Obtain the information from a JSONP-formatted dataset

Just when I think I have mastered identifying an element in an object, I come across a situation where I am unable to obtain the desired value.

This part is successful and the data returned is accurate: A map click triggers the function MapClick(queryResults) which returns the following JSON object (this has been truncated for readability but it is properly formatted):

dojo.io.script.jsonp_dojoIoScript19._jsonpCallback({
"results": [
    {
        "layerId": 5,
        "layerName": "Building",
        "value": "Name of item clicked",
        "displayFieldName": "name",
        "attributes": {
            "ID": "123",
            "name": "Name of item clicked",
            "Variable1": "Some bit of information",
            "Variable2": "Some other bit of information",
            ...
            ...

All I am attempting to do is retrieve either the results[0].value OR results[0].attributes.name, which should return "Name of item clicked" in this example. The layerId, layerName, value, and displayFieldName are commonly accessed data that are returned, but the same information can also be found within the attributes.

I have attempted

console.log(results[1].attributes.name);
and console.log(results) without success.

Answer №1

It turns out that in order to properly handle the MapClicked function, the name queryResults was necessary. Therefore, the correct syntax would be: queryResults[0].value. When you encounter open brackets [, it indicates the need for some numerical value within them ] (e.g. queryResults[0].value or

queryResults[99].someothervariable
). At least, I believe this is an accurate representation.
