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.

They vary from browser-to-browser, but here's IE's list...http://msdn.microsoft.com/en-us/library/ie/hh773183(v=vs.85).aspx

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.
