Question

I’m using Grails 1.3.6. I read the following JSON into a variable …

{
    "abc": { 
        "attr1": "value1",
        "attr2": "value2"
    },
    "def": { 
        "attr1": "value1",
        "attr2": "value2"
    },
    "ghi": { 
        "attr1": "value1",
        "attr2": "value2"
    },
    ...
}

If, in my controller, I’m passed a parameter referring to one part of the JSON object …

def section = params.section;   // could be "abc", "def", 'ghi", ...e

How do I access that part of the JSON assuming the above gets stored into a Groovy variable named “myJSONObject”? Thanks, – Dave

Answer 1

If you used JSON.parse() to create your myJSONObject, you can just do:

def value = myJsonObject[section]
