Download documentation - Like a normal file download in the main window an iframe will never fill with content when a successful file download occurs. At least that's my conclusion after trying to download 5 files with the same name but different extensions.

 

The common use of Ajax in web development has created a dynamic yet fluid Internet. Designers often build mockups which incorporate Ajax-based elements such as lazy loaders, tabbed widgets, and other similar page elements. In this tutorial I want to delve into a basic example of handling Ajax development with PHP on the backend. Normally you would connect this into a database using an engine like MySQL, but for this tutorial I want to focus on handling the response from PHP, and how you can use this response to append new content onto the page. Take a peek at my live sample demo to get an idea of what we are creating. The jQuery is a more simplified way of handling this HTTP request, and you have a large index of documentation explaining each of the various options. I also downloaded a local copy of jQuery along with a blank JavaScript file named ajax. Someuser's Profile Joined Nov 1st, 2013 - 18 Followers Follow.... Load more followers Above I have combined two bits of code from my HTML which are located at different sections in the page. The anchor link using an ID of followbtn will trigger an event callback when clicked. The same goes for the other anchor link, morefllwrs. However these events will run different callback functions, and they both expect a different type of request using Ajax. We can start by looking at the follow button example and how this behavior works. Simple Ajax Actions Many social networks like Twitter and Pinterest use Ajax to auto-update the page once you follow a new profile. This would obviously require connecting into a database for any live application, but for this example we can write the PHP as if we already connected into the database. You will notice the Ajax request has a lot of different options — certainly not the whole catalog but enough to get us going. It should be organized like a JSON string with key:value pairs. Usually helpful when debugging issues between JS and PHP. We only want to update the page with a success message if PHP has created the follow relationship. You might also notice we can update the number of followers on the page using a JavaScript method. We can see this person has 18 followers and only 10 are displaying by default. Each click will load 5 more followers until we have loaded them all. This is formatted in a way that jQuery can easily loop through each follower and then append them into the list. All of this info could be pulled out of MySQL and would appear in similar syntax using something like. Loading Followers with Ajax This last bit of code inside ajax. Notice that my selector is targeting the page body and we pass the morefllwrs button as a parameter to the method. The purpose is to handle clicks on the same link which gets dynamically appended into the page. So right when the DOM loads jQuery will target the first link, and a user will click to load more followers, but in order to get another button to appear we need to add HTML onto the page using jQuery.

By using the whole body as our selector it will keep listening for the click event including new elements which are added to the page after loading. In fact, the biggest difference will be found inside the success function callback since we are using a type of jQuery loop. The response from PHP is held in a JS variable called json. We turn each array object inside the JSON string into a new variable called item. Since this is a very basic example the objects only have two keys — item. Any real-world example might include many more values. Once we hit the last JSON entry then we know there are no more pages. Web development has advanced so quickly with the rise of open source projects like jQuery. Feel free to download a copy of my demo files and see if you can build any similar interfaces on your own web projects. For web-based email this meant that users had to manually reload their inbox to check and see if they had new mail. This had huge drawbacks: it was slow and it required user input. This was hugely inefficient. By 2003, all the major browsers solved this issue by adopting the XMLHttpRequest XHR object, allowing browsers to communicate with the server without requiring a page reload.
