Introduction to jQuery ajax send JSON

So with the help of this request and method, we can easily load the external data directly into the current webpage. The JSON is a JavaScript library and it is used to traverse the HTML document. jQuery takes a lot of normal errands that require many lines of JavaScript code to achieve and wraps them into strategies that you can call with a solitary line of code.

jQuery likewise works on a ton of the convoluted things from JavaScript, similar to AJAX calls and DOM control. The jQuery library contains the accompanying components:.

HTML/DOM control. HTML occasion techniques.

  • Impacts and activities. jQuery improves on HTML report navigating, occasion dealing with, vivifying, and Ajax communications for fast web advancement.
  • jQuery is a JavaScript tool compartment intended to work on different errands by composing less code. Here is the rundown of significant center components upheld by jQuery −.
  • DOM control: JQuery simplified it to pick DOM parts, orchestrate them, and change their substance by using a cross-program open source selector engine called Sizzle.

Occasion taking care of JQuery offers an exquisite method to catch a wide assortment of occasions, for example, a client tapping on a connection, without the need to mess the HTML code itself with occasion overseers.

  • Most recent Technology: JQuery upholds CSS3 selectors and fundamental XPath grammar.

In this article, we’ll take a gander at stacking JSON information utilizing an HTTP GET demand (we can likewise utilize different action words, like POST). For what reason would we pick JSON over say XML? The vital benefit of utilizing JSON is productivity.

JSON is less verbose and jumbled, bringing about fewer bytes and a quicker parse measure. This permits us to handle a greater number of messages sent as JSON than as XML.

Besides, JSON has an exceptionally effective and regular item portrayal prompting configurations, for example, BSON, where JSON-like articles are put away in a twofold organization.

The syntax for JSON jQuery is as follows. The $.getJSON() technique is a convenient partner for working with JSON straightforwardly in the event that you don’t need a lot of additional design.

Basically, it comes down to the more broad $.ajax() assistant, with the ideal choices being utilized certainly.

  • Now let’s see how we can send JSON instead of a query as follows.
  • There are different ways to use JSON instead of the query as follows.
  • In the first way we need to use JSON.stringify to initially serialize your item to JSON, and afterwards determine the contentType so your worker comprehends its JSON.

As shown below code. In the second way we can use the dataType option to parse the received data. For the second way, we need to use the following code as follows.

Example

The third way, we realize numerous structures like ASP.NET MVC have inherent usefulness to deal with JSON.stringify as the contentType my circumstance is somewhat unique so perhaps this might help somebody later on. Now let’s see the example of ajax sending JSON for better understanding as follows.

First, we need to create a new project and assign any name that you want. After that we need to create the Html file with any specified name, here we created the index.html file and write the below-mentioned code. The output of the above program will be illustrated by using the following screenshot as follows.

We hope from this article you learn more about the jQuery ajax send JSON.

My code looks like this:. But on the server-side, I receive a data=mydata string, instead of the expected JSON. Firebug tells me the same.

Objects are converted to query strings which is what you are seeing here. You can use the JSON.stringify(obj) method to convert your Object to a String.

The code for the JSON object is available from: https://github.com/douglascrockford/JSON-js/blob/master/json2.js. Alternately, just pass the code you are using to create the object as a literal String, but I imagine this is just an example and you'll want to encode some object you've already created.

If you always have to send JSON in your application, then you can just execute this somewhere in your init and then use default $.ajax call as in your example, and it will always serialize as a JSON string instead of the Ajax default query string.

Here I use the JSON object mentioned above:. 124124 bronze badges. 124124 bronze badges. On one of my first big Javascript projects I learned how to use jQuery and especially its Ajax function.

Nowadays I use the library almost everyday for displaying, fetching and controlling the web. jQuery is a Javascript library which has been made to ease the development of JavaScript based websites and it offers massive framework for frontend web development.

One major and maybe the best part of it is Ajax, Asynchronous JavaScript and XML. In common language you can you can load data into a website without refreshing it. On this post I will demonstrate how to use this function. The basic syntax of jQuery Ajax is:.

Serverside

There are tens of settings you can use for the function.

What is jQuery ajax send json?

But usually we are interested in the url. The new syntax of jQuery ajax recommends everyone to use Promises. Which gives the function multiple callback options, like done and fail. alert("Ajax failed to fetch data"). In this example I will show you how to do Ajax with jQuery and how to process multidimensional JSON data table coming in through Ajax. This example is partly taken from a wine project which I was developing some time ago.

On the project we did a lot of coding with Javascript and the main function was jQuery’s Ajax. In that project were creating a software with HTML5, Javascript, CSS and on the serverside with PHP and MySQL.

The project wasn’t a great success but it taught me a lot about JavaScript. This example is about some of the technologies we were using on that project. You can test this example at https://www.lennu.net/demo/jqueryajax/. We will start with HTML skeleton with jQuery already embedded in it from Google.

Inside HTML we have three buttons, these buttons will be used for getting different kind of wines from our serverside. There is also a div where the wines will appear after being fetched from serverside.Add the Javascript code below to line 7.

Here we have the Javascript for the HTML. Basically we have a submit event that fires when a button is clicked.Next we take the value of the button clicked and send it to serverside.php with jQuery’s ajax()-function.

HTML

  • From this function we get back our JSON data which we’ll process on success. After that it’s simple if and else to append our #wines div. Add this to the HTML Skeleton in HEAD section. $(':submit').on('click',function(){// This event fires when a button is clicked. $.ajax({// ajax call starts. url:'serverside.php',// JQuery loads serverside.php.
  • data:'button='+$(this).val(),// Send value of the clicked button. .done(function(data){// Variable data contains the data we get from serverside. if(button'all'){// If clicked buttons value is all, we post every wine. $('#wines').append('Red wine: '+data.red[i]+'
    ');.
  • $('#wines').append('White wine: '+data.white[i]+'
    ');. elseif(button'red'){// If clicked buttons value is red, we post only red wines. $('#wines').append('Red wine: '+data[i]+'
    ');. elseif(button'white'){// If clicked buttons value is white, we post only white wines.

$('#wines').append('White wine: '+data[i]+'
');. returnfalse;// keeps the page from not refreshing .

Javascript

Now we need the serverside where Ajax will connect, create this file by the name of serverside.php if you wish everything to run smoothly.

  • This simple php gets clicked buttons value sent from our Ajax-function. After that we create a multidimensional data table.
  • Finally we do a PHP’s JSON-encoding and if else the right table to send back to Ajax. // Red wine table. // Combine red and white tables into one multidimensional table. // Finally depending on the button value, JSON encode our winetable and print it.
  • These codes will produce a working HTML site with jQuery doing some cool Ajax! You can use them as a skeleton when you are building your own Ajax based website.

I hope you have learned to do Ajax with jQuery from this example and can use this example maybe for something cool and useful!
