When i use jQuery and prototype in a same page , the jQuery functions are not working. Can we use jQuery and prototype in same page ?
Yes - you need to use the jQuery.noConflict() or jQuery.noConflict(extreme) - methods - these turn back control of the $ shortcut to any other library that wants it. You will then have to call jQuery methods using the "jQUery" function name instead of $. jQuery is BY FAR the best library at "playing friendly" with other libraries - one of the big shortcommings of Prototype is the way it takes over $ with no way of getting it back.
