How do I implement JQuery noConflict

Question

I am using both javascript and jquery code on the same html page  For some reason  the jQuery library is stopping my native javascript code from working properly   I found this page  jQuery No Conflict  that says you can use a jquery noConflict to release   back to javascript  However  I m not sure how to do this     Specifically  I m not sure how to implement this correctly   Where does the the Jquery code go  where does the JS code go    My code is below    lt script type  text javascript  gt      noConflict         Code that uses other library s   can follow here   lt  script gt

In addition to that  passing true to   noConflict true   will also restore previous  if any  global variable jQuery  so that plugins can be initialized with correct jQuery version when multiple versions are being used

If you look at the examples on the api page there is this  Example  Creates a different alias instead of jQuery to use in the rest of the script    var j   jQuery noConflict       Do something with jQuery j  div p   hide       Do something with another library s        content   style display    none     Put the var j   jQuery noConflict   after you bring in jquery and then bring in the conflicting scripts  You can then use the j in place of   for all your jquery needs and use the   for the other script

jQuery noConflict will reset the   variable so it s no longer an alias of jQuery  Aside from just calling it once  there s not much else you really need to do  Though  you can create your own alias with the return value  if you d like   var jq   jQuery noConflict      And  generally  you want to do this right after including jQuery and any plugins    lt script type  text javascript  src   path to jquery js  gt  lt  script gt   lt script type  text javascript  src   path to jquery-plugin js  gt  lt  script gt   lt script type  text javascript  gt    jQuery noConflict         Code that uses other library s   can follow here   lt  script gt   lt script type  text javascript  src   path to prototype js  gt  lt  script gt    You can also go one step further and free up jQuery with noConflict true   Though  if you take this route  you ll definitely want an alias as neither   nor jQuery will probably be what you want   var jq   jQuery noConflict true     I think this last option is mostly used for mixing versions of jQuery  particularly for out-dated plugins when you want to update jQuery itself    lt script type  text javascript  src  jquery-1 4 4 js  gt  lt  script gt   lt script type  text javascript  src  jquery-older-plugin js  gt  lt  script gt   lt script type  text javascript  gt      var jq144   jQuery noConflict true    lt  script gt   lt script type  text javascript  src  jquery-1 6 4 js  gt  lt  script gt   lt script type  text javascript  src  jquery-newer-plugin js  gt  lt  script gt

You simply assign a custom variable for JQuery to use instead of its default    JQuery then wraps itself in a new function scope so   no longer has a namespace conflict    lt script type  text javascript  gt       jQuery     noConflict           Other library code here which uses          jQuery function       dom ready       lt  script gt

By default  jquery uses the variable jQuery and the   is used for your convenience  If you want to avoid conflicts  a good way is to encapsulate jQuery like so    function            function             alert    is safe                  jQuery
