问题
This is not a duplicate question, I need only to decide if the better/fast/correct is to use attr or to use prop. The simplest and reliable way is checking into a list. A "list of element-name where the better is use prop(name) and/or a list where the better is use attr(name)".
PS: I am using jQuery 1.9+, and suppose that attr() is not a deprecated method.
Example of decisions (where the LIST have the answer):
- is better get ID value by
$(x).prop('id')or by$(x).attr('id')? - is better change title with
$(x).prop('title','BLABLA')or with$(x).attr('title','BLABLA')? - can I use
$(x).attr('selectedIndex')? - what property names have risk with "Cross-browser consistency"?
- there are some case (with Microsoft-IE p.ex.) where
$(x).attr('name')and$(x).prop('name')will return different things?
Perhaps a full list is not necessary, only a list of things that make some difference or risk for jQuery.

Have a look at https://developer.mozilla.org/en-US/docs/DOM/element#Properties and also consider that many properties are only available on special types of elements.
