You would use .attr() , as .prop() is more commonly used for boolean properties such as checked , selected , etc - though it is certainly possible with .prop it's arguably less clear as per your intent

Though I do believe that ultimately they are very similar (or used to be) functionality-wise

Just a note: the jQuery API site seems to follow the boolean 'sway':

.prop() - Examples use checked and disabled

.attr() - Examples use alt title and src
