javascript - jQuery Plugin Check Version

Question

When writing a new jQuery plugin is there a straightforward way of checking that the current version of jQuery is above a certain number? Displaying a warning or logging an error otherwise.

It would be nice to do something like:

jQuery.version >= 1.2.6

in some form or another.

Answer 1

Here is a check I used to make sure the user was using at least v. 1.3.2 of jQuery.

if (/1.(0|1|2|3).(0|1)/.test($.fn.jquery) 
                    || /^1.1/.test($.fn.jquery) 
                    || /^1.2/.test($.fn.jquery)) 
{
    //Tell user they need to upgrade.
}
