I have a JSON file with order data. The JSON file is formatted like this:

{
  "orders": [
    {"name": "Peter", "email": "peter@aol.com"}

    {"name": "David", "email": "david@aol.com"}

    { "name": "George", "email": "george@aol.com"}
  ]
}

As you can see; all the data is part of a branch called "orders" and then each order is its own branch, but the branch doesn't have a name.

I am trying to generate a list of the "name"s in the dataset.

With a simplified dataset, I would do something like:

$(data).each(function(i, name){
    $('#namesText').append($("li")
        .append($("li").append(name.name))
  });
})

This however doesn't work as the data is not in the first level of the tree.

My question is, how do I go down levels when the levels don't have a name?


This sounds like a DFS problem where each object has keys that can possibly be a primitive data type or another object. Since the name field could be at any level in this given constraint you need to solve for, I would say use DFS algo where it traverses each key in the object and if there is another object, look into that until you find a name field. Better solution is to redesign the data structure so that you are guaranteed to know which level and location the name field is at any time.

Since the name field could be at any  The getJSON() method in jQuery fetches JSON-encoded data from the server using a GET HTTP request. Syntax: $(selector).getJSON(url,data,success(data,status,xhr)) Parameters: This method accepts three parameters as mentioned above and described below: url: It is required parameter. It is used to specify the URL in the form of a string to which


If you want a list of the name property from the elements of the orders array you could use Array.map:

const names = myJson.orders.map(o => o.name);

jQuery.getJSON(), jQuery.getJSON( url [, data ] [, success ] )Returns: jqXHR. Description: Load JSON-encoded data from the server using a GET HTTP request. The $.getJSON () method loads the JSON-encoded data from the server using a GET HTTP request based on a URL to which the request is sent. You may then choose to use $.parseJSON () method to parse the JavaScript object or array as defined by the JSON structure.


Try

namesText.innerHTML= data.orders.map(p=>`<li>${escape(p.name)}</li>`).join``

var data = {
  "orders": [
    {
      "name": "Peter",
      "email": "peter@aol.com",
    },
    {
      "name": "David",
      "email": "david@aol.com",
    },
    {
      "name": "George",
      "email": "george@aol.com",
    }
  ]
}

namesText.innerHTML= data.orders.map(p=>`<li>${escape(p.name)}</li>`).join``
<ul id="namesText"></ul>

Parsing a large JSON file efficiently and easily, When parsing a JSON file, or an XML file for that matter, you have two options. You can read the file entirely in an in-memory data structure (a tree  The jsonparser unit does contain a JSON parser, and must be included once in the project to be able to parse JSON. The jsonparser unit uses the SetJSONParserHandler call to set a callback that is used by GetJSON to parse the data. If UseUTF8 is set to true, then unicode characters will be encoded as UTF-8.


javascript get json data Code Example, var personObject = JSON.parse(jsonPerson); //parse json string into JS object. Shell/Bash queries related to “javascript get json data”. parseJSON · json in array​  The tree can then be navigated and queried. This programming model is the most flexible and enables processing that requires random access to the complete contents of the tree. However, it is often not as efficient as the streaming model and requires more memory. The streaming API provides a way to parse and generate JSON in a streaming fashion.
