Description
The .attr method is a convenient and powerful way to set the value of attributes
especially when setting multiple attributes or values returned by a function. Let's
consider the following image:
.attr(attribute, value)
We change the alt attribute by putting 'alt' followed by a comma and the new
value inside the .attr method's parentheses:
$('#greatphoto').attr('alt', 'Beijing Brush Seller');
We can add an attribute in the same way:
$('#greatphoto').attr('title', 'Beijing Brush Seller – photo
