Encountering a parsing error with JSON - Type mismatch detected

I have a sample JSON data that looks like this:

{
 "findItemsByKeywordsResponse":[
  {
     "ack":[
        "Success"
     ],
     "version":[
        "1.13.0"
     ],
     "timestamp":[
        "2015-02-10T18:12:21.785Z"
     ],
     "searchResult":[
        {
           "@count":"100",
           "item":[
              {
                 "itemId":[
                    "371250980931"
                 ],
                 "title":[ etc etc...

I am attempting to parse it in the following manner:

function _cb_findItemsByKeywords(root) {
  var items = root.findItemsByKeywordsResponse[0].searchResult[0].item || [];
  etc etc...
}

Unfortunately, I encounter the following error:

TypeError: root.findItemsByKeywordsResponse is undefined
    var items = root.findItemsByKeywordsResponse[0].searchResult[0].item || [];
    ----^

Any suggestions on what mistake I might be making?

Answer №1

To effectively utilize the information retrieved, it is essential to properly parse the root data. 

function _cb_findItemsByKeywords(root) {
  root = JSON.parse(root);
  var items = root.findItemsByKeywordsResponse[0].searchResult[0].item || [];
  // Additional logic implementation here...
}

Keep in mind that a JSON object is simply a string in Javascript and needs to be parsed into an Object to be used effectively.
