Jquery .attr()

-
.attr(attributeName)
Get the value of an attribute for the first element in the set of matched elements.
.attr(attributeName, value)
Set one or more attributes for the set of matched elements.
Returns: String
.attr(attributeName)
attributeName The name of the attribute to get.
Get the value of an attribute for the first element in the set of matched elements.
The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. In addition, .attr() should not be used on plain objects, arrays, the window, or the document. To retrieve and change DOM properties, use the .prop() method.

Using jQuery's .attr() method to get the value of an element's attribute has two main benefits:

Convenience: It can be called directly on a jQuery object and chained to other jQuery methods.
Cross-browser consistency: The values of some attributes are reported inconsistently across browsers, and even across versions of a single browser. The .attr() method reduces such inconsistencies.

Effective cost per thousand impressions (eCPM) is the amount of revenue you can expect to earn from AdSense for every 1000 impressions shown on your site. Since eCPM helps you measure how well your ads are performing, we often hear questions from publishers about the factors that impact this metric and how it relates to their earnings. If you're using the new interface, you'll see that your reports show RPM (revenue per thousand impressions); RPM is just another term for eCPM, and it's calculated the same way, so we use these two terms interchangeably. To help provide some clarity, we're kicking off a two-part video series with more insights into how eCPM is calculated in order to help you maximize earnings. With the help of AdSense optimization specialist, Matthew Carpenter Arevalo, we'll show you the factors that affect eCPM, how to track user behavior and traffic patterns, and ...
