If this is a Numberit indicates the number of space characters to use as white space; this number is capped at 10 if it is greater, the value is just Values less than 1 indicate that no space should be used.

If this is a Stringthe string or the first 10 characters of the string, if it's longer than that is used as white space. If this parameter is not provided or is nullno white space is used. As a functionit takes two parameters: the key and the value being stringified. The object in which the key was found is provided as the replacer's this parameter. Initially, the replacer function is called with an empty string as key representing the object being stringified.

It is then called for each property on the object or array being stringified. Note: You cannot use the replacer function to remove values from an array. If you return undefined or a function then null is used instead.

Note: If you wish the replacer to distinguish an initial object from a key with an empty string property since both would give the empty string as key and potentially an object as valueyou will have to keep track of the iteration count if it is beyond the first iteration, it is a genuine empty string key.

Note that since the JSON format doesn't support object references although an IETF draft existsa TypeError will be thrown if one attempts to encode an object with circular references. To serialize circular references you can use a library that supports them e. Therefore, if compatibility with older JavaScript engines is required, it is perilous to directly substitute the string returned by JSON.

Note : Properties of non-array objects are not guaranteed to be stringified in any particular order. Do not rely on ordering of properties within the same object within the stringification. In a case where you want to store an object created by your user and allowing it to be restored even after the browser has been closed, the following example is a model for the applicability of JSON.

Engines implementing the well-formed JSON. Before this change JSON. But with this change JSON. This change should be backwards-compatible as long as you pass the result of JSON.

Sign in to enjoy the benefits of an MDN account.You got back a JSON string either as a response from a REST service, passed through from your visual force page via remote action or passed from your lighting component to your apex controller, now how do you parse this information?

It is good to get back to the basics and understand a little bit how the JSON string is structured and how the parsing is done. What is JSON? It is based on a subset of JavaScript language the way objects are built in JavaScript. Deserialized into standard object sample — only the name attribute can be mapped to the Account object, the rest are ignored.

Line: 19, Column: 1 System. This is useful for retrieving specific data eg. Here is a slight variation of our example, an array of objects and one of the attributes is not a supported variable naming convention in Apex. Or use the JSON. Kudos to the people behind this tool for making it available to us devs.

So what I did was using while statements I looped through the array of objects and traversed each token and mapped the attributes to the Apex Class. Sample codes used in the tutorial can be found in my Github repo here. Your email address will not be published.

I've found a method called JSON. Edit: I have a year more experience as a developer now and I realize my answer here was a bit too simplistic.

If you are looking to deserialize untyped without custom classes so basically assume the data has the right structure at runtime you can do it but it requires some steps. My original answer looked like this:. It's a bit tiresome but it can be done. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

Parsing JSON and stringify

Is JSON. In other words, is JSON. Or is necessary but not sufficient? Or is it neither necessary nor sufficient for serialization of JavaScript objects?

Serialization is the act of converting data into a format that can be written to disk or transmitted over the network or written on paper if that's what you want. JSON is one form of text-based serialization format and is currently very popular due to it's simplicity. It's not the only one though. Previously you had to use libraries or write a recursive descent parser to do the job. So, is JSON.

Yes, if the output format you want is JSON. There are limitations to the JSON format. JSON also can't encode circular references.

Most other serialization formats have this limitation as well but since JSON looks like javascript syntax some people assume it can do what javascript object literals can.

It can't. Of course, you can serialise any way you want, including any number of custom methods, but JSON has become an increasingly popular method.

The most obvious benefit of JSON is that it represents objects in the same way that JavaScript object literals do, though it is slightly less flexible. For one reason or another, JSON has more-or-less supplanted XML as the preferred serialisation for sending data between the server and browser. I myself have found it convenient to use JSON functions to store a more complex data structure in a single field of a database without JavaScript anywhere in sight.

The short answer is yes, for the most part it is a sufficient step to serializing most data non-binary.

It is not, however, necessary as there are alternatives. Learn more. Asked 4 years, 11 months ago. Active 7 months ago. Viewed 7k times. Alexander Mills. Alexander Mills Alexander Mills 1.
