Yahoo! Query Language (YQL)

The Yahoo! Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services. With YQL, apps run faster with fewer lines of code and a smaller network footprint.

Yahoo! and other websites across the Internet make much of their structured data available to developers, primarily through Web services. To access and query these services, developers traditionally endure the pain of locating the right URLs and documentation to access and query each Web service.

With YQL, developers can access and shape data across the Internet through one simple language, eliminating the need to learn how to call different APIs.

How Do I Get Started?

1. Check out the YQL Console.
2. Read how to access YQL from your application.
3. Get your API Keys to sign your requests if you need them.

JS detecting event support in browsers

As you may know there is no easy way of detecting which elements supports which events across browsers. Kangax from Perfection Kills has come up with a very clever way of detecting them.

JavaScript

  var isEventSupported = (function(){
    var TAGNAMES = {
      'select':'input','change':'input',
      'submit':'form','reset':'form',
      'error':'img','load':'img','abort':'img'
    }
    function isEventSupported(eventName) {
      var el = document.createElement(TAGNAMES[eventName] || 'div');
      eventName = 'on' + eventName;
      var isSupported = (eventName in el);
      if (!isSupported) {
        el.setAttribute(eventName, 'return;');
        isSupported = typeof el[eventName] == 'function';
      }
      el = null;
      return isSupported;
    }
    return isEventSupported;
  })();

Use

isEventSupported(<"Type of Event>")

Debouncing Javascript Methods

What is debouncing anyways? Debouncing is any kind of hardware device or software that ensures that only a single signal will be acted upon for a single opening or closing of a contact. Imagine you have a form with a few elements that a user may access thru the tab key, on each element you have an onfocus event that will trigger an Ajax call to the server to acquire some data. You could just imagine how you could kill the server with all those Ajax calls! So that’s where debouncing comes into play. With debouncing your assuring that the method will be triggered in the element that the user intended to, although is not perfect it does work better than Throttling. Read more >>
