Data Gone Wild? No More. Data Gone Wild? No More.
How do you maintain complex data scenarios, while ensuring reliable connectivity for your HTML5 apps? The latest release of Telerik Kendo UI® is packed with data management and export capabilities, offline data storage and modern mobile UX solutions. See them live!.

The attributes property is available on all HTML elements, and we can use it in conjunction with the hasAttributes() method, which returns a Boolean value. hasAttributes() (note the "s" at the end) seems to have gone unnoticed by a lot of developers, possibly confusing it with hasAttribute() (no "s").

While the well-known hasAttribute() method takes an argument, which is the attribute you want to test, the hasAttributes() method does not does not take any arguments, so it's just a true or false test to see if any attributes exist.

After testing to see if an element has any attributes, we can collect them using the aforementioned attributes property. This property returns an array-like live DOM collection.

Here's a quick-and-dirty script to collect and display all attribute/value pairs from all the div elements on a page:
 
var divs = document.getElementsByTagName('div'),
    op = document.getElementsByTagName('output')[0],
    i, j;

for (i = 0; i < divs.length; i++) { 

  if (divs[i].hasAttributes()) {
    op.innerHTML += '<p><b>Element #' + 
                    (i + 1) + 
                    ' has the following' +
                    ' attribute/value pairs:</b>';
    for (j = 0; j < divs[i].attributes.length; j++) {
      op.innerHTML += divs[i].attributes[j].name + 
                      ': ' +  divs[i].attributes[j].value + 
                      '<br />';
    }
    op.innerHTML += '</p>';

  } else {
    op.innerHTML += '<p><b>Element #' + 
                    (i + 1) + 
                    ' has no attributes.</b>';
  }
}

(JS Bin example)

The attributes property is supported everywhere, including back to IE6. The hasAttributes() method is supported everywhere including IE9+, so you might need a shim if that's not good enough.

Before I Go...

Want an easy way to grab the audio off any YouTube video? Just add the word "sound" to the front of the URL (after the "www."), which is based on the service by soundyoutube.com. The only catch is that you have to use http not https, otherwise you'll get an error/warning. Here's an example.
