Benefits and Disadvantages of JQuery


Not too long ago I experimented with a jQuery occasion calendar on our Reserving System. Our earlier model makes use of ASP.NET to construct the reserving chart as an entire on the server after which renders the lot to the browser. It was a bit gradual and clunky, however labored.

I needed to have a PHP model of the Room Reserving System so did a fast port from the ASP.NET C# to PHP, after which I dropped the jQuery fullcalendar element on the web page. I used an internet service for the info which was nonetheless written in C# towards a Microsoft SQLServer database.

On slightly extra tinkering and refactoring, I discovered I may do away with nearly all of the PHP/.NET code because it was solely used to initialise the web page. Now I used to be left with a web page with successfully simply HTML and JavaScript utilizing a AJAX to name a JSON information feed from a REST internet service.

The consequences had been gorgeous! In addition to wanting nicer, the velocity of replace was unimaginable – like a Home windows utility. In fact, that is achieved as a result of the web page runs nearly completely within the browser and calendar navigation might request simply small quantity of information utilizing AJAX towards the net service.

May I write all the utility like this?

It jogged my memory of programming within the 1990’s. Net pages had been HTML with a little bit of JavaScript; we then added slightly ASP to get information from a database and stick that on the web page. Getting information on a web page was comparatively simple even then; the issue has all the time been after we need the consumer to work together with it. Even the straightforward stuff, like solely permitting a numeric digit right into a textual content field, checking for legitimate date, information grids and even easy popups weren’t as simple as in a Home windows app.

Why? As a result of pure JavaScript is gradual to put in writing, it is simple to make errors, tough to debug and also you’re on the mercy of whichever browser the consumer has choice for.

Programmers seemed for different means and located them in applets, DLLs,.NET, JSF and different applied sciences and server frameworks. I moved on to ASP.NET as a result of it took the drudgery out of programming, mechanically generated the JavaScript and was simple to put in writing and debug; a a lot friendlier mannequin. It nonetheless is, however jQuery and different JavaScript Frameworks at the moment are threatening the established order.

Microsoft has adopted jQuery in a giant approach and it’ll exchange the AJAX Toolkit. Many software program builders have already adopted jQuery or YUI. Mixed with HTML5, these JavaScript Frameworks might pressurise Flash and Silverlight. jQuery actually has a spot within the close to way forward for internet improvement

Can I simply use jQuery and nothing else? Possibly – however not but, not completely. As impressed as I’m with jQuery, I really feel it is simply one of many instruments within the software program developer’s toolbox. I am going to use jQuery increasingly more however I will be utilizing.NET and PHP too. Here is how I summarise it:

For and In opposition to jQuery and JavaScript Frameworks


  • Good Consumer Expertise, near a Home windows GUI
  • A lot simpler to make use of than plain JavaScript
  • Spectacular velocity
  • Coders haven’t got to fret about Browser variations
  • Reduces Server Load as fewer round-trips
  • Extensively used, good group assist
  • Many elements already developed
  • Open Supply


  • You most likely nonetheless want a Server framework for initialisation and Session administration
  • You want one other app to provide your information (like an internet service) written in one other language (like.NET, Java or PHP)
  • In bigger apps, slower to code than PHP or ASP.NET
  • You have to perceive CSS
  • Can nonetheless be tough to debug, particularly if scripts intervene with one another.
  • Supply code is tough to guard
  • Is usually a little cryptic to learn

If you have not tried jQuery then you must undoubtedly achieve this. It is simple to get into and can improve your internet functions
