Modify attribute of all elements in class

I checked "select_all", which successfully checked all checkboxes with class "checkbox_read". I then unchecked "select_all" which successfully UNchecked all checkboxes with class "checkbox_read."

Then I checked "select_all", again which failed to check all checkboxes with class "checkbox_read."

I found this bug after upgrading my JQuery library from 1.7.1 to 1.9.1. when I downgraded, the error did not manifest itself.

Code is below:





$('.checkbox_read').attr('checked', 'checked');




$('.checkbox_read').attr('checked', false);

When working with attributes whose value is of boolean type, it is recommended to use **prop** instead of **attr**. There is a detailed discussion on their differences in the API documentation. Here is the jsfiddle fork which uses prop instead of attr and it works as expected in jQuery 1.9.1
