While working on a JavaScript plugin I decided that it is great when plugin informs user about what it have done or on what it is working right now. This functianality is the same as some events in javascript like 'click', 'keyup' or others. And the plugin should use it's own events.

But how to fire own crossbrowser event?

Few weeks ago I saw a piece of code on my friend's website. Main task of this code - open foreign links in a new page.

$(document).ready(function(){
    $('a').each(function() {
        var a = new RegExp('/' + window.location.host + '/');
        if(!a.test(this.href)) {
            $(this).click(function(event) {
                event.preventDefault();
                event.stopPropagation();
                window.open(this.href, '_blank');
            });
        }
    });
})

Do you think this code is correct? As for me - I don't think so.

I can add few lines to this code to improove it:

• "/*" before this code;
• "*/" after this code;

Tones of developers fighting with unneeded kilobytes of data on their web projects to increase their performance. Minimization of pages weight, reducing the number of requests, place of including scripts and many other things affect the speed of loading and displaying the pages. Developers using css3 sprites to reduce the number of queries when page loads. Base64 image encoding also using in this context and in some way it is more convenient.

Several months ago I encountered a problem - "How to abort() all current requests on the project page?". If you have a project built on AJAX you'll definitely need this functionality. Moreover, if your project is not built entirely on AJAX, but uses it in some cases to accelerate the navigation on the project you would not have prevented the use of abort() for such requests.

In a single use of AJAX it is simple. The XMLHttpRequest has a abort method, which cancels the request.

// creating our request
xhr = $.ajax({
	url: 'ajax/progress.ftl',
	success: function(data) {
		//do something
	}
});

// aborting the request
xhr.abort();

But what if we have a lot of requests and we wand to abort all of them?
