What should json look like

A JSON string can be stored in its own file, which is basically just a text file with an extension of. You can include the same basic data types inside JSON as you can in a standard JavaScript object — strings, numbers, arrays, booleans, and other object literals. This allows you to construct a data hierarchy, like so:. For example:. To access data further down the hierarchy, you have to chain the required property names and array indexes together.

For example, to access the third superpower of the second hero listed in the members list, you'd do this:. Try loading this up and then accessing data inside the variable via your browser's JavaScript console.

Below is also valid JSON, for example:. The above is perfectly valid JSON. You'd just have to access array items in its parsed version by starting with an array index, for example [0]["powers"][0]. So, let's work through an example to show how we could make use of some JSON formatted data on a website. To begin with, make local copies of our heroes. We are going to load it into our page, and use some nifty DOM manipulation to display it, like this:. This is a very useful JavaScript object that allows us to make network requests to retrieve resources from a server via JavaScript e.

Search for: Search. It is a collection of key-value pairs and always separated by a comma and enclosed in curly brackets. For instance, if I needed to include information about myself and my brother in one variable, I might use the following:. To access this information, we need to access the array index of the person we wish to access. For example, we would use the following snippet to access info stored in family :.

NOTE: This is beneficial if it will be necessary to loop through stored information, as it lends itself to a for loop with an automatically incrementing value. Another way to store multiple people in our variable would be to nest objects. To do this, we would create something similar to the following:. Accessing information in nested objects is a little easier to understand; to access information in the object, we would use the following snippet:. You can receive pure text from a server and use it as a JavaScript object.

You can send a JavaScript object to a server in pure text format. You can work with data as JavaScript objects, with no complicated parsing and translations. Report Error.
