I’m curious what the minimum required jQuery version is to use with the jQuery UI Range Slider plugin.
Testing it with 1.5.7 I get slider() is not a function, however with jQuery 1.7 it works fine.
In addition, are their any tweaks that I could make in order to make the slider work with an older version of jQuery?
You sure nothing else is wrong?
Created a test on jsfiddle: http://jsfiddle.net/ZeaeY/
Seems to work fine with jQuery all the way back 1.3.2 (older and it fails)
(Testing with jquery-ui 1.8.18 – since you didn’t write your version)
