
• Mojtaba: I tried a lot. Could you please put the codes you tried?

Answer 1

You need to put the contents in an array with []. Wrap you inner json inside an array like

var obj = {'someKey': [
 {'someSubKey1': 'value1'},
 {'someSubKey2': 'value2'},
 {'someSubKey3': 'value3'}]
}
console.log(obj);

If you need to access your data structure like myvar.someKey.someSubKey1, consider this structure:

{ 'someKey': 
 {
 'someSubKey1': 'value1',
 'someSubKey2': 'value2',
 'someSubKey3': 'value3'
 }
}

If you'd like to go with myvar.someKey[0].someSubKey1, try this:

{'someKey': 
 [
 {'someSubKey1': 'value1'},
 {'someSubKey2': 'value2'},
 {'someSubKey3': 'value3'}
 ]
}
