Why should you use jQuery
Posted on | September 3, 2008 | No Comments
If you ask me one year ago “have you seen jQuery” my answer would be “have you seen what?”
If you ask me six months ago I would say “I heard about it but I don’t see any benefit in using it. I know javascript well enough to write my own code”.
And I was sooooo WRONG.
I just finished small project for my friend www.jardinsdesreves.pl and I decided to give it a try.
The benefit: my js file is only 170 lines long.
I just want to show you couple benefits of this wonderfull framework.
FORMS:
I have never seen a simpler way to submit forms via ajax.
Just look at the simple example:
1 2 3 4 5 6 7 | <form> <input type="hidden" name="id" value="2"> <input type="hidden" name="save" value="1"> Title: <input type="text" name="form_title"><br> Content: <textarea name="form_content" cols="25" rows="8"></textarea> <input type="button" value="Save changes" onclick="sendForm('text_save.php');"> </form> |
1 2 3 4 5 6 7 8 9 10 | function sendForm(post_url) { var request = $("form").serialize(); $.post(post_url, request, function(data) { formResponse(data); }); } function formResponse(resp_data) { $("#message").text(resp_data); } |
As you can see jQuery does all job for us.
There is only one requirement - each form element needs to have a name (not id).
serialize() function does great job and will post all form to ‘text_save.php’ where we can do processing and show response to the user.
In the next article I will show you how to use great jQuery plugin ‘ajaxfileupload.js’ to upload files.

This is just a beginning.
I hope to find enough time to write some articles about web development (PHP, Javascript, CSS, Flex …) and my hobby photography.
I spend a lot of time writing code and even more time googling around for help and solutions. I know how difficult it is to find something useful. That’s why on my blog I will post only useful information and I will try not to copy anything that is already posted on other blogs.
Don’t expect to find a new post every day but if you have any questions or comments to my articles I will respond ASAP
Lets get started
