CSS and Javascript Packing

While developing web applications, we use CSS and JS files. Now when the page opens, these get downloaded to the client side and take time doing so. Our aim should be that the size of these CSS/ JS files should be minimum so that the page opens up quickly. Here are a few links which help packing up these files.

Amazing sites. Try the Base62 encode and shrink variable option in JS packing for better results.

JQuery - Form content submission via Ajax

If you are using JQuery Ajax to submit data on a form, the regular way to do this is..

$(".submitDetails").bind("click",function()>

{

var dataString="name=Prabhjot&language=Java";
$.ajax({
type: "POST",
url: "someAction.do",
data: dataString,
success: function(data) {
alert("Ajax Submission Done"); }
});
});

As you see, i am trying to submit the form to a struts servlet. The issue is that i want to submit all the elements in the form back to the servlet. For this i would need to build the dataString manually ilke...

var dataString="name=" + $("#personName").val() + "&language=" + $("#languageName").val();

But this is very cumbersome when we have lots of form elements which need to be sent back.
jQuery provides us with the serialize() function to sort this out. This function will automatically create the dataString based on the form elements. So now all we need to do is:

var dataString=$("form").serialize();

and set dataString as the data in the ajax post. The actionForm in struts will be now be populated with these values.
