Selecting child elements #14

Closed tbett closed 8 years ago

tbett commented 8 years ago

Great project. What is the method for selecting a child element? For example - dimensions > length. JSON("dimensions")("length")?

Also, select by index value for json object array - JSON(0)("dimensions")("length")?

[ { "id": 2, "name": "An ice sculpture", "price": 12.50, "tags": ["cold", "ice"], "dimensions": { "length": 7.0, "width": 12.0, "height": 9.5 } } ]

Thank you.

You are almost there.

All you need to do is to assign the returning value of the parse() method to an object and it will give you a reference to a JSONarray object.

set jsonArr = JSON.parse(yourJSONarrayString)

response.write jsonArr(0)("dimensions")("length") ' direct and easy access, valid for single operations

If you have to access many fields, a better (faster) way should be:

set obj = jsonArr(0)
set dimensions = obj("dimensions")

response.write dimensions("length")

Thank you! This is exactly the package that is needed to extend ASP Classic a couple more years!!! Again, thank you for taking the time to put this together and answering my questions so quickly.
